SST-2450EXT is a spread spectrum radio modem with controlling an RS-232/RS-485 interface port. It is designed for data acquisition and control applications between a host and remote sensors. It is also useful for those applications where the installation of cable wire is inconvenient. The SST-2450 can be used not only in peer-to-peer mode, but also in a multi-point structure.

The SST-2450 is based on a direct sequence spread spectrum and RF technology, operating In the ISM bands with a Frequency Range of 2410.496MHz~2471.936MHz. The Channel Spacing is 4.096MHz.
