1 Introduction to the DX System
The DX-system is a modular powerchair control system. This modularity makes it
possible to design a powerchair that can meet the requirements of any user requirements that can range from simple drive-only control to full environmental
control. Just add additional modules when requirements grow.
The heart of the DX System
The most basic DX control system consists of two parts:
A DX Power Module, connects to the battery and to the motors
A DX Master Remote
The Master Remote is the brain of the DX System. Every DX System must have one,
and only one. There are several different Master Remotes available to choose from:
with joystick, without joystick, chin remote, attendant remote, etc.
DX System extensions
In addition to the Power Module and the Master Remote, many other remotes and
modules are available to extend the DX System, like:
•
•
•
•
Secondary Remotes, for example: attendant remotes, sip ‘n puff, finger steering
Switch input modules
Lighting and Seating control modules
Environmental control modules
The DX System can be extended to a maximum of 16 modules.
DX System connections
All modules are connected to each other by a DX BUS cable.
Most DX Modules have two DX BUS connector sockets. That way
you can connect another DX part easily.
DX BUS is an interface (the way the modules "talk" to each other) based on the CAN
interface, which is widely used in the automotive industry. CAN is well known for its
reliability and its fault detection. DX BUS inherits this reliability, and even improves on it.
One system fits all
Start out with a simple system and add the modules you need at the time they
become available, or when the application requirements grow.

2.1 DX BUS Module connection layout
DX Modules normally have one or two DX BUS sockets for system interconnections.
Smaller DX Modules can have a fixed cable that ends in a DX BUS plug, instead of DX
sockets.
The optimum connection layout is dependent on the type of modules that are
present in the DX System. Low-current modules can be connected in series. This
provides a low-cost and simple solution.

DX modules connected in series
Because of the internal resistance of the DX BUS cable, high-current modules can
cause a voltage drop on the DX BUS when they are connected far away from the
Power Module. For this reason all high-current DX Modules (for example actuators
and lights) must be connected as close to the Power Module as possible, preferably
in parallel.

3 The DX Power Module
The DX Power Module converts the speed and direction signals generated by a DX Remote
into high current outputs. These outputs drive the motors and activate the parkbrakes.
The Power Module must be connected to:
•
•
•
•
The DX BUS
The battery
The motors
The parkbrakes
M/PB-2
Battery
DX BUS
M/PB-1
The Power Module is fully programmable for a wide range of powerchair types and user
needs.

The PMB-S has its two motor and Park Brake channels driven in parallel, for a single motor
output with twice the current of each channel of a standard Power Module. The PMB-S is
used in DX Systems with only one drive motor, such as servo steered powerchair systems.

4 The DX Master Remote
4.1 Introduction
The Master Remote is the central building block in a DX System. Every DX System must have
one, and only one Master Remote.
The DX Master Remote
•
•
•
•
Acts as the primary user interface
o Has the system on/off switch
o Reads user commands (joystick movement, button pushes, switches)
o Displays the system status to the user via the System Status LED
Controls the status of the DX System
Stores and controls up to six Drive Profiles.
Provides a DX System programming socket for the HHP or the Wizard.
The Master Remote is fully programmable to suit a wide range of powerchair types and
user needs. Correct installation and programming are essential to ensure optimum
performance and safety.
The G90 Master Remote
Most Master Remotes have their own user input device in the form of a joystick, but this is
not always the case. For example: the G91 does not have a joystick, it depends on either a
Secondary Remote or a set of switches to obtain direction and speed commands.
Most Master Remotes have their own display with battery gauge and system status
information. Some Master Remotes however, such as the chin remote and the tray remote,
do not have their own display, they only have a System Status LED.

Including the Power Module and the Master Remote, a DX System can contain up to 16 DX
compatible modules depending on the application.
Available types of DX Modules are
•
•
•
•
•
•
•
Remote Joystick Module (RJM),
o DX-RJM Secondary Remotes
o Switch modules
Attendant Control Unit (ACU), joystick with attendant switch and Speed Pot
o DX-ACU1
Actuator Remote Control (ARC), 5 channels of extend/retract switches
o DX-ARC / DX-ARC-SWB
Servo Steering Motor Modules
o DX-SLM, for steering servo motor control + lights

The DX System has the option to declare some DX Modules as safety critical. This makes
sure that the DX System will not operate when that particular module is not detected
during power-up.
Warning:
Each DX Module has its own Installation Manual that describes the
installation requirements of that particular module. If you have
purchased a specific DX Module, read and understand the installation
manual of that module before installing or using the module.

5.2 Secondary Remotes
A Secondary Remote is a secondary user input device, for example an attendant joystick.
A Secondary Remote…
• Converts user input (the joystick or the switches, depending on the type of
Secondary Remote) to speed and direction signals
• Sends the speed and direction signals to the Master Remote via the DX BUS
• Can control non-driving functions (for example actuators or environmental
controls), if the Master Remote in use supports joystick control of these functions.
To use a Secondary Remote, select it as the Joystick Source in one of the Drive Profiles.
Only one RJM-type Secondary Remote can be present in a DX System at the same time.

intended application, the installer must ensure an appropriate
bend/flex radius for the intended and foreseeable environmental

Do not extend the coils farther than 2x compressed length when the
temperature is below 10°C/50°F.
Avoid extension above 3x compressed length at all times. This may
result in permanent stretching of the coils.
2. Make sure that the spring force is not applied to the DX BUS connector.
Fasten a strain relief or cable tie on or near to the coiled section of the
cable.
