When a card is presented at the Smart Reader it beeps but no card data is sent through to the Security Expert Controller. The Reader LED is flashing red then green every second continuously.
Security Expert Smart Card Readers which support both 125Khz and 13.56Mhz (SX-DRD-xx, SX-DRK-xx, SX-RK-xx)
The Smart Card Reader is not able to communicate with the Controller as it is in RS-485 mode but the connection being used is Weigand. Once connecting to the the Smart Reader in RS-485 mode the reader will not communicate if it is then connected up to a Wiegand port.
Once a Security Expert Smart Card Reader is used in an RS-485 configuration it will not work in Wiegand configuration until it has been re-programmed with a configuration card designed for that purpose. The configuration card (SX-ISO-CONFIG) must be purchased through Schneider Electric. See the Security Expert Credentials Order Form for details.
This is because RS-485 is a two-way communication, intelligent wiring protocol. Once the reader is set in this two-way communication mode there is currently no way, without the configuration card, to go back to a less intelligent one-way mode like Wiegand.
Note: Readers manufactured in 2017 or before may have a firmware version that uses a configuration mode that will not respond to a configuration card. If you contact Schneider Electric for a configuration card, supply the serial number (SN) from the back of the reader on your request.
