GATEWAY WEB INTERFACE
The gateway web interface allows to change multiple settings and to monitor signal strength.
1. CONNECT TO THE GATEWAY INTERFACE
 Force your computer IP address to the same subnet as the Gateway (ex.:
192.168.0.100) and test whether it responds to pings.
The Gateway has two IP addresses. The configurable and failsafe address
172.17.17.17.
 Connect to the web-interface at http://< IP address> (ex. : 192.168.0.112) and log into its
Monitoring and Control Portal with the username and the password provided on the
Factory Settings Report received with the delivery.

 The Network / Devices page will display the connected hardware.
The Gateway incorporates 3 ISA100.11a components namely the System Manager,
Backbone Router and Gateway. All three should be present in the Devices list.
 The paired and powered field devices should appear in that list.
2. MONITOR SIGNAL STRENGTH
After the Eagle has joined, the Gateway Backbone will start recording the received signal
strength from every device.
 Click on the Backbone’s EUI-64 address on the Network / Devices page and then on the
Neighbours Health tab. Click Refresh.
A list of Eagle Field Devices together with their signal strengths and packet transmission
statistics will be displayed. Note that the information will not be available immediately for a
newly joined device because the Eagle Field Device is designed not to transmit
unnecessarily in order to conserve maximal battery life. Therefore the Backbone requires
some time in order to build up an accurate record of the received signal strength.
A typical installation should aim to have the signal strength of all Field Devices larger
than -80dBm in order to maintain a reasonable fade margin and ensure robust
communication. The following sections provide details of how to plan an installation how to
maximize performance.
Note that the update of this information is not instantaneous and can take up to 5 minutes.
The gateway must test the connection with all the sensors.
The aim is to achieve a signal strength:
above -80 dBm and definitely not below -85 dBm.
