MDS 05-4670A01, Rev. E
2.0 PRODUCT DESCRIPTION
The SD Transceiver is a software-configurable, industrial radio for use
in licensed data acquisition networks. It can be interfaced with a variety
of data control equipment including remote terminal units (RTUs), pro-
grammable logic controllers (PLCs), flow computers, and similar
devices. Data interface connections can be made for both serial
(RS-232/RS-485) and local Ethernet protocols.
The radio's x710 Mode is designed primarily for use in serial MDS x710
radio networks where a central station communicates with each remote,
one at a time, to convey data and control signals. For models operating
in this mode, the radio offers direct, drop-in compatibility with existing,
older x710 networks while providing additional functionality not found
in MDS x710 radios. An SD Transceiver in x710 mode looks like an
x710 with respect to over-the-air transmission and all serial user inter-
face commands (plus some new SD-specific commands).
The transceiver employs digital signal processing (DSP) technology and
a fully digital transmit and receive IF chain to provide robust communi-
cations even under adverse conditions. Digital signal processing also
helps eliminate the effects of component variations or temperature
swings, resulting in an optimized performance.
