Chassis connections for both units are organised as below.
1 connects to the first expander chassis (which has its three ID switches configured to address 2)
2 connects to the second expander chassis (which has its three ID switches configured to address 3)
…
8 connects to the eighth expander chassis (which has its three ID switches configured to address 8)
The addresses are set 2,3,4…8 to fit logically with the processor chassis virtual address of 1. If more
than eight chassis are needed, a second expander interface is required. The address switches on
these chassis are also set 2,3,4…8 but the virtual addresses (as seen by the application and
diagnostics) are 9,10,11…15 as set in the System.INI configuration.
Refer to PD-8300 for further explanations on ID settings.
