Description
Select this option if you want to send GPS data in GGA syntax to an NMEA server.
Select this option if you want to send GPS data in GGA syntax to a device connected to
the serial port of the TVG unit. The data is sent at 4800 baud, 8 bits, no parity, one
stop bit (8N1).
If you opted to send either RMC or GGA data to an NMEA server, fill in the IP address
or hostname of the server.
If you opted to send either RMC or GGA data to an NMEA server, fill in the port used to
by the server to receive NMEA data.
If you opted to send either RMC or GGA data to an NMEA server, specify how often the
NMEA data should be transmitted to the server, in seconds. Recommended value: 30.
Note: This value should be a multiple of the GPS Frequency value, and should not be
higher than the GPS Frequency (i.e., the NMEA Frequency should not be set to a
smaller number of seconds than the GPS Frequency). If it is, the GPS Frequency
actually follows the NMEA Frequency.
If you chose to send RMC data, specify how much data should be stored for sending
later if the unit fails to send the data to the RMC server.
Erasing Recorded GPS Data
Recorded GPS data is normally stored on the unit's storage media until it is over-written by newer data. You can
also erase all GPS data from the unit manually.
To erase all recorded GPS data from the unit's storage media:
• In the System Summary screen, under GPS, click Erase GPS Recordings. The recordings are erased.
Figure 24: Erase GPS Recordings
Note: The Erase GPS Recordings button only appears if GPS recording is enabled in the General
System Settings screen (see Configuring GPS, page 26).
Configuring a CCTV Monitor (TV-Out)
If a video monitor is connected to your TVG, you must activate and configure it before you can see video from the
TVG on it.
NOTE:
For information about setting up a CCTV monitor, please refer to your unit’s installation guide. For
information about viewing video on a connected CCTV monitor, see Appendix A: Viewing Video on a
CCTV Monitor (TV-Out), page 170.
