Utility Function Overview

Using ivxisc

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 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 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 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’.

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).

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>
