CommFront offers
a range of high-quality, industrial-grade, port-powered
RS232 isolators and opto-isolated RS232 to RS485 / RS422
converters. These plug-and-play 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 isolator and 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 converters and isolators provide
simple and effective ways to protect your devices from such
potential harms. |

The CVT-485-3 is
an
industrial grade (wide temperature range with surge & static
protection) optically isolated bi-directional
RS-232 to RS-485 converter, which can be used to convert any
standard RS-232C port into a two-wire half-duplex RS-485
port and vice versa.
This product features
opto-isolation circuitry, which effectively protect your
RS-232 devices from
ground
loops, transient surges and spikes.
The unit is powered from the
RS-232 data line (self-powered); it also supports data
direction auto-turnaround. Therefore, no external power or
flow control is required.

The CVT-422-3 is
an
industrial grade (wide temperature range with surge & static
protection) optically isolated bi-directional
RS232 to RS422 converter, which can be used to convert any
standard RS-232C port into a four-wire full-duplex RS-422
port and vice versa.
This product features
opto-isolation circuitry, which effectively protect your
RS-232 devices from
ground
loops, transient surges and spikes.
The unit is powered from the
RS-232 data line (self-powered); it also supports data

The CVT-232A-3 is
an industrial grade (wide temperature range with surge &
static protection) port-powered RS-232 isolator. The unit
optically
isolates three (3) RS-232 lines (TX, RX and GND), which
effectively protects your RS-232 devices from
ground
loops, transient surges and spikes.
Optical isolation also
eliminates ground loop and noise problems.
The unit is powered from the
RS-232 data line (self-powered), and therefore, no external
power or RTS, DTR is required.

The CVT-232B-3 is
an industrial grade (wide temperature range with surge &
static protection) port-powered RS-232 isolator. The unit
optically
isolates seven (7) RS-232 lines (TX,
RX, RTS, CTS, DTR, DSR and GND),
which effectively protects your RS-232 devices from
ground
loops, transient surges and spikes.
Optical isolation also
eliminates ground loop and noise problems.
The unit is powered from the RS-232 data line
(self-powered), and therefore, no external power or RTS, DTR
