BioAdmin User Manual 184

BioEntry device is connected to the controller by ABA Track II output, not by

Wiegand interface, you should check Use ABA Track II. In that case, the output

signal will be in ABA Track II format. You can also specify the number of

characters for ABA Track II output.

 26 bit standard

The 26 bit standard format is most widely used and consists of 8 bit FC code and

16 bit ID. You cannot change the bit definition and the parity bits in 26 bit standard

format.

 Pass Through format

Pass Through format is used when only the format of ID field is known. When the

Wiegand input string is detected, BioEntry device extracts ID bits and starts

verification with the ID. If the verification succeeds, the device outputs the Wiegand

input string as unchanged. Parity check and advanced options are ignored in this

format. By definition, Pass Through format is only useful when the operation mode

is 1:1. If the mode is 1:N, the bits other than ID field are set to 0.

For example, assume that 32 bit Pass Through format is composed as follows:

XIIIIIII IIIIIIIX XXXIIIII IIIIIIIX (left most bit is 0th bit, BIT0)

I: Id field, X: Unknown field

You can configure this format in the following sequences.
