    • Q
      qjenningsSep 1, 2025
      If you are getting a 'Communication ERROR (Timeout CTS-ON Check: CV THREAD SEND). Communication ERROR (Timeout CTS-OFF Check: CV THREAD SEND)' message on your Topcon Controller, it indicates a data transmission error to the visual acuity chart connected through the online system. Check the cable connections between the CV power supply unit and both the KB-50 and the visual acuity chart. Also, verify the serial port settings on the CV power supply unit for the connection to the visual acuity chart. If the issue continues, update the software for the KB-50 and the CV power supply unit to the newest versions.
