    Default Need help identifying pinout

    I'm working on ordering (or building, depending on my options) a male DB25 to female DB25 adapter for a client. I have ordered a new cable for a duplicate machine, however upon inspection, the pinout layout is significantly different than the one I'm currently using. The pinout pattern I need to replicate is attached. I'm hoping this part exists out there, but if I have to build it myself with a kit I will. Thanks for your help in advance.

    I'm sorry but I'm having a bit of trouble understanding you're diagrams, not sure what is what. But it looks like a standard 25 pin null modem connection. Google is your friend here.

    Exactly, it is a null modem cable. Rx/Tx are swapped (pins 2 and 3), DTR loops back to DSR and CD (pins 20, 6 and 8), RTS loops back to CTS (pins 4 and 5).

    This looks alot like a fadal cnc rs232 connection . They used this pinout for their controllers before changing to fanuc
    If this is for a fadal machine..... since both ends are 25 pin the 7 pin goes straight thru if it was a 25 to 9 pin it would fo to the 5 pin check out rs232 pinout for fadal
