    It has to say "null modem" on it...

    Or get a male-male RS232 cable and cut it in the middle so you can cross-connect Tx and Rx.

    If he doesn't have cables anymore, then buy the null modem adapter from here:

    I bought the null modem. Just waiting for it to arrive.

    Until then, what firmware & Bootlock should i have in the V2 to ensure that this functionality works?

    At last, i just received my Null Modem. Before i go ahead and try it out, i wanted to check over one last detail which is the latest or needed Bootblock & firmware to make this work.

    Now i have Bootblock version 2.06.03 & Firmware version 2.06.35.

    The reason I'm asking is that under settings, i only have COM Port set to Wide-02 in my V2 while in the instructions it shows in figure 5 Com In & Com Out and both are set to Wide-02 which i don't have in my V2.

    You maybe should install V7 and V8 from >here< and then install firmware 2.6.35 that comes with this update (the version number is the same, but the date is different).

    The V2 interface has been changed since that tutorial has been written (tutorial needs update).

    What is the difference between ACProgV2_06_35.efw vs FSProgV2_06_35.efw?

    I have FSProgV2_06_35.efw in my firmware now.

    Unbelievable... i tried everything to make the null modem to work. There is no activity between the LC1 and V2 through the serial connection.

    The analog signal is reading properly now between 0-5v. Idle shows around 2.5 which is about right. I just need help to convert the reading to AF. Can someone help me?

    Are the V2 internal settings right?
    Here's mine for the LC-1, open it with the Scan&Tune.exe
