Hi, all,

My company has purchased a GQ-600+ -- it has not yet arrived, but I'm spinning up to connect it directly to a National Instruments cRIO computer, and access its CPM data using NI's rather unique programming language, LabVIEW.

LabVIEW allows connections to "raw" USB devices, so that the app programmer is responsible for implementing the command and response protocol. I can easily do that -- but to get the software and the device to rendezvous over USB, I need two hexadecimal codes: the manufacturer id and the product id of the 600+.

I've done a bit of searching, and have come up empty on this. Can someone help?

main CPU device of GQ-600+ don't handle directly the USB connection, there is a CH340C chip to make a 'USB' to 'serial com' bridge.
also the USB VID and PID references must be the generic one of the CH340C chipset.
to exploit the USB connection directly in RAW format, there will be a lot of work and requires mastering the operation of the CH340C chip.
It's easier to use the dedied generic driver and interface the GMC-600 + as a device connected to a serial port.

Mastery is acquired by studying, with it everything becomes simple
