Sorry, but I've never had to add a second emitter to a device. Not saying anything about God, but just was always able to find a much better solution. I guess I've just been lucky in never running into a situation where 2 were needed. I have had many where I was able to remove the second emitter and make the system much more reliable.

I guess I was just able to convince the customer on how to do it properly. Maybe my upgrade skills are better than yours??? (If you've ever put 2 emitters on 1 device, I guess they must be)
