GPS TIME
A very accurate time source is embedded in the GPS satellite
signal. Set the
GPS TIME
to
ON
to synchronize the
DVR
’
S
internal clock to the GPS satellite time. Because the GPS
satellites do not know where the GPS receiver is, the GPS
signal sends Universal time, or
UTC
time (also known as
Universal Time Coordinated.)

UTC TIME REF UTC
is referenced to the atomic clock standard in Greenwich,
England. The
DVR
location is a certain time difference from
UTC
time. For example, Eastern Standard Time is –5 hours
from
UTC
time. Pacific Standard Time is –8 hours from
UTC
time.
To use
GPS
time, determine your time difference from
UTC
time and enter this time into the
DVR
. Use the time reference to
standard time. The
DVR
keeps track of the Daylight Saving
Time changes internally (if auto daylight saving is set to on).

SPEED DISPLAY
If speed is not being recorded, change the speed display option
to
OFF
. This turns off the 0 on the display which indicates zero
speed.
If speed is being recorded, there are three sources that the
DVR
can use to obtain vehicle speed:
•
a pulse counting input
• a
GPS
receiver
• vehicle
CAN
network.
Set the speed display option to the desired input type. All of
the speed input devices are optional. Contact your sales
representative at Seon Design to obtain the optimal speed
solution.

SPEED UNIT
If Speed is being recorded from the
GPS
receiver or the
CAN
network, then the desired speed display units must be selected.
Selecting the speed unit to be
MPH
makes the
DVR
convert the
GPS
signal to display speed in miles per hour.
If the speed display is set to pulse, the speed unit does not
matter as the calibration routine automatically sets the unit.
