Does anyone have a schematic for the TR16?
I have one I just assembled but only channel one is working. I can see that the inputs to the other channel opto isolators are not getting pulled down so nothing is selecting the other channels. I have 2 24 port boards I built that work fine and swapping the 485 and zero crossing chips between boards do nothing. So either my pic is not working correctly or something else is unhappy. Looking for a drawing to see how the signals get around.
