Connecting devices to Output C
*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:
This output can be turned On and Off using the Channel 3 Joystick when in the R/C mode.
See “Activating the Accessory Outputs” on page 83 for more information.
