Chapter 4 Handler Interface
4.1
Introduction
U2810D provides the Handler interface which can provide the control signals and the
comparison output signals. As described in table 4-1, the control signals include
/TRIG
(External Trigger signal), /IDX (Analog measurement completed signal), and /EOM (End of
measure and comparison data valid signal). The comparison output signals include /P1 , /P2 ,
/P3 , /AUX and /NG . Using these signals, the U2810D can easily be combined with a
component handler and a system controller to fully automate component testing, sorting,
and quality control data processing to increase production efficiency.
