A: Flight controllers: PIXHAWK/Mini Pix/TURBO PiX/APM
Note: Old version AT9 needs to upgrade the firmware to V1.2.6(OSD)or above while AT10II needs to upgrade to V1.0.6(OSD)or above.
A：1. With receiver (R12DS as an example): one end of the 4pin wire is to the pins on the receiver while the other end of the wire is to the balance head of the battery as the below picture shows
2. With the flight controller: one end of the wire to PRM-03 while the other is to the TELEM port on the flight controller
Mini Pix as example TURBO PIX as example
PIXHAWK as an example APM as an example
A: Capable of telemetry of flight speed, rising speed, throttle, battery voltages, longitude, latitude, GPS, signal, RSSI, flight modes, direction, roll, pitch, and distance.
A: Since ardupilot updated the firmware recently, when users use PRM-03 with RadioLink transmitters AT9S Pro, AT9S, AT9, AT10II, AT10, and the ardupilot pixhawk flight controller with the V4.1 or above firmware, only telemetry of model voltage is supported, telemetry of other OSD data is not supported. Please solve the problem by changing the value of SERIAL1-PROTOCOL and SERIAL2-PROTOCOL in Mission Planner.
CONFIG- Full Parameter Tree- search “serial”-Change the value of SERIAL1-PROTOCOL and SERIAL2-PROTOCOL to 1(MAVLink)
Note: PRM-03 produced before May 31, 2022 can refer to this method to modify the value, and those produced after May 31, 2022 do not need to modify the value.
