Keyence SR-2000 Barcode Reader User Manual

1. Introduction

The Keyence SR-2000 Series 1D/2D code reader is designed for high-speed and long-distance barcode reading with a wide field of view and large depth of field. This device supports simultaneous reading of multiple barcodes and varying positions, which contributes to shorter cycle times and enhanced operational stability. Its advanced capabilities eliminate the need for precise barcode position control or frequent changeovers, making it suitable for reading codes on moving objects, such as those on conveyors or robotic transfer systems. The SR-2000 features a fully automatic calibration function, simplifying setup and ensuring stable code reading under diverse conditions without requiring expert imaging knowledge or additional external equipment.

2. Product Overview

4. Setup

1. Mounting: Securely mount the SR-2000 unit in the desired location. Ensure the reading window has a clear line of sight to the barcodes. Consider the wide field of view and long reading distance capabilities when positioning.
2. Power Connection: Connect the power cable to the SR-2000 unit and to a suitable power source. The device operates on Corded Electric power.
3. Data Connection: Connect the SR-2000 to your host system (e.g., Industrial Automation System, PC) using either an RS232 or USB cable, as appropriate for your setup.
4. Initial Calibration: Power on the device. The SR-2000 features a fully automatic calibration function. Allow the device to complete its initial calibration process. Refer to the detailed software manual for specific calibration steps if manual adjustments are required for complex environments.
5. Software Configuration: Install any necessary drivers or configuration software on your host system. Configure the reader settings according to your application requirements (e.g., symbologies to read, output format).

5. Operating Instructions

The Keyence SR-2000 is designed for straightforward operation:

1. Power On: Ensure the device is powered on and connected to the host system.
2. Positioning: Place the barcode within the SR-2000's field of view. Due to its wide field and long depth of field, precise positioning is often not required. The reader can effectively scan codes on moving objects.
3. Reading: The SR-2000 will automatically detect and read 1D or 2D codes. The read data will be transmitted to the connected host system via the configured interface (RS232 or USB).
4. Multiple Code Reading: If configured, the device can simultaneously read multiple barcodes within its field of view.
5. Status Indicators: Observe the status indicators on the device (if present) for feedback on power, read status, and errors. Refer to the full technical manual for indicator meanings.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your SR-2000 Barcode Reader:

• Cleaning the Reading Window: Periodically clean the reading window with a soft, lint-free cloth. If necessary, use a mild, non-abrasive cleaning solution. Avoid harsh chemicals that could damage the lens.
• Cable Inspection: Regularly inspect all power and data cables for signs of wear, damage, or loose connections. Replace damaged cables immediately.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage to the internal components.
• Firmware Updates: Check the manufacturer's website periodically for firmware updates. Applying updates can improve performance and add new features.

7. Troubleshooting

If you encounter issues with your SR-2000 Barcode Reader, consider the following troubleshooting steps:

• Device Not Powering On:
  • Verify the power cable is securely connected to both the device and the power outlet.
  • Check the power source for functionality.
• Unable to Read Barcodes:
  • Ensure the barcode is within the reader's field of view and focus.
  • Check the barcode quality; damaged or poorly printed codes may be difficult to read.
  • Verify that the correct symbologies are enabled in the reader's configuration software.
  • Clean the reading window for any obstructions or smudges.
  • Perform a recalibration if the environment or setup has changed significantly.
• No Data Transmission to Host:
  • Check the data cable (USB/RS232) connections at both the reader and the host system.
  • Verify that the correct drivers are installed on the host system.
  • Confirm the communication settings (e.g., baud rate for RS232) match between the reader and the host.
• Intermittent Reading:
  • Check for environmental factors like excessive ambient light or reflections.
  • Ensure the barcode is stable during the reading process, especially for moving objects.
  • Inspect cables for intermittent connections.

For persistent issues, consult the comprehensive technical manual or contact Keyence technical support.
