MODEL 8800 SERIES GEONET WIRELESS DATA HOSTING SYSTEM
| NETWORK INSTALLATION |
23
Under normal Deployment mode radio conditions, the gateway and logger units
will find each other in less than three minutes; this establishes the network.
Once the network is established and the network time is set, the gateway's
green LED will flash simultaneously with the green LEDs on the loggers. If the
network time has not been set, the gateway's red LED will blink in unison with
the loggers. In that case the time must then be set using the Agent software.
IMPORTANT:
Deployment mode will cease automatically after one hour, at
which time Normal mode will being.
If the correct lights do not illuminate, or if the network has exited Deployment
mode, press the Status button on the gateway to restart Deployment mode.
3.7.1 PLACING THE GATEWAY AND ADDING LOGGERS
Place the gateway in a location central to the distribution of the loggers, if
possible (see Figure 33 below). Doing so will minimize the number of hops,
which will improve battery life.
While in Deployment mode, loggers may be added simply by turning them on
within radio range. When adding loggers,
start with those closest to the
gateway.
Watch the LEDs while moving the loggers, to ensure the signal isn’t lost.
After 10 minutes, the LEDs on the loggers will stop indicating their status, to
conserve batteries. Pressing the Status button on a logger will reactivate the
LEDs for another 10 minutes.
By default, a network will remain in Deployment mode for one hour. When a
new logger joins the network the timer will reset, extending the deployment
period for another hour. If more time is needed while deploying loggers, the
default deployment timeout may be changed using Agent software.
If isolated from the rest of the network, a logger will continue to sample and
store data. When communication is reestablished, it will "catch up" by sending
all collected data to the gateway.

STATUS BUTTON FUNCTIONALITY
All GeoNet devices have red and green LED indicators to display their status. A
reference key is printed on the side of each unit, below the LEDs. When pressed,
the Status button triggers the appropriate LED indicators to briefly illuminate.
For networks with a Local Gateway, data will not be
collected until the network time is set. To do this, use the Agent
software. The default scan interval for data collection is 10 minutes.
