RS-422 Application

A typical RS-422 application for TCC-100 Series is depicted in the following

figure. In this scenario, two TCC-100 Series units are used to create a

point-to-point connection between a PC and Scales. The advantage of using two

TCC-100 Series units to convert from RS-232, to RS-422, and then back to

RS-232, is that the RS-422 cable connecting the two converters can be up to 1.2

km in length (this is quite an improvement compared to the 15-m distance

limitation imposed by the RS-232 interface).
