Using the HP-MSIB Troubleshooting Utility
The HP-MSIB Troubleshooting Utility is a firmware routine of the display instrument. It
allows you to verify that an element can communicate on the HP-MSIB. By determining
which elements can communicate, you can isolate the HP-MSIB problem. However, if the
problem is in the mainframe or the display, the utility cannot determine which is faulty. If
this is the case, contact your nearest Hewlett-Packard service office listed in Table 1-5.
Preparing to Use the Utility
To use the utility, you must know the HP-MSIB addresses of the elements. It is recommended
that you keep a written list of the HP-MSIB addresses.
Note
The address map may not function if there is an HP-MSIB problem. After an
i
HP-MSIB problem occurs, the address map cannot be relied on to determine
v
the addresses of the elements.
If you do not know the HP-MSIB addresses, they can be identified by checking the switch
settings on each module. The HP-MSIB addresses can sometimes be deduced from the HP-IB
address of the master and the response of the troubleshooting utility.
Note
The HP-MSIB Troubleshooting Utility inhibits normal operation of the
system. Using the utility may put the system to a state from which you can
y
only recover by cycling power.
When the HP-MSIB is not working, the troubleshooting utility cannot be used unless the
display is prevented from automatically communicating with other HP-MSIB elements. This
is done by purging all window assignments of the display.

following procedure to purge window assignments.
