High-Speed
Spread Spectrum
Ethernet Radio
Modem Family
The SEM910 family of products are high speed/long range wireless networking products from Murata. Operating in the license-free 900MHz
band, the SEM-series is designed to provide high-speed wireless connectivity between Ethernet devices over 20+ mile distances. Typical uses
include Ethernet bridging, SCADA networks, PLC networking, and other industrial automation or data collection applications.
SEM910D
Rail Mount
The SEM910D/X offers a DIN-rail mount
version, making connection to PLCs or
other automation devices a snap. The entire
SEM910 product family is Class I Division 2
certified, allowing deployment in hazardous
locations.
SEM910X/DX
NEMA 4X Remote Assembly
The SEM910X/DX puts the radio in a NEMA
4X remote assembly that can be located up
to 300 feet from the Ethernet connection.
This allows optimal radio placement without
the need for long RF cable runs.
SEM910 HL
Hazardous Location, Class I Div I
SEM910 HL (hazardous location) products
are ready to be deployed in hazardous
locations. These Class I Div I rated
solutions are idela for oil and gas
applications. The only access hole that
comes on the box is the antenna
connection on top. The customer then
chooses where to drill for power, data and/
or control conduit access to maximize
installation flexibility.
The SEM 910HL products can function as
high speed bridge between two 10/
100BaseT Ethernet networks or provide
wireless connectivity between an Ethernet
master bridge and multiple Ethernet remote
bridges.
The SEM910 HL provides 20+ mile range
with omni antennas. SEM products ensure
errorless data via CRC error checking and
ARQ (automatic retransmission of errored
packets).

SEM910 products use the Murata third generation proprietary frequency hopping technology. Major industrial powerhouses such as Group
Schneider, Siemens, and GE have learned they can depend on Murata products for their customers. SEM products offer extraordinary data
throughput combined with outstanding range, coverage, and link reliability. The SEM products operate easily in extended range applications, more
than 20+ miles with omni-directional antennas.
For example, the SEM can function as a high speed bridge between two 10/100BaseT Ethernet networks (see figure 1 below). SEM products can
also provide wireless connectivity between an Ethernet base station and multiple Ethernet remote modems (see figure 2). Highly complex
networks can be achieved using repeaters to extend range and coverage. The SEM910 products offer 150 Kbps data throughput, either point-topoint or multi-point. SEM910 products ensure errorless data via CRC error checking and ARQ (automatic retransmission of errored packets).
