Standard specifications state that a maximum Wiegand communication run not exceed 500 feet. Beyond such distances reliability concerns arise. When circumstances dictate a long cable run between control panel and reader, exceeding the 500 feet guideline, rely on Keyscans WIEEX2 Wiegand Extender. This device converts the Wiegand single to standard RS485 providing a communication range of up to 2000 feet between WIEEX2 receiver and WIEEX2 transmitter while using standard CAT 5 cable between units. The standard RS485 output opens up a host of other design options such as RS485 to fiber optic modems and other mediums for transmitting the reader data if electrical isolation over long cable runs are desirable.
