Chapter 8 Installing a media bay module (MBM) 119

Table 29 shows possible DS30 and offset configurations for each type of station MBM, and the corresponding switch settings. Note that DIP switch 1 indicates the density mode for DSM 16+ and DSM 32+ (SDD = single density, DIP switch 1:on; FDD = Double Density, DIP switch 1:off).

MBM set to offset 0 MBM set to offset 1 MBM set to offset 2 MBM set to offset 3 Each shaded square represents the amount of the DS30 bus, and the offset, which the MBM requires.

*If your system is configured with a 3/5 DS30 split, DS30 7 is not available to MBMs.

**ASM MBMs always use the single density DIP switch settings, with the appropriate offset.
