To Leave READY State

Setting ChannelState to ACTIVE

Setting the parameter ChannelState to ACTIVE starts an acquisition sequence.

Because all required grabber resources are available, the command takes effect immediately.

Setting ChannelState to FREE

Setting the parameter ChannelState to FREE releases the associated grabber resources.

If the resources release is possible, the command takes effect immediately and ChannelState becomes ORPHAN.

It may happen, on Domino Alpha 2 with two cameras in master synchronization mode, that ChannelState remains READY. By simply reading back ChannelState, the application is informed of the success or failure of the setting.

As long as ChannelState remains READY, the application can retry as many times as necessary to set ChannelState to FREE.
