Cause

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.

Resolution

The Smart Card Reader needs to be connected to a terminal connection in RS-485 so it can be changed back to using Weigand mode. See the Entering RS-485 Programming Mode section in the Smart Card Reader Installation Guide for further details.
