The acquisition board and the local processor unit (LPU)
provide the electrical connections from the module to the mainframe. These
electrical connections include power distribution, processor communications,
and intermodule communications.
Logical Address Switches.
The logical address switches determine the logical
address of the module. These switches should normally be set to address FF. For
more information on these switches and their settings, refer to
Logical Address
on page 2--1.
Most user information for operating the logic analyzer module is available

The logic analyzer module performs power-on diagnostics each time you power
on the mainframe. The Calibration and Diagnostics property sheet appears at
power-on if one or more of the diagnostics fail.
For more detailed tests, you can execute the extended diagnostics or the self
calibration. For more information on the diagnostics, refer to
Calibration and
Diagnostic Procedures beginning on page 6--31.
NOTE
. For best results, only run the diagnostics with the probes disconnected
from the module.
