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.

single remote radio
• Operate serial and Ethernet devices
concurrently on the same network
• Implement exception reporting and pushed
communication initiated by remote devices.
Highest Network Performance
• SD Media Access Control reduces network
overhead, prevents data collisions and insures
successful data delivery.
• High transmit power and exceptional receiver
sensitivity maximizes performance over
significant distances and challenging terrains
Flexible System Communications
• Provides IP/Ethernet and serial communication
for multiple hosts and asynchronous polling
• Embedded terminal server functions support
serial & Ethernet connections without adaptors.
• Secure AES 128 encryption for IP/Ethernet UDP,
TCP Client and TCP Server and serial.
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.
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.
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.
