Control And Video Data Signals; Inputs - Allied Vision Technologies F-201B AVT Dolphin Manual

Input voltage of 12V is recommended to make most efficient use of the camera.
The camera does not supply voltage to the FireWire™ bus if it is being receiving power
via the HiRose plug.

Control and video data signals

The camera has 3 inputs and 3 outputs. These can be configured via matching registers
(see section
6.5.1

Inputs

All inputs have been implemented as shown on the diagram. IO_INP_CTRL1Polarity is
controlled via the IO_INP_CTRL1..3 register (see section IO_INP_CTRL1)

The inputs can be connected directly to +5V. If higher voltage is used an external
resistor will have to be placed in series.

+24 V
Warning: Voltage above +45V may damage the optical coupler.
All input signals (Input 1...3) are inverted by the optical coupler.
