If your Designers Worksheet or Mouse does not work on your Expression 3 console, check the configuration of the external port. It is configured for Expression Serial Protocol by default, which operates at a different baud rate than a Mouse or Designers Worksheet.
To change the configuration of the External Port:
- In the Setup screen on your console, choose '6 - Options Settings'.
- In the Options Settings screen choose '12 - External Port'.
- Toggle the setting to Designers Worksheet (works for Mouse also).
