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. Figure 9, 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 con-
troller 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.
