Wiegand To RS232 Converter WG26/34
The SHARKBANG Wiegand converter accepts WG26/34 data and outputs via RS232. It is designed for access-control deployments that capture Wiegand card data and route it into legacy RS232 serial equipment or host controllers. The device focuses on straightforward data translation with support for common Wiegand bit lengths and reliable serial formatting. Its compact form factor makes it suitable for integration near door controllers or security panels, reducing cabling complexity. Practical for installations needing a simple bridge from Wiegand readers to RS232-based management systems.
Wiegand To RS485 Converter WG26/34
This SHARKBANG model bridges Wiegand data to RS485, enabling longer-distance serial transmission for access-control networks. It supports WG26/34 formats and provides reliable differential signaling via RS485, which is well-suited for noisy industrial environments. The converter is intended for applications where readers and controllers are placed far apart or across building infrastructure. It simplifies integration by presenting a clean Wiegand-to-serial path, helping to preserve data integrity across longer cabling runs.
FissaiD Wiegand To USB RS232/PS2/ABA
The FissaiD Wiegand converter supports 1 to 128-bit Wiegand data and auto-identifies bit length. It can operate as a Wiegand-to-serial RS232 adapter, a PS2/TTL/ABA converter, or a serial-to-Wiegand converter. With flexible output options including HEX, Decimal, or Raw Wiegand data, this device is suitable for projects that require seamless interfacing with various host systems, including Android, Linux, Windows, and iOS devices. It also functions as a professional Wiegand analyzer to interpret third-party reader data, aiding in troubleshooting and integration planning.
FissaiD Wiegand To USB RS232/PS2/ABA (USB)
This Wiegand-to-USB/RS232 converter from FissaiD also supports 1 to 128-bit Wiegand input with automatic bit-length detection. It can function as a Wiegand-to-serial RS232 interface or as a USB-to-Wiegand adapter, enabling broad compatibility with host devices and control systems. The product description emphasizes flexible output configurations (HEX/Decimal/Raw Wiegand) and the ability to pair with mobile or desktop environments. It is suitable for labs, security setups, and field deployments requiring versatile Wiegand translation to USB-based hosts.

The automatic direction control simplifies deployment and reduces the need for manual configuration, making it suitable for factory floors or secure facility networks that require reliable, scalable serial bridging.
XMSJSIY RS232 To RS485/RS422 Converter
The XMSJSIY converter provides flexible options to operate as RS232 to RS485 or RS422, with adaptive auto-switching and no jumper configuration required. It features zero-delay automatic transmission control, allowing smooth bidirectional data flow in mixed environments. The device supports passive and active signaling methods and is designed for durable operation in industrial settings where serial bridging is critical for access control or data collection systems.
Buying Guide
- Bit-length support and auto-detection: Look for devices that auto-detect Wiegand bit length (1–128 bits) to minimize manual setup and ensure compatibility with various readers.
- Interface and output options: Choose among RS232, RS485, USB, PS2, or TTL outputs based on your host controllers and existing infrastructure. USB adapters offer broad compatibility with modern systems, while RS485 is preferred for longer runs and noise resistance.
- Isolation and protection: Digital/isolation, surge protection, and ESD protection improve reliability in industrial environments and reduce risk of damage to equipment.
- Power requirements: Some converters draw power from the serial interface, while others include an isolated supply. Evaluate the need for additional power to the isolated terminal blocks.
- Direction control and throughput: Automatic RX/TX control helps simplify integration, especially in multi-device networks. Consider data rate support up to your required baud rates (bps).
- Physical form factor and mounting: Rail-mount and compact enclosures ease installation in security cabinets and equipment racks.
- Analyzer capabilities: Some models offer Wiegand analysis to interpret third-party device data, useful for troubleshooting and compatibility testing.
- Vendor support and documentation: Clear datasheets, installation guides, and example configurations help ensure a smoother deployment.
