Table 53 shows possible DS30 and offset configurations for each type of station module, and the
corresponding switch settings. Note that offset 1 indicates the density mode for DSM 16+ and
DSM 32+ modules (SDD = single density, offset 1:on; FDD = Full Double Density, offset 1:off).

Each shaded square represents the amount of the DS30 bus, and the offset, which the module requires.
*If your system is configured for Partial double density (PDD), DS30 6 will support only modules set to single density
(SDD) and it supports Companion.
**If your system is configured with a 3/5 DS30 split, DS30 7 is not available to media bay modules.
If your system is configured for PDD and a 2/6 DS30 split, DS30 7 will support only single-density modules, but it will
also support Companion. (Note: DSM 32/DSM 32+ (set to single density) modules cannot be deployed on this bus.)
***ASM modules always use the single density dip switch settings, with the appropriate offset.
****If your system is set to PDD, offsets 2 and 3 are not available to ASM8 modules.
