What can I do if the USB connection from my PC to ctrlX SAFETY SAFEX-C.1x does not work?

You are happy since you unboxed your first ctrlX SAFETY SAFEX-C.1x controller,

  • you installed ctrlX SAFETY Engineering to your PC and
  • you powered the SAFEX-C.1x.
  • You connected it via your brand-new XACC-0-USBCx3M Engineering cable and
  • finally the USB connection does not work.

What can be the problem?

Hello dear ctrlX SAFETY users!

We received reports that there are combinations of PC and USB-cable where the USB connection between ctrlX SAFETY Engineering and the SAFEX-C.1x controller cannot be established, evein if the recommended USB Engineering cable XACC-0-USBCx3M of 3m length (comfortable work in the environment of the cabinet) is used.

The effective problem could not be analysed deep enough until today. It is only a small portion of environments affected.

Until we can provide an actual solution, there are the following workarounds:

  • Try to turn the USB-C connector at the SAFEX-C.1x side by 180 degrees into the opposite symmetric position.
  • Try to use a shorter USB cable of 1m length only or even shorter.
  • If you need the 3m distance, then try to put a USB-hub in the middle or use the USB-ports of a docking station.
  • If even this does not work, then try a different brand or type of PC. (There are indications about some HP computer models being affected.)

In any case, please let us know (the easiest, please reply here! Otherwise please contact your local Bosch Rexroth support technician or sales person!)

  • about the symptoms in your case and
  • the specification/type of equipment that does not work and
  • the specification/type equipment that solved the issue for you.

Best regards

Your ctrlX SAFETY team
