Mine has the addition of the opto coupler in the path, not sure how that will affect it.
The results are in, doesn't work. I suspect whatever load/delay the optos inflict are the culprit. This is the version without the PIC, so it's not in the picture. This module just had the trigger go through the opto and on to the transmitter module. I see the pulse, but it doesn't ever trigger the receiver, I don't even see the LED on the transmitter flash at all. In an interesting twist, just connecting it that way to the transformer works a time or two, then it insists I power the board first and then trigger the transmitter.
