1. Overview
The Y401WG-L is a point-to-point wireless Wiegand module for extending access-control signals over an RF link. A functional link uses a matched pair: one module connects to a Wiegand card reader, keypad reader, fingerprint reader, or facial-recognition terminal; the other connects to the Wiegand interface on an access-control controller.
The module carries the reader's D0 and D1 signals to the remote controller. It also provides two optional bidirectional I/O channels for compatible reader feedback and exit-button functions. The two modules use the same hardware and are not assigned permanent transmitter or receiver roles. The Y401WG-L does not replace a door controller, lock power supply, or lock-control system.
The paired modules transfer auxiliary I/O signals in both directions: either end can receive an input signal for the other end to output. These are low-current signal interfaces; check electrical compatibility before connecting external equipment.

5. Interfaces and Signals
Use the labels printed on the module when wiring. The module provides the following signal connections:
| Label | Function |
|---|---|
| +12V | Module power input |
| D0 | Wiegand data line 0 |
| D1 | Wiegand data line 1 |
| GND | Power and signal reference |
| IO1 | Auxiliary bidirectional I/O; used for buzzer or exit-button examples |
| IO2 | Auxiliary bidirectional I/O; used for LED feedback examples |
| USB-C | Virtual serial port for channel configuration and firmware work |
| SMA | Wireless antenna connection |
Before connecting equipment whose compatibility has not been confirmed, check the D0/D1 electrical requirements and the auxiliary I/O output type, input/output behavior, and interface compatibility with YenGear.
6. Installation and Wiring
See the user manual for reader-side, controller-side, auxiliary-I/O, and power connections. Shared supplies must meet both the module and the connected equipment ratings.
7. Channel Configuration
The modules automatically recognize Wiegand endpoints; both require the same wireless channel. Use the configuration commands and response examples in the user manual.
8. Important Notes
- Range figures assume an unobstructed line of sight. Walls, doors, metal structures, interference, and antenna placement affect the installed link.
- The module transfers signals; the access-control controller makes access decisions and controls the lock. Retain the required local exit and safety-release path.
- Install indoors, away from rain, condensation, and washdown. Firmware updates and custom functions require the supplied version's package and procedure.
