This article has a training video for Double Ended Switchboard in COMPAS Go. 

Configuration Tips:

• When configuring a Double Ended Switchboard, without a TIE breaker the configuration requires a Key Interlock on both mains. Note: location/address information is required for both key locks. Keep the same KEY designation on related devices. When a Key can be physically removed the device is Open. The Key is locked in place when the device is Closed. 
• If the first Main is located on the left the second Main needs to be located on the right.
• If DAS is required, make this selection from Options before configuring the switchboard.
• DAS application requires Auxiliary Compartments.
• Think about what you want to build and let the tree be your guide.
