MODEL RS422232
Bi-Directional RS422/RS232 Converter
Figure 1 – RS422232 Converter
INTRODUCTION
RS232 is an
un-balanced
serial data format allowing for transmission lengths up to 100ft. This
distance specification limits the use of this format when used in residential and commercial
automation control system applications. RS422 is a
balanced
serial data format with a distance
specification of up to 4000ft allowing for a more flexible automation control system configurations.
Xantech’s
RS422232
Converter
is a bi-directional serial converter, converting between these two
formats, in-turn, increasing the maximum distance RS232 devices can be used in.
This product serves two main functions:
1. Convert standard Serial RS232 signals to a balanced RS422 line allowing for increased
transmission lengths in upwards of 4000ft over a single CAT5 cable.
2. Companion accessory to the SmartPad LCD™ Touch Screen Panels Serial RS422
output, allowing the SPLCD to control a multitude of RS232 devices in remote locations.
