CommFront offers
a range of high-quality, industrial-grade, port or
externally-powered
RS232 to RS422 converters. These plug-and-play
converter products operate within a
wide temperature range (-40ºF
to 185ºF / -40ºC to 85ºC),
feature 600W surge protection and 15kV static protection,
and come with built-in 120 Ohm terminators for easy
installation. Whether your environment is commercial or
industrial, "clean" or "noisy"*, our RS232 to RS422 converter products provide safe, easy, and cost-effective
solutions for your data-conversion applications.
* A "noisy" environment
is an area
surrounded by ground loops, transient surges
and spikes, which could potentially harm your expensive
equipment such as computers and data communication
devices.
The CommFront opto-isolated RS232 to RS422 converters and isolators provide
simple and effective ways to protect your devices from such
potential harms. |

The CVT-422-1 is
an industrial grade (wide temperature range
with surge & static protection) port-powered bi-directional
RS232 to RS422
converter, which can be used to convert any standard RS-232C
port into a 4-wire full-duplex RS485 / RS422 port and vice
versa.
The unit is powered from the RS232
data line, and therefore, no external power or flow control
is required.
