26.15.2 InterpretingDataintheGPSStatusPage(AP,BHM)
The GPS Status tab is only displayed when the Sync Input is set to Sync to Received
Signal (Timing Port), which is the configuration desired when connecting an AP or BHM
to a CMM2. See Sync Input on Page 239.
The page displays information similar to that available on the web pages of a CMM3,
including Pulse Status, GPS Time and Date, Satellites Tracked, Available Satellites,
Height, Lattitude and Longitude. This page also displays the state of the antenna in the
Antenna Connection field as
•
Unknown—Shown for early CMM2s.
•
OK—Shown for later CMM2s where no problem is detected in the signal.
•
Overcurrent—Indicates a coax cable or connector problem.
•
Undercurrent—Indicates a coax cable or connector problem.
IMPORTANT!
If Unknown is displayed where a later CMM2 is deployed, then the connection is
not working but the reason is unknown.
This information may be helpful in a decision of whether to climb a tower to diagnose a
perceived antenna problem.
