RS-422/RS-485 Pinouts
The RS-422/RS-485 port with terminal block
connector is shown below. Note that some
RS-422/485 devices "B" instead of "+" and use "A"
instead of "-". That is, Data (B) equals Data (+), and
Data (A) equals Data (-).

Serial Port Powered Media Conversion Solution
Transio TCC-80 V2.2 /
TCC-80-DB9 V1.0
Self-powered RS-232 to RS-422, 2-wire/4-wire
RS-485 bi-directional converter with 15 KV ESD
protection
Overview
The TCC-80, which is powered by the RS-232 port,
provides complete signal conversion between
RS-232 and RS-422/485 devices. The TCC-80
converts back and forth between RS-232's TxD and
RxD lines, and either half duplex RS-485 or the
balanced signal of full duplex 4-wire RS-422/485.
In addition, the TCC-80 provides comprehensive 15
KV ESD protection for all serial lines. The TCC-80
is also designed to provide RS-485 auto data
a e l
direction control, in which the RS-485 driver is
enabled automatically when the circuitry senses the
TxD output from the RS-232 signal. Programming
is not required to control the transmission direction
of the half duplex RS-485 signal.
