1.1. Product Description
The Wireless Gateway is a wireless acquisition appliance that helps monitor remote facilities.
The Wireless Gateway receives 418 and 900 MHZ signals from wireless devices and relays
them to facilities monitoring systems as SNMP, Modbus TCP/IP, Modbus RTU, BACnet/IP,
and BACnet MS/TP signals.
The Wireless Gateway’s wireless sensors can receive signals from products providing dry
contact, analog (0-20mA), 0-5VDC, or 0-10VDC signals. Commonly used sensors include,
but are not limited to, temperature/humidity, temperature, door counters, thermistors, motion
sensors, power monitors, and more.
1.2. Rear Panel Indicators
The back of the Wireless Gateway has two status indicators to show when data is being
transmitted and when data is being received through the EIA-485 port. When data is either
being transmitted or received the status lights will blink. If no information is being
communicated, the lights are off.
