First you must have the "discrete" codes for your inputs. Once you have that discrete it is just a matter of copy and pasting it into you PCF. Remote Central has hundreds of discretes in the regular Pronto section files and most should work with the 3000.
To add a discrete.....
Double click on your button
From the button properties choose the actions tab
Click on the Add IR Button
Click on the View/Edit IR button
Paste your code into the box that pops up
Click on OK
That's it.
Tips..If it is a discrete code that you got from Remote Centrals file section, then PENG will change the code automaticaly because it uses a different format.
I had trouble getting the codes I copied to paste into the window, but if when I highlighted the code I started at the rear of the code and highlighted to the front of the code it worked the first time almost always.
Make sure when you highlight that you don't put and extra space at the rear of the code.
If a code is "dirty" PENG will not accept it.
Hope this helps..
