I have followed the above instructions, but I still do not see USB in the drop-down box on the main window in Aqua4Plus, or Aqua4Plus Lite is saying that no USB ports can be found.

• Click the Start Button on your computer.
• Right-click on “Computer.”
• Click on “Manage.”
• In the left pane, click on “Device Manager.”
• You may need to update the first driver: In the right panel, under “Other Devices,” you may see a yellow exclamation point next to USB Comm. Right-click on this and then select Update Driver Software. This will update the first set of drivers. You should get a message saying that the USB Serial Converter has been installed. Close this window.
• Now you may need to update the second driver: In the right panel, under “Other Devices,” you may see a yellow exclamation point next to USB Serial Port. Right-click on this and then select Update Driver Software. This will update the second set of drivers. You should get a message saying that the USB Serial Port has been installed. Close this window.
• Restart Aqua4Plus or Aqua4Plus Lite.
• See the application note USB/RS485 Communication Cable Installation Instructions for more detailed information.
