HP-C-T focus issue

What version of PC-DMIS are you running? I am assuming "a new cmm" is a NEW CMM running the latest version of PC-DMIS?

I am not familiar with that camera, but this is what I found (but I am sure you have done your due diligence on this install).

To install the software and configure the frame grabber hardware, do the following:

Install the USB to Ethernet to USB communication cabling.
Copy and unzip the deva036usb software.
Connect the HP-C-T to the machine.
Open Device Manager. Look for Other Devices/Unknown device
Update the driver. Select Browse my computer for drivers and go to the directory where deva036usb was unzipped.
Verify there is a Deva36 USB Video Probe under Universal Serial Bus controllers in the Device Manager and that the status is that it is working properly.
Run PC-DMIS in Administrator mode.
Close PC-DMIS.
Configure the PC-DMIS frame grabber and camera settings. For more details, see the " Interface-Specific Options " topic.
Run PC-DMIS.
Confirm the live image view is working.​

If you switch to English language in PC-DMIS, does it work?

Fixed : I changed a db9 wire and it works now
