T-ACC-2 cable pinout:?
The 3.5mm TIP (_KEY) on the tuner goes to pin 10 (TX-REQ) on the LINEAR receptacle.
The 3.5mm SLEEVE (GND) on the tuner goes to pin 3 (GND) on the LINEAR receptacle.?
The 3.5mm SLEEVE (_START) on the tuner is not connected,?so you will have to press the button on the tuner to start the tuning process.?
The benefit of using the control cable is the transceiver TX-REQ signal will cause the Yaesu transceiver to reduce power automatically while tuning.?
The LDG tuner manuals warn to never apply more than 10 watts while tuning, otherwise arcing of the opening inductor relay contacts will wear them out fast.?
