Potential fire hazard!! Be cautious!
I have been using IOcards for all my sim projects since 2004-2005. I love them and SIOC but,,,,,,, The last 3 out of 6 cards i have gotten have had issues and this last one VERY serious! USB axis card, wired it up, plugged in and was calibrating the card thru winxp, next thing you know, a bad burning smell followed quickly by by pc giving beeps for the usb plug and unplug warning. Looked down and the usb axis card was smoking!!! After some diag, found that BOTH my usb axis and usb output cards would arc and short out with the slightest movement of the usb cable where it plugs into the pcb. Very strange indeed and just wanted to warn you. By the way, the one that smoked, put in the freezer to cool it off, has worked perfect since as long as you don't touch the usb connection. I think it is cheap usb socket myself??
