What kind of problem? If you have an older Prologix do a firmware upgrade. The designer (Abdul) and I have found out that the logic threshold on the Prologix is way too high. After some discussion it turned out that pull-up resistors could be engaged inside the uC in the Prologix. Not a perfect solution but that made it work with the HP3577. So Abdul changed the firmware and made that available. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Serisously I'd love to come to a SED get-together. (Are newbies invited too?) But I don't think I can afford the time or money to get to AZ. George H.
