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.
