Spektrum DSMX Quad Race Receiver with Diversity Pinout?

[Michael Gauthier]

I just bought a Spektrum DSMX Quad Race Receiver with Diversity for my raceflight v1 controller. Unfortunately there is no indication of the wiring pinout. The 3 wires in the connector cable are gray, black, and orange.

How do those colors map to Ground, Power, and SBUS?

DSMX Quad Race Receiver with Diversity

What is the model number (begins with "SPM") ?

 

[RENOV8R]

4648

Renov8r, you don't show a SBUS pin and my cable only has 3 pins on both ends of the cable.
This is an SPM4648

Renov8r is correct

Grey is RX signal -> S-Bus
Black is Negative -> Ground
Orange is Positive -> Power (DO NOT connect to 5V power pad)
