below describes a 2 wire cabling scheme between a port on the Blue Heat/PCI

RS-422/485, Opto, Opto RS-422/485 or Universal Blue Heat/PCI RS-422/485 adapter to a port
on the RS-422/485 peripheral.

Note:
In half-duplex mode it is assumed on the Blue Heat/PCI Opto
adapter that TxD (-) is connected to RxD (-) and TxD (+) is
connected to RxD (+) via jumpers JA7, JB7, JC7, JD7 and
JA8, JB8, JC8, JD8.

Technical Tip:
The RS-422/485 electrical interface consists of a differential
signaling scheme. You should always connect the signals with
twisted pairs.
