Connecting Instruments to GPIB 3
Agilent Connectivity Guide 63
Check Device Manager You can use the Windows Device Manager
to reinstall the interface card as required. For example, open the
Control
Panel
.
Then, select
System > Hardware > Device Manager. From Device
Manager, select
the interface card and then Properties. Tab to Driver and
click Update Driver or
Reinstall Driver. This allows the Windows Plug
and Play Manager to begin searching for a driver for the interface card.
Since Device Manager may have disabled the card device, click
Enable
to restart the card. If this does not resolve the problem, go to GPIB
Software Checks.
If your sound card stops working after configuring interfaces, disable
the auto-detection process in Connection Expert. Click Tools >
Options... . Then de-select Automatic discovery or refresh of I/O
resources under the Configuration Settings tab.
If Data Transfers to Devices Fail If devices attached to your ISA
(82341) GPIB card are detected, but data transfers to those devices fail,
this is usually caused either by an IRQ conflict with another card or by
your system having no IRQs available for this card. If no IRQs are
available, the IRQ value shown in Connection Expert will be -1.
Try changing the IRQ setting to other values. You must reboot after
changing the value to test it. If none work, you will have to free up other
IRQs by disabling devices such as serial ports or sound cards.
If Connection Expert Finds an Agilent 82350 Card with Serial
Number
ffffffff If Connection Expert reports finding an 82350 card
with serial number ffffffff, this is typically caused by a Windows system
configuration that results in failure to properly configure PCI cards. In
this case, upgrade your system BIOS to the latest version. Note that
even new computers tend to have new BIOS available.
