This demo program is designed for CN1 ~ CN6. The user can install an OME- DB-24C into CN1 ~ CN6 of OME-PIO-D144. This demo will request the user to input a number K as following:

If the OME-DB-24C is installed in CN1 Æ key in 0

If the OME-DB-24C is installed in CN2 Æ key in 3

If the OME-DB-24C is installed in CN3 Æ key in 6

If the OME-DB-24C is installed in CN4 Æ key in 9

If the OME-DB-24C is installed in CN5 Æ key in 12

If the OME-DB-24C is installed in CN6 Æ key in 15

Then this demo program will test D/O of PA, PB and PC sequentially.
