UHF Radio Modem
CBX-450
The CBX-450 is a high-speed, car-based half-duplex radio modem suitable for a variety of data transfer applications.
A typical application includes data handshaking to ensure best possible circuit coverage with the CBX-610 telemetry system.
All parameter settings of the radio modem can be modified through the interface from a PC.
External connections for modem status and diagnostics are included.
Application
Two-way data transfer from car to garage.
