I have an LKB Superrac 2211 Fraction collector, for which the manual has been
I think I can figure out how to program it by playing with all the buttons,
but I need help with one of the electrical connections at the back.
I want to hook up the "event marker" pen of a chart recorder to the the
fraction collector, so that I can tell when a new fraction has been started.
There is a 25 pin connector on the back of the Superrac (labelled "External
INPUT-OUTPUT"). This 25 pin connector is the same as the one used on a
parallel cable on an IBM-compatible printer (ie DB25). I just need to know
the pin-out diagram of this connector, especially the 2 or 3 pins that connect
to the "event marker" or "fraction change" contacts.
Many thanks for any responses. (I hope I am not stretching too far the
definition of methods-reagents.)
