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 DINrail 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 SEM2411 HL Low Cost Hazardous Location, Class I Div I 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. 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 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. 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 pointto-point or point-to-multipoint. www.RFM.com E-mail: info@rfm.com (c)2008 by RF Monolithics, Inc. Page 1 of 3 SEM2411 - 3/15/08 SEM2411 series of products use RFM fourth generation proprietary frequency hopping technology. Major industrial powerhouses such as Group Schneider, Siemens, and GE have learned they can depend on RFM products for their customers. SEM products offer extraordinary data throughput combined with outstanding range, coverage, and link reliability. The SEM products can operate easily in extended range applications with gain antennas. The SEM2411 series can function as a high speed bridge between two 10/100BaseT Ethernet networks (see figure 1). SEM2411 series products can also provide wireless connectivity between an Ethernet base station and multiple Ethernet remote modems (see figure 2). Gain antennas can be used to extend range and coverage. The SEM2411 series products offer 1 Mbps of data throughput, either point-to-point or multi-point. SEM2411 products ensure errorless data via CRC error checking and ARQ (automatic retransmission of errored packets). Figure 1 Figure 2 www.RFM.com E-mail: info@rfm.com (c)2008 by RF Monolithics, Inc.
