Description

MOXA TCC-80-DB9 Port-powered RS-232 to RS-422/485 converter with 15 KV serial ESD protection

Introduction

The TCC-80-DB9/80I provides complete signal conversion between RS-232 and RS-422/485, without requiring an external power source. It supports both half duplex 2-wire RS-485 and full duplex 4-wire RS-422/485, either of which can be converted between RS-232’s T x D and R x D lines. In addition, the TCC-80/80I’s 15 KV ESD protection guards against damage from electrostatic discharge. The TCC-80I is the world’s first high-speed, port-powered converter with 2.5 KV isolation.

Automatic data direction control is also provided for RS-485, in which the RS-485 driver is enabled automatically when the circuitry senses the T x D output from the RS-232 signal. This means that no programming effort is required to control the transmission direction of the RS-485 signal. Moreover, the TCC-80I patented LED port power indicator can let you check if TCC-80I is receiving enough power or not.
