SST-2450

SST-2450 Wireless Modem Module RS-232/RS-485 Interface

SST-2450EXT is a spread spectrum radio modem with RS-232/RS-485 interface port. It is designed for data acquisition and control application between host and remote sensors. It is also useful for those applications, the cable wire is inconvenient to be installed. 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.

Basically the SST-2450 is the same with SST-2400. The most different is the setting method. SST-2400 is set by jumper, and the SST-2450 is set by software utility. The new SST-2450 can also work together with this SST-2400 if you change the inside 8051 chip of SST-2400. Just contact us, then we will ship a new chip which is with a new firmware.
