4. Instruction of Handler Interface

In this chapter you will learn the following：
 Brief Introduction
 Operating Instruction

4.1 Brief Introduction

UTR2810E provides Handler interface，this interface is used for outputs sorting result of the instrument.
When the instrument is used in the automatic component sorting test system, the interface provides the contact
signal with the system and the sorting result output signal. As shown in Table 4-1, contact signal include /TRIG(start
signal)，/IDX(AD end of transition)，/EOM( end of all measurement)；Sorting result include qualified grade /BIN1,
/BIN2, /BIN3, auxiliary grade/AUX, and unqualified grade/NG.
Using these signal, the instrument can be easily integrated with the system controller into an automatic test system
for component testing, sorting and quality control, therefore improving the production efficiency.

4.2 Operating Instruction

4.2.1 Definition of signal line

HANDLER interface has three modes：Comparison output, control input and output.

Comparison output signal：
/BIN1，/BIN2，/BIN3，/NG，/AUX. Comparsion output signal generation see Figure 4-1.

Control output signal：
/EOM（end of measurement and comparison of valid data signals）

Control inutput signal：
/TRIG (external trigger mode)
Note："/"before signal name is presents that the signal is valid in low level.
