1. General Introduction

This converter was developed to interface access control system. It has 4 channel of Wiegand input and output interfaces with a 10M/100M Ethernet RJ45 port can be compatible for correspondence of TCP/IP communication. It can connect max four Wiegand RFID card readers interface to computer via TCP/IP network. And also can send card numbers from computer to access controller Wiegand input interface include of Wiegand 26bit, 34bit, 66bit or other Wiegand bit based on Wiegand communication. The controller working on DC9V to DC24V wide power supply, and provide a TTL communication interface for testing and upgrade the firmware to suit for some special project: for example to customize Wiegand format bit such as Wiegand 37bit, 48bit, and 60bit, etc. The device also has 4CH input interface to check relevant electric input such as LED indicator, buzzer, etc. It is really a good IOT Wiegand transfer device for access control.
