 Introduction

SST-900/SST-2400 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 application, the cable wire is inconvenient to be installed. Please refer to the right hand side hardware configuration .
