Programming Cable

Thanks, for the suggestion, Randall. I do have the use they give for the pins--which is pretty standard, using 5 of the nine (TX, RX, RTS, CTS, SG). I figured that I would try the two combo's you suggested, using a cable I already have and a null-modem if that didn't work. Hoping someone has the actual pinout.

Thanks! I'm saving the references and will see what the bosses want to do. --John M.

Certainly smells like a bog standard RS232 cable.

You'll be using a PC with a serial port right?

Yes, the company's laptop I use has an RS232 serial port.

Then it's an RS232 cable.

Of course there's nothing to prevent Omron from having a proprietary pin out on their end... They wouldn't do that would they?

One of their books did give the use for each pin, and my memory says this was a typical use instead of something unique. Proprietary pin outs used to be fairly common early in the era, but I have not seen very many in the last decade or so.
