post #1 of 7
Thread Starter 
Hi Just starting to build a pc and I'm about to connect to Aquacomputer 5 controllers up to MB usb2 ports just wondering what the difference between KEY and N/C is. Does it matter if i plug a AC 5 controller in to pins 1-3-5-7-9 v 2-4-6-8-10 redface.gif

Pin Name Description Port
1 VCC +5 VDC USB 1
3 D0- Data -
5 D0+ Data +
7 GND Ground
9 key
2 VCC +5 VDC USB 2
4 D1- Data -
6 D1+ Data +
8 GND Ground
10 N/C

Im guessing N/C stands for not connected or something lol...

If they are both USB headers then I see no reason why you shouldnt plug USB devices into them.

Go for it.

Sorry should probably rephrase that question does the 'Key" pin affect devices in any way does it matter if my AC 5 is connected or not?

O and yes N/C is where there is no pin wink.gif

n/c means no connection, but there will be a pin present. a key will not have a pin present and the connector (if using a 2x5 usb connector) will be plugged (filled in) making it impossible to plug the connector in in the wrong direction

if you are using single usb internal connectors (1x4), then one connector will go on 1/3/5/7 and the other will go on 2/4/6/8

neither will use the key or the n/c pin positions
