PI5 Tech Notes

PCI card slot compatibility

TN0265

Product: PI5, PO5
Version: All
Date Added: 2007-09-20

Issue

The PI5 and PO5 cards should only be installed in (PCI v 2.2 or greater) compliant 3.3 V slot. The PCI standard has changed and evolved through the years with varying degrees of backwards compatibility, however, most computers purchased since 1998 will support the PI5 and PO5. Problems with compatibility typically manifest as communications errors and can be hard to troubleshoot. This tech note can help you verify that your computer's PCI slots are compatible with the PI5 and PO5.

The early versions of the PCI standard (v 2.2) supported 5 Volt cards. When PCI 3.0 was released in 2002, all 5 Volt PCI slot support was removed in place of 3.3 Volt compatibility, however, 5 Volt slots can still be found on older machines. To avoid 5 Volt slots, check your computers specifications or carefully check the PCI adapters on your computers motherboard and compare them to the diagram below.

As illustrated in the figure above, 3.3 Volt PCI slots always have the PCI key close to the back of the computer tower unlike the 5 Volt slots that are furthest away from the back of the computer tower.

You will need to avoid PCI-X slots. These 64-bit slots will be notably longer than the PI5 and PO5.

PI5/PO5 Gigabit Interface not recognized after installation. File wdpnp.sys needed

TN0246

Product: PI5, PO5
Version: All
Date Added: 2007-03-18

Issue

After a PI5 or PO5 card is installed into a PC and the system is restarted, the Found New Hardware Wizard is launched. As the wizard is run it may display a Files Needed dialog box with the message "The file 'wdpnp.sys' on WinDriver Installation Disk is needed."

Solution

To Complete the Found New Hardware Wizard, you'll need to provide additional information about the location of a device driver called wdpnp.sys.

If you installed the TDT Drivers from files on a CD, ensure that it is in the CD drive. If the Files Needed dialog box is displayed, click Browse and navigate to the CD Drive. Select the wdpnp.sys found in the main directory of the TDT CD and complete the wizard.

If you installed the TDT Drivers from files downloaded from the TDT website, when the Files Needed dialog box is displayed, click the Browse button and navigate to the folder in which the drivers are located (typically C:\WINDOWS\system32\drivers). Select the wdpnp.sys file and complete the wizard.

Hardware conflict with PI5 or PO5 PCI card.P

TN0204

Product: PI5, PO5
Version: All
Date Added: 2006-02-27

Issue

After installing the Gigabit or Optibit PCI card in your computer, there may be a conflict with how the PC communicates with the card and other devices in the system.

This could lead to the following error message when performing a transfer test in zBUSmon: "System Test Error: Cycle power on system and test again".

Workaround

Check the hardware settings for the PCI card in the Windows Device Manager. Locate the "Jungo" card and check the Properties. Under the Resources tab, check the Setting of the Resource Type IRQ (Win XP) or Interrupt Request (Win 2000). On some PCs this number may be shared with another device, such as a USB Host Controller.

If you experience system problems and find the IRQ number to be the same on another device, then you should move the PI5 or PO5 card to another PCI slot in your machine. You will be required to go through the Windows Found New Hardware Wizard again to assign the card drivers properly. This should change the IRQ setting for the TDT card, eliminating the previous conflict.

Important

The PI5 or PO5 card needs to be installed into a (PCI v 2.2 or greater) compliant 3.3 V slot, and not in a PCI-X or PCI Express slot.

Hibernate and Standby cause communication failure

TN0174

Product: PI5
Version: All
Date Added: 2005-03-28

Issue

When using the Gigabit PC interface, TDT hardware is not compatible with the Windows Standby and Hibernate features. These features automatically set your computer to a low power state or turn it off to conserve power during periods of inactivity. When your PC goes into one of these modes communication will be lost between your PC and System 3 Hardware. When activity resumes any software actions that require communication with the hardware will fail. You will also get a Null card error on opening zBusMon.

Solution

We recommend configuring PC Power Options to never use these modes when using your PC for TDT applications.

To configure power options:

  1. Right-click the Windows desktop and click Properties

  2. In the Display Properties dialog box click the Screen Saver tab and click Power.

  3. In the Power Options Properties dialog box, choose Never for each Standby and Hibernate setting.

PA5 in the right slot randomly resets to 0

TN0164

Product: PI5, FI5
Version: 6 (red dot)
Date Added: 2005-01-13

Issue

When a PA5 is mounted in the right, front slot of the zBus caddie, a set attenuation command will fail to attenuate the signal and the PA5 will reset to 0. This is the result of a communication failure associated with the Red Dot PI5/FI5 Gigabit Interface.

Workaround

This issue is resolved with v60 of the TDT Drivers. Upgrade to v60 to eliminate this issue.

PA5 Attenuation cannot be reset

TN0138

Product: FI5, PI5
Version: 6 (red dot)
Date Added: 2004-09-01

Issue

Setting the attenuation of a PA5 mounted in the left side of a device caddie, fails after a few updates. SetAtten returns 0 and GetAtten returns the previous value.

Workaround

Put PA5s in the right side of the device caddie.

'Access to path and application was denied' error message

TN0124

Product: PI5, FI5
Version: PI5 with serial numbers < 2000 and FI5s with serial numbers < 5000 (and marked with an Orange Dot on the Face Plate)
Date Added: 2004-04-13

Issue

On some systems using the Gigabit interface, problems with synchronizing device caddies and timing of data transfers cause large data transfers or repeated short data transfers to fail. When the failure occurs OpenEx users might see any of several error messages. The most common is:

... Trouble saving data to tank. ...TTank Server Error ... Server Call: TankError Error: Tank unable to cache events ...

Users might also see errors such as:

  • Trouble saving data to tank....

  • Trouble accessing target ...

  • Trouble reading data from device ...

However, these errors might be also be symptoms of other less serious problems, such as incorrectly defined targets.

Solution

This issue has been resolved with design improvements to the Gigabit high-speed interface. These modifications improve Gigabit stability, error checking, and overall performance and include modifications to the TDT Drivers software, the firmware on the PI5 card, and the FI5 Gigabit modules that reside in the zBus device caddies. An upgrade package including: a PI5 upgrade chip, a TDT Drivers v56 (or later) CD, and replacement FI5(s) (marked with a red dot on face plate) will be sent to customers who purchased the affected interfaces. If you are experiencing problems, contact technical support for assistance.

CPU usage goes to 100% when transferring data from TDT hardware to the computer

TN0046

Product: PI5, FI5
Version: All
Date Added: 2002-08-30

Issue

When data is being transferred from the TDT hardware to the computer, CPU usage on the computer goes up to 100%. This is typically seen when doing a ReadTag from a large buffer. The computer is still usable (can ran other programs, etc.) despite the high CPU usage, however, other programs that are running on the computer may slow down.

PCI slot requirement for the Gigabit and Optibit Interfaces

TN0035

Product: PI5, PO5
Version: All
Date Added: 2005-12-15

Issue

The PI5 and PO5 zBus to PC interface cards must be installed in a standard size, PCI version 2.2 compliant (that is, slots with a 3.3 Volt power supply).

Important

While these cards have a notch for a 5 Volt slot and a notch for a 3.3 Volt slot and will plug into either, they will only work when plugged into a 3.3 Volt slot.

Do not install in a PCI-X slot—the interface might fail.

Do not attempt to install in low-profile PCI slots. While low-profile and standard PCI cards maintain the same electrical, protocols, PC signals and software drivers as standard PCI expansion cards, the low-profile bracket is not compatible with standard cards.
