I've got a rs485 device and an adapter for rs232<->rs485 and no rs485
experience, so before I solder this wire harness, I want to make sure
I'm making the right connections.
Assuming no flow control,
From the rs485 side, I need TX+,TX-,RX+,& RX-. On the 25pin D
connecter, these are pins 5,22,20,& 7 respectively.
For the rs232 side, I just need RD & TD.
Is there anything I'm missing?
Also, I tore open an old 25 pin rs485 connecter and found a few pins
that were soldered together. I can't find any pin-outs on the
connecter so I have no idea as to there function.
Thanks,
