3. Click Update Now (see figure 19 on page 25). The volume settings are updated on the TVG immediately.
Note: All of the settings on the page are saved when you click Update Now. The volume settings are
implemented immediately, and the changes to the other settings are implemented after the unit is restarted (see
Saving Configuration Changes, page 125). If you modify the volume settings and click the Update button in
the lower-right corner of the screen, the volume settings are not implemented until the unit is restarted.
4. In the client application, listen to the audio from the video stream that is linked to the microphone.
5. Repeat steps 2–4 as necessary until the optimal volume setting is selected.
Configuring GPS
When GPS is enabled on an MVG or CVG-M unit, the unit uses the built-in GPS receiver to check its location at
specified intervals. Whenever you are connected to the unit through the MultiClient, the location data that is
received is automatically sent to the MultiClient. You can then use the MultiClient to view the last detected location
of the unit on a map.
If you choose to record GPS data, you can use the MultiClient to see the path that was taken by the unit before it
reached its last detected location. Recorded data is stored on the unit until the allocated disk space is filled; then, the
oldest data is overwritten by the new data. The unit can store over one million GPS data points – approximately 2
months’ worth of location data when the data is retrieved every 5 seconds.
If you have a server that can receive GPS data, MVG and CVG-M units can be configured to send the data to that
server at specified intervals. Alternatively, you can send the data to a device connected to the serial port (the
RS232/485 connector) of the TVG unit. (For additional information about this option, please consult your
vendor.)
GPS data can be sent in one of two syntaxes. These syntaxes are part of the NMEA (National Marine Electronics
Association) standard that defines the data required to process a GPS location. The available syntaxes are:
• SV-RMC: A modified version of Recommended Minimum sentence version C that includes some additional
information that is not included in the standard NMEA definition, such as the name of the sending unit. Please
consult your vendor for a complete description of this sentence.
• GGA sentences: Standard GGA sentences
Once the GPS data is received by your NMEA server or a device connected to the serial port, you can use it as you
wish – to display in a map, monitor vehicle locations and possible deviations from the intended route, or store the
data for future use.
NOTE:
SerVision does not provide any software for handling NMEA data that is transmitted to an NMEA
server. You must acquire and set up any required software on your own.
