FEATURES
• Operates full-duplex over four wires.
• Transparent to data format and data
rates up to 64 kbps.
• Perfect for point-to-point and multipoint
applications.
• Daisychain up to 64 converters in
multipoint applications.
• Standalone version available for 115-
or 230-VAC power.
• Rackmount card also available.
OVERVIEW
The RS-232↔RS-422/485 (Data Only) Converter operates
in full-duplex mode over 4-wire lines, and it’s transparent to
data format and data rates up to 64 kbps.
A 4-position terminal block on the RS-422/485 port makes
installation a breeze. And this converter is flexible, too—it can
work in either point-to-point or multipoint applications.
You can set the RS-232 interface as either Data Terminal
Equipment (DTE) or Data Communications Equipment (DCE)
for a wide range of applications.
The RS-232↔RS-422/485 (Data Only) Converter is available
either as a standalone unit or rack card. Choose your
standalone unit for 115- or 230-VAC power.
You can transmit data up to 4000 feet (1219.2 m) over the
RS-422/485 interface. And in a multipoint application, up to
64 converters can be daisychained.
