Encoding
Set-up
If using an external power supply attach it to socket A indicated on the unit.
Connect the GPS antenna to socket B indicated on the unit.
Connect the phono/mic’ lead to the signal phono on the CamNav (socket C) and the 3mm
jack plug into the camcorder microphone socket.
Set the Encode/Decode selector switch to ‘Encode’ as indicated (switch set toward the
data connector).
Switch on the CamNav and observe the three LED indicators. The red LED will flash at
approx 1 second intervals followed by the orange LED at a lower rate.
When the green LED flashes constantly at 1-second intervals the GPS receiver has a
position fix and recording can commence.
Positioning of GPS Antenna
The GPS antenna should be positioned with as clear a view of the sky as possible. A lock
cannot be achieved if the antenna is used indoors or in too built up an area. The antenna
can move but consideration to the ‘open sky’ requirement should be maintained.
Power Supply
CamNav runs from either its internal battery or an external supply. The internal battery is
of type PP3 (9Volts-500 mAh), Duracell Ultra or similar is recommended. An external
supply must be a dc supply, such as a 12 Volts dc (car supply) with a 15 Volts maximum.
The power supply specified above should be connected after all other connections are
made.
Use of Microphone Adapter
CamNav uses one channel of a stereo audio track to record the GPS data, thus ensuring
that the data and images are synchronized. Should you wish to record onto the spare
channel whilst encoding, you will need to use a microphone adapter which combines the
left and right hand stereo channels of the mic plug from two mono sockets.
Operation
Ensure the camcorder has a tape inserted, and the camera settings are as required. Start
the recorder running. The recording will now have the GPS data recorded onto the sound
track.
Ensure that the GPS antenna has a clear view of the sky and that any objects, which may
cut off the satellite signals, do not obscure it.
Note
, operation indoors, in buildings tunnels
etc., will not provide position fixes - indicated by the green LED
not
flashing.
