1 General
This evaluation oard can e used for GPS module Lassen IQ, ut for
CMOS camera CAM-VGA100 as well.
Camera CAM-VGA100 GPS module Lassen Q
2 Supply voltage
The input voltage should e 4.5V – 6V.
Input power should e off efore plugging in the GPS module or camera.
3 GPS module Lassen Q
If you evaluate a Lassen IQ, then please follow the guide line as elow,
else jump to chapter num er 4 (CMOS camera CAM-VGA100).
Link pins 1 & 2 of LK1 to select the NMEA channel.
No link LK2.
No link BAT for the GPS ackup attery.
Link pins of LK 4 to ena le power to the GPS receiver.
Connect HFL transition ca le to Lassen receiver.
Plug in the Lassen GPS receiver.
Link BAT for the GPS ackup attery.
Connect a straight-through 1 to 1 ca le etween your PC and the
evaluation oard.
Power on the evaluation oard.
Using HyperTerminal or similar you will now see the NMEA output from the
GPS receiver.

LK1
No links
Ena les the TSIP input and output on pins 2 & 3 of RS232 connector. You
should use this mode when using the GPS evaluation software and the
camera evaluation software. If you want to see the NMEA output it is
availa le on Pin1 of the RS232 connector.
1 & 2
Ena les NMEA output on pin 2 of RS232 connector.
2 & 3
RTS from PC controls TSIP or NMEA output.
LK2
Link OFF ena les RS232 transceiver. Keep this off for normal operation.
Link ON disa les RS232 transceiver. This will stop all data in/out to RS232
connector.
BATT
Link ON connects the Lithium ackup attery to the GPS receiver.
You’ll need this ON to get a quick fix after power off.
Link OFF disconnects the Lithium ackup attery to the GPS receiver.
LK4
Link ON ena les power to the GPS receiver and camera.
Link OFF power is controlled y the DTR line from the RS232 connector.

4 CMOS camera CAM-VGA100
LK1
No link
LK2
No link (If linked disa les RS232 transceiver)
LK3
Don’t care
LK4
Link to ena le power to camera.
(Unlink if you want to control power with DTR input.)
The VGA100 plugs into the 4 way socket. The outline of the camera shows
the orientation.
Use a straight-through 1 to 1 ca le from PC to evaluation oard.
The Round Solutions test software can e used to test the camera at
various JPEG resolutions.
NOTE
You cannot normally have the camera and GPS connected at the same
time.
If this is a requirement then you’ll need to remove R17 and R18. You will
not then have the TSIP availa le, only the NMEA output and camera. The
GPS TSIP and camera share the same channel.
