"I am communicating with kWh
(energy) meters that have the RS485 built in, the
port-powered converter's auto-turnaround feature works
really well for my application, and I don't have to
change any configuration."
- Peter

CommFront offers
a range of rugged, industrial-grade, port or
externally-powered
RS232 Repeater / RS485 RS422 Repeater products. These
industry-proven RS232 Repeater and RS485 / RS422 Repeater products
are designed to
interface with mission-critical equipment, such as
computers, PLC, SCADA and HMI. Whether your environment is
in the field, server room, factory, control room, or fire
command center, "clean" or "noisy",
these popular serial repeater products provide safe,
reliable, simple, and cost-effective solutions for your
data-conversion, distance-extension and device-protection
applications. We back our
high-quality products with a 30-day risk-free money-back
guarantee and a 5-year replacement warranty.
* A "noisy" environment
is an area
surrounded by ground loops, transient surges,
remote lightning 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
a compact,
rugged, industrial-grade,
optically-isolated, port-powered 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, remote lightning and spikes.
The unit is powered from the
RS-232 data line, and therefore, no external power, software
drivers or RTS,
DTR is required.

The RPT-485_422-2 is
a compact, rugged, industrial-grade,
bi-directional
RS485 to RS422 converter
/ RS485 RS422 repeater, which can be used to convert any
standard two-wire half-duplex RS-485 port into a four-wire
full-duplex RS422 port and vice versa. It
can also be used to extend the RS-485 or RS-422 distance to
up to 4000 ft (1.2km).
The
unit is powered from an external 5VDC regulated power supply;
it
also supports data direction auto-turnaround. Therefore, it
requires no software drivers or flow control, making the
unit a highly reliable and truly plug-and-play
device
and an ideal solution for
all types of
mission-critical
applications.
A separate external 5VDC regulated power supply is included
in the package.

The
RPT-485_422-4 is a rugged, industrial-grade, optically-isolated
RS-485/RS-422 repeater/converter, which can be used to
extend the RS-485 or RS-422 distance to up to 4000 ft
(1.2km), it can also can be used to convert a two-wire
RS-485 signal into a four-wire RS-422 signal, and vice
versa. This industrial RS485 /
RS422 converter / repeater
features
opto-isolation
circuitry, which effectively protects your RS-485/RS-422
devices from ground loops, noise problems, transient surges,
remote lightning and
spikes.
The unit supports data rates up to 115.2K
Baud, and comes with the baud rate auto-sensing and
self-adjusting feature.
Therefore, it requires no DIP switch setting, software drivers
or flow control, making the unit a highly reliable
and truly plug-and-play device
and an ideal solution for all types of mission-critical
applications.

The HUB-485-4 is a rugged,
industrial-grade,
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, remote lightning 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.
Baud rates: 300 to 115.2K
Baud.
