More Information

The Nexion Mobile Data System (NMDS) is a complete high-speed mobile communication solution featuring simple integration into virtually any radio based transmission system. As a member of the NMDS family, the NX2540 is a high performance DSP based VHF/UHF radio modem supporting over the air data rates of up to 8,000 bits per second on a Narrow Band 12.5Khz channel.

Under software control, the NX2540 incorporates multiple features that can be individually tailored to meet most customer demands. Advanced features include AES data encryption, data compression, remote I/O and selective and broadcast addressing. Intelligent over the air data protocols maximise data throughput and reduce data collision.
