I quoted you and this moved....

With the IPAC, you can connect a keyboard to the 'IN' and connect the 'OUT' to the computer.  The IPAC will interleave keyboard use with switch contacts.  Automatically, without intervention.  The Keywiz will also allow a keyboard to connect to it, but it doesn't interleave.  It requires you to flip a switch to toggle between sending keyboard activity and sending switch contacts.  IMO, the IPAC addresses this better as it does it automatically.  With the keywiz, you have to flip a switch on the keywiz everytime you want to use a keyboard.  The keywiz method does allow a few additional inputs due to this method, but if you are not needing more than the 28 that the IPAC allows, then this issue is moot.

Cool I didn't know that. But then I've only done minimal research on the i-pac. But what happens if you need to press both buttons on the keyboard and the control panel at the same time? Or should I just go with the USB type connector for the Ipac instead? Cause I really don't want one input to affect another one.

When would that ever happen?!? If for some reason, you just had to push the letter A on the keyboard and your buddy just has to push whatever button was mapped to A on the control panel - you'd hit the A twice and your cab would explode.

I believe that it will send which ever one is pressed first, then the other.  "The same time" is no more of an issue with keyboard button vs CP button as is CP button and CP button.  The keyboard sends a 'scan code' (which button is pressed) in about 1ms.  So even if you pressed a key on the keyboard and a button on the CP with the keyboard being slightly first, it should only delay the CP button press 1-2ms.  And that is only if you pressed them within 1-2ms of each other.  If you pressed the CP button 2 ms after the keyboard button, then the CP button would have no delay (from keyboard interleaving).  The keyboard does not require periodic 'scanning' or querying - it signals when it has data to send, and the host (IPAC) can choose to temporarily disable the keyboard from sending until it is ready.

Besides, what circumstances are you anticipating that have you using CP controls along with the keyboard?  (EDIT - lew beat me to it!)

zomg It'll explode!  :o

Well, I'm sure I'll be pressing on both during initial configuration setup and other test stuff. So what happens if I hold a button down on the keyboard then press a button on the cp?
