5.1 GPS
The GPS menu screen is covered in Chapter 3 – User Guide – X300 Menu System - GPS
The X300 GPS menu options allow the embedding of GPS position and speed, assuming a valid GPS
signal is being received and the data passed correctly to the X300.
If a GPS receiver is connected but satellite lock has been lost then it is still possible to record the data
but it will not indicate position, speed, date or time and the actual content may vary according to the
type of GPS receiver employed.
The X300 Digital Video Recorder includes a clock which is used to timestamp recording files and
overlay the date and time on recorded images. Although accurate, the X300 can be configured to
synchronize the clock with the date and time information received from the GPS receiver.
When a GPS unit is plugged into the X300, and it has locked onto the satellites it then sends GPS time
and position and other data every second. If after 10 seconds the X300’s internal clock is consistently
+/- 2 seconds compared to the GPS unit then the time error is noted. On the next power cycle the
time error is corrected.
Local Standard Time - The time received from the GPS receiver is always UTC (Coordinated Universal
Time) which is the same as GMT (Greenwich Mean Time). In order to correctly work out the error
between the local standard time (used by the X300’s internal clock) and that received from the GPS
receiver, the system must be set with the correct time zone offset.
GPS Baud Rate - Set the X300 data rate according to the GPS module you are using. Rates
configurable include; 2400, 4800, 9600 and 19200, 38400 bps.
NB: It may be necessary to change the baud rate on the GPS module and set it to a specific rate in
line with the X300 setting. Reference the GPS module product instructions to configure the baud rate
then power off/on the X300 (whilst connected to the GPS).
