Commands and I/O Connections

Default I/O Configuration

While the controller can be configured so that practically any Digital, Analog and RC pin can be used for any pur-

pose, 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 two outputs to motor brake solenoids and another output to an external status

LED. You may omit any connection that is not required in your application. The controller automatically arbitrates

the command priorities depending on the presence of a valid command signal in the following order: 1-RS232, 2-

RC Pulse, 3-None. If needed, use the Roborun+ PC Utility to change the pin assignments and the command prior-

ity order.
