Controller Mounting

During motor operation, the controller will generate heat that must be evacuated. The published amps rating can

only be fully achieved if adequate cooling is provided. Mount the controller so that the bottom plate makes con-

tact with a metallic surface (chassis, cabinet) to conduct the heat.

Sensor and Commands Connection

Connection to RC Radio, Microcomputer, Joystick and other low current sensors and actuators is done via the 15

connector located in front of the board. The functions of many pins vary depending on user configuration. Pin

assignment is found in the table below.

Default I/O Configuration

The controller can be configured so that practically any Digital, Analog and RC pin can be used for any purpose.

The controller’s factory default configuration provides an assignment that is suitable for most applications. The

figure below shows how to wire the controller to two analog potentiometers, an RC radio, and the RS232 port. It

also shows how to connect the two outputs to motor brake solenoids. You may omit any connection that is not

required in your application. The controller automatically arbitrates the command priorities depending on the pres-
