ART Radio Modem ART400TR-1 Ref: 104-125
The -State of the Art- ART Series was designed as a result of extensive market research. The product will therefore fit into almost any system operating on licensed, or license-exempt data and telemetry channels in the VHF, UHF or 900MHz bands. The unique feature of the ART Series is the advanced microprocessor with integrated “SoftModem” which enables all of the radio’s parameters to be controlled by software. A large flash memory and E 2 PROM enables software upgrades, code changes or bespoke client code to be programmed via the serial port or over the radio link. As a further enhancement, the ART has individual synthesisers for the receiver and transmitter to enable full duplex operation, but in the semi-duplex mode the receiver can be left on to achieve a very fast turnaround time. We offer online UK licenced exempt frequencies UHF ( 458MHz Band ) . Delivery C
