Chapter 7 Handler Interface
7.1 Basic Information
The handler interface outputs signals to indicate measurement completed, bin sorting
judgments of the comparator function, and Go/No-Go judgments of the list sweep
comparator function. The handler interface also has an input for an external trigger
signal. Using these signals, TH2816B 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. Table 7-1 lists the
handler interface specifications.

7.2 Handler Interface Operation
This paragraph provides information, including a description of the interface signal
lines and their electrical characteristics, necessary to use the Handler Interface.
7.2.1 Signal line definition
The handler interface uses three types of signals, comparison output, control input
and control output. The signal lines for the Comparator Function and the List Sweep
Comparator Function are defined differently for comparison output and control output
signals. The following defines the signals when the handler interface Comparator
Function and the List Sweep Comparator Function are used.
7.2.1.1 Signal Line Used for Comparator Function
The signal definitions used for the Comparator Function are as follows.
 Comparison Output Signals:
/BIN1 - /BIN3
/AUX
/OUT
/PHI primary parameter high reject signal
/PLO primary parameter low reject signal
/SREJ secondary parameter reject signal
 Control Output Signals:
/IDX analog measurement completed signal
/EOM end of measurement and comparison data valid signal
