Product Details

  • The E.T. Box is a compact VPN router that can be mounted directly in the CNC machine’s control cabinet. It provides external access to the machine’s control via a LAN, WiFi or W4G connection.

Reduce down-time and cost!

  • Your Advantage: If there is a problem, a KNUTH technician will remote into your machine’s control within 4 hours and either solve the problem right then, or make targeted preparations for an on-site repair visit.
  • This is made possible via Flexy 205® by Ewon®

The E.T. Box will also give you new possibilities for doing more with your machine data!

  • Global access to your machine’s control
