1.0 ABOUT THIS MANUAL This manual presents installation and operating instructions of the MDS TransNET 900™ and MDS TransNET 2400™ transceivers for use by a professional installer. This person is expected to install, operate, and perform basic system maintenance on the described radio. Following instal- lation, we suggest keeping this manual near the equipment for future refer- ence.
This number is subject to many variations depending on what options are installed and where (country) the product is used. Contact MDS is you have questions on the meaning of the code. 2.3 Spread Spectrum Radios—...

Factors such as terrain, distance, transmitter power, receiver sensitivity, and other conditions are taken into account to predict the perfor- mance of a proposed system. Contact MDS’ Technical Services Group for more information on path study services. 3.3 A Word About Radio Interference The radio shares the frequency spectrum with other services and other Part 15 (unlicensed) devices in the USA.
3.4 Antenna & Feedline Selection Antennas The equipment can be used with a number of antennas. The exact style used depends on the physical size and layout of a system. Contact your MDS repre- sentative for specific recommendations on antenna types and hardware sources.
At Remote sites and point-to-point systems, a directional Yagi antenna (Figure 8), is generally recommended to minimize interference to and from other users. Antennas are available from a sources including MDS. Invisible place holder Figure 8. Typical Yagi Antenna mounted to a mast Feedlines The choice of feedline used with the antenna should be carefully considered.
Please consider consulting a radio system engineer or other professional for advice or ground system design. A well-designed ground system will mini- mize risk of electrical shock to personnel and the chances of equipment damage. MDS 05-2708A01, Rev. D MDS TransNET I&O Guide...

Remote Terminal Unit Simulator This command re-enables or disables the radio’s internal RTU simulator, which runs with MDS’ proprietary polling programs (poll.exe and rsim.exe).

0 and the most significant bit represents XADDR 31. The full 32-bit hex value represents the entire list of extensions with which the radio will be allowed to communicate. (Pertains to Remotes and Extensions only.) This parameter is easily programmed through the MDS TransNET Configu- ration Software’s Store-and-Forward Settings panel.
ZONE CLEAR 7.0 TROUBLESHOOTING Successful troubleshooting of an MDS transceiver system is not difficult, but requires a logical approach. It is best to begin troubleshooting at the Master station, as the rest of the system depends on the Master for polling instruc- tions and synchronization data.
ENTER Major Alarms versus Minor Alarms Major alarms report serious conditions that generally indicate a hardware failure, or other abnormal condition that will prevent (or seriously hamper) further operation of the transceiver. MDS TransNET I&O Guide MDS 05-2708A01, Rev. D...
With the exception of alarm code 00 (network address not programmed), major alarms generally indicate the need for factory repair. Contact MDS for further assistance. Minor alarms report conditions which, under most circumstances, will not prevent transceiver operation. This includes out-of-tolerance conditions, baud rate mismatches, etc.
