Editing the HP E8491A Resource Manager Configuration 73Appendix B
The irq.cf Configuration
File
The irq.cf file is a database that maps specific interrupt lines to VXI interrupt
handlers. If you have non-programmable interrupters and you want the
interrupters to be recognized by a VXI interrupt handler, you must make an
entry in this file. Additionally, if you have progammable interrupters and
you want them to be recognized by a device other than what’s assigned by
the resource manager (the commander of that device), you can make an
entry in this file to override the default. Keep in mind that not all VXI
devices need to use interrupt lines and not all interrupt lines need to be
assigned. Note that any interrupt lines assigned in this file cannot also be
assigned in the vmedev.cf configurtion file.
This file is edited by selecting “Edit mapping of VXI devices to interrupt
lines” in the Resource Manager window (Figure B-2).
The ttltrig.cf
Configuration File
The ttltrig.cf file contains the mapping of VXI devices to TTL trigger lines
in extended VXI systems. If you have a MXI-extended
(multiple-mainframe) system and you are sending / receiving triggers
between mainframes, you must map the TTL trigger line to the logical
address of the device asserting the trigger. This file is only used for extended
VXI systems.
This file is edited by selecting “Edit mapping of VXI devices to ttl trigger
lines” in the Resource Manager window (Figure B-2).
The vximanuf.cf
Configuration File
The vximanuf.cf file contains a database that cross references the VXI
manufacturer id numbers and the name of the manufacturer. The ivxirm
utility reads the manufacturer id number from the VXI device. The ivxisc
utility then uses that number and this file to print out the name of the
manufacturer. If you add a new VXI device from a vendor that is not
currently in the file, you may want to add an entry to the file.
This file can not be edited using ‘I_O Config’.
The vximodel.cf
Configuration File
The vximodel.cf file contains a database that lists a cross reference of
manufacturer id, model id, and VXI device names. The ivxirm utility reads
the model id number from the VXI device and the ivxisc utility uses that
information and this file to print out the VXI device model. If you add a new
VXI device to your system that is not currently in this database, you may
want to add an entry to this file.
This file can not be edited using ‘I_O Config’.
Utility Function
Overview
Within the <drive:>\siclnt\bin or \sicl95\bin directory are utility functions
that view the resource manager output (ivxisc) and which clear the
HP E8491A interface (iclear) and run the resource manager (if the iproc
utility is running).
Using ivxisc The ivxisc function is used to view the resource manager output. ivxisc is
executed from the Windows command (DOS) prompt (..\siclnt\bin or
\sicl95\bin directory) as:
ivxisc vxi<logical unit>
