CommFront offers
a range of high-quality, industrial-grade, port or
externally-powered
RS232 Repeater / RS485 RS422 Repeater products. These plug-and-play
RS232 Repeater and RS485 / RS422 Repeater products operate within a
wide temperature range (-40ºF
to 185ºF / -40ºC to 85ºC),
feature 600W surge protection and 15kV static protection. Whether
your environment is commercial or industrial, "clean" or "noisy"*, our
RS232
Repeater and RS485 / RS422 Repeater products provide safe, easy, and cost-effective solutions for your
data-communication
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 Repeater and RS485 / RS422 Repeater
products provide
simple and effective ways to protect your devices from such
potential harms. |

The RPT-232-3 is
an
industrial
grade (wide temperature range with surge & static
protection)
optically isolated RS232 Repeater / RS232 Extender) (TX, RX,
and GND), which works in pairs to extend the full-duplex
RS-232 distance up to 1.8 miles (3 km). 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, and therefore, no external power or RTS,
DTR is required.

The RPT-485_422-2 is an
industrial
grade (wide temperature range with surge & static
protection) bi-directional
RS485
Repeater / RS422 Repeater
or RS485
to RS422 Converter, which can be used to
extend the RS-485 or RS-422 distance to up to 4000 ft
(1.2km). It can also be used to convert a two-wire RS-485
signal into a four-wire RS-422 signal, and vice versa.
This
product features data direction auto-turnaround. Therefore,
no flow control is required.

The HUB-485-4
is an industrial-grade
(wide temperature range with surge & static
protection)
optically-isolated RS-485
Hub/Splitter/Repeater, which can be used to expand RS-485
networks by splitting one RS-485 network into four, in turn
increasing the maximum number of nodes and the distance
covered by an RS-485 network.
The product features opto-isolation circuitry, which
effectively protects your RS-232/RS-485 devices from
transient surges, ground loops and spikes. Opto-isolation
also eliminates ground loop and noise problems. The unit
supports data rates up to 115,200 bps and features data
format auto-sensing and self-adjusting; therefore, no DIP
switch or jumpers are required.
