Tendzone TYCHO T 1212/CA - Manual (Page 16)

Notes: a 10 k resistance should be connected between PIN-13 and any of the RO 5~8 to switch the OC output to 12 V. As is
shown in the chart, PIN-13 outputs constant 12 V voltage; PIN-11 corresponds to RO 8 that outputs 0 or 1 according to the
changes of the matrix. Such level can be used to trigger another GPIO or other devices.
The following settings should be done on the PC after the GPIO is connected in accordance with the above methods:
