1.2 Important information
Do not install, maintain or operate this equipment without reading, understanding and following this
manual – including the Safety and Misuse Warnings – otherwise injury or damage may result. This
manual contains integration, set up, operating environment, test and maintenance information
needed in order to ensure reliable and safe use of the product.
The term ‘programming’ used in this manual refers to adjusting parameters and configuring options
to suit an application and does not change or replace any firmware within the controller.
Programming is performed using a controlled programming tool available only to authorised
personnel.
The products described in this manual are not user-serviceable. Specialised tools are necessary for the

4.1 Remote module overview
This manual describes the following DX2 compact remote modules:
l DX2-RJM — DX2 Remote Joystick Module (RJM)
l DX2-RJM-LF — DX2 RJM with low force joystick
l DX2-ACU — DX2 Attendant Control Unit (ACU)
The DX2-RJM, DX2-RJM-LF and DX2-ACU are compact remote modules that share the same form, yet
have different functions. The DX2-RJM and DX2-RJM-LF remote modules are designed for use by the
wheelchair occupant, whereas the DX2-ACU has been designed for use as an attendant controller.
All of the remote modules share the same user interface, have multiple mounting capabilities and
come with a fixed, trailing lead (DXBUS) that allows for easy integration into existing DX2 systems.
4.1.1 The DX2-RJM / DX2-RJM-LF
The DX2-RJM and DX2-RJM-LF are compact, secondary remote modules
designed to provide a simple interface for the wheelchair occupant using a
DX/DX2 system.
With a modern, low-profile design, the remote modules employ joystick
technology from the LiNX product range, and are designed to be drop-in
replacements for the DX-RJM’s. They also have several enhanced features,
including the ability to turn the system on/off and to select and operate
Figure 1: DX2-RJM and DX2RJM-LF
Low strength users will enjoy the low force joystick option with the DX2-RJM-LF, which provides
smooth control with a deflection force of just 1.1 N.
Drive and Accessory menu options.
Benefits
l Built-in power button — enables the user to easily power up or down the system
l Built-in mode button
l Simple LED indicator shows what Drive Profile is selected
l Tri-colour battery gauge
l Attendant in charge indicator
l A range of mounting orientations — standard, tray, centre-line and swing-away mounts
l Low force joystick option will improve control for those with low muscle strength

4.1.2 The DX2-ACU
The DX2-ACU, with its modern, low-profile design, is an attendant control
unit, and an ideal secondary control solution for any DX/DX2 system. It
employs joystick technology from the LiNX product range and is designed
to be a drop-in replacement for the DX-ACU’s.
The new design has several enhanced features, including a selection of
“who’s in charge” options.
Figure 2: DX2-ACU
Benefits
l Built-in power button enables the attendant to easily power up or down the system
l Mode button:
o
Short press — adjust wheelchair speed to your walking speed with digital speed control
o
Long press — easily switch control between attendant and occupant
l Range of “who’s in charge” options (first-in-first-served, attendant priority, user priority and
DX-like)
l Simple LED speed indicator showing selected speed range
l Tri-colour battery gauge
l System status and attendant in charge indication
l Control your client's comfort with the ability to select and operate actuators through the joy-
stick (with selected Master Remotes)
l Able to be mounted in a variety of orientations to suit individual chair needs
l Fully sealed case design provides improved protection against water and dust ingress

4.3 System overview
The DX2-RJM, DX2-RJM-LF and DX2-ACU operate as secondary remotes within a DX/DX2 wheelchair
control system. They connect to a master remote module via the fixed, trailing lead (DXBUS) as shown
in Figure 3: System diagram.
:
Note
Not all master remote modules are compatible with the compact remote modules - for more details, see section
4.3.2 Compatible master remote modules.
Figure 3: System diagram
4.3.1 System configurations
The DX2-RJM, DX2-RJM-LF and DX2-ACU compact remote modules can be used in the following
system configurations:
Primary Secondary Secondary
DX/DX2 Master remote DX2-ACU -
DX/DX2 Master remote DX2-RJM / DX2-RJM-LF -
DX/DX2 Master remote DX-RJM DX2-ACU
DX/DX2 Master remote DX-ACU DX2-RJM / DX2-RJM-LF
DX/DX2 Master remote DX2-ACU DX2-RJM / DX2-RJM-LF
Note that there can be only one RJM-type module in a system configuration. That is, the
configuration will support a DX2-RJM and DX2-ACU combination, or a DX2-RJM-LF and DX2-ACU
combination, but it will not support a DX2-RJM and DX2-RJM-LF combination.

:
Note
Any accessory modules, such as the DSL-105 Proximity Head Control, or DX-SNP Sip and Puff, that appear as an RJM
in a DX/DX2 system, cannot be used in combination with another RJM-type module.
4.3.2 Compatible master remote modules
The DX2-RJM, DX2-RJM-LF and DX2-ACU compact remote modules will only operate with UCM II
based master remote modules. The following master remote modules are compatible with the DX2RJM, DX2-RJM-LF and DX2-ACU compact remote modules.
DX-REM24SD DX-REM34B
DX-REMG90/A/T DX-ACU3B
DX-REMG91/S DX2-REM420/1
DX-REM48/A
(see note below)
DX2-REMA/B-ACS2 DX-REM41D/E
DX2-REM550/1
Warning
The compact remotes described in this manual are to be used with selected UCM II based master remote modules
only - see table above. DONOT use with UCM I based master remote modules.
Note
All of the master remote modules listed in the table above, with the exception of DX-REM48/A, are UCM II based.
Depending on its age, the DX-REM48/A may be a UCM I type. If you are using a DX-REM48/A, ensure that it is a
UCM II type before using in a system. If you are unsure, consult your service centre.

6.1 Mounting
There are numerous options available for mounting the compact remote module, such as:
l tray mount
l clamp mount
l base plate mount
The choice will depend on the type of compact remote (DX2-RJM/-LF or DX2-ACU) being installed and
its user (wheelchair occupant or attendant): for a wheelchair occupant, the tray, clamp and base plate
mount options may be suitable; for a wheelchair attendant, the tube or drop-in mount options may
be more suitable.
6.1.1 Cable routing options
The base of the remote module has two cable exit
recesses located on either side. These allow the bus
cable to extend from the remote at any angle between
vertical and horizontal.
For plate mounting options, this means that the cable
can be routed to the side of the remote module, and
above the plate, as shown in Figure 5.
l tube mount
l drop-in mount
Figure 5: Cable routing options
Warning
Limit to ten or fewer the number of times the compact remote module is installed on to a plate if the bus cable is
at 90° to the module; frequent flexing at this angle may damage the cable.
