That exceptionally long tooth time can't be right though. I seem to remember something like this happening before and I forget now what it was.

Phil,

I'll do that. But just as a first example, what I show above (with the log attached) is with 36-1 with both triggers single edge not inverted (however that last one might be misleading because it will depend on the input circuit used). And what would be expected is a single trigger 2 pulse at the first of the SecLevel Flag where there is the trigger flag. And there should not have been a gap in the trigger 1 pulse when the trigger 2 pulse occurred (and looking at the tooth time in the log, there should not have been one).

So looking at the log again, it does look inconsistent because there are 3 "1" in a row for trigger 2 when there is only a single trigger edge from the signal coming from the JimStim.

Actually, it is not inconsistent but rather should not be interpreted as an edge like trigger 1 but only as the signal being on.

See attached image. (EDIT... maths error was in my head). The highlighted area is where the display problem is happening.

I'm also still seeing some diagonal lines.
