1. Indicate the modules you want to install
2. Note how many DS30 buses each module requires

3. Choose the DS30 numbers to
assign to the modules
Example: Position your DSM 32 MBM (step 1), which requires two full DS30 buses (step 2), in
DS30 2 and 3 (step 3). Moving across, note that the offset is 0 (step 4). Set the DIP switches on the
MBM to match the DIP switch settings indicated for that offset (step 5).
