AMBus FireWire card – User's Guide
Working with Windows XP

General Notes

If you change the Apogee AMBus FireWire hardware connected to your computer in any way (i.e. you add
interfaces or change AMBus FireWire cards), it's necessary to uninstall and re-install the Windows XP
driver.

Troubleshooting

Symptom – When the driver instructs me "To finish the installation connect your device to this computer
and turn it on", I connect the device but nothing happens; the Apogee hardware is not recognized.
Solution – This indicates some sort of hardware problem:
• If you're computer and AMBus FireWire care are equipped with FW800 connections, be sure you're
connecting the AMBus FireWire card to the computer with a FW800 cable.
• Test the host interface on another computer if possible
• Verify the chipset of the computer FireWire connections. We have had the most reliable operation with
Texas Instruments or Lucent chipsets.
Symptom – The driver installation seems to have gone well, but the interface(s) don't appear correctly
in the"Safely Remove Hardware" window. Also, I don't see I/O in the Input Connections and Output
Connections windows of the Apogee 1394 Audio control panel.
Solution - If you're using SP2 and using FW800, run the Microsoft hotfix found here: http://support.
microsoft.com/kb/885222. After that, go to Add or Remove Programs in the Windows control panel,
uninstall the driver, power cycle the computer and Apogee host interface, and re-install the driver.
Symptom – I'm getting clicks and pops in my audio software.
Solution – Go to the Apogee 1394 Audio control panel's Settings window and increase the buffer setting
sizes.
Symptom – My AD16X, DA16X or Big Ben won't lock to the FireWire connection.
Solution – Increase the Stream buffer depth in the Apogee 1394 Audio control panel.
