High Speed

Spread Spectrum

Ethernet Radio

Modem Family

.The SEM2411 series of products are very high speed/long range wireless networking products from RFM. Operating in the globally license-free

2.4GHz band, the SEM products are designed to provide high-speed wireless connectivity between Ethernet devices. Typical uses include

Ethernet bridging, SCADA networks, PLC networking, and other industrial automation or data collection applications. There is also a low cost

version available.

SEM2411D

Rail Mount

The SEM2411/D/X offers a DIN-

rail mount version, making

connection to PLCs or other

automation devices a snap. The

entire SEM2411 product family is

Class I Division 2 certified,

allowing deployment in

hazardous locations.

SEM2411X/DX

NEMA 4X Remote

Assembly

The SEM2411/D/X 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.

SEM2411 LC

Low Cost

The SEM2411LC can be

deployed as a low cost remote

bridge using a standard

SEM2411 as the base bridge.

The SEM2411LC can function

only as a slave device and must

communicate with a standard

SEM241. A SEM2411 can

support up to 62 SEM2411LCs.

The SEM2411LC radio is

housed in a NEMA 4X remote

assembly that can be located

up to 100 feet from the Ethernet

connection. This allows optimal

radio placement without the

need for long RF cable runs.

The SEM2411LC remote radio

assembly includes an integral

6dB patch antenna, removing

the need for expensive,

external antennas.

SEM2411 HL

Hazardous Location, Class I Div I

SEM2411 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 2411 HL 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.

SEM2411 HL provides a 1,23Mbps data

rate. SEM products ensure errorless data

via CRC error checking and ARQ

(automatic retransmission of errored

packets).

The SEM2411LC offers 1 Mbps

of data throughput, either point-

to-point or point-to-multipoint.
