Camera interfaces
7.4 Operating the camera:
Pow for the camera is supplied either via the FireWire™
CCD models only).
er bus or the HiRose conector’s pin 2
-
+36 V
An input voltage of 12 V is recommended to make most efficient use of the camera.
As mentioned above for the CCD-models: The HiRose connector supplies power via a diode
to the camera. This means that there is no power out at pin 2, when the camera is powered
via the bus. Consult the factory, if you need power output at this pin instead of power in.
7.5 Control and video data signals
The camera has 2 inputs and 2 outputs. These can be configured by software. The different modes
are described below.
7.5.1 Inputs
All inputs have been implemented as shown on the diagram below.
(
The input voltage must be within the following range:
Vcc min.: +8 V
cc max.: V
