Use this pin configuration to make your own rj-11 6 pin to db9 cable
DB9 | RJ-11 6 pin |
2 | 3 |
3 | 6 |
5 | 5 |
if you wire it wrong aka flip the pin numbers on rj-11 the ultimeter 2100 lcd display is going to fade, and serial out put stops, to fix, remove power and backup battery and sett up ultimeter 2100 agene. The ultimeter serial port survives… Iv tested
