RS-232 to RS-423 Converter
Model 423COR
The RS-232 to RS-423 converter converts unbalanced RS-232 signals to
unbalanced RS-423 signals. The RS-423 Standard uses a data line with a ground return
for each channel. The RS-423 Standard uses an unbalanced voltage digital interface to
allow communication. Ten receivers can be connected to any one driver for use in
multidrop systems. Below are two possible interconnections for connecting two RS-423
devices for maximum distance.
Risetime control for the 423COR is accomplished by using an external resistor on the 423 driver to provide
adjustable risetime of the data signals. This resistor has been selected to minimize crosswalk and maximize cable lengths
at data rates of 19.2k baud and lower. The suggested maximum cable cable length under this condition is 400 meters
(1300ft.). If this converter is to be used for higher baud rates or for very very low baud rates, the risetime resistor can be
changed. Please contact B & B's Technical Support for suggestions or modification of the converter.
