zError: ZGB8 after upgrading drivers.

Tech Note: TN0897
Product: TDT Drivers
Version: All
Date Added: 2012-04-24

Issue

When upgrading from an older version of TDT drivers, some PCs may reuse old hardware drivers during the automatic PCIe card driver update. This causes a communication error in zBUSmon that returns zError: ZGB8.

Workaround

To resolve this issue, update the device driver manually.

To manually update drivers using Windows 7:

  1. Press the Start button.

  2. Right-click My Computer.

  3. Select Manage.

  4. Select Device Manager.

  5. Select TDT.

  6. Right-click Tucker-Davis Technologies PO5/PO5e Card.

  7. Click Update Driver Software on the shortcut menu.

  8. From the driver update wizard, select Search Automatically.

  9. If windows is unable to locate the drivers automatically, choose to Browse then search your computer's C:\ drive for the driver files and click Next.

  10. If your PC recognizes multiple drivers, specify the version with the newest date. It should be dated 1/14/11 or newer and click Next.

  11. Reboot your PC and run zBUSmon to verify your device is working properly.

Note

If you receive a warning that the driver is "unsigned" or "not digitally signed" then continue with the update. This is just a warning related to Windows 7.
