Executing Switches
Before fine-tuning the system for its final location, route a few switches to check that the system is 
working properly and to determine what adjustments are needed.
This section provides basic information for executing switches using the CrossBar. For complete control

3. Click a crosspoint to execute a switch.
The crosspoint changes to an active state and the switch is routed. (Click an active crosspoint to 
disconnect a switch.)
