KXUSB to Serial Adapter Troubleshooting

• If you are having difficulty, connect your computer and KXUSB directly to your PX3, without any intervening USB hubs or a KXPA100 amplifier.
• Verify that the USB to Serial Adapter's device driver is up-to-date. To determine the currently installed device driver's version:
  • Plug the KXUSB USB to Serial Adapter into a USB port on your computer
  • Open the "Start" menu
  • Right click "My Computer" or "Computer"
  • Select "Manage"
  • In the Computer Management left pane, select "Device Manager"
  • In the right pane, select the "+" next to "Ports (COM & LPT)" to expand the Ports list
  • Double click the COM port entry for your USB to Serial Adapter.
  • The "Driver" tab contains the "Driver Version".
  
• After installing a new device driver, take a moment to verify that it was actually installed by viewing the Driver tab again. If the new driver did not install, it may be necessary to uninstall the old device driver before installing the new driver.
• Try a different USB port on your computer.
• Try a different USB to Serial Adapter.
• Try a different computer. Some combinations of USB to Serial Adapter and USB port are more reliable than others. For example, some laptop computers may not provide sufficient power to USB devices for reliable communications.
• One user reported that his USB to Serial Adapter did not work well when connected through a USB Hub.
• Some users have found better results with separately powered USB hubs rather than those that receive power from a USB port.
• A laptop computer's USB port may work more reliably if the laptop is powered by an AC power supply rather than its batteries.
