Frequently Asked Questions
Q: What is the difference between Wiegand 26 and Wiegand 34 output on the S20X RFID reader?
A: Wiegand 26 and Wiegand 34 refer to the data format sent from the card reader to the access control panel. Wiegand 26 uses a 26-bit data packet and is the most widely supported standard, while Wiegand 34 uses a 34-bit packet, allowing for a larger number of unique card codes. The Asia-Teco S20X supports both formats, making it compatible with virtually all modern access control system boards.
Q: Does the S20X RFID keypad reader have a built-in relay?
A: No. The S20X is a "no relay" reader, meaning it outputs a Wiegand signal to your access control board, which then manages the door lock relay. This design keeps the reader installation clean and straightforward, and ensures that all locking logic is handled centrally by your controller — a best-practice approach for professional access control installations.
Q: How does the anti-duplication (anti-copy) feature work?
A: The S20X employs advanced RFID card authentication technology that verifies the authenticity of each card presented. It is designed to reject cloned or duplicated cards, preventing unauthorized individuals from using copied credentials to gain access. This is especially important in environments where security is a priority.
Q: Is the S20X suitable for outdoor installation?
A: The S20X is designed for indoor and semi-outdoor use. For fully exposed outdoor environments with extreme weather, additional weatherproof housing is recommended to protect the reader and ensure long-term reliability.
