Let there be fire!!!
Okay, so I knew I had a bad opto amplifier board and I exchanged it for an aftermarket opto amplifier board, however, this made me feel as though I had 2 bad optos as well (at the ring)... so ended up picking up two new optos as well and everything has been right with the world.
Fast forward, now I want to get the fire ring mod, however as above, when I installed it with the above new aftermarket items it did not work. Bummer.
There is information on the 2-Niro website about the aftermarket boards, and it recommends reversing the top opto, however, when I did that, my optos didn't function at all, and therefore the mod would not work either. Double bummer.
So, because it had been a while since I had cleaned my game room shop, haha, after being asked if I still had the original optos, I dug into the trash and voila, I found them!
I first did a switch test, except this time I reversed the plastic on the top opto, and guess what, it worked! Note: This is something that is *not stated* on the websites that offer this aftermarket opto amplifier board when still using the original Stern optos, so this is also just a point of reference.
It was at this point that I checked my fire ring mod and guess what, it also worked! So I eagerly hooked everything up and now I am good to go with the fire ring!!!
So in summary, this fire ring mod will work with the aftermarket opto amplifier boards, however, it will not work with aftermarket optos. For whatever reason, it needed the original Stern optos (with the top opto plastic reversed on the new board), or I would assume a true transmitter and receiver (as most of the current day optos function as both). Go figure!
