The CAN cable between a VBOX / Video VBOX Pro and a Mini Input Module can be connected to either the DATA1 or DATA2 socket as they share the same CAN connections.
Two CAN connections are provided to allow the Mini Input Module to be daisy chained with more VBOX input modules. The cable needs to be ordered separately.
The data connection between a VBOX Mini and a Mini Input Module is an RS232 serial data link that is only present in the DATA2 socket. The cable needs to be ordered separately.
