Chapter 8 The description for
Handler (optional)
The
STB8827
provides the Handler interface for you. The interface is mainly
used for the output of the sorted result. The interface offers the communication
signal and the signal for the output of the sorted result. The separator
result is corresponding to the output of BIN 10. The design for the Handler
interface is very smart with the status of the output signal can be defined
according to your application target.
8.1Technical description
The following table shows the description for
STB8827
HANDLER.
The output signal:
low effective, open collector output, optoelectronic isolation
Output signal judgment:
BIN comparator: good, over the standard, not good
List sweep comparator: IN/OUT for every sweep point and pass/fail for all the
compared result.
INDEX: AD Conversion ended
EOC: end of one test and comparison
Alarm: alarm for circuit interruption
The input signal:
optoelectronic isolation
Keylock: lock the keys on the front panel
External Trigger: pulsewidth

8.2.1 The definition for the signal line
The Handler interface has 3 signal lines: comparison output, control output
and control input. The signal line’s definition for the BIN comparison or list sweep
comparison is below:
Comparison signal lines:
Comparison output signal
/BIN1 - /BIN9, /AUX, /OUT, /PHI (the main parameter is higher), /PLO (the
main parameter is lower), /SREJ (the secondary parameter is not good). The
signal line distribution for comparison out is shown in the figure above.
