I really could use some help from a hardcore tech that is intimate with the internal workings of an XG-100M.
My findings starting with power:
What should be the 'OFF' state I get .9amp current. this should be 2 Ma max.
On the CAN bus, I get what looks like a clock signal from the control head. No apparent response from the MRU.
Head disconnected I get no data at all on the MRU CAN bus, no sign of any bias.
I get same results at the RS232 plug.
Mostly needed are test points on the board to find the fault.
The board has a collection of what look test points. One is 10 point (headder?) The other is 14 point. (another headder?)
See attached images.
What I need are pin assignments for these
If there are any other test points that may help locate the fault, I really could use that info also.
I really hate to think my investment is just a good control group.
Supposedly, the radio was bricked for a bad firmware, but this is beyond that.
I am really needy here can anyone please help ?
