Matrix: How do I tirgger a matrix control using HCI (Host computer interface ) protocol can you

Use this custom command which willprovide you with a table of GPIO Control labels and their associated Card/pinnumbering .
enter the card/pin number in to the HCI command line

Go to diagnostic > event log > request info >custom Message code = 56 Param # 1 = 6 Hit send

Trigger the lowest card/pin number Example for CTOO1 – trigger card/pin 28 pin 6

BTW use custom 56.5 To output the physical GPIOs &
custom 56.6 outputs the virtual Controls - Card/pins
