Abstract: A Wiegand Converter for generating a bi-directional data includes a Terminal Data Separator, a Switch Controller, a Bi-directional Switch to control the Input or Output Wiegand Data send through a Bi-directional Wiegand Data Line. The Received Data sent to Converter and Transmitted Data received From Converter are in recognized computer form such as ASCII. The unsecured Wiegand protocols can then be manipulated by a terminal or transmitted it via a secured form or different data communication protocols and reversed it back to an acceptable Wiegand form for controlling the devices to be located at remote sites or in separate compartments.
