5. Operating Instructions

This section outlines the basic operation of the RFID module.

5.1 Powering On

After connecting the power supply, the module will power on. The Indicating LED will illuminate, and the Buzzer may emit a short tone to confirm startup.

5.2 Reading RFID Cards

Present a 125 KHz RFID card or tag within 5 to 15 cm of the antenna coil. Upon successful reading, the module will typically provide an audible beep from the Buzzer and/or a change in the Indicating LED status. The data from the card will be transmitted via the data lines connected to J1.

5.3 Relay Output

The module features a relay output, which can be configured via the S3 Relay Output Selection. This relay can be used to control an electronic lock or other access mechanism based on successful card authentication.

5.4 Programming (Advanced)

While the module is designed for integrated systems, some advanced functions like adding or deleting RFID tags may require dedicated programming cards or an infrared remote control. These accessories are typically not included with the module and must be sourced separately if required for your application.

6. Maintenance

The Dioche RFID module is designed for low maintenance. Follow these guidelines to ensure its longevity:

Keep the module clean and free from dust and debris.
Regularly check all wiring connections for security and integrity.
Avoid physical impact or excessive vibration.

7. Troubleshooting

If you encounter issues with your RFID module, refer to the following troubleshooting tips:

7.1 Module Not Powering On

Check the power supply: Ensure it is providing 9-12V DC and is correctly connected to the J1 Main Connection Block.
Verify polarity: Incorrect power polarity can prevent the module from operating.

7.2 Poor Card Reading Sensitivity

Antenna Placement: Ensure the RFID card is within the effective reading range (5-15 cm) of the antenna.
Antenna Connection: Verify the antenna is securely connected to the J3-AJ3-B interface.
Environmental Interference: Metal objects or strong electromagnetic fields near the antenna can reduce reading performance. Try relocating the module or antenna.
Antenna Cable Extension: Extending the antenna cable significantly can weaken the signal and reduce sensitivity. If an extension is necessary, use shielded cables and keep the length to a minimum.

7.3 No Response to Cards

Card Type: Confirm that you are using 125 KHz RFID cards, as the module is designed specifically for this frequency.
Module Status: Check the Indicating LED to ensure the module is powered and operational.
