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

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 110 for more information.

When the controller is used in RS232 mode, this output can be turned On and Off using the !C (On) and !c (Off) command strings. See “Controller Commands and Queries” on page 128 for more information.
