Operating the camera
Power for the camera is supplied either via the FireWire™ bus or the camera
I/O connector’s pin 7.
The input voltage must be within the following range:
Vcc min.: +8 V
Vcc max.: +36 V
Control and video data signals
Guppy cameras have 1 input and 3 outputs. These can be configured by soft-
ware. The different modes are described below.
Note

•
An input voltage of 12 V is recommended for most effi-
cient use of the camera.
•
As mentioned above: The camera I/O connector sup-
plies power to the camera via a diode. This means that
there is no power out at pin 7 if the camera is powered
via the bus. Consult the factory if you need power out-
put at this pin instead of power in.

The Guppy outputs are not short-circuit-proof.
If there occurs a short-circuit at the outputs, the
output
driver will be damaged
