FIGURE 2-2: LOGICAL ADDRESS EXAMPLE 2

Here is another way of looking at the conversion:

LA = (back switch x 16) + front switch

 

LA = (1 x 16) + 9

 

LA = 16 + 9

 

LA = 25

Set the address switches to FF for dynamic configuration. Upon power-up, the resource manager will assign a logical address. See Section F - Dynamic Configuration in the VXIbus Specification for further information.

There is only one logical address per SMIP II base unit. Address assignments for individual modules are handled through the A24/A32 address space allocation.

SELECTING THE EXTENDED MEMORY SPACE

The Extended Memory Space of the SMIP II is set by a dip-switch that is located on the bottom edge of the interface card. Position 1, located to the left on the dip-switch, selects between A24 and A32 memory address space. In the UP position, the SMIP II will request A24 space. In the DOWN position, the SMIP II will request A32 space. (Position 2 is not currently used.) The selection of the address space should be based upon the memory allocation requirements of the system that the SMIP II module will be installed. The amount of memory allocated to the SMIP II module is independent of the address space selected.
