IBCONF makes changes to the GPIB.COM file, which should also be in
the root directory. If you want IBCONF to make changes to a different
copy of GPIB.COM such as GPIB2.COM , enter the path and name of
the GPIB.COM file you want modified:
ibconf c:\GPIB-PC\GPIB2.COM
This will have the effect of changing the parameters within the
GPIB2.COM file in the GPIB-PC subdirectory.
Modify only the copy of GPIB.COM created by IBSTART in your boot
directory. Never modify the master copy on the distribution diskette.
This would happen if you ran
IBCONF from the distribution diskette and
if the distribution diskette were not write-protected.
Upper and Lower Levels of IBCONF
IBCONF operates at both an upper and a lower level. The upper level
consists of the Device Maps and gives an overview of the GPIB system
as defined within the handler being configured. The lower level consists
of screens that describe each individual board and device in the system.
Upper Level - Device Map for Board GPIBx
This screen displays the names of all devices defined in the handler file,
and indicates which devices, if any, are accessed through the interface
board
GPIBx . At this level, you may:
• Rename a device;
• Disconnect a device from its assigned GPIB-PC access board or
connect (reassign) it to a different access board; or
• Proceed to the lower level to edit or examine the
characteristics of a particular board or device.
Instructions are given on the screen for selecting the individual devices
and for changing from one device map to another, for example, from the
map for
GPIB0 to that for GPIB1 .
