T
he Industrial Modem RF115 is
designed to stand up to
electromagnetic and radio
interference, industrial motors,
and temperature extremes found
in oil and gas fields and refineries,
utility substations, manufacturing
floors, military installations—
anywhere ordinary equipment
can’t go. This wireless async
modem uses Spread-Spectrum
technology to speed your data to
its final destination—safe and
error-free. Data travels over the
license-free 902–928-MHz radio
band.
You can use two modems in a
point-to-point configuration and
receive incoming signals from a
remote control device. Or use the
modem in a polled multipoint
configuration and communicate
with multiple remote devices. The
Modem’s DB9 connector is an
RS-232 interface. Optional RS-485
Modules are also available.

Key Features
INDUSTRIAL MODEM RF115
Each Industrial Modem
includes a fixed whip antenna
with a 20-mile (32.2-km) line-of-
sight range. The modem can also
be outfitted with any of our
optional antennas. Choose from
omnidirectional or unidirectional
antennas—in a variety of cable
lengths and mounting options.
For additional security, the
modem features voltage clamps
and fuses to protect your
transmissions from electrical
surges found on power lines.
Still Compatible
If you already have an
Industrial Modem RF115, don’t
worry—the MDR100A-R4 is
compatible with older models and
antennas.
We also offer adapter cables
for attaching older Industrial
Modem RF115s to newer
antennas or attaching older
antennas to newer Industrial
Modem RF115s.
Choosing the Right Antenna for
Your Industrial Modem RF115
For ordinary line-of-sight
installations, the built-in antenna
may be all you need.
If you can’t get a direct line of
sight without separating the
modem from the antenna, choose
one of our Omnidirectional
Antennas.
If you need to transmit through
trees or non-metallic structures—
or if you want to increase signal-
to-noise ratio—choose a Yagi
(unidirectional) Antenna with
Bracket Mount.
Remember, you always need a
direct line of sight in any appli-
cation over a 0.25- to 0.5-mile (0.4-
to 0.8-km) range.
