How to test this circuit
October 14, 2021 - 6:26am

This is a very simple circuit to make but I am unsure on how to test it.  This is to transfer the push to talk signal to voice systems that use different voltages.  I was able to build the circuits easy enough but where they are to be implemented is over seas so I need to test them before sending them and I don't have the same equipment here that is in use there.  The voltage at pin 13 is 12V.

You need to different voltage sources or a spice simulator to simulate the circuit.

I have a 48v and 12v power supplies.  I'm not sure how to hook them up and what condition I should see at one end.
