My 2 Bobs worth. For your information
The RJ45 connector on the front panel of ZASTONE Z218 Transceiver
Pin 1 is on the left looking at the radio
Pin 5 is PTT
Pin 6 is ground
Pin 3 is mike
Audio out, I took from the external speaker.
Pin 4 is also supposed to be audio out but it didn't work for me.
Need to play with the levels. TX just enough to make the interface VOX work
RX about 20% in Windoze not enough to make too much annoyance in the
speaker.
I had it right the first time but forgot that with a CAT4 UTP cable the
white/green and white/blue pairs are reversed which just happened to be
mike and PTT hence the weird results.
