3. Description of reading operation

DELAY

：

:The time from getting SYNC ON to reading

CHATT: The time for eliminating the chattering

IMAGE: The time for capturing an image

DECODE: The decoding time

DECODELIM: The maximum time for decoding

GOOUT: The time for outputting GO signal

NGOUT: The time for outputting NG signal

SERIAL: The time for outputting data through serial interface

3.1 Normal Mode

The SYNC input is turned ON by the single soft trigger (read start signal) then capture single

image and it decodes.
