A850 Telemetry Gateway

The A850 Telemetry Gateway is the core of every Adcon monitoring network, be it a pure GSM / GPRS network, a UHF radio network or a combination of both – it’s the A850 that knows exactly when and how to retrieve data from each RTU.
  • Base Station for Adcon Wireless Sensor Networks
  • Manages up to 1000 Adcon RTUs, easy to operate via graphical user interface, integrated uninterruptible power supply (max. 5h), 1GB data memory sufficient for 200 stations for 4 weeks, embedded Linux OS
  • Connects seamlessly into Ethernet networks
  • 2x USB; 1x 100MBit Ethernet; 1x RS-232; 1x RS-485 (to A440 Wireless Modem)
