With no power connected, on the Accessory connection in the back of the unit, which is Ground?
Sm-120 reference information states that pin 7 is ground. On my unit, on the Accessory connection in the back of the unit, pin 4 is at ground. I have programmed the Accessory for pin 4 to be COR + PL., pin 9 PTT, pin 11 Rx audio , and pin 3 Tx audio. I noticed that the information on the SM-120 web page stated, in the front, the RJ-45 pin 4 is at ground. Could someone explain, or correct the Accessory connection. Thanks, 73's, Jim Kh6jkg.
