1.0 ABOUT THIS MANUAL
This manual presents installation and operating instructions of the
MDS TransNET 900™ transceiver for use by a professional installer. This
person is expected to install, operate, and perform basic system maintenance
on the described radio. Following installation, we suggest keeping this
manual near the equipment for future reference.
2.0 PRODUCT DESCRIPTION
The transceiver, shown in Figure 1 , is a spread spectrum radio designed for
license-free operation in the 900 MHz frequency band. Employing Digital
Signal Processing (DSP) technology, it is highly reliable for long-distance
communications, even in the presence of weak signals or interference.
DSP technology also makes it possible to obtain information about radio
operation and troubleshoot problems, without going to the remote radio site.
Using appropriate software at the master station, diagnostic data can be
obtained on any DSP radio in the system, even while payload data is being
transmitted. (See
“Performing Network-Wide Remote Diagnostics” on
Page 43 .)
The MDS TransNET 900 is housed in a compact and rugged die-cast
enclosure that need only be protected from direct exposure to the weather. It
contains a single printed circuit board with all necessary components for
radio operation. No jumper settings or manual adjustments are required to
configure the radio for operation.
2.1 Transceiver Features
Listed below are several key features of the MDS TransNET 900 transceiver.
These are designed to ease the installation and configuration of the radio,
while retaining the ability to make changes in the future.
• 128 frequencies over 902–928 MHz, subdivided into eight frequency
zones
• Configurable operating zones to omit frequencies with constant
interference
• 65,000 available network addresses
