      Jamie ParkerAug 30, 2025
      If you are getting a 'Communication ERROR (Timeout CTS-ON Check: CV SEND). Communication ERROR (Timeout CTS-OFF Check: CV SEND)' message on your Topcon Controller, it indicates a data transmission error to the measuring head CV-5000. Check the cable connections between the CV power supply unit and both the KB-50 and the measuring head CV-5000. If the problem persists, update the software for the KB-50, the measuring head CV-5000, and the CV power supply unit to the latest versions.
