Wiegand Mode Rules

• Enter PIN-codes or Reason Codes on the Reader within 10 seconds otherwise the

tag code is discarded.

• The System allows 10 seconds each for the entry of the PIN-code and the Reason

Code in Tag + PIN + Reason Mode.

• If the Impro WRM expects a PIN-code and receives a number greater than 65535,

then the WRM assumes the number to be a tag code. The WRM discards the

previously read Tag for the current one and the WRM will still expect a PIN-code.

• If the Impro WRM expects a Reason Code and receives a number greater than

65535, then the WRM assumes the number to be a tag code. The WRM discards

the previously read Tag for the current one and the WRM will still expect a PIN-

code or Reason Code, depending on the mode.

• If the WRM expects a Reason code and instead receives a number in the range

100 to 65535, the WRM assumes this is an error. The WRM discards the entire

transaction, entering a new tag code starts the process again.

• If using PIN-codes and Reason Codes set the Impro WRM switches for Wiegand

26-bit, 37-bit, 40-bit and 44-bit, not Wiegand open format.
