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.
