WT/WR-7001     Wiegand® Code Interface   Click for larger image for  Wiegand Fiber Transmitter
For Industry Standard Wiegand? Applications  


The LiteLink® WT/WR-7001 system consists of the WT-7001 transmitter and WR-7001 receiver. Both units utilize digital encoding techniques to transmit and receive the Wiegand interface over a single optical fiber conductor.  The Wiegand interface industry standard, SIA AC-01 (1996.10), defines a commonly used interface between card readers and control panels used for Access Control, Security, Time and Attendance, and other related industries.

Both multimode and single-mode versions are available and installation is adjustment free. Integral LEDs are provided on both units to continuously indicate the presence of Data 0, Data 1 signals, and operating power making system troubleshooting simple.  The WCT-7001 also provides a regulated 5V DC output for powering access control devices
