A Kenwood LMR dealer in Halifax, NS, Canada asked Datalink to supply a tracking and monitoring system for 95 School Buses. The system had to track start and stop times, scheduled en-route stops, door openings and closing. All statuses time/date stamped.
Datalink i50 data terminals were installed in each bus and wired to the required sensors. The i50s were connected by cable to the data connector on the rear of the radios. GPS location information and other data is transmitted over the Kenwood network to a base radio which is cable connected to a PC computer which runs a "serial to Ethernet" adaptor which forwards the data to a DataGate and WebGate desktop monitors.
OPTIONAL BASIC OPERTION WITH ONLY NX RADIOS
The lowest cost option is to use only NX radios with GPS. Use NX radio inputs to sense door openings and other actions. If GPS reports are sent every X minutes they may interfere with voice communications. If that is a problem, only use door opening, Ign ON/OFF reports.
