"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

|
|
|
"The built-in 120 Ohm
terminator helps us to build a reliable
data comm. system, thanks for saving our valuable engineering
time."

Industrial RS232 to RS485 Converters
|
|
|
|
CommFront offers a
range of
rugged,
industrial-grade, easy-to-use, standard (non-isolated) or
opto-isolated, port or externally-powered RS232 to RS485
converters. These industry-proven RS232 to RS485
converter 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 RS232 to RS485 converter products provide
safe, reliable, simple, and cost-effective solutions for
your data-conversion 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 to RS485 converter
products provide
simple and effective ways to protect your devices from such
potential harms.

9-Pin RS232 to 2-wire RS485 / Fast Installation!
The CVT-485A-1 is
another version of our popular model
CVT-485-1. It is a slim, rugged, industrial-grade, port-powered, bi-directional
RS232 to RS485
converter,
which can be used to convert any standard RS-232C port into
a two-wire balanced half-duplex RS485 port and vice versa.
The unit comes with a 5-way terminal block which can be
attached to the converter securely without using screws and
nuts, and the new optional 120-Ohm end-of-line terminator design
makes the termination easier than ever before, thus making the unit an ideal
solution for quick installation and space-restricted
applications.

The CVT-485-1 is
a compact, rugged, industrial-grade, port-powered, bi-directional
RS232 to RS485
converter,
which can be used to convert any standard RS-232C port into
a two-wire balanced half-duplex RS485 port and vice versa.
The unit is powered from the RS232
data line; it also supports data direction auto-turnaround,
which automatically enables the RS485 transceiver when data
is present on the RS232 side.
Therefore, no external power, software drivers or flow
control is required.
The built-in 120-Ohm
terminator can be turned ON or OFF through a simple jumper
setting, thus making the unit an ideal solution for all
types of
mission-critical applications.
