63
active bin comparison result output
signal is effective.
20
/PLO
The main parameter is lower: the low
active bin comparison result output
signal is effective.
21
/PIN
The main parameter PASS: the low
active bin comparison result output
signal is effective.
22
/SHI
The secondary parameter is higher: the
low active bin comparison result output
signal is effective.
23
/SIN
The secondary parameter PASS: the low
active bin comparison result output
signal is effective.
24
/SLO
The secondary parameter is lower: the
low active bin comparison result output
signal is effective.
25
/KEYLOCK
When this signal is effective, the keys in
the front panel are locked. Low active
signal is effective.
26
NC
Null pin.
27, 28
EXTV1
External power supply 1, the voltage
range: +5V~+30V.
EXTV2
and
EXTV1
are external power supply. When using
external power supply, they both must
be connected to the external power
supply, not just one of them.
29
NC
Null pin.
30
/INDEX
When AD data is conversing, the low
active signal output is effective.
31
/EOM
When the test finishes, this low active
signal output is effective.
32,33
COM2
The reference ground for external power
EXTV2.
34~36
COM1
The reference ground for external power
EXTV1.
37~40
NC
Null pin.
