3 Challenges Code Readers Face
1. Reader Cannot Be Mounted at Desired Distance: Difficulty in selecting the right reader and lens combination for specific distances, requiring systems to be designed around reader specifications.
"Selecting the right reader and lens combination for the distance is frustrating." "The system has to be designed to fit the specifications of the reader."
2. Optimal Settings Are Unknown: Issues with successful setup but frequent errors during actual operation, leading to lengthy and complex setup procedures.
"Reading was successful during setup but there are many errors during actual operation." "Setup requires a whole day."
3. Reading Fails Due to Glare: Problems with glare affecting readability, necessitating specific mounting angles or external lighting solutions.
"Do we need to mount the reader at a certain angle? What is the best angle?" "Is external lighting required? What kind?"
Diagram illustrating three common challenges for code readers: mounting distance, unknown settings, and reading failures due to glare.
1 Answer: Just Press the Button
The SR-1000 Series simplifies code reading with three core automatic functions:
⚙️ Autofocus
The reader can be mounted at any distance and maintain a clear image, with a maximum range of 1000 mm. This capability allows for flexible mounting and eliminates the need for precise distance adjustments.
⚙️ Automatic Tuning
Automatically determines optimal settings for exposure time, image processing filters, and other parameters, considering approximately 750,000 combinations to achieve the best reading performance.
⚙️ Automatic Polarization
Glare is automatically eliminated, removing the need for manual adjustment of the reader's angle or the use of external lighting. This ensures stable reading even on reflective surfaces.
Setting Complete.
World's First Automatic Polarization Control: The reader features both polarized and direct light sources. Automatic polarizing filter selection eliminates glare and allows for flexible mounting.

Advanced Capabilities for Reliable Reading
Autofocus: One Reader for Many Applications
Mounting is less restricted by reader performance or specifications, improving flexibility in machine designs for production lines and jigs. The autofocus capability allows a single reader to detect codes on targets of varying heights, secure robot movement ranges, and read extremely small codes.

Field of View 4x Larger: Comparison of conventional field of view versus the SR-1000 Series' wider field of view.
Diagrams illustrating the SR-1000's capability to read small codes (0.063 mm) at a distance of 110 mm, and its wider range (290 mm x 220 mm) and longer distance capability (1000 mm).
Automatic Tuning: Optimal Settings for Exposure Time, Filters, and More
The code reader automatically optimizes exposure time, image processing filters, and other parameters based on the target and mounting distance for clear image capture.
Correction Items and Examples of Affected Codes
Capture Brightness Correction: Automatically configures exposure time, dynamic range, and gain for optimal brightness.
Contrast Threshold Correction: Corrects black/white thresholds and optimizes contrast between code and background.
Filter Correction: Selects the best filter and intensity to correct the captured image.
Geometric Correction: Corrects distorted codes on cylinders or when the reader is mounted at an angle.
Image Reduction & Correction: Reduces image size to minimize background noise or missing spaces.
Visual examples of code correction for various issues like dark codes, low contrast, thin printing, distortion, and stray dots.
Latest Technologies Providing Stable Reading
High-Speed Search
2D Code Search in Captured Images: Binary processing enables immediate detection of 2D codes even if there are code-like patterns in the field of view.
Defective Code Positioning Program: Identifies the four corners of a 2D code using a similar detection pattern, significantly improving code detection performance.
Diagram illustrating 2D code search and the defective code positioning program's ability to identify code corners.
High-Level Decoding
Contrast Algorithm for Local Concentration (CALC): Divides codes into smaller pieces for binary processing, enabling accurate classification even with uneven print density.
Comparison of conventional technique versus CALC technique for code decoding, showing how CALC divides the code into segments for processing.
Smart Mode: Consistent Reading Regardless of Code Conditions
Fluctuations in code conditions are predicted during tuning, and expanded reading settings are automatically generated. This ensures stable reading even when code contrast changes, eliminating the need to reconfigure the reader. The reader predicts 43 patterns of change in printing conditions.
Diagram showing four patterns of code conditions: Thicker, Thinner, Darker, Lighter, illustrating how the reader adapts.
Code Quality Management (Custom Mode)
The SR-1000 can make judgments on code quality, detecting degradation before reading errors occur, enabling predictive maintenance of the printing process.
Matching Level Judgment Function: Differentiates between codes with identical reading rates based on a matching level score.
Code Verification Function: Verification based on code quality standards, supporting standards like ISO/IEC 15415 and SAE AS9132.
Diagram illustrating how the matching level differentiates between two codes with identical reading rates (e.g., Matching Level 75 vs. 43).
Easy-to-Use High Performance
Advanced Setup Software
The AUTODID NETWORK NAVIGATOR SR-H4W software provides easy code reader setup and reduces man-hours for preliminary tests. It supports connection via USB for the SR-1000 Series.
Key Software Functions:
Monitor: View the field of view to adjust code position.
Autofocus: Focus is adjusted automatically.
Tuning: Automatically selects from approximately 750,000 parameter combinations and polarization filter settings.
Advanced Settings include: Image Capture Range, Polarization Filter, Target Bank, Tuning History, and Number of Codes for Reading.
Tuning Monitor: Displays optimum settings determined from image processing filters and brightness levels.

Ethernet Communication Wizard
Setup is completed in four steps with visual explanations, eliminating the need for users to understand all settings. This wizard simplifies communication setup.
Wizard Steps:
Trigger Settings (I/O input, command input)
Read Data Destination (Field network, PC)
Communication Protocol (EtherNet/IP™, PROFINET, TCP, UDP, or PLC link)
Advanced Settings (Detailed setting for each protocol)

Sophisticated Measurement Modes
The SR-1000 Series offers pre-verification and measurement of allowable line speed for reading codes at high speeds.
Reading Rate Measurement
Measure the reading success rate without conducting tests on multiple targets on the actual production line.
