The Wireless Gateway (FDS-Wi) is a wireless acquisition device that helps monitor remote facilities. The FDS-Wi receives 418 and 900 MHz signals from wireless devices and relays them to Facilities Monitoring Systems as SNMP, Modbus TCP/IP, Modbus RTU, and BACnet/IP signals.
The Wireless Gateway’s 418 MHz antenna receives signals from transmitting sensors within 100 feet (30.5m) of open air space. Typical sensors transmitting 418 MHz signals include: temperature, humidity, and motion sensors, power transmitters, and dry contact, analog (0-20mA), 0-5VDC, and 0-10VDC signals.
The 900 MHz antenna receives signals through up to a quarter mile (402m) of open air space from sensors and point repeaters, which can be used to increase the distance between the Gateway and the wireless sensors.
