I-PAC keyboard error?
« on: October 29, 2002, 06:03:16 am »
When I plug in my ipac with no wires going into it and a keyboard plugged in, it works fine. The keyboard lights up and keystrokes are sent through.

So I wire the thing up, testing each key as I go until it is all working great, so I do a reboot. Still works. So I turn the power off and on again. DOH! I get a keyboard error.
It seems that the ipac does not get seen as a normal keyboard when all the wires are connected. Maybe it draws too much current or something.

Has anyone else had this problem, and how do you fix it?
I know its not a problem with the mobo 'coz I tested it out with my laptop as well.

Thanks

To be honest it sounds like you have the I-PAC wired incorrectly (such as at least 1 switch wired to the NC tab).  I would suggest using something like Keyscan instead of Notepad to check your wiring.

All the wires are connected properly, as I checked each switch and they all worked. I checked them with a multimeter and in DOS.

It all works fine if the unit has been initially powered on without having any switches connected and then gets wired up while still recieving power. It's just if you turn the computer off, when it comes back on it doesn't see the ipac as a keyboard anymore.

It is not an intermittent wiring fault as I the board has never worked if powered on when fully wired up. I am using a coin door, but they are only microswitches, just like the others, and they work fine as testing in dos demonstrated.

Could it be that the ipac is not getting enough current form the 5v off the keyboard connector. And if so, how can I give it more current without causing damage?

I really can't think of any other explanation as to why it should be seen as a keyboard when not wired up but then stop getting seen as one with all the wires in place.

Should I send it back for a replacement?

Thanks for your help.

Still seems like a wiring issue.  Or more a ground issue.  I would try it again with only one button connected to it.

but don't you get that error if you have a key pressed?  haven't tried it for a bit.  plug only your keyboard in and hold a key and turn it on.

I've seen similar posts like this on the Ultimarc message board.  Andy's response is almost always "Email me".  That's what I would do.
