000207 . The HANDAR 548 Receiver operates ~~rrentlv at both 300 and 1200 baud rates. Thus, it can operate within an existing 300 baud system A!!..l! also with a mix of 1200 baud transmitters. The receiver also has an LID display to provide network sta- tus: percentages of quality, noise, and loading are displayed, which are very helpful in determining if the system is degra- ding due to too many sensors, noise, etc. . The 548 Receiver has separate receiver and decoder units so that the receiver may be located as close as possible to the antenna to reduce cable losses. The receiver is a synthesized unit operating in both VHF and UfF bands. Thus, frequencies can be easily changed, if required. · The Handar Alert Data Base Software provides. many unique and convenient features including, but not limited to: --Completely menu driven for ease-of-use. --Single word (macro) commands to save time and reduce training requirements. --Use of remote terminals to access Base Station displays and data. --Data summary reports that take averages, minimums, maximums, etc of reported data values. --Alarm messages and tones for all sensors, including low battery. Alarm log file. --Password for configuration security. --Data file size not arbitrarily limited except by available disk space. --Communications Log to monitor missing transmissions. . Environmental testing of ~~h unit shipped from HANDAR is a standard production operating test. Remote Data Transmit- ters and Repeaters are tested to operate at -200C and +500C before any un'it is shipped. . HANDAR weather sensors can be interfaced to the Alert system through use of the optional analog interface board. Up to sixteen analog sensors plus one wind speed sensor can be interfaced. HANDAR's wind speed and wind direction sensors have been tested by the United States National Weather Ser- vice's Testing and Evaluation Center in Steding, Virginia. 5
