I have a Magnum ME2012 Power inverter and out of the main logic board I have phone cable with a RJ45 female jack. in the cab of the vehicle I have a display panel with another female RJ45 jack. the phone cable connects these 2 guys together and I can set things like max amp draw, low voltage cut out etc.
On the remote controller I have only 2vdc on the VCC legs of the op-amps and micro controller. I cant seem to find anyone who knows anything about power inverters or is willing to help fix this. I picture in the phone line that there is a twisted pair for communications and a VCC positive and a ground? it makes sense from an automotive design standpoint. I am also being told that telephony does not have a "heavy lifting VCC DC in the cable and that the analog voltage rides along the twisted pair com wires" im not sure if this is true or how that would even work.
I can post photos if someone is willing to help me.
