Hi guys,
I picked up a serial 15" Elo and I don't have the mfg whip to convert from the board pinout to db9... so I figured I'll just pick up a 5x2 IDC and and DB9 shell, then just wire it myself. I think I'm over-analyzing the problem though.
I found a good site describing the RS323 pinout for DB9 at zytrax.com. If I use that along with the Elo serial controller pinout, I should be able to ignore the N/C and Key pin positions, giving me a nice 8 pin setup that I can run over cat5. I *think* all I have to do is invert the Tx and Rx on one end of my cable - and possible the CTS/RTS if it needs flow control (which seems unlikely) - and then it would work.
One of these days I am going to have to sit down with a dummies book for rs232 comms.
Am I on the right track or did I complicate the situation?
Thanks,
Shane
