Welcome to the first Tech Tip of the Month from LAI Games! Every month we’ll send you a tip that will help you get the most out of your games. We hope you enjoy this new feature.

Input “Switch” test

Techtip1-1Are all my buttons working? Is the main board seeing the notch signal from the ticket mech? Do I have an active prize sensor board?

All these questions can be answered using the “switch test” mode that is common to most LAI games. This mode can be accessed by opening the front or coin door to your game and pressing the test button until your credit display shows a “C” in the first digit and a number, usually 0, in the last digit. If you have a number other than zero showing, then you have a stuck button, a prize sensor active or possibly a notch sensor signal coming back from your ticket mech. The following table is from our Stacker Standard manual. This table may vary from game to game. Refer to the manual for your specific game.





As you can see from the table above, you can test switch functions, you can test the notch sensor on your ticket mechanism, or you can see if a sensor board is active. You can test your sensor board by blocking the beams going through the prize box.

The input or switch test can be a very handy diagnostic tool. Next time you have the coin door open try it out. It’s one more weapon for your arsenal of trouble shooting tools.
