Signal Output Mode
The handler interface has 2 signal output modes. Signals in each mode carry di erent
information.
Mode 1
Outputs overall results of comparison for all speci ed segments. Also, outputs
BIN sorting results for segments speci ed using
Mode 2
Outputs overall results of comparison for all speci ed segments. Also, outputs
results of comparison and BIN sorting for each segment. Results of BIN sorting
are represented in 4-bit code.
Mode 2 can be further divided into
depending on the type of triggering used. De nitions in output signals are
di erent in these mode. See Table 4-12 for details.
Signal Lines
Signals sent from and received by the handler interface can be classi ed into 3 groups as
follows:
De nitions of signals in each line vary depending on the mode (mode 1 or mode 2) used. See
Table 4-10 and Table 4-12 for details.
Comparator Output Signals
/BIN1 to /BIN9, /AUX BIN, /OUT OF BIN, /PHI, /PHO, /SREJ (comparator signal for mode
1)
/F1REJ to /F10REJ, DBIN0 to DBIN3(comparator signals for mode 2)
/FAIL(overall comparator signal)
/NO CONTACT(contact check fail signal)
Control Output Signals
/INDEX(analog measurement end signal)
/EOM(measurement cycle end or comparator data enable signal)
Control Input Signals
/EXT TRIG(external trigger)
/KEY LOCK(key lock signal)
Note
\/" before some signal names means those signals are negative logic
(low-asserted) signals.
