3.Feed the RX Receiver Unit cable through one of the glands in the base of the SR2.
4.Connect the cable to JP14 as below:
Pin 1: Unused (on left)
Pin 2: Unused
Pin 3: Yellow (RX data)
Pin 4: Red (RX power)
Pin 5: Blue (Signal Strength)
Pin 6: Unused
Pin 7: Green (GND)
Note: | Incorrect wiring can seriously damage the SR2; always double-check the wiring before connecting the power! |
