Configuration
WARNING: Disconnect all battery charging
sources while programming your DCX controller.
The controllers RS-232 serial port is referenced
to the B- battery connection.
Beware of any possible ground loop faults
between your computer and the controller
which could damage both the DCX Control-
ler and PC, or cause personal injury.
Hardware: Use a STRAIGHT-THROUGH DB-9
pin / RS-232 serial interface cable to connect the
controller to the PC. Alternatively use the pre-
ferred DB-9 pin RS-232 serial port to USB
adapter.
The DCX controller must be powered before the
ControllerPRO program will have any effect.
Before programming the DCX, READ THE
SAFETY NOTES BELOW. For bench program-
ming prior to installation, a fused 18V or higher
battery may be used to power the controller.
Connect battery negative to the B- bus bar, bat-
tery positive to pin 5+6, 9+10 (Pin 8 is blank).
If you see an error “Motor Controller is Not
Responding”, verify the controller is powered
up and the connections are inserted correctly. If
the error message continues, uninstall then
reinstall the drivers for the communications ca-
ble. If the problem persists, contact Alltrax Tech-
nical Support.
Safety Notes:
Alltrax recommends that all motor controller
applications have a fuse in the battery circuit.
Many vehicles do not have a fuse, and will
need to have one installed. The following
fuses manufactured by Bussman or Littelfuse
are acceptable: For controllers rated at 400
amps or less use ANN250. On controllers
rated at 450 amps or more use ANN400. [See
Doc100-016-A_OP-Fuse-Install-Guide.doc]
Alltrax also recommends a diode across the
coil of the solenoid if it is not already installed.
A minimum of a 100V 1A diode (a 1N4004 is
suitable) is required. See complete wiring dia-
grams for orientation.
Working on electric vehicles, sudden unex-
pected events can occur, it’s recommended
to:
• Place the drive axle on jack stands—
wheels off the floor
• When working on wiring or batteries, al-
ways remove rings and watches and use
the proper safety equipment, eye protec-
tion, and insulated tools
• Never connect a computer while the vehi-
cle is being charged
• Disconnect batteries before installing or
working on the controller

grams for other configurations and vehicles
