IPAC2 Problem

[dugg8]

Hey guys,

I just finished my scratch build this weekend and I'm currently in the process of working all the bugs out on the software side. For a keycoder I'm using the Ipac2 and running a PS2 cable into a PCI card that has both USB & PS2 ports. Now I have it all setup and everything works great BUT when I go to do a move that requires pressing 3 buttons simultaneously (ie -  Zangief's spinning lariat) it only registers maybe 10% of the time. Anyone run into this problem?

Perhaps the pci card doesn't buffer properly?  Try in notebook or other text editor......many keys at once and see if the keys show up properly?

Good idea. I'll try that out.

your MOBO don't have PS2/USB ports ?

[dugg8]

The motherboard has USB ports only

I assume then that you only have the PS/2 cable?  The easiest solution is get the USB cable.  You can order it from Divemaster127.  He carries the Ultimarc line of products in the U.S.

I'd wager that the PS/2 ports on this PCI card are actually just a crappy PS/2 to USB converter dropped on the board and hooked to what would otherwise be another USB port given that it has USB already, and putting "real" PS/2 ports that don't require extra drivers on PCI is essentially impossible.  Most of these can't handle more than 6 button presses, and some handle even fewer.  I know Ultimarc specifically recommends against the use of such converters, especially since the IPAC can be a native USB device.

YES! I just dealt with this on the MKII machine I'm building. In my case, the key presses registered, but would only stay pressed for 1 second. So, doing a charge (holding a button down) wouldn't work.

Hoopz is exactly right. It had been a while since I bought a machine and I thought the ipac used for USB was a different style ipac so I ordered an entire ipac thinking there were USB ipacs and PS2 ipacs. When it showed up and I realized it used a PS2 to USB cable. lol. So, I have an extra ipac.

Betcha a dollar that PBJ posts and offers you $5 for the I-Pac...

Damn, that sucks. I was totally going to sell it to him. Off to the trash.
