VXDIAG VCX SE with license

For example Benz
This is a device with license. You can see Benz license.

VXDIAG VCX SE without license

It connects fine in vx manager.

Only PDU, Passthru and DoNET license.

No license device can only be used as a passthru device (tested working with Forscan, Bitbox, pcmflash etc 3rd party software programs).

If anyone wants to run OEM software, you run passthru and install the software, it (device without license) will give a license error.

Keep in mind you will definitely have to purchase a license.
