4.4 Connecting to the Part handler (Handler Interface)
4-16 ZM2371/ZM2372
Table 4
–3 Functions of handler interface signal
Pin No. I/O Signal name Descriptions
1 IN TRIG, /TRIG
External trigger signal (rising edge)
Can be switched into falling edge
26
IN
/RCL0
(low order)
Setting/correction value memory selection signal (Binary)
When /RCL-VALID is 1 (low level) and trigger source is
external (Ext): once the external trigger signal stated
above is received, the memory specified by this signal
allows the setting and correction value to be recalled and
measurement is conducted under those conditions. Recall
of memory number out of the range may result in an error.
2 IN /RCL1
27 IN /RCL2
3 IN /RCL3
28
IN
/RCL4
(high order)
4 IN (reserved)
Not in use Do not connect anything.
29 IN (reserved)
Not in use Do not connect anything.
5 IN /RCL-VALID
It shows that the memory selection signal is valid.
30 OUT /BIN1, /P-HI
/BIN1 to /BIN14: Bin sorting signal
/BIN10 to /BIN14 are output when Bin expansion is
enabled (besides the limit comparison is disabled).
/NC: Contact failure
/PHI: primary parameter upper limit over signal
/PLO: primary parameter lower limit under signal
/NC, /PHI and /PLO are output only when Bin expansion
is disabled (initial value)
/P-HI, /P-IN, /P-LO
：
Primary parameter
comparison signal When limit comparison
/S-HI, /S-IN, /S-LO
：
is enabled, Bin sorting
Secondary parameter signals of “/BIN1 to
comparison signal /BIN14”are output in
/IN: Primary/secondary total place of /PHI and /PLO.
pass comparison signal
Also for the limit comparison, /NC, /ERR, /OUT OF
BINS (signal where /IN is reversed) and /S-NG (/S-HI
or /S-LO) are output.
OUT /BIN2, /P-IN
31 OUT /BIN3, /P-LO
7 OUT /BIN4, /S-HI
32 OUT /BIN5, /S-IN
8 OUT /BIN6, /S-LO
33 OUT /BIN7, /IN
9 OUT /BIN8
34 OUT /BIN9
10 OUT - - - /BIN10
35 OUT - - - /BIN11
11 OUT /NC, /BIN12
36 OUT /PHI, /BIN13
12
OUT /PLO, /BIN14
37 OUT /OUT OF BINS
Fail comparison signal
13 OUT /INDEX
Signal acquisition end signal. Once it becomes “1” (low
level), it is possible to switch into next DUT.
38 OUT /EOM
End of measurement signal. Once it becomes “1”(low level),
the comparator result become valid and it is possible to
read.
14 OUT /ERR
Measurement error signal It shows excessive voltage or
current, contact failure(NC), ALC failure or other errors.
39 OUT /S-NG
Secondary parameter fail comparison signal
15 IN /KEY_LOCK
Key lock signal. Once it becomes “1”(low level), it disables
all key-operations of panel. It cannot be canceled through
the panel or remote control.
40 - - - (reserved)
Not in use. Do not connect anything.
16 to 20 IN EXT DCV
External DC power input (+5V to +24V)
21 to 25 IN EXT COM
External DC power input(common)
Each signal of handler interface is isolated from the case
and operates with the external DC power.
41 to 45 OUT INT DCV
Internal DC power output (+5V)
46 to 50 OUT INT COM
Internal DC power output (common)
To operate the Handler interface with the Internal DC
power source, make connection between EXT COM and
INT COM and also between EXT DCV and INT DCV. There
is no isolation with the case.
