How to Work With Input/Output Lines?
This section addresses the question of how to control general-purpose input and output lines (I/O) of a MultiCam compliant board.
Source of I/O control
Many I/O lines are shared items. This means that they can be activated from at least two distinct origins:
- A MultiCam channel
- An application program
Accessing an I/O line from a MultiCam channel obeys to a set of function-oriented MultiCam parameters belonging to the channel. This I/O functionality can be described as camera-specific.
Accessing an I/O line from an application program uses a consistent set of board-object MultiCam parameters implementing the general-purpose I/O functionality.
The Input/Output Control category
For a complete definition of parameters controlling I/O lines, refer to Input/Output Control Category.
Before using one of these parameters, a board should be selected by means of one of the channel-class parameters into the Board Information category.
