Connect and extend existing readers into a unified Wiegand access control system while keeping multiple authentication options available. Key benefits Broad compatibility: Bridges keyboard-style readers and Wiegand systems so you can reuse existing hardware and avoid costly replacements. Flexible security modes: Support for single-card, PIN, combined card+PIN, and multi-card/PIN configurations lets you tailor authentication to the level of security required. Centralized control: Works with standard Wiegand inputs to integrate readers with access control panels and controllers for simplified management. Master card support: Allows secure administrative operations such as enrollment or override without additional tools. What it does (functions) Converts keyboard-reader output to Wiegand-compatible signals or accepts Wiegand input for downstream systems. Supports keyboard/readers that use 4-bit, 8-bit (ASCII) or 10-bit virtual formats. Interfaces with readers or controllers that accept Wiegand 26 to 37 bits. Compatibility and technical highlights Keyboard formats supported: 4-bit, 8-bit (ASCII), 10-bit virtual — works with a wide range of keypad/keyboard readers. Wiegand input range: 26 to 37 bits — compatible with common access control panels and door controllers. Access modes: card-only, card OR PIN, card WITH PIN, and multiple cards/PINs. Administrative feature: supports master card function for enrollment, configuration, or emergency override. Practical scenarios Office access upgrade: Integrate existing keypad readers into a modern Wiegand-based controller to add centralized logging and scheduling without replacing installed readers. Multi-factor entry for sensitive areas: Require card + PIN for server rooms or records storage while still allowing single-card access for general areas. Parking or gated access: Connect vehicle gate keypads or remote keypad readers into a Wiegand entrance controller to unify visitor and employee credentials. How it helps you Saves cost by enabling reuse of installed keyboard readers and minimizing hardware changes. Provides flexible security options so you can apply stronger authentication only where needed. Simplifies integration with standard access control panels through Wiegand compatibility. Makes administration straightforward with master card capability for on-site management. Installation notes Designed to interface between keyboard-style readers and Wiegand inputs; connect according to the keyboard and Wiegand wiring conventions provided by your access control system. Verify the reader’s bit format (4-bit, 8-bit ASCII, or 10-bit virtual) and the controller’s Wiegand bit requirements (26–37) before installation to ensure correct operation. Supported functions (recap) Keyboard-reader formats: 4-bit, 8-bit (ASCII), 10-bit virtual Wiegand input: 26–37 bits Access modes: card, card OR PIN, card + PIN, multiple cards/PINs Master card function: supported This device provides a practical, standards-compatible way to extend and unify access control without replacing existing readers, while offering flexible authentication modes and administrative control.
