About This Manual

This manual describes how to install and operate the DX-IRIS Infrared Interface System. The IRIS is an infrared transmitter that makes it possible for a powerchair user to control infrared devices with the same input device used to control the chair.

This manual also describes how to install and operate the DX-PCMR PC Mouse Receiver, an infrared receiver that gives the user control of a computer mouse through the IRIS. The procedures in this manual provide guidelines on how best to configure a DX system that incorporates the IRIS, or the IRIS plus PCMR.

This manual has been written for dealers, therapists, and other installers of the IRIS/PCMR system. Before installation, it is assumed that a correctly functioning DX system has already been installed, and that the installer of the IRIS/PCMR is

knowledgeable about the operation of the other modules in the system. For more information about other DX modules, refer to the manuals for those products.

Throughout this manual, the following symbols will help you identify the purpose of the associated paragraph:

NOTE

Notes provide supporting information for the preceding paragraph or section. You should follow this information to install, configure, and use the IRIS safely and efficiently.

WARNING

Warnings provide important information for the preceding paragraph or section. You must follow this information to install, configure, and use the IRIS safely and efficiently.

Section 1 Introduction 1

1 Introduction

The IRIS is a DX-compatible module that can add infrared functionality to any DX-equipped wheelchair system. The IRIS can control a wide range of off-chair devices, including:

• most household appliances normally controlled with a hand-held infrared remote control.

• most personal computers (PCs).

• most home automation devices that accept infrared commands.

• various infrared devices manufactured by Gewa.

The IRIS is controlled from the same input device used to drive the chair, such as:

• standard proportional joystick

• heavy-duty switched joystick

• switch input device

• finger control

• sip-and-puff device

Exploring an IRIS System

An IRIS system requires the following DX modules:

• The DX Power Module provides power to the motors.

• The Specialty Controls Remote (SCR) shows the menu of IRIS commands and provides visual feedback to the user through its LCD screen. To use the IRIS, the wheelchair system must have an SCR MK2 as its master remote. (See Note 1.)

• A DX Secondary Remote is the input device used to control all on- and off-chair functions.

• DXBus cables carry power and communications between modules of the DX system.

• A DXBus 4-way socket provides additional DXBus sockets to connect the DX modules, as needed.

• Other optional DX Modules provide additional functionality such as lighting, seating, and other on-chair controls, as needed.

To set up and configure the IRIS System, you also need the Dynamic Wizard (see Note 2) and DX Hand-Held Programmer (HHP).

NOTES

1. The IRIS must use a Mk2 SCR as its master remote. Older SCRs are incompatible with the IRIS. Mk2 SCRs can be identified by a label along the top of the jack sockets.

2. Unless specified, versions of the Wizard later than 3.1b do not support

programming of the SCR. Check what version of the Wizard you have by launching the Wizard and selecting Help–About. Check the DynamicMobility web site for other versions of software, software updates and patches.

Section 1 Introduction 3

IRIS Installation Overview

This procedure outlines how to prepare for and set up the IRIS, assuming you have already set up the other DX modules.

(12)

STEP 1 – Plan the installation Assess the user’s capabilities, preferences and equipment.

STEP 2 – Set up the SCR menu structure

Sketch out a detailed SCR menu structure to meet the user’s requirements, and use the Wizard to set up screens. Review your set-up with the user, and make any

adjustments needed.

STEP 3 – Install and connect the IRIS

Physically install the IRIS and any other appliances to be controlled by the IRIS at the user’s site, and download the SCR menu structure.

STEP 3A – Install and connect the mouse receiver, if used

If a mouse receiver is part of this

installation, install it at this time. Refer to Section 7 if installing the PCMR. To install Gewa’s mouse receiver, refer to the documentation that came with the product.

STEP 4 – ‘Learn’ Program the IRIS to read the infrared codes that are transmitted by the appliance remote controls.

STEP 5 – Test and tune Test and tune the infrared commands the IRIS has learned.

STEP 6 – Link Link the infrared codes to the screens in the SCR menu structure.

(13)

Section 2 Preparation 5

2 Preparation

Step 1 – Planning the Installation

No two wheelchair users are alike. Thus, the first step of any IRIS installation is to become familiar with the user and his or her environment. What are the user’s capabilities and restrictions? What are the user’s habits, interests and activities?

With what frequency and in what order does the user pursue these activities? What controllable devices are available in the environment, and how can they be used to facilitate the user’s activities?

The Wizard upgrade for IRIS includes several sample programs for hypothetical users. Three of these, John’s Program, Mary’s Program and Peter’s Program, are for users operating primarily in a basic one-room environment. These programs are similar except for the control method used — Joystick Only, Joystick Plus Mode Switch, and Scanning, respectively. The fourth example, Susan’s Program, is for a more active user in a more complex environment.

The box below describes John and his environment. Over the next few pages, John’s situation and his Program are used to illustrate the kind of planning process that you, the installer, must follow when planning an IRIS installation.

Introducing John

Activities and Interests. John spends most of his time in his own room, driving only short distances on his own. He has a computer, a television and a mini stereo system, and loves to “channel surf”, chasing the world’s news on the Web, TV and radio. Although his stereo system includes a CD player, John has not used it yet, but thinks he might like to in the future.

Environment. John’s room is fitted with infrared-controllable lights, window, curtain and intercom. His chair is fitted with an adjustable seat and footrests, a reading light, a help light, and a nurse call switch. He also occasionally uses a two-switch on-chair communicator.

John will use a joystick to control all on-chair and off-chair functions, but he can also operate a panic/stop switch.

(14)

Step 2 – Setting Up the SCR Menu Structure

The next step is to sketch out and set up a menu structure on the SCR that allows easy and intuitive navigation through the IRIS commands. Before you can do this, however, you must have an understanding of what the SCR menu structure is and how it works.

Introducing the SCR Menu Structure

To set up an SCR menu structure, you use the Wizard software to define:

• How many appliances are to be controlled

• Which functions of each appliance are to be controlled

• The most convenient order in which options are to be presented

• The text to be displayed on the SCR screen for each appliance and function. All text that appears on the SCR screen can be customised and can include:

• many languages

• appropriate terminology references

• personal preference

From the SCR main menu, the user can access all wheelchair options that are set up for control with the input device. The menu structure of the SCR consists of three layers: modes, submodes and functions.

• Modes are defined on the first menu layer. Modes include such options as driving, seat adjustment, and infrared control.

• Submodes are defined on the next menu layer. Only infrared control modes require submodes, because of the complexity of this mode type. Here, you can organise functions in a way that makes sense in the user’s environment.

Depending on the particular situation, you can define the various infrared appliances to be controlled, such as a television and a computer, or you can group functions according to location and usage, such as for the office, living room and bedroom.

• Functions are defined on the third menu layer. They are the specific options the user can control on each appliance. For example, a seat adjustment mode might have a function to raise and lower the seat, while the television submode of an infrared control mode might include functions to adjust the volume up and down, turn the power on and off, and select channels.

The SCR displays arrow icons to assist the user in navigating through the menus.

(15)

Section 2 Preparation 7 Choosing the Control Option

Depending on the user’s capabilities and preferences, there are three methods, or control options, with which the user can navigate through the modes, submodes and functions of the SCR menu structure. These control options are called Joystick with Mode Button, Joystick Only, and Scanning. At the mode level, these control options provide different functionalities, as shown in the following diagram; however, they work identically at the submode and function levels (shown for the Joystick Only option).

Considering System Limits

In addition to the user’s needs, you must also consider the limits of the SCR menu structure:

• Each menu structure can have a maximum of 8 modes.

• Each infrared control mode can have a maximum of 15 submodes.

• Each mode or submode can have maximum of 15 function screens.

• There is an overall limit of 95 infrared functions (usually implemented as two functions per screen), plus the mouse control function.

(16)

John’s SCR Menu Structure John’s Equipment

John’s SCR Menu Structure Requirements: 1 Room + ECU + Seat + Computer To accommodate his activities and environment, John needs an SCR menu

structure with four different modes: He needs a slow/indoor drive mode for driving his chair, an infrared control mode to control the equipment in his room using the IRIS and the PCMR, an environmental control mode for his on-chair lights, beeper and communicator, and a seat control mode for the actuators that provide seating functions.

Because John normally will use a joystick to control all functions, his SCR control option is set to Joystick Only, but a stop/mode switch is also connected to the Stop/Mode socket. John usually presses the switch when he wants to exit quickly out of mouse control mode or drive mode, because his timeout is set to the maximum of 99 seconds. This long timeout optimises his usability of computer functions, because he will not be thrown out of mouse control mode too often.

John will spend most of his time using the infrared control mode, and within its submodes, he expects to spend the most time operating the television and the radio.

The computer submode is placed first on the list of infrared submodes so that while John is surfing the Web, he can quickly get back to mouse operation after a timeout.

The CD functions are placed at the end of his radio submode, because he expects to give them low use.

Example: SCR Menu Structure for John’s Program

On the following page, a diagram shows the planned SCR menu structure for John’s program.

Using the Wizard to Create an SCR Menu Structure

To create and edit an SCR menu structure, you must use version 3.1b of the Wizard. If you do not have this version of the Wizard, refer to Appendix A, Installing an IRIS-Compatible Wizard, for more information.

1. Launch the upgraded Wizard.

2. Select File–New from the menu bar to display the Choose Wheelchair Program screen. Click DX Templates in the Folder, and select a template program suitable for the IRIS.

3. Click OK to display the main Wizard screen. The Program Modules box shows the list of DX modules associated with the template.

(19)

Section 2 Preparation 11 4. Click the File–Save button to save the template program with a new name.

Enter the new name in the Program Name box, double-click Folder and select a folder for the new program, then click OK.

5. Add an Identification and Program Descriptions, if desired. Double-click on the Specialty Controls Remote program module to begin editing the SCR

programmable settings for the new program.

(20)

6. The SCR Settings screen appears. Select the correct Control Method for the user.

7. Click the Define Modes and Functions tab. Here you can set up the SCR menu structure. The box on the left of the screen shows the list of default modes, or main menu, associated with the template you used.

NOTE The Control Options and Miscellaneous Text tabs are also used to program other SCR functions unrelated to the operation of the IRIS. For more information, refer to the DX-SCR Installation Manual.

Of course, before the SCR program is complete, you must set up all chair and driving parameters suitable for the user’s equipment, as well as IRIS functionality.

(21)

Section 2 Preparation 13 A Simplified Menu Structure Example

This figure shows part of a simplified menu structure. In the following sections, as we move through the process of setting up an SCR menu structure, we will refer to this example structure.

(22)

Defining Modes

The list of modes defines the main menu of control options that the user can scroll through, either by pressing the Mode button on the SCR front panel, or by using another mode switch in the DX system.

If the modes on the list are not exactly what you need for the particular menu structure you are defining, you can change the number of modes, the type of modes, and the order in which they are listed.

To change or remove a mode

1. Click the mode you want to change or remove. The mode is highlighted in blue, and a small down-arrow appears to the right.

2. Click the down-arrow to display a list of alternative modes to choose from. If you want to remove the mode, select [Mode Unused].

To change the order in which modes appear on the SCR screen 1. Click the mode you want to shift.

2. Click the Shift Mode buttons to move the mode up or down on the list.

(23)

Section 2 Preparation 15 Menu Structure Example: Modes

This screen shows the SCR set up to support the five modes in the simplified menu structure example: three drive modes, a seat control mode, and an infrared control mode.

(24)

Defining Submodes

To define IRIS infrared submodes, click an infrared control mode to display the Submode box in the middle of the Define Modes and Functions screen. This box contains the list of submodes currently set up in the SCR menu structure. If no submodes are defined, the default entry, ‘IRIS Appliance’, appears on the list.

If the submodes on the default list are not exactly what you want for the menu structure you are defining, you can add, remove, rename, or reorder them:

To add another submode 1. Click an infrared control mode.

2. Click the Add Submode button. A new submode with the default name,

‘IRIS Appliance’ is added to the list.

To remove a submode

1. Click an infrared control mode.

2. Click the submode you want to remove.

3. Click the Remove Submode button. (Note: You cannot remove the last IRIS Appliance. Instead, change the mode to [Mode Unused].)

(25)

Section 2 Preparation 17 To change the name of a submode

1. Click an infrared control mode.

2. Click the submode you want to change. The first line of the LCD TEXT box at the bottom-left of the Wizard screen shows the name of the submode as it will appear on the SCR screen when the user selects that submode.

3. Click in the first line of the LCD TEXT box and change the submode name as desired, editing the text as you would using a word processor. The new name of the appliance automatically appears in the Submode box, with leading spaces omitted.

Menu Structure Example: Submodes

The simplified menu structure example includes four infrared submodes to control a television, a video, a computer, and a stereo.

To create this portion of the example menu structure, follow these steps:

1. On the Define Modes and Functions screen, click the INFRARED CONTROL mode. One

‘IRIS Appliance’ entry appears in the Submode box.

2. You need to add three more appliances, for a total of four. To do this, click the Add Submode button three times.

(26)

3. Now, rename these appliances with the words you actually want displayed on the SCR screen. To do this, click the first appliance you want to rename. The LCD TEXT box shows the text that will appear on the SCR.

Click in this area and change ‘IRIS Appliance’ to ‘TELEVISION’. The new name of the appliance automatically appears in the Submode box.

4. Select each of the other appliances and rename them as shown in the example SCR menu structure.

(27)

Section 2 Preparation 19 Creating a Computer Mouse Submode

If you are adding a submode to control a computer mouse, you must perform these additional steps.

1. Click the submode that you have created to control the computer mouse, then click the Options button near the bottom of the screen.

2. The IRIS Appliance Options screen appears.

Click Yes to select Mouse, then click OK to close the screen.

3. The default name in the function box changes to

‘Operate with JS’. Click on this function name.

If the control method is ‘Joystick Plus Mode Button’, the fourth line of the LCD TEXT box reads: Mode to exit.

If the control method is ‘Joystick Only’, the fourth line displays the countdown of the timeout: Time to exit: @@.

MOUSE

< Sip SOFT Puff >

v HARD ^ Time to exit: @@

4. Edit the function name and the other text in the LCD TEXT box to suit your application. For example, if you have a sip-and-puff rather than a joystick, you might enter something like this.

5. The screen on the SCR is now set up to control the mouse cursor using the input device.

(28)

Defining Functions

To define functions for a mode or submode, click the mode or submode name to display the Function box at the right of the Define Modes and Functions screen. This box contains a list of the functions set up for that mode or submode. If no functions have been defined yet, a single ‘Output 1’ entry appears on the list.

To add another function

1. Click the submode to which you want to add a function.

2. Click the Add Function button to add as many function screens as you need, up to a maximum of fifteen.

To remove a function

1. Click the function you want to remove.

2. Click the Remove Function button. (You cannot remove the last function. Instead, delete the submode.)

To change the name of a function

1. Click the function that you want to change. The second line of the LCD TEXT box shows the name of the function as it will appear on the SCR screen.

2. Click in the second line of the LCD TEXT box and change the name of the function as desired, editing the text as you would with any word processor. The new name automatically appears in the Function box, with leading spaces omitted.

(29)

Section 2 Preparation 21 To set the number of functions the screen controls

A function screen can control either one or two functions. The default is 2.

1. Click the function that you want to change.

2. Click the Options button.

3. Select 1 or 2, depending on the number of functions you want the screen to control.

NOTE

Remember that each mode or submode can have maximum of 15 function screens.

For more information about size limits, see “Considering System Limits” earlier in this section.

Menu Structure Example: Functions

The simplified menu structure includes four functions to control the stereo: Power, Volume, Play/Stop, and Track Select.

To create this part of the simplified menu structure example, follow these steps:

1. On the Define Modes and Functions screen, click the Stereo submode. One

‘Output 1’ entry appears in the Function box.

2. For the structure shown in the diagram, you need to add three more functions. To do this, click the Add Function button three times. Each new function is given a default name, ‘Output 2’ through ‘Output 4’.

(30)

3. Now click each function name, and change the screen text as need by editing the LCD TEXT box. Note that the text on the second line appears in the Function box as a label for the screen.

(31)

Section 2 Preparation 23 4. Note that this screen has two functions, Up and Down. If the screen had only one

function, you would need to click the Options button and change the setting for the number of functions from the default of 2 to 1.

5. Click OK to accept the changes you have made to the program. (Click Cancel if you do not want your changes saved. If you click Cancel, you will lose all changes since you opened the SCR Settings window.)

6. You have now set up four submodes and four functions for one of the submodes in the simplified SCR menu structure. If you want, go through and set up each mode, submode, and function for the entire structure, or add and delete items to suit your own applications.

(32)

Saving the Wheelchair Program

To save the wheelchair program for future use, perform these steps:

1. With the modified wheelchair program open, go to the File menu and select Save to overwrite the current program or Save As to save the program with a new name.

2. When the dialog box appears, type a name in the Program Name box:

Example: If you want to save your work on the simplified menu structure example, you might enter a name like ‘IRIS Manual Example’.

3. Select a Wizard folder to save the wheelchair program into or, alternatively, create a new folder by clicking the New button.

(33)

Section 2 Preparation 25 NOTE If you have OEM dongle access, you can create wheelchair templates. Templates

cannot be overwritten by a Wizard with lower access than OEM level. They are signified by an asterisk * beside the wheelchair program name in the New, Open and Save dialog boxes.

To save a program as a template, check the Standard radio button before you save the wheelchair program.

Reviewing the SCR Menu Structure with the User

The last step in the planning process is to review the proposed SCR menu structure with the user. This can be done in several ways, depending on the user’s aptitude and equipment availability:

• Go through a detailed chart of the menu structure with the user, such as the chart illustrated earlier in this section for John’s Program.

• Go through each screen of the new program on the Wizard, showing the user the text in the LCD TEXT box.

• Write the new program to an SCR and let the user go through it with a connected input device. Even though the structure does not yet control any IRIS

functionality, the user will be able to navigate through the menus and make comments that can help you refine the structure.

WARNING

Before loading the new program to the user’s own SCR and chair, be sure you have also correctly set all chair parameters (Power Module and Attendant Control Module settings), and all driving parameters for the user’s drive profile (Drive Mode–Options)

(34)

(35)

Section 3 Physical Installation 27

3 Physical Installation

Step 3 – Installing and Connecting the IRIS

The IRIS has been designed to transmit in a wide range of directions, making the physical mounting position of the IRIS relatively non- critical.

An ideal way to mount the IRIS is to attach it to the back of the SCR with the Velcro supplied.

This allows the IRIS to transmit in front and to each side directly, and to the rear by reflection off walls, floor, ceiling and objects.

Alternatively, it can be mounted anywhere that allows a wide unobstructed transmission area, preferably forward. For outdoor or difficult environments, such as large open-plan areas, the user should be able to point the IRIS fairly directly at critical receivers, such as door openers.

(36)

All power and communications are transmitted through the DXBus cable. Plug the DXBus plug on the end of the IRIS cable into any available DXBus socket. Route and secure the cable to prevent mechanical damage and snagging. The cable should run downward away from the IRIS.

To check that the IRIS is connected and functioning correctly, power up the system by pressing the I/O button on the SCR, and check that the red status light on the side of the IRIS comes on and remains steady.

In addition to the IRIS, be sure that the infrared appliances the IRIS will control are installed and their remote controls available.

Write the complete prepared program to the SCR system. The program must include correct settings for all chair parameters (Power Module and Attendant Control Module settings) and driving parameters (Drive Mode–Options).

Step 3

A

– Installing and Connecting the Mouse Receiver

If a mouse receiver is part of this installation, install it at this time. Refer to Section 7 for the procedure on how to install the DX-PCMR. To install Gewa’s mouse receiver, refer to the documentation that came with the product.

(37)

Section 4 Programming the IRIS 29

4 Programming the IRIS

So far you have set up a menu structure in the SCR. If you were to use the SCR now you could navigate through the menus, but you could not control any devices.

For each function defined in the menu structure, you must now program an infrared command to be transmitted when the command is selected with the input device.

The IRIS is basically a storage block for infrared codes.

One way to understand how the IRIS stores these codes is to compare it to a filing cabinet in which many infrared codes can be learned and filed.

This filing cabinet has 80 slots available to store infrared codes (or commands). Using the IRIS learning process, you can file infrared codes in these slots until they are all used.

The filing cabinet also has 128 slots that are already loaded with codes to control GewaLink devices (see Note).

The IRIS Code Reference List and Gewa Code Reference List provided at the end of Section 5 are forms you can use to record the programmed codes.

NOTE Gewa is a third-party supplier of infrared- controlled devices that perform many common home automation functions. For information on how to install and configure Gewa appliances, refer to the information that came with your Gewa product.

The GewaLink number the IRIS displays is the number as published by Gewa, plus 1.

For example, Gewa refers to code 62 as being blank; thus you cannot allocate the IRIS’s Gewa infrared code 63.

(38)

After learning these codes and assigning them to slots, you must then associate or

‘link’ each of the functions in the SCR menu structure to the corresponding code stored in the IRIS:

NOTE You can link more than one SCR menu function to an IRIS slot. For example, if you have created functions for Play on function screens called Tape, CD, and DVD, but the remote control has only one button to control the Play operation on all these devices, you only need to learn the button once and then link it to each of the three screens.

(39)

Section 4 Programming the IRIS 31

Step 4 – ‘Learning’ Commands with the IRIS

Preparing to Learn

To ‘learn’ infrared commands and link them to SCR functions, you use the DX Hand-Held Programmer.

1. Plug the HHP into the programming socket on the SCR. The main menu is displayed.

Enter Code Number or Select with SCR IRIS xx yyyyy

LEARN TYPE +10 +1

where:

xx is a number 1–80 indicating the currently selected IRIS slot number.

yyyyy is a word indicating whether the slot is in use:

EMPTY means the slot has no code stored in it. This slot is available for storing a new command.

CUSTOM means the slot contains a previously learnt code. Unless the code is no longer used, this slot is not available for storing a new command.

(40)

Press TYPE to select either IRIS or GEWA. Select IRIS if you are learning the infrared code of an appliance such as a television. Choose GEWA if you are linking to the code of a GewaLink device.

Press the +1 and +10 buttons to scroll through and check the status of the slots in the IRIS filing cabinet, either slot by slot or in steps of 10, respectively.

The Learning Process

Before you start the learning process, we recommend that you turn off the appliance so it cannot respond to the remote control during the learning process.

To learn commands, follow these steps:

1. Use the +10 and +1 buttons to scroll through the code slots until you find an empty slot. (Note: The IRIS normally shows the first empty slot automatically.)

Enter Code Number or Select with SCR IRIS xx EMPTY

LEARN TYPE +10 +1

2. Press the LEARN button to begin the learning process. A screen similar to this one is displayed.

Learn Code xx Single

EXIT NEXT ALIGN SWAP

Using the buttons on this screen you can make two types of settings:

SWAP Pressing this button toggles the selected slot between these two choices:

Single sets the slot to store a single code.

Dual sets the slot to store two codes that will be transmitted one after the other. This feature is useful for creating macro commands, such as “turn on the power and play”, rather than requiring the user to perform the two actions, “turn on the power” and “play”, individually.

This feature is also useful for some home automation devices, where two codes are necessary to execute each command. The first code selects the device, the second tells it what to do.

ALIGN This feature helps you find the optimum position in which to hold the remote control during the learning process. If you are learning several functions for a particular remote control, you only need to align the remote control for the first function you learn.

(41)

Section 4 Programming the IRIS 33 To align the remote control:

a. Press the ALIGN button.

Learn Code xx Align Transmitter

b. Point the remote control at the side face of the IRIS (toward the status light) and press any button.

If the IRIS is receiving commands from the remote control, a second LED, the activity light, will flash for as long as the button is pressed.

The HHP display will change from ‘No signal’ to ‘Receiving’:

Learn Code xx Align Transmitter

Some older generation remote controls send weak signals, and you might have to hold them within a few centimetres of the IRIS. On the other hand, some remote controls send extremely strong signals that overload the IRIS and they must be held further back.

The Align process helps you locate the optimum position (distance and angle) for teaching commands with each remote control.

c. Press EXIT to leave the Align option and return to the Learn Code screen.

4. Hold the remote control in the optimum position determined during the Align process. Press and hold down the button on the remote control that corresponds to the function you want to learn until the activity light goes out. The HHP display will also tell you when to release the button.

Learn Code xx Release Function

EXIT

NOTE It can take several seconds for the IRIS to recognise and store a command.

If the IRIS fails to learn the code, or if there is no signal it can learn, it will time out. You can either try again to learn the code or EXIT. Upon exiting, the learn sequence is aborted and the slot is erased (set to EMPTY). If the empty slot was previously linked to an SCR function screen, the HHP will ask if you want to erase existing links.

5. Remove your finger from the button.

6. You will be asked to repeat Step 4 to confirm that the command has been

recognised and stored properly. The HHP will then display confirmation that the code has been learned correctly.

Learn Code xx Function Learnt OK NEXT

The code has now been stored into the selected slot and the slot is now a

‘custom’ slot. The code will remain stored in the slot until it is overwritten by another code through the learning process.

7. For Dual codes, you now must repeat the learning process for the second command.

Step 5 – Testing and Tuning IRIS Commands

The previous section showed you how to take the IRIS through the learning process and to confirm that the IRIS has learned a command correctly. Now you must check that the appliance is correctly receiving the code when transmitted by the IRIS, and performing the intended function. This process is called ‘testing and tuning’.

NOTE It is important that the installer perform the testing and tuning process to ensure that the IRIS functions are operating correctly.

This is the first opportunity in the installation procedure to perform testing and tuning.

In some situations, it may be more convenient to perform Step 6 – Linking IRIS Commands before Step 5.

Begin this process at the Learn Code screen on the HHP with the function successfully learned.

Learn Code xx Function Learnt OK NEXT 1. Press the NEXT button to display this screen.

IRIS xx Press NEXT to Link or Edit

LEARN TEST TUNE NEXT

2. Position the IRIS where it can transmit to the target appliance, and press the TEST button. Each time you press TEST, the IRIS transmits the newly learnt code. Keep pressing TEST until you are sure that the command works consistently.

3. If the command does not work, or does not work consistently, press TUNE to access the tuning screen. Here you can set the number of times the IRIS sends the code when the user requests the command associated with it.

IRIS xx Transmit Length

nn Bursts

EXIT TEST UP DOWN

4. Use the UP and DOWN buttons to set the transmission length from 2 to 7 bursts, or to transmit continuously.

If you select ‘Continuously’, the IRIS sends the code for as long as the user operates the command. This setting is ideal for commands like Volume Up or Down. For ‘toggle’ commands such as Power On/Off, a short burst is preferable, so that the appliance does not read the command more than once.

Section 4 Programming the IRIS 37 5. Press TEST to return to the testing screen, and test the command again to

ensure that it is working properly and consistently.

6. When tuning is complete, press EXIT to return to this screen.

Example: Testing and Tuning an IRIS Command

IRIS 3 Press NEXT to Link or Edit

Suppose you now want to test and tune the stereo’s Volume Down command, which is stored in IRIS slot 3. Beginning with the IRIS Link and Edit screen, perform these steps.

IRIS 3 Transmit Length

Continuously

EXIT TEST UP DOWN

1. Since the Volume Down function is best operated for as long as the user operates the control, press the TUNE button, then press the UP or DOWN button to set the transmission length to

‘Continuously’.

2. With the IRIS in a position where it can transmit to the stereo, press the TEST button and make sure the Volume Down function operates the stereo correctly.

3. Press EXIT to complete testing and tuning.

(46)

Step 6 – Linking IRIS Commands

Now that the code has been successfully learned, tested and tuned, you need to link it to the associated SCR menu screen.

NOTE Careful planning of the SCR menu structure in the beginning prevents wasted time here. If changes are made to the menu structure after linking, some or all of the links will be ‘out of sequence’. Ensure that you record the learnt functions against each slot number in the reference lists provided so that codes can easily be re-linked to the correct SCR function screen.

Begin the linking process from this screen on the HHP:

1. Press NEXT to enter Link mode.

IRIS xx Select SCR Function

to be Linked

EXIT

2. The IRIS now waits for you to select the SCR function you want to link to the code in IRIS slot xx. Use the input device to navigate through the SCR menus until the screen that includes the command you want to associate with the code is displayed.

3. Use the input device to select the particular command on the SCR screen.

4. The infrared code located in IRIS slot xx is now linked to the command, and the confirmation screen is displayed.

(47)

Section 4 Programming the IRIS 39 Example: Linking an IRIS Command

IRIS 3 Press NEXT to Link or Edit

Suppose you want to link IRIS slot 3 to the SCR function screen called Stereo Volume. To do this, begin at this screen.

1. Press the NEXT button to enter Link mode.

2. You want to link the Volume Down command to IRIS code 3, so use the input device to move to the Volume Up/Down screen on the SCR.

3. Use the input device to select the Volume Down command (that is, give a Reverse command).

IRIS 3 Successfully Linked to SCR Function xx EXIT

4. The infrared code located in IRIS slot 3 is now linked to the Stereo Volume screen on the SCR. The HHP displays the confirmation screen.

5. To make the Volume screen fully functional, you must use the same procedure to link the Volume Up command to another empty IRIS slot.

Section 5 Maintenance 41

5 Maintenance

In the previous sections, you learned how to put codes into slots in the IRIS filing cabinet and how to associate them one by one with the appropriate screens in the SCR menu structure. This method is the most efficient way to set up an IRIS system initially, but once the system is up and running, it is easier to relearn or redefine a particular function using the approach described in this section.

Reviewing and Relearning Infrared Codes

To review and relearn existing infrared codes, follow these steps.

1. Plug the HHP into the programming socket on the SCR and move to the IRIS entry screen, as described in “Preparing to Learn” under “Step 4 – ‘Learning’

Commands with the IRIS”.

Enter Code Number or Select with SCR IRIS xx EMPTY

LEARN TYPE +10 +1

2. Using the input device, navigate through the SCR menu structure until the screen containing the function you want to relearn or tune is displayed.

3. Use the input device to select the function you want to relearn. The HHP screen displays the IRIS slot currently linked to that function.

4. Relearn this slot as described in “The Learning Process” under “Step 4 –

‘Learning’ Commands with the IRIS”.

5. Test and tune the command, as needed.

6. The slot is already linked to an SCR screen. However, if you want to change the link or link the slot to another screen, do so now.

(50)

Example: Checking the IRIS Slot Number of a Command

Suppose you want to check the IRIS slot number of the Volume Down command.

Enter Code Number or Select with SCR IRIS 56 EMPTY

NEXT TYPE +10 +1

1. Start at the IRIS entry screen, for example:

2. Use the input device to navigate through the SCR menus to the Stereo–Volume screen.

3. Use the input device to select the Volume Down command (that is, give a Reverse command).

Enter Code Number or Select with SCR IRIS 3 CUSTOM

LEARN TYPE +10 +1

4. The HHP displays ‘IRIS 3’, the number of the slot where the Volume Down command was originally stored.

IRIS Code Reference List

Use these IRIS and Gewa reference list forms to record details of the commands that are programmed into the IRIS. If an appliance is replaced, the codes for the old appliance can be quickly and easily replaced with codes for the new appliance. If you maintain more than one IRIS, you might want to make extra copies of this form for each unit.

Section 6 Controlling a Computer Mouse 45

6 Controlling a Computer Mouse

In the previous section you set up a computer submode on the SCR menu structure and configured it to control a mouse. Now you must set up how the IRIS transmits the commands from the input device to the PCMR or Gewa infrared receiver.

You can use either the HHP or Wizard to perform these settings. As a general rule, you might use the Wizard during the planning part of the installation to make approximate settings, then use the HHP on-site to make adjustments.

Setting Mouse Control With the HHP

1. Plug the HHP into the programming socket of the SCR and press NEXT until you see the DX Mouse menu.

DX MOUSE View or Edit

YES NEXT 2. Press YES to enter the DX Mouse programming mode.

DX MOUSE Dynamic Proportional

EXIT NEXT MODE ID

3. Press the NEXT button to scroll through the programming options.

Within each screen, the second and third lines show the name of the programming option and its current setting.

4. The fourth line of the display shows up to four button labels for setting the function of each programming option. Press the buttons to modify the value of each option, as needed.

Depending on the setting of certain mouse adjustables, such as Dual versus Proportional, other adjustables will not appear in the available selection of options.

(54)

Setting Mouse Control With the Wizard

1. Open an IRIS wheelchair program and double-click PC-Mouse Control on the Program Modules list.

2. A list of available mouse adjustables and their current settings is displayed.

(55)

Section 6 Controlling a Computer Mouse 47

About the Mouse Control Adjustables

The PC Mouse Control screen allows you to set four types of mouse adjustables:

General mouse settings define basic parameters about how the mouse is controlled.

Proportional settings define how the mouse reacts to commands when Proportional mode is set, while dual speed settings define how the mouse reacts to commands when Dual Speed mode is set. Directional settings define the orientation of the joystick or input device.

This table shows the adjustables that can be set using the Wizard and the HHP, and the values each adjustable can take on. The letter of each item corresponds to a line on the Wizard’s PC Mouse Control screen, as shown in the figure following the table.

General Settings

A – Mouse Receiver Type.

Set the mouse receiver type to ‘Dynamic’ if you want the IRIS to control the mouse cursor on a PC computer connected to the DX-PCMR. Set it to ‘GEWA’ to control the mouse cursor on a PC or Macintosh computer connected to Gewa’s Access USB receiver.

B – Mouse ID.

This adjustable prevents active interference from stray signals transmitted by other IRISes operating nearby, as in a classroom environment, and also prevents other IRIS users from accessing the PC. The ID number for the IRIS must match the ID number set on the mouse receiver(s) it is controlling. Nevertheless, care must be taken to ensure that transmissions from one IRIS do not disrupt signals intended for a mouse receiver other than the one it is matched with. Refer to “Setting the PCMR ID Number” in Section 7 for more information.

Both the IRIS and the PCMR can be set to one of eight ID numbers, 0–7. The Gewa Access USB receiver can be set to one of sixteen ID numbers, 0–9, A–F, of which the IRIS can match the first eight.

Refer to “Setting the PCMR ID Number” in Section 7 for information about how to set the ID number on a PCMR. Refer to the documentation that came with your Gewa Access USB receiver for information on how to set the corresponding number on this mouse receiver.

NOTE The PCMR and the Gewa Access USB receivers differ slightly. When set to ID 0, both receive from an IRIS with any ID number. However, if the IRIS is set to ID 0, the Gewa receiver must also be set to ID 0 to receive the signal, but a PCMR set to any ID number will receive the signal. See “Setting the PCMR ID Number” in Section 7 for more information.
