INPUT/OUTPUT CONTROL | FC 203B FRACTION COLLECTOR
input/Output COntrOl
Input/Output Control
Provides inputs for:
• remote start/advance and end by contact closure
• analog signal from detector for peak detection and
quantification
Provides outputs for:
• event mark on tube advance
• programmable on/off control of pump, recorder, etc.,
by contact closure
The user’s guide describes how to make the input and
output connections and how to set the programmable
output. The following table lists the functions of each pair
of contacts.
PAIR DESCRIPTION
1–2 Analog input from detector. Used in peak modes.
Pin 1 is signal (10–100 mV); Pin 2 is ground reference.
3–4 Input A. When activated by contact closure, fraction collector will
start a run or, if already in run, will advance to the next tube.
5–6 Input B. When activated, collection will end and indexing head will
return to home.
7–8 Output 1. Sends a 0.1 second contact closure at each tube advance.
Used to indicate an event on your recorder/data device.
9–10 Output 2. User programmable contact closure. Timing of this
contact closure is set in the Technical Menu (press EDIT 2). See
the user’s guide to learn how to set this option. The factory default
setting is “On after wait 1”.
Also, Gilson Serial I/O Channel (GSIOC) port allows full-
function computer control of the fraction collector. See
the user’s guide for details.
