2. Inputs Tests

This is a read only sequence in Power Up Programming, that is, there is nothing to program into memory.

This sequence gives you a read out on the LCD of any Input that is currently on, a test and diagnostic tool for all of the wiring and programming that you have done to this point. An aid in setting firing points for keyboards, the LCD will read out the pin number at the point of turning on. If there are inputs stuck on, you will see them displayed on the LCD, a quick way to get the inside picture of the total number on and the first one to fix.

Enter the Power Up Programming Sequence as instructed in Power Up Programming Overview. ‘Increment’ with key 3 to 2. Inputs Test and ‘enter’ with key 8. The LCD will start with address 0.

Any key that you depress will be displayed at the moment of switch contact, For example if you hold Key 9 only, it will say: “total on: 1 and high pin: 9”. The reason for saying high pin is that the LCD cannot display more than 1 pin, so the highest of any multiple of keys will be displayed. For example if you hold keys 9 and 10 down, the LCD will say: “total on: 2 and high pin: 10”.

Use keys 2 & 3 to change the address number which equates with the dipswitch setting, and again holding any input that is wired to this dipswitch address will display on the LCD.

Use great key 1 to escape or exit. The LCD will auto increment to 3. Division Naming.

NOTE: By default address 0 is assigned to be the Great division. Since the first 8 keys of the Great keyboard are the programming keys, they are ignored in this test, but hitting any key from #9 on will give an LCD readout of which key you are holding and the total number on that are being held.
