With Graupner HoTT radios you can use fully digital, single-line SUMD protocol. For the connection only normal servo cable is required.
1 Wiring
Connect the cable according the photo. In the unit the cable is in the RUD port. In the receiver it is always the last channel. For GR-12/GR-12L it is output with label "6". Please note that the signal wire (Orange) is at the bottom in the receiver.
If you have not connected a power supply, you can connect the BEC cable or 1-2S LiPol now (even without a servos). Never connect a power supply to the SYS or ELE/PIT/AIL ports!
2 Spirit Settings
After initialization of the unit you can start the software. To allow the connection set the Receiver type to SRXL/SUMD in the General tab.
Now save the settings (CTRL+S) or in the Backup tab/Unit - Save.
3 Receiver configuration
By default SUMD transmission is disabled in the HoTT receivers. It is necessary to enable it in the (F) Function/Telemetry/Setting & Data View menu. Change SUMD at CH6 to YES.
