How to Switch Between Two Cameras on the AET-H743 Flight Controller

Configure the analog camera power supply according to the actual camera requirements. An analog camera can use 5V or 9V; cameras rated below 5W may also use 9Vsw. Connect the primary video signal to CAM1. This flight controller supports two cameras, so connect the second camera to CAM2. You can use the radio transmitter to switch the displayed video between CAM1 and CAM2. Configure the following MissionPlanner parameters:

RELAY PIN2=82

RC8 OPTION=34

The configuration above assigns channel 8 as the camera-switching channel. You may select another unused channel to match your radio transmitter configuration. For AP firmware version 4.5 or later, first configure RELAY2 FUNCTION=1, then configure the parameters above.
