There may be up to 33 devices (zones) on bus 2, each with a unique physical address used by the bus. The logical
address is what the user is presented. By default, the RMA PLUS occupies logical address 7 of segment 2. You must
ensure that each device on this bus has a unique logical address within its segment. Segment 2 devices may include
EZ-ZONE RUIs and a sole EZ-ZONE RMZ (always address 8).
The segment field only applies to bus 2 records.

Standard Bus Address Space
Intermodule Bus
There may be up to 17 devices (zones) on bus 1. All are masters, so they may initiate requests to their peers. By default,
the RMA PLUS occupies address 17, which does not conflict with any other EZ-ZONE RM module. The segment field
should be set to 0 (not segmented) for any bus 1 record.
The logical address is software selectable and may be changed using one of the PC software tools. It is recommended
to leave the RMA PLUS at address 17 as this is a reserved address space.
