The wire loop is used to bring power from the controller’s internal power supply to the optocouplers and to the RC radio. Leaving the loop untouched causes the controller to operate in non-isolated mode, with power flowing into the RC radio. The following sections show the various power and isolation modes supported by the controller.

Cabling to R/C Receiver using Full Opto-Isolation

Full opto-isolation is achieved when the radio’s power and ground are totally separated from the controller’s power and ground.

Figure 44 shows the cabling of the R/C radio to the controller when full optical isolation is required.
