Control and video data signals
The inputs and outputs of the camera can be configured by software. The differ-
ent modes are described below.
Inputs
Triggers
The signal can be inverted. The camera must be set to external triggering to
trigger image capture by the trigger signal.
Input/output pin control
All input and output signals running over the camera I/O connector are con-
trolled by an advanced feature register.
The TiedToOutput field indicates that an output and the corresponding input
share the same physical connector pin. Pins with TiedToOutput set to 1 can be
used as an output or input.
Note
For a general description of the inputs and warnings see the
1394 Installation Manual.
