EIA Standard RS-423 Data Transmission
RS-423 (EIA-423) is another standard used in point to point
communications. RS-423 data transmission uses an unbalanced line
driver that connects to an RS-422 type balanced line receiver. The RS-
423 line driver is unique to this system. It produces voltage similar to
RS-232 but has a slew rate control input that is used to limit rise times
and cross talk on the data lines. Typical adjustment on the slew rate
control is from 1 to 100 µs. This is done by selecting a resistor on the
wave shape control input.
