RS-422 Application
A typical RS-422 application for TCC-100/100I is depicted in the following
figure. In this scenario, two TCC-100I units are used to create a point-to-point
connection between a PC and Scales. The advantage of using two TCC-100I 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).
