Overview
Although RS-232 serial ports are found on almost every
computer, because of their slow transmission speeds, limited
range, and limited networking capabilities, they are not an
effective solution for industrial strength long distance
communications systems.
Systems based on the RS-485 standard, however, utilize
different voltage lines for the data and control signals, so they are
not subject to the RS-232 limitations.
The IC-485S / IC-485SI is a bidirectional converter that
transparently converts RS-232 signals to RS-485 signals (and
vice versa). The IC-485S / IC-485SI provides Point-to-Point;
Multidrop; and Simplex operations over distances of up to 1200
m (4000 ft.), thus permitting the creation of reliable long distance
data communications systems using standard computer
hardware.
