Hi all, The pinout is known and I have run the unit for a couple weeks at the +15V and +24V levels which is what the mainframe it came out of supplied. I'll just end up 3 terminaling to get the +15 from the +24. Just hoped there were some specs floating around out there! On another subject I will be adding some more to the quartz oscillator short term stability list I posted last year. A couple FTS1200 with accelerometers + a few more misc. oscillators.
