    You should have got one with your V2. It would be easier (and cheaper) to order one through one of our resellers, we don't try to make money on spare cables, it more to cover costs and provide a replacement service.

    Cable wiring diagram (for LC-1): FlashScan-to-LC-1-Serial-Cable-Diagram

    Your V2 came with a DB9 serial cable...
    Your wideband came with a DB9 serial cable...
    You need a null-modem adapter (orange item in pic below)... [it has to be a null-modem adapter and not just a gender bender].


    To enable serial AFR in the V2, see here: Tutorial-FlashScan-V2-Serial-Wideband-Logging


    You also have to remember to plug the null terminator plug (blank 2.5mm stereo plug) into the LC-1's SERIAL IN cable.


    This is the null-modem adapter: http://www.sfcable.com/cable/p/30D1-C1-S.html <-- less than $5 shipped

    If you can identify Tx, Rx, Gnd, then you wire them as shown in post #6 and you don't need the null-modem adapter.

    If it doesn't work, swap Tx and Rx.

    The AFM1500 pins are as noted;

    pin #1= Rx
    pin #2=Tx
    pin #3=Grnd

    According to the AFM1500 manual;

    DB9 Female (to PC)
    Terminal Number
    #2 (Rx) to pin #1 of module (male)
    #3 (Tx) to pin #2 of module (male)
    #5 (Gnd) to pin #6 of module (male)


    I assume "to module" is the AFM1500 box and the "to PC" is the feed heading to the V2??

    Trying to reason through the null modem conversion. Ughh!
