RS-422/485 Pinouts
The RS-422/RS-485 port with Terminal Block
Connector is shown below. Note that some for some
RS-422/485 devices, “B” is used in place of “+”
and “A” is used in place of “-“. That is, Data(B)
Data(A) are equivalent to Data (+) and Data(-),
respectively.

Note: The RTS and CTS pins are shorted, and the
DTR, DSR, and DCD pins are shorted, so
that users do not need to worry about the
hardware flow control cable wiring
problem.
USB Power Cord
If additional external power is required, the
TCC-80I can be connected to a standard 5 to 12
VDC power supply, or the USB power cord
(CBL-USBAP-50) can be used.

TCC-80I / TCC-80I-DB9
First high-speed, isolated, self-powered RS-232 to
RS-422, 2-wire/4-wire RS-485 bi-directional
converter with 2.5 KV isolation and 15 KV ESD
protection.
Overview
The TCC-80I is the world’s first high-speed,
isolated, self-powered converter. It is powered
through the host’s RS-232 port and provides
complete signal conversion between RS-232 and
RS-422/485 devices. The TCC-80I coverts back and
forth between RS-232’s TxD and RxD lines to
either half duplex 2-wire RS-485 or the balanced
signal of full duplex 4-wire RS-422/485. In addition,
the TCC-80I provides comprehensive 15 KV ESD
protection for all serial lines. Perhaps the most
important feature is the 2.5 KV isolation designed
to prevent ground loop currents, reduce damage
caused by data loss, and prevent damage to the
communication interfaces. The TCC-80I is also
designed to provide RS-485 auto data direction
control, in which the RS-485 driver is enabled
automatically when the circuitry senses the TxD
output from the RS-232 signal. Programming effort
is not required to control the transmission direction
of the half duplex RS-485 signal.
