RS-422 Application

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

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

point-to-point connection between a PC and a scales. The advantage of

using two TCC-100 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 big improvement compared to the

15-m distance limitation imposed by the RS-232 interface).
