3 Introduction to the DX Heavy Duty Joystick

The DX Heavy Duty Joystick (DX-RJM-HD) is a robust and rugged switched
joystick that has been designed for users that lack the necessary fine hand
control that is associated with standard joysticks on remote modules.

The DX-RJM-HD is a DX RJM-type Secondary Remote. A DX Secondary
Remote must be added to a DX system that has a DX Power Module and a
DX Master Remote installed. Secondary Remotes do not replace the DX
Master Remote. For more information, see chapter 6 in the DX System
Manual (GBK60348 DX System Manual Issue 1). For brevity, the DX System
Manual will be referred to as DSM throughout the rest of this manual.

Note:

The DX-RJM-HD is part of the DX System. Read the DX System Manual (DSM) before reading this
manual.

The DX-RJM-HD has eight switched driving directions as shown
in Figure 1.

Because the DX-RJM-HD is a switched device, the speed cannot be
controlled with the joystick position. Adjust the acceleration and
deceleration profile settings (see DSM section 5.3) to compensate for the
absence of proportional speed control.

The DX-RJM-HD can be used to operate lighting, seating, computer
interface and environmental control by adding the relevant DX modules.

4 Installation

Warning:

Read the DX System installation procedure (DSM section 2.1), including the general wiring
recommendations, before installing the DX-RJM-HD.

The DX-RJM-HD installation process is described in the following sections:

4.1 Mount – mount the DX-RJM-HD

4.2 Connect – connect the DX-RJM-HD to the DX system

4.3 Program – set parameters Joystick Source and RJM has Analog Joystick

4.4 Test – test the complete DX system for operation and safety.

4.1 Mount

Mount the DX-RJM-HD securely to the wheelchair, in a position that is convenient to the wheelchair
user. The selected position and orientation must give maximum mechanical and environmental
protection to the DX-RJM-HD. Avoid positions in which the remote module or its wiring can be
knocked or physically damaged. Avoid positions that are exposed to splashing and other forms of
abuse.

There is a drainage hole at the bottom of the DX-RJM-HD. Do not mount the DX-RJM-HD so that the
drainage hole is blocked.

Figure 2: Measurements at the bottom of the case

Note that the top of the case is narrower than the bottom.

Warning:

The DX-RJM-HD is not fully sealed against water ingress. Care should be taken to use the DX-RJM­HD indoors and out of contact with water and other liquids.

4.2 Connect

The DX-RJM-HD is a DX Secondary Remote. It must be installed in a DX System that already has a DX
Power Module and a DX Master Remote.

Figure 3: Con necting to the DXSystem

1. Make sure that the DX System is off.

2. Connect the DX-RJM-HD with a DX BUS cable to a DX Module. This will usually be either the DX
Power Module or the DX Master Remote, but it can be any other module with an available DX
BUS socket.

Figure 4: Con necting to the DX-RJM-HD

Note:

A DX BUS cable is not supplied with the DX-RJM-HD and must be ordered separately. The correct
length of the DX BUS cable is dependent on the position of the module to which the heavy duty
joystick is connected.

Page 8 - Installation

4.3 Program

Set parameters Joystick Source and RJM has Analog Joystick as outlined in the following sections.

Warning:

Read the programming chapter of the DSM before programming the DX-RJM-HD.

4.3.1 Set Joystick Source

Set the Joystick Source parameter (see DSM 5.3.8.7) to RJM instead of Master for each Drive Profile in
which the DX-RJM-HD will be used. For more information on programming the DX System, see DSM
chapter 7.

As a general guideline select RJM for Drive Profile 1, 2 and 3, and Master for Drive Profile 4 and 5. This
will activate use of the DX-RJM-HD in the first three Drive Profiles, and the Master Remote (usually
joystick operation) in Drive Profile 4 and 5. Drive Profile 4 and 5 can then be used either by an
attendant, or as an alternative control for the user.

Note:

If a Master Remote supports only one Drive Profile, install the DX-RJM-HD in Drive Profile 1.

4.3.2 Set RJM has Analog Joystick

Set the RJM has Analog Joystick parameter (see DSM 5.3.10.15) to 'No'.

For more information on programming the DX System see DSM chapter 7.

4.4 Test

Switch on the wheelchair with the ON/OFF button on the Master Remote. If the DX-RJM-HD is
installed correctly, its Status LED (see Figure 4) will light up. If the Status LED flashes, the module is
faulty and must be replaced.

Select each Drive Profile with the Mode button of the Master Remote. Make sure that each Drive
Profile operates with the correct control device, as programmed.

Always check the performance of the wheelchair to ensure it can be used safely. In most cases the
drive performance of the wheelchair should be slowed during initial training and use. This will give the
user time to adapt to the change. In some cases permanent changes may be necessary.

Also, check to make sure that the drive performance is satisfactory. The feel of the wheelchair can
change when using a new control.

Warning:

After the wheelchair has been configured, check to make sure that the wheelchair performs to the
specifications entered in the programming procedure. If the wheelchair does not perform to
specifications, reprogram it. Repeat this procedure until the wheelchair performs to specifications. If
the intended operation cannot be achieved, contact your service agent.
