Troubleshooting hardware installation problems – national instruments e gasoline


• Compatible Driver and Operating System Versions — Verify that the device is compatible with the driver version as well as the driver version compatible with the operating system. For more information refer to the device manual or the links listed below.

• Conflicting Drivers — Make sure you do not have multiple versions of the driver software installed on your computer. If you have multiple versions installed, remove all versions and reinstall the latest version of the driver software by completing the uninstall/reinstall steps.

Installation Wizard — If the driver was not installed from the Installation Wizard it is possible that the wrong installer file was chosen. Often there are multiple installer files for the driver which are chosen for the specific operating system. Using the installation wizard will ensure that the driver for the correct operating system is chosen.

• Windows Device Manager — National Instruments software will not recognize hardware that is not recognized by the operating system. Make sure that the device shows up in the Windows Device Manager. To access this go to Start » Control Panel » System » Hardware » Device Manager.

• Cannot find the driver — If you find your device under Other Devices with a yellow question mark on it, and the properties show error: Code 1: Device not configured correctly. Cannot find the driver. There was a problem with the driver installation. Refer to the sections above on Installation Order and Installation Wizard.

• Refresh Measurement & Automation Explorer (MAX) — Older versions of MAX do not refresh automatically when a new device is installed. To refresh MAX, press or select View » Refresh. The device should now appear under Devices and Interfaces. MAX 3.0 and later refreshes every time you launch MAX.

• Power Requirements — Verify the device has the 5 V power supplied from the motherboard. If the power supply delivers an insufficient voltage (i.e., it is too low), then the PCI board will not function. This may happen if you have a custom-built system with a separate power supply. Also, some devices require a 3.3 V source as well. Check the device power requirements and verify that all required power is supplied.

• Try a Different Slot/Port — Shut down your computer and install the device in a different slot/port. This is done in case the slot is not damaged. If you do not have another slot/port available, swap your device with another device that is working in the same type of slot/port.

• More than One PCI Bridge — Some PCs have more than 4 PCI slots, which means that they probably have more than one PCI bridge on the PCI bus. The first PCI bridge connects the CPU to the PCI bus. Additional PCI bridges connect one part of the PCI bus to the next.

• PCI Bus Mastering — Most PCs have a BIOS setting called PCI Bus Mastering that enables or disables the ability of a PCI device to become the master of the PCI bus during data transfers. Some PCs have this setting disabled by default, but it should be enabled for your PCI-GPIB device to work properly; otherwise, you may experience timeout errors (EABO) during writes and reads.

• Resource Conflicts with Other Hardware — PCI resources are assigned in the BIOS. You may need to enter your BIOS/Setup to correct the problem, but before you do that, try removing other devices from your system to see if this corrects the problem.

• (Older Windows Versions – NT 4.0 and 95) PNP BIOS Switch Problem — PCs usually have a setting in the BIOS that allows you to indicate whether you have a plug and play operating system on your machine. Because Windows NT is not a plug and play OS, this setting should be set to No.
