16.4 APPENDIX E
– GPIO PORT
The 15 pin HD SubD
GPIO
connector on the back of the Genius Dfeatures four General Purpose inputs and four General
Purpose binary outputs. The inputs are polarised Optocoupler inputs, while the outputs are Open Collector outputs. They
can be used to send commands to the device and to carry out specific functions. The inputs feature polarized photo
couplers on each input and a 150 Ohm protection resistor is always installed in series inside. The maximum current that
can circulate on each photo coupler is 20mA. The voltage supplied between pin 9 and pin 1 is +5 V dc non-stabilised.
16.5 GP In connection via internal activation (Relay)
As shown in the diagram below, taking the tension from the
Fox’s GPIO port it is possible to polarize a photocoupler and
use one of the four GP Input available. Taking the +5 V from pin9 and applying it to the anode of an optocoupler and
then connecting the common katode (pin7) to the mass represented by pin1 it is possible to reach the function.
