Cable for First Gen BTech 50x2


Any advice on how to piece this cable together? The first gen 50x2 has only a TS Line-Out connector in the back, and not the TRRS like the new version. It is compatible with TS Mono Speakers.

So I know I’ll need to splice a TS and RJ45 together into a TRRS for the digirig but I wasn’t 100% sure on the connections to make. The RJ45 pinout looks like this:

  1. Data Input
  3. MIC
  4. MIC Ground
  5. PTT.
  6. GND
  7. +8v DC Out
  8. Null


The connections to Digirig’s audio socket should be something like this:

RJ-45 pin 3 (MIC) → 3.5mm TRRS ring 1 (RIG_AFIN)
RJ-45 pin 5 (PTT) → 3.5mm TRRS ring 2 (RIG_PTT)
RJ-45 pin 6 (GND) → RJ-45 pin 4 (MIC Ground)
RJ-45 pin 6 (GND) → 3.5mm TRRS sleeve (GND)
3.5mm TS tip (SP) → 3.5mm TRRS tip (RIG_AFOUT)

Thank you for the reply. I gave that a try but it’s making the radio power cycle over and over. Any idea what that could indicate?

Try disconnecting:
RJ-45 pin 6 (GND) → RJ-45 pin 4 (MIC Ground)

If that doesn’t solve the problem try removing other connections one-at-a-time until radio returns to normal function.
