Hello,
I’m new on this forum, made some search but can’t find any answer…
We’re using k8090-VM8090 card in one of our kiosk projects, and we have some times a strange problem.
The 8090 card simply controls 12v led, wich indicate to the user if he can do or not an operation.
Sometimes, the card is stuck on one instruction… so the LEDs contected to her doesn’t work anymore.
Also it cannot be operated by the demo software either, it can’t connect to the board…
To get it back on operation, i have to remove the 12v power supply and the usb port connected to my computer.
Any idea why this problem on some cards?
I use approx 100 cards on different kiosk, but only a few cards has this problem…
Thanks for help!
