MDS SD Series - 1

Grid Solutions MDS SD Series Long Range IP/Ethernet & Serial SD1, SD2, SD4 & SD9 The MDS™ SD Series are industrial wireless solutions that provide long distance communications over licensed radio bands, allowing users to interface to both Ethernet and serial devices such PLCs, RTUs and meters with host monitoring and control systems. Industrially Hardened The SD Series is the latest generation of MDS licensed narrowband wireless devices providing exceptional communication performance and reliability to meet demands for IP/Ethernet services as well as support for multiple devices and host systems. The SD is compatible with previous generations allowing for a smooth and controlled migration for existing systems. The SD Series radios are compatible with the MDS Master Station. • CSA Class I, Div. 2 groups A,B,C,D for Hazardous Locations Key Benefits • High speed, up to 65 Kbps in 50 KHz channel in SD2 and SD9 • Operate IP/Ethernet and serial communication on a single network • Connect multiple host systems to a single Access Point radio • Connect multiple devices to a single remote radio • Implement push communication and report by exception from remote devices • Simple, intuitive web based configuration and maintenance • Easy migration path from serial to IP/Ethernet • Backward compatible with existing MDS x710 networks • Compatible with MDS Master Station Application Specific Wireless Solution Oil & Gas • Operational temperature range from –40°C to 70°C • IEEE1613*, IEC 61850-3 and EN61000 for electric substation environments Application Flexibility • Supports two serial ports and an IP/Ethernet port simultaneously • Broad coverage flexibility over distances up to 50 miles • Extend Communication paths using single radio Store and Forward • Supports Ethernet Bridging, IP to serial and serial to serial communications • Low power consumption with sleep mode for solar and battery powered applications • Fast-serial features with embedded terminal server functions for serial to IP/ Ethernet encapsulation • Remote data collection from meters and flow devices Reliable & Scalable • Monitor and transmit wellhead performance and status data collected by RTUs • Exclusive, non-shared licensed band operation • High performance Media Access Control for asynchronous polling and exception reporting • Remote control of IEDs and controllers at distribution substations • Condition monitoring for pole-top circuit breakers and capacitor banks • Collision detection and avoidance insures data arrives at destination without lost messages Water & Wastewater • High receive sensitivity for long distance communications • Monitor lift stations across multiple sites from control room • Communicate with remote PLCs controlling tank levels and water flow Heavy Industrial • Activation of perimeter gates based on detection of vehicle • Monitor and control remote pumps and compressors • Compatible with multiple industry protocols including Modbus, Modbus TCP, and DNP3 Secure • AES 128-bit data encryption • Password protected access • VLAN data segregation * Requires an extern

MDS SD Series - 2

Long Range Communications Backward Compatibility The MDS SD Series of industrial-strength radios offer secure, reliable, long distance transmission of data for your mission critical applications. The SD Series combines 5 Watt transmit power and exceptional receive sensitivity to support wide coverage areas and maximum performance when difficult terrain or obstructions such as trees and buildings limit the effectiveness of other wireless devices. The SD Series operates in the 100 MHz (SD1), 200 MHz (SD2), 400 MHz (SD4) and 900 MHz (SD9) frequencies and allows users to select the channel size...

MDS SD Series - 3

SDxP Redundant/Protected Models The SD Series low power consumption and sleep mode make it ideal for applications requiring solar power operation. The SD Series requires less energy resulting in lower costs for solar panels and batteries. The SDxP is used when applications demand no single point of failure for the communications system. The MDS SDxP incorporates two MDS SD transceivers and power supplies with automatic or manual switchover capability. On detection of a failure, the MDS SDxP switches immediately to the standby transceiver. The switchover occurs for selectable transceiver...
