3.4.4 Satellites Used
This shows the current number of satellites that are in view and locked by the GPS receiver.
3.4.5 GPS Fix
This displays the level of the current GPS lock.
No GPS Fix – Check cable connections. If connected correctly, likely the antenna needs a better view
of the sky. Obstructions, building materials, window tinting can all cause possible signal issues.
2D - GPS satellites found.
3D – Required for serving time.
3.4.6 NTP Lookups
This field updates on a page reload and shows how many NTP time requests have been requested from
client devices.
3.4.7 Holdover Time
When the GPS lock is lost and time is being served by the internal OCXO, this will show the amount of
time in minutes that the holdover state has been active.
3.4.8 MAC
This is an information only field and displays the MAC address of the Time Server.
3.4.9 Uptime
Time elapsed since last boot up.
3.4.10 OCXO Correction
This field shows the frequency correction being applied to correct the OCXO back on to its root
frequency. This value can be saved or reset from this web page. The purpose of saving this value, after
the device has run for a period of a couple hours with 3D lock, is to give a more accurate starting point
for the correction algorithm to begin on power up. If for some reason the value seems wrong or not
working, a Reset is allowed that will, after a reboot, start the algorithm from default and restart the
correction process.
If using the TM2X00B for manual NTP time generation, having the device on the GPS for a period of
time to determine the correction, then saving it, will dramatically improve drift of the TM2X00B when
operated without GPS reception.
3.4.11 Version
Displays current software version running on device.
3.4.12 Satellites
This table shows the current list of locked satellites, their signal strengths (SNR), as well as their
current location over the planet. Refreshing the web page updates the table to their current values.
