CommFront offers
a range of high-quality, industrial-grade, port or
externally-powered RS232 to RS485 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 RS485
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 RS485 converters provide
simple and effective ways to protect your devices from such
potential harms. |

The CVT-485-1 is
an industrial grade (wide temperature range
with surge & static protection) port-powered bi-directional
RS232 to RS485
converter,
which can be used to convert any standard RS-232C port into
a 2-wire half-duplex RS485 port and vice versa.
The unit is powered from the RS232
data line, it also supports data direction auto-turnaround,
therefore, no external power or flow control is required.
