Getting ChannelState

Getting the parameter ChannelState returns one of the four following values: ORPHAN, IDLE, READY or ACTIVE.

Orphan

When a channel is in the ORPHAN state, it has no grabber associated with it. Hence, image acquisition is not possible immediately.

However the channel exists and all its parameters can be set or get freely.

Idle

When a channel is in the IDLE state, it has a grabber associated with it. Hence, image acquisition is possible immediately.

In this state, MultiCam may reassign the grabber resources automatically to another channel.

Ready

When a channel is in the READY state, it has a grabber associated with it. Hence, image acquisition is possible immediately.

In this state, MultiCam cannot reassign the grabber resources automatically to another channel.

Active

When a channel is in the ACTIVE state, it has a grabber associated with it and performs an image acquisition sequence.

In this state, MultiCam cannot reassign the grabber resources automatically to another channel.
