Default I/O Configuration
While the controller can be configured so that practically any Digital, Analog or RC pin can
be used for any pur pose, the controller’s factory default configuration provides an assign-
ment that is suitable for most applications. Figure 7, below, shows how to wire the con-
troller 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 com-
mand signal in the following order: 1-RS232, 2-RC Pulse, 3-None. If needed, use the Robo-
run+ PC Utility to change the pin assignments and the command prior ity order.
