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 as shown in Figure B.1.
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 the proper selection of one
resistor on the wave shape control input.
