send to the Access Control System. To support your proprietary Wiegand

format in a Pass-Thru mode, the following is required:

 Wiegand data is interpreted as a standard binary representation (i.e.

hex and other data interpretations are not supported)

 A contiguous series of bits for the ID number

 The sequence must be non-encrypted

 The Total number of bits in the format is 64 or fewer

 The bit stream provides the bits in order from Most Significant Bit (MSB)

to Least Significant Bit (LSB)

The V-Smart reader shall be unable to correctly generate the Card ID

required by the Access Control System if the conditions above are not met. If

your Wiegand format meets these requirements, then the following

information is required to configure this format into the V-Smart reader in Pass-

Thru mode:

 Total Number of Bits in the format

 Start bit position of the ID number data in the format (note: Bioscrypt

considers the first bit position as 0)

 Length of the ID number data in the format (number of card id bits)

13.5. Pre-Defined vs. Pass-Thru Functionality

Advanced Wiegand functionality shall be available for use on a V-Smart

when a Pre-Defined or Custom format is used that shall not be available for

Pass-Thru formats. Since Bioscrypt has intimate knowledge of Pre-defined and

Custom formats (including site code start and length, parity bit start and

length, parity bit calculation, etc.), the following features are available for

Pre-Defined and Custom formats:

 Alt Site Code: an alternate site code may be activated and selected.

This code shall act as the site or facility code required by the Access

Control System for access for successful authentications. When this

option is not selected, the V-Smart shall generate and send a site code

of 0. If a Wiegand sequence was provided and stored on the smart

card during the enrollment process, the Alt Site Code field should not

be selected so that the reader may instead pass through the site code

as provided by the Wiegand sequence.

 Fail ID Code: a failure code may be activated and selected. This code

shall supersede the ID portion of the Wiegand string for all failed

authentications that occur at the reader. When this option is not
