1. Pengenalan
This manual provides essential information for the proper setup, operation, and maintenance of your Yunseity 125kHz T5577 Writable RFID Smart Cards. These cards are designed for use with compatible 125kHz RFID readers and access control systems.
The T5577 chip is rewritable, allowing for flexible programming and use in various applications such as sensor smart door locks, school or enterprise access control systems, and hotel room cards.
2. Ciri-ciri Produk
- Rewritable T5577 Chip: The T5577 chip is blank and requires programming before use. It can be erased and written over 10,000 times.
- Keserasian Universal: Compatible with 125KHz radio frequency identification devices (RFID) readers and access control systems that support the T5577 chip format, including 1386, 1326, and H10301 formats.
- Bahan Tahan Lama: Constructed from long-lasting, waterproof, and wear-proof PVC material.
- Saiz Standard: The card is the same size as a credit card, with a thickness of approximately 1.8mm (0.07in), making it portable.
- Aplikasi luas: Suitable for sensor smart door locks, school or enterprise access control systems, general access control, and hotel room cards.
3. Setup and Initial Programming
The Yunseity T5577 RFID cards are supplied blank and require programming before they can be used with an RFID reader or access control system. Data cannot be read from the card until it has been programmed.
- Acquire an RFID Writer: Ensure you have a compatible 125kHz RFID writer device. This product does not include an RFID writer.
- Prepare the Writer: Follow the instructions provided with your specific RFID writer to prepare it for programming.
- Program the Card: Place a blank T5577 card on the RFID writer. Use the writer's software or interface to input the desired data (e.g., card number, access code) and write it to the card.
- Verify Programming: After writing, use the RFID writer's read function to confirm that the data has been successfully stored on the card.

4. Arahan Operasi
Once programmed, the Yunseity T5577 RFID cards can be used with any compatible 125kHz RFID reader or access control system.
- Present the Card: Hold the programmed RFID card within the proximity of the RFID reader. The typical reading distance varies by reader but is usually a few centimeters.
- Tunggu Pengesahan: The reader will typically provide a visual (e.g., LED light) or audible (e.g., beep) confirmation when the card has been successfully read.
- Access Granted/Denied: The access control system will then process the card's data and grant or deny access based on its programming.

5. Penyelenggaraan
The Yunseity T5577 RFID cards are designed for durability and require minimal maintenance.
- Pembersihan: Wipe the cards with a soft, dry cloth if they become dirty. Avoid using harsh chemicals or abrasive materials.
- Storan: Store cards in a cool, dry place away from direct sunlight and extreme temperatures.
- Elakkan Bengkok: While durable, excessive bending or physical stress can damage the internal chip or antenna.
- Medan Magnet: Keep cards away from strong magnetic fields, which could potentially interfere with their functionality.
6. Penyelesaian masalah
- Card Not Reading:
- Is the card programmed? Ensure the card has been properly programmed with an RFID writer. Blank cards cannot be read.
- Is the reader compatible? Verify that the RFID reader operates at 125kHz and supports the T5577 chip format.
- Is the card presented correctly? Hold the card close enough to the reader.
- Is the card damaged? Inspect the card for visible damage.
- Card Not Writing:
- Is the RFID writer functioning correctly? Test the writer with another known good card if possible.
- Is the card placed correctly on the writer? Pastikan penjajaran yang betul.
- Gangguan: Avoid using the cards on or near metal surfaces, as this can interfere with RFID signal transmission and reception.
