Modem
– When Option 03 is installed, the Modem maybe used as a Primary Time Source or
Secondary (backup) Time Source to GPS for the Model 9289.
User
– The Time Source is the result of the user setting the time from the System Setup/System
Time web browser user interface page when no Time Source is present.
The
Static System Information
section of the System Status screen provides the software
revisions, the NetClock’s Serial Number, and the MAC address.
The
System Test Results
section contains the results of the internal tests that are run. These
test are not complete checks of the entire paths (For example, the Serial port may pass even
though it has been damaged by a surge).
GPS Startup Self-Test
– The GPS Startup Self-Test
will indicate the status of the antenna,
antenna cable and the GPS receiver at the time of power-up only. If the antenna cable was not
connected, shorted or open at the time of power-up, and/or if there is a problem with the GPS
receiver or antenna or both at the time of power-up, this test will indicate FAILED. “Antenna
UC” means the antenna was not connected and “Antenna OC” indicates there was a short in the
cable at the time of power-up. “Antenna NV” means an unknown antenna problem existed at
power-up. “GPS & Antenna” means that both GPS receiver and Antenna problems were
detected at power-up.
GPS Antenna Sense
– The GPS Antenna Sense is a current status of the antenna, antenna
cable and the GPS receiver. If the antenna cable is currently not connected, shorted or open,
and/or if there is a problem with the GPS receiver or antenna or both, this test will indicate
FAILED. “Antenna UC” means the antenna is not currently connected and “Antenna OC”
indicates a short in the cable. “Antenna NV” means an unknown antenna problem. “GPS &
Antenna” means that both GPS receiver and Antenna problems were detected.
Modem Test
(Applicable only to units with Option 03 installed) – The Modem Test will indicate
“Console Mode” if the Serial Setup Interface is set to Console mode instead of Modem mode.
This indicates that the modem is not currently being used. If the modem feature is desired, in
the modem configuration page, change the mode to the Modem mode.
When the NetClock initially boots up, the mode is set to Serial Setup Interface. When the mode
is set to Modem and before every modem dial-out call, the modem is sent a command. If the
unit gets a response from the modem, the field is set to PASSED. If the unit gets no response
or a bad response from the modem, then the field is set to FAILED and the reason is indicated
as shown below:
Reasons:
Not Found
– There is no modem connected, the modem is incorrectly connected, or it is not
turned on.
Modem Error
– The modem gave a response indicating an unspecified problem.
The
System Features and Options
section provides the current status of all the features and
options that are available for your particular NetClock. Features that are currently turned on will
indicate “ENABLED”. Features that indicate “DISABLED” are not enabled. However, the
