4x16 switch settings
The 4x16 MBM combines a CTM and a DSM16. The CTM only requires four lines on the DS30
bus. Therefore, it can be assigned any of the four offsets in a DS30 bus. The DSM then
automatically assigns the next DS30 bus and all the assigned DNs.
The 4x16 MBM can be combined with three other CTMs or one CTM8 on the same DS30 bus.
