*The wire colors are those used by Roboteq on our prefabricated cables. It is recom- mended you use these colors for consistency.

**These connections should only be done in RS232 mode or R/C mode with radio pow- ered from the controller. Otherwise connect to radio battery.

Connecting devices to Output C

Output C is a buffered, Open Drain MOSFET output capable of driving over 2A at up to 24V.

The diagrams on Figure 23 show how to connect a light or a relay to this output:
