Troubleshooting and Testing

Installation Problems​

  • Check the US Card is correctly installed, and the Ports appear in Device Manager without any errors (Errors are indicated by a yellow exclamation mark)

  • If the installation did not complete or shows any error messages then restarting the computer sometimes helps.

  • If Device Manager is still showing error messages, it is wise to uninstall and re-install. This should cure issues such as Resource Conflicts or failed installations. See Uninstallation and Installation Overview.

  • If the problem is still present after trying the above, try another laptop to narrow down the problem.

  • Should the problem still persist, please contact Brainboxes Technical Support

Communication Problems​

If you are experiencing communication problems:

  • Try removing the card and reinserting as this can sometimes help.

  • Check the US card is correctly installed and the Ports appear in Device Manager without any errors (Errors are indicated by a yellow exclamation mark).

  • Perform a loopback test: A loopback test will confirm that your card is able to Transmit and Receive Data. The Transmit and Receive lines will need to be connected so that any data sent out of the card is then received back on the same Port. Please use the Brainboxes Loopback Test Application to perform a loopback test.

  • If a loopback test passes, please contact Brainboxes Technical Support
