I got 2 Motorola CM300 and I want to program them for our local HAM Club Repeter.
The Front panel of both CM300 are lock, can it be unlock from the key pad?
I built my own RIB Interface and try to connect it to the RJ45 pin 2 (BUS+) & 5 (GND)
and try to program it with CPS R05 but it doesn't work
I also try to program it via the read connector Pin 6 (DATA) and 7 (GND)
and it also did not work.
I also try with the RJ45 pin 6 & 8 shorted ... same result.
Please help me.
