Switching a Di Box

  First of all welcome to CE ! And i really like your way you're expressing your query.
  I would like to ask some questions, are you going to interface that switches with your arduino board? And from that switch you want to generate a logic which is replicant of the switch. Is that true?

  I wish to be able to use the digital outputs from an Arduino that eventually (by some device) make the contacts as show in the diagrams 😀
  
  The switch in the diagram is the logic that I've figured out from desoldering the physical switch.
  
  So yes replicate the switching functions by software that controls the Arduino.
  
  (The Di box itself uses a 9Volt battery & the Arduino gives out 4.88V according to my multimeter )
  
  Thanks for your quick reply - I hope I'm making sense!

  can you tell me in that switch common is Ground or VCC? As i think using one Transistor you can do this. either NPN or PNP depends on that common connection middle one.

  I'm not really sure what those mean, what's the difference between Ground and VCC?
• 

  Harshad Italiya

  You can Ground is common or zero volt and VCC is some positive voltage may be 3.3V or 5V

  Thanks for your help.
  
  I don't know how would I go about finding this out?
  
  I have the switch in front of me, unfortunately the actual box is not currently at my house!

  I'll post one circuit very soon that will make clear, what i understood.

  Thanks, look forward to it!

  @SilverWings:- Did you find that Middle Connection?

  Hi godfather, sorry for the late reply things have been crazy with Christmas etc.
  
  I won't have access to the box until the 10th of January. (As it's not at my house)
  
  What is it I need to do when I get access to the box, turn the device on and measure the voltage between the top pin and middle pin, and then bottom pin and middle pin etc. ?
  
  Thanks for your patience!

  Yes, You got it! By that way we have clear vision that what exactly they are doing in DI box.

  Fantastic, I'll get back to you round about the 10th.
  
  Happy New Year to you!
