SD Series
Master Station (Access Point) and
Repeater Station
Mission-critical applications demand that no single point of failure can
stop the communications system. In wireless applications the Master
Station serves as the central hub to all remote radios. Installation of
an SD adapter to an existing x790 Master Station adds direct Ethernet
connectivity to an IP network, and adds advanced data encryption. The
SDA Master Station with redundancy option increases the availability
of a system with a warm-standby configuration. The standby radio
activates automatically whenever a fault condition is detected by the
active radio.
When used as a repeater station, the full-duplex capability of the x790
maximizes the speed of data traffic retransmissions, resulting in better
system performance.

Increased Reliability
The SD Series software-defined architecture maximizes durability.
A single-board design and extended temperature range maximizes
reliability and performance in the field. A wireless system built with
SD digital radios will provide greater longevity and less maintenance
issues over the lifetime of the system.
Narrowbanding
The SD Series achieves optimal throughput with configuration options
for 6.25 kHz, 12.5 kHz, or 25 kHz, all on a single hardware platform.
The ability to operate in 6.25 kHz channels is important preparation
for the FCC mandate to use radio frequency between 150 and 512
MHz more efficiently starting in 2013. This process is also referred to
as refarming.
SD Series Remote
The SD4 radio operates in the 400 MHz frequency band and the SD9
operates in the 900 MHz frequency band. Choose between remote
models that support both Ethernet and serial, or only serial interface.
The SD Series handles concurrent Ethernet and serial traffic from
multiple sources. Directly communicate to multiple PLCs using the
built-in serial device server and modem-sharing device using industry-
standard TCP or UDP protocols.
Every SD Series wireless device includes remote management
capability and can be managed by MDS NETview or MDS InSite
management systems.
An SD Series remote radio can be used as a master.
