STU-430G / STU-430V difference

Q: What difference is there between the STU-430G and STU-430V?

The 430G and 430V are identical in appearance and size and resolution - the only difference is the way in which they communicate with Windows.
The standard 430G operates as a normal USB device and appears as such in Device Manager.
The 430V is configured to operate as a serial device via a virtual COM port - see the Device Manager screenshot extract below.
The advantage of this is that the 430V can be forwarded over an RDP session to a remote server without the need for any additional USB forwarding software, thus reducing expenditure.

If you want to use the 430G over RDP you must install third-party USB forwarding software because RDP cannot handle the pen data on its own.

NOTE:

The 430V can be converted to operate as a normal USB device (i.e. as a 430G)  by running "serial2hid" as explained in this FAQ:  STU Serial Connection – Developer Support (wacom.com)  but the 430G cannot be changed to serial.
