hardkey error in 800xa v5.1 and how to order it
Rcently we had an error on our system 800xa v5.1 indicating that hardkey could not be read and after we confirmed the error everything became fine.my question is hardkey (dongle) on usb port can be faulty ( is it imaginable that hardkey become faulty anyway? ) or maybe problem is because of USB port ? or if problem is due to dongle how we can order it? just by part number and and machine ID on dongle we can purchase it or not, something else we should know and mention to buy it?
i appreciate your kind consideration to this matter.thanks.
