The following image shows how this layout looks in the Summary window when congured. Notice that displays

connected on COM1 can have the same IDs as those on COM2 because they are on separate daisy-chains.

Note: This type of connection that uses two or more separate COM ports cannot be fully congured using the Layout Wizard.

Use the Layout Wizard to congure the video wall size and rst COM port, then manually edit the connections for each

display using the Connection Panel to set the other COM ports to use and Monitor IDs.
