SST2450 RF 2.4GHz Radio Modem RS232 + RS485 ports

£271.00

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

Based on direct sequence spread spectrum and RF technology operating In ISM bands. The Frequency Range is 2410.496MHz~2471.936MHz. The Channel Spacing is 4.096MHz.
