Installing Modules in the System
The annunciator modules begin annunciation with the CPU and continue
with the annunciation of circuits on the module installed directly after the
CPU. To ensure full employment of annunciator points, mount system
modules that require annunciation in the CPU row first, then in the second
row, etc. Modules with circuits that need not be annunciated by the system
should be installed further down in the cabinet.
Note: Without invoking the Eight-Point Shift, the first eight points would be dedicated
to CPU functions, not circuits of the first module. Refer to "Setting Rotary and DIP
Switches" on page 28.
