Shows the time zone from the settings page as an offset from GMT. Subtracting this from the Date/Time
display will show the current local time.

This shows the current number of satellites that are in view and locked by the GPS receiver.
3.3.5 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 Update Page.
The update page is used to update firmware of the unit. The firmware updates will be archived and available
for download from the css-design.com website. Save the file to the local computers drives. Most likely the
file will need to be unzipped. The file type that is used for the update is a .img file. Browse to it using the
Choose File button on the Update Page. Once the file is found the update can begin. This process takes 20 to
25 minutes and power should not be removed during the process or the device may be unrecoverable. There
are periods of time where there may be little or no indication of the update process occurring, so its
important to give it plenty of time. Once completed, the unit will reset and resume operation. Login to the
device with a web browser to confirm the version update.
3.5 Diagnostics Page.
3.5.1 Diagnostics.
The button and check box associated with this portion of the web page is used to turn on and off NMEA string
dump into the log file. Turning this option on and leaving it on for long periods of time is not recommended
as it will increase the size of the log files dramatically.
3.5.2 Download Log Files.
Clicking the Download button will cause the VZ2 to create a binary format log file and initiate an HTTP
download. The binary log can be used by CSS as an aid in troubleshooting.
