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 pri-

ority order.

Enabling Analog Commands

For safety reasons, the Analog command mode is disabled by default. To enable the Analog mode, use the PC

utility and set Analog in Command Priority 2 or 3 (leave Serial as priority 1). Note that by default the additional

securities are enabled and will prevent the motor from starting unless the potentiometer is centered, or if the

voltage is below 0.25V or above 4.75V. The drawing shows suggested assignment of Pot 1 to ANA1 and Pot 2 to

ANA4. Use the PC utility to enable and assign analog inputs.

USB communication

Use USB only for conﬁguration, monitoring and troubleshooting. USB is not a reliable communication method

when used in a electrically noisy environments and communication will not always recover after it is lost without

unplugging and replugging the connector, or restarting the controller. Always prefer RS232 communication when

interfacing to a computer. USB and CAN can operate at the same time on the FIM2360. Plugging USB to a com-

puter will not disable the CAN interface.
