Operating Instructions

The Waveshare e-Paper Display is designed for simple operation, primarily focusing on content refreshing via the ESL-Gateway-AP Base Station and the associated cloud platform.

1. Power On: The e-paper displays come with a built-in battery and are designed to be always on, displaying content without continuous power.
2. Connect to Base Station: Ensure your ESL-Gateway-AP Base Station is powered on and configured to communicate with the e-paper displays. Refer to the base station's manual for specific setup instructions.
3. Content Refreshing:
   • Content (images, text) is pushed to the e-paper displays through the cloud platform via the ESL-Gateway-AP Base Station.
   • Access the Waveshare cloud platform (e.g., esl.waveshare.cloud) using a web browser on a computer or mobile device.
   • Follow the platform's interface to upload and assign content to specific e-paper displays.
   • Once content is sent, the display will refresh to show the new information. This process consumes minimal power.
4. Viewing Angle: The e-paper display offers a wide viewing angle of nearly 180°, ensuring readability from various positions.

The Waveshare e-Paper Display requires minimal maintenance due to its robust design and low power consumption.

• Cleaning: Use a soft, dry cloth to gently wipe the display surface. Avoid using abrasive cleaners or solvents.

• Storage: Store the displays in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
• Case Protection: The ABS plastic case provides dustproof protection. Avoid dropping the device or subjecting it to strong impacts.

Troubleshooting

If you encounter issues with your Waveshare e-Paper Display, consider the following common troubleshooting steps:

• Display Not Refreshing:
  • Ensure the ESL-Gateway-AP Base Station is powered on and connected to the internet.
  • Verify that the e-paper display is within the communication range of the base station (typically 10-30m indoors).
  • Check the cloud platform for any error messages or pending updates.
  • Confirm the display's battery is not depleted.
• Content Appears Incorrect:
  • Re-send the content from the cloud platform.
  • Ensure the image or text format is compatible with the e-paper display.
• No Display at All:
