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).
