Parallel communications without handshaking
Judgment results are output using JD01 to JD08.

T1: START signal width (1ms min.)
T2: Response time with respect to START signal (1ms max.)
T3: The image capture time differs depending on the camera that you connect.
Note
The JR01 to JR32 and JD09 to JD32 numerical calculations and
judgment results are not output.
Parallel communications with handshaking
1)
When you have set to output both numerical calculation results and judgment
results, the judgment is output first, followed by the numerical calculations. The
judgment output ends after the output of the last number set for judgment output.
Numbers not specified in the Numerical Calculation settings and numbers subject
to output control are skipped.
2)
Numerical data is output in sequence from the least−significant byte.
Negative values are output as two's complement only in the case that the output
data length is 32 bits; in the case of 16−bit or 8−bit data, overflow occurs.
