Semaphore S20 SHDSL Modem Now convert existing copper wire infrastructure into a high-speed Ethernet network when installing a new SCADA or telemetry system — even if it spans distances previously unattainable by conventional DSL technology. The Semaphore S20 SHDSL Modem extends communication speed and reach without the additional investment of installing new communications media. An alternative to wireless technology, the S20 SHDSL Modem’s unique repeater capability enables communications over existing copper wire networks spanning up to hundreds of kilometers. The modem is ideal for railway, pipeline, utility, and power transmission applications that presently employ a copper wire communications network. Semaphore’s S20 SHDSL Modem extends dual Ethernets at high speeds over copper wire pairs to allow for the connection of multiple devices using standard IP protocols. Unlike most products in this category, which inherently limit transmission distance, our S20 SHDSL Modem features a repeater mode that provides excellent reach capabilities. Configuration of the S20 is extremely simple, using a Web interface to display DSL and Ethernet port status and to configure line speeds, network address, and authentication permissions. Semaphore’s S20 uses G.SHDSL (Symmetric High-speed Digital Subscriber Line) technology for sending and receiving high-speed symmetrical data streams over a single pair of copper wires at rates between 192 kbps and 2.31 Mbps. Also known as G.991.2, G.SHDSL is an international standard for symmetric DSL developed by the ITU. G.SHDSL was developed to incorporate the features of other DSL technologies, such as ADSL and SDSL, to transport T1, E1, ISDN, ATM, and IP signals. This is the first DSL technology to be developed from the ground up as an international standard. Semaphore’s S20 SHDSL Modem features: • Two Ethernet connections, with an embedded switch, over a single copper wire pair • Two G.SHDSL modems in one package • Up to 2.31 Mbps speed with up to 17 km between nodes • Repeater function that permits repetition over hundreds of kilometers • Transparent Ethernet/IP connectivity • Support of any standard IP communications, e.g., Modbus TCP • Symmetric communication that also allows voice and video • Simple configuration via Web interface • DIN rail mounting • Rugged design for industrial applications • Operating temperature of -40° to +65°C
