GP400 Module
The GP400 Module sends, receives and processes inputs from the Motor Control and Matrix mod-
ules, then controls output function. Communication between the three modules is achieved through
the use of CAN bus communication link.
The GP400 was designed with the technician in mind. Through the use of the EZ-Cal interface tool, it
allows the technician to make adjustments to various personalities, monitor inputs and outputs in real
time, plus access informational messages for both current and recent events. A complete list of
EZ-Cal messages can be found on the following pages.
The GP400 operates on 12 volts DC and should never be probed or operated with voltage higher
than 14 volts DC.
