Long Range Communications
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 and modulation option best suited to their unique
requirements. The combination of these features results in the ideal data
acquisition product for error free, long distance communication.
Exceptional Network Performance
The performance of a wireless network is more than a measurement
of speed. It also includes the efficiency of the radio system in mediating
over-the-air channel access. This is particularly important for operating IP/
Ethernet in narrow licensed channel sizes. The SD Series implements several
features designed to provide maximum performance. The SD’s Media
Access Control (MAC) is optimized to reduce Ethernet overhead and preserve
bandwidth for higher usable data speed. The IP Payload feature removes
unneeded Ethernet frames to shrink messages and improve throughput.
The SD Series automatically controls over-the-air communication between
host systems and remote devices to insure that data collisions are detected
and avoided. The result is exceptional performance for networks requiring
connections to multiple host systems, multiple device types connected
to a single remote radio, or a mix of Ethernet and serial devices. The SD
also insures maximum reliability for systems implementing unsolicited
communication and exception reporting from remote devices and RTUs,
which is particularly important for non-polled protocols such as DNP3.
Backward Compatibility
MDS SD Series radios can be directly added to existing MDS x710 and
x790 systems, providing both "drop-in" compatibility for expansions and
replacements, and adding Ethernet support. Backward compatibility
preserves your investment and allows a smooth transition from a serial
based SCADA infrastructure to IP/Ethernet without disrupting day-to-day
operations.

Low Power Consumption
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.
Simple Intuitive Configuration
Use the web based SD Device Manager for easy configuration of all SD
Series parameters including transmit and receive frequencies, channel size
and modem speed. SD Device Manager is also used to access important
performance and maintenance information.
The SD Series supports 3 Virtual Radio Channels (VRC) that allow users to
assign communication to specific serial ports or IP addresses and ports
when multiple devices or systems are connected.
SD Series configuration and maintenance can also be performed using
Telnet and HyperTerminal sessions.
SDxP Redundant/Protected Models
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
alarm conditions. Switchover also occurs when no valid packets are received
in a programmable time frame of 1 to 30 minutes, or upon loss of power to
the operating radio. An internal back-up battery is provided in AC-powered
models for continued operation during a loss of primary power.
SDA Adaptor for 4790/9790 Radios
The SDA adaptor is used with 4790 and 9790 Master Stations to add IP/
Ethernet connectivity. The SDA can be ordered with new Master Stations
or easily added to equipment already installed. Once connected to a
4790/9790, one (1) serial port and one (1) Ethernet port are available for
connection to external systems or devices.
SD Series Remote
The SD1 radio operates in the 100 MHz frequency band, SD2 operates in
the 200 MHz frequency band, SD4 operates in the 300 MHz, 400 MHz and
500 MHz frequency bands and SD9 operates in the 800 MHz and 900 MHz
frequency bands. Choose between models that support both Ethernet and
serial, or only serial interface.
The SD Series handles concurrent Ethernet and serial traffic using built-in
terminal server plus industry- standard TCP or UDP protocols.
