Appendix B – WIEEX2
Appendix B reviews general information, installation guidelines, and connection diagrams for Keyscan's RS485
Wiegand extender kit (WIEEX2). For doors/readers at distances greater than 500 feet/152 metres from the
access control units, which is the maximum Wiegand communication distance, the WIEEX2 extends the
communication range by up to 4000 feet/1219 metres. When installing the WIEEX2 extenders please check
the version and observe the corresponding wiring diagram. Each Wiegand extender – WIEEX2 – includes one
(1) transmitter and one (1) receiver. The following additional components may be required to complete the
installation:
 12VDC 1 Amp power supply with battery backup
 mounting interface enclosure
Important
Do not mix WIEEX2 (firmware 6.00 or higher) receivers and transmitters with previous generation or
WIEEX (firmware 5.03 or lower) receivers and transmitters.
