features and benefits
The SST-900B is a radio frequency modem with an RS-232/485 interface port and 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-900B module is a wireless module that works in a frequency range of 902-928 MHz, and includes adjustable 16 RF channels and each channel can be allocated one of sixteen group IDs.
The SST-900B can be used not only in peer-to-peer mode but also in a multi-point structure. Applications
- Half-duplex up to 115200 bps
- Internal Self-Tuner
- ISM Band 900 MHz
- Typical wireless transmission range is 700 meters (LOS)
- UI Configuration via external switch
- RS-232/485 Interface Supported
- DIN-Rail Mountable
