C005383_10 CR80XX Integration Guide
Notes:
1. Maximum image size.
2. Trigger must be asserted for Trigger Confirmation Time;
3. Trigger Confirmation Time defaults to zero and is adjustable as referenced above (register E3).
4.11 – Image Capture and Decode Timing Diagram
Image acquisition and decoding can be started from either the nTrigger line
(CR8011 or CR8012) or via a communications channel command. The
time required to capture an image can vary depending on the size of image
selected, the confirmation time register (0xE3), and where the imager is in
the capture cycle. The time to decode an image can depend on the image
quality, complexity of the barcode, etc. The maximum time spent trying to
decode an image defaults to 320ms and can be controlled by a register
(2C). To get more information on register functions, refer to the Interface
Configuration Document (ICD), available on the Code website (www.
codecorp.com).
