Title: Keypad Help Needed - Num Lock
Post by: Freeplay on August 24, 2005, 07:00:10 pm

I'm looking at building my Jukebox cab with a keypad like this...

(http://www.jaycar.com.au/products_uploaded/productLarge_8684.jpg)

This keypad would be great for song selection etc...
I can redine keys etc... but the problem is the number lock key.
Does anyone know how to engage the number lock key... and then disable it.

I can bootup with number lock on... so I guess really I need to disable the key...
so people wonn't touch it and disable the number keys

This will solve a lot of problems if I can work it out.

Any ideas?.....

quick and dirty way would be to dismantle the unit and place something non-conductive (like paper) between the contacts on the sheets beneath that key.

Use this

and incorporate it in a batch file before you launch your jukebox software.

I used this solution with sk jukebox in my mame cab.

just keep in mind that with the software a user could still press the keypad and disable numlock.  It would be good for ensuring that numlock is on when starting your jukebox app though.

for your jukebox, would you use the other non-numerical keys too?  Like the / and the *, etc?

If not, remove all the keys you don't want to use, then mount the thing to something thin, like a metal panel, with just the number keys sticking through.

Thanks guys......

I will still need something more secure.

It isn't for commercial use.. but it is for parties... so i need to make it idiot proof

I just wrote some software for disabling the NumLock.  Unfortunately, I tested it on a keypad like yours and it didn't work because it operates independently.  The NumLock on my external USB keypad is not affected by the state of the keyboard NumLock nor is the keyboard affected by the external.  I think most external units probably power on with the lock on, so disabling your button would probably be your best bet.

Would a possible solution be to program your jukebox software to do the same thing if the Num Lock is active or inactive? For example, "up arrow" and "8" both scroll up.

Just a thought.
