Hi everybody,
our customer just reported some issues with our attendance terminal which is built on EMX. They have 12 pieces of our terminal and there was no problem for two months, but yesterday, 4 of our terminals displayed error message when performing some IO operation (almost at the same time!). I know only error code of IOException, which is -520093696, which should be “InvalidDriver”. Can anyone tell what this error code could mean? Today another 6 terminals came out and I have still no idea, what’s going on… Can there be any issues with SD card (we use Transcend 2GB SD). I will be greatful for any idea…
Thank you
Martin
