Mark, I agree. I tried scoping some pins. I see a few different levels and one pin has what looks like a clock signal with a period of about 4.2ms. Other than that, hard to tell without a manual.
I know people went so far as to contact Perkin Elmer without luck, I had heard they had acquired EG&G. I wouldn’t mind sending one to someone that could do a better test on it. I’ll play around with them if and when I get the TPLL setup working. > On Nov 30, 2017, at 9:39 PM, Mark Sims <[email protected]> wrote: > > I doubt that it would be a direct mapping to a 9-pin serial connector.
