VIVOTEK Wiegand-converter AO-20W

The VIVOTEK AO-20W Wiegand Converter is a reliable interface device designed to convert Wiegand signals (26-bit or 34-bit) to RS485 communication, enabling seamless integration of Wiegand readers with RS485-based access control systems. Ideal for upgrading legacy systems or expanding access control networks, this converter ensures long-distance transmission up to 1200 meters on the RS485 side.

Advantages

Supports both 26-bit and 34-bit Wiegand input formats, configurable baud rates (9600 to 115200 bps), and features ESD protection and watchdog function for enhanced reliability. The compact ABS plastic housing and LED indicators (Power, TX, RX) simplify installation and monitoring.

Suitable for

• Integrating Wiegand readers with RS485-based access control panels
• Extending cable distances beyond Wiegand limits (up to 100m Wiegand, 1200m RS485)
• Compatibility with Anviz and third-party Wiegand readers
