    Default TP8100 Program cable pinout

    Well I have searched far and wide for the pinout and all I have tried, fail.
    What I have done is find an old RSM and use the connector and tail as my "lead".
    I have then connected it up to a DB9 using R1->C5, R5->C2 and R6->C3.
    With no luck.
    I then paired it up with my official T2000 lead with the MAX chip in it and again no luck.
    THe issue is the software cant even see the radio to be able to even give me a DB or version error.

    Any ideas would be most welcome, excluding go buy a cable :-P

    Perhaps the thread at will help.

    If not, try an Advanced SEARCH of the forum. There are many TP8100 threads.

    Pin 1 is Data out of the radio. Pin 9 is Data into the radio. Pin 5 is common ground.

    The T2000 programming lead should work on a TP8100 but it does need external power - for a T2000 it will normally be getting this from the radio through one the wires on the RJ-12. Power does not come from the RS-232 port. For the TP8100 you can wire up either the TP8100 power output or wire up a 9V battery to the 5V regulator (78L05) inside the T2000 programmer.

    It's been a while but from memory the Tait radios run with a non-inverting level converter but if you use an RS-232 converter chip (eg MAX232) using only one pair of transceivers it won't work as the symbols get reversed by the RS-232 chip. You can get around this by using two transceivers in the chip for each direction. For example R1in > R1out > T1in > T1out. This will effectively make a non-inverting level shifter. This is what is inside the T2000 programmer. Hope this helps!
