Installation and Maintenance Guide
On these two tables, note that the modules only use the top 16 DNs for each DS30 bus occupied. In a single-density configuration, it does not matter if the bus is FDD or PDD, only the top 16 lines can be accessed.

1 If your system is configured with a 3/5 DS30 split, you cannot use DS30 07 for the DSM 16 module. You cannot
configure the DSM 32 module for DS30 06 because the second set of DNs cannot be accessed.
2 The extensions listed are based on a three-digit DN with a Start DN of 221. If your system has longer DNs or a
different Start DN, enter the range in the blank column.
