    It's a mini-din 8 connector. I will by one that goes straight from the WB to the scan tool. I take it your scan tool is displaying your afrs correctly and accurately.


    What is your calibration in LM programmer 1.00V_10.00afr, 2.00V-20.00afr?

    On the analogue jack for the LC1 wouldn't running both analogue 1 and 2 voltages be pointless. In the LM programmer the 1st output is for a narrow band and the second is for w/b display. Only one is required. That means only 2 wires are required the output wire and ground.

    This serial connection is not reading the analog voltages, it's reading the digital AFR from the LC-1's serial port.

    For asynchronous serial comms you need 3 wires: Tx, Rx, Gnd.

    Ive found the PLX just needs

    Signal Ground
    TX

    Because there is no handshaking and it requires no data to be sent to it.
