6. Reading mode

Figure 6-1.
The three Reading mode options allow you to determine the method by which
endpoints will be selected for interrogation:
• Lat/Lon option uses latitude and longitude coordinates of the meter’s
endpoint (along with current coordinates of the EA_Mobile/vehicle) to
determine which endpoints in the route should be within the interrogation
window at any given time. It then scans only those endpoints.
Note: If no satellites are detected, the EA_Mobile will automatically
switch to FIFO mode.
• GEO option selects any endpoints with valid Lat/Lon coordinates that are
within the interrogation window AND all endpoints without Lat/Lon
coordinates, regardless of proximity to the EA_Mobile.
Note: If no satellites are detected, the EA_Mobile will automatically
switch to FIFO mode.
• FIFO option (first-in-first-out) considers all endpoints on the route to be within
the interrogation window and will repeatedly search through the route list
looking for any unread endpoints.
