1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your EVAWGIB Mini Barcode Scanner Module. These modules are designed for integration into various systems requiring efficient 1D and 2D barcode scanning capabilities, including mobile payment applications.
The EV-X series offers different models with varying scanning technologies and interfaces:
- Laser Scanners (e.g., EV-X620): Can scan 1D barcodes from paper. They cannot scan barcodes from screens due to the nature of laser light reflection.
- CCD Scanners (e.g., EV-X720): Can scan 1D barcodes from both paper and screens.
- CMOS Imager Scanners (e.g., EV-X821T, EV-X921T, EV-X922T, EV-X931T): Can scan both 1D and 2D barcodes from paper and screens. These models use advanced image processing algorithms.
Please identify your specific model to ensure you follow the correct instructions and understand its capabilities.
2. Safety Information
To ensure safe and proper operation, please observe the following precautions:
- Do not stare directly into the scanner's light source (laser or LED) as it may cause eye damage.
- Keep the device away from water, moisture, and extreme temperatures.
- Avoid dropping or subjecting the device to severe impact.
- Do not attempt to disassemble or modify the scanner. Unauthorized modifications can void the warranty and pose safety risks.
- Use only the provided cables and accessories.

5. Setup Instructions
The scanner is designed for plug-and-play operation. Follow these steps to connect your module:
- Identify your interface cable: Your module will come with either a USB, RS232, or TTL cable.
- Connect the cable to the scanner module: Ensure a secure connection.
- Connect the other end of the cable to your host device:
- USB Interface: Plug the USB connector into an available USB port on your computer or host system. The system should automatically detect and install the necessary drivers.
- RS232 Interface: Connect the RS232 connector to a serial port on your host system. You may need to configure the serial port settings (e.g., baud rate 9600) in your application.
- TTL Interface: For TTL connections, refer to the wiring diagram below for proper pin assignments (TXD, RXD, GND, VCC 5V). Ensure correct voltage supply.
- Power On: Once connected, the scanner should power on. An LED indicator may light up, and a beep might sound to confirm readiness.
6. Operating Instructions
Using your EVAWGIB barcode scanner module is straightforward:
- Positioning: Place the barcode within the scanner's field of view. For optimal performance, ensure the barcode is flat and well-lit.
- Scanning:
- Auto-Induction Mode: The scanner will automatically detect a barcode placed within its scanning range and initiate a scan.
- Continuous Mode: The scanner continuously emits its light source, ready to read any barcode that passes through its field.
- Confirmation: A successful scan is typically indicated by a beep and/or a flash of the LED indicator. The decoded data will be transmitted to your connected host device.
- Scanning from Screens: For CCD and CMOS models, hold the scanner over the barcode displayed on a computer monitor, smartphone, or tablet screen. Adjust the angle and distance slightly if needed to achieve a successful read.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | Loose cable connection, no power from host device. | Check cable connections. Ensure host device is powered on and providing power to the USB/serial port. |
| Scanner does not read barcodes. | Incorrect barcode type for scanner (e.g., 2D barcode on 1D-only scanner), barcode damaged/unclear, incorrect distance/angle, interface not configured correctly. |
|
| Scanned data is incorrect or incomplete. | Poor scan quality, incorrect data format settings on host. | Ensure a clear scan. Check host application settings for data input format. |
| Scanner reads slowly or intermittently. | Environmental interference, dirty scanner window, low light conditions. | Clean the scanner window. Ensure adequate lighting. Minimize electrical interference. |
9. User Tips
- Interface Selection: The scanner's capacity (e.g., data transfer speed, compatibility) depends on the chosen interface type (USB, RS232, TTL). Ensure your host system supports the selected interface.
- Quantity: The product is typically supplied as a single unit (scanner module + cable + manual).
- Long 1D Barcodes: If you frequently scan 1D barcodes longer than 3 inches, a Laser scanner might be easier to use than a CMOS imager due to its linear scanning nature. However, CMOS imagers are more versatile for 2D codes and screen scanning.
10. Maintenance
- Cleaning: Use a soft, clean, lint-free cloth to wipe the scanner window. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use harsh chemicals or abrasive materials.
- Storage: Store the scanner in a cool, dry place, away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or twisting the cable excessively to prevent internal damage.
11. Warranty and Support
EVAWGIB products are manufactured under strict quality control standards. For any technical assistance, troubleshooting beyond this manual, or warranty inquiries, please contact your vendor or the manufacturer's customer support. Keep your purchase receipt as proof of purchase.
