Pins 9A through 13A (For D-SUB, pins 20 through 24) are used for switching channel automatically by

Pin 9A (For D-SUB, pin 20) is the most significant bit (MSB) and Pin 13A (For D-SUB, pin 24) is the least
significant bit (LSB).

1.7 Stage Number Output
Leak test stages can be identified from combinations of Stage # 0 and Stage #1.
Stage Stage #1 Stage #0 Stage #
WAIT, DL1 OFF OFF “0”
PCHK - CHG OFF ON “1”
BAL1, DL2, BAL2 ON OFF “2”
DET ON ON “3”
BLW - END Hold Hold
See NOTE
The stage # in which a Fail judgment is made, or a Stop signal is
received, is held from BLW through END stages (No output for a
Pass judgment). For instance, if a Fail judgment is made during
BAL2, the stage # in END stage is “2.” This makes sorting defected
parts easier.
