More connections—and more
power to you.
The RS-422/RS-485 Industrial
Pocket Modem (MD3452A) also
features the basic functions of
the General-Purpose Industrial
Pocket Modem and includes
an RS-422/RS-485 port. This
additional port supports 4-wire
full-duplex communication to
RS-422 devices and party-line
operation to 2- or 4-wire RS-485
equipment.
This modem can be
connected to existing multi-drop
devices and directly to industrial
inputs and outputs.
The RS-422/RS-485 Industrial
Pocket Modem is powered
directly from a 48-VDC source.
An included CD-ROM enables
you to configure the unit.
They’re built like (think) tanks.
The rugged casing and
protected circuitry keep the
Industrial Pocket Modems
working under conditions that will
cause office-grade modems to
fail. Face it, industrial applications
are demanding. But our modems
handle temperature extremes,
power spikes, and other threats.
All in the family.
Our modems contain an
industrial version of the same
modem chip set found in PC
internal modems. They support
a full set of AT commands and
protocols, plus they are fully
compatible with Windows
®
.
The get-along gang.
These modems are compliant
with telephone systems around
the world. So why not simplify
your industrial communications
and improve your bottom line?
