Pin 6 acts as the reference ground for the Wiegand Data 0 and Data 1

interface.

8.4. Access Control System

The V-Smart reader shall support Wiegand protocol output for connection to

an Access Control System (ACS). This system may provide advanced access

control features such as audit trails, user-defined access scheduling, anti-

passback, etc.

The V-Smart by default shall generate a Wiegand output sequence based on

the fingerprint template ID number, unless a Wiegand sequence has been

provided to the V-Smart reader during enrollment and stored on the smart

card. Please refer to Section 8.3: External Wiegand Reader for further details.

An 18 – 22 AWG cable should be used for this connection. At 18 AWG, a

distance of 500 feet is possible. For Wiegand output the V-Smart reader shall

require a homerun connection to the ACS using the following three

conductors:

 Wiegand Out Data 0 (Pin 1) connected to the ACS Data 0

 Wiegand Out Data 1 (Pin 3) connected to the ACS Data 1

 Wiegand GND (Pin 6) connected to the ACS reader power GND (0

VDC)**

The V-Smart reader shall by default have the Wiegand output activated for

Standard 26-bit Wiegand format. The reader shall support other formats. Refer

to Appendix B: Wiegand Protocol for further information.

**Wiegand GND (Pin 6) should be commoned to both Power GND on the

external Wiegand reader and Access Control System reader Power GND. Pin

6 acts as the reference ground for the Wiegand Data 0 and Data 1 interface.

8.5. Line Trigger

The V-Smart reader shall include a Line Trigger, a low-level signal that is

triggered following a successful verification. By default, this line shall be

inactive and must manually be activated through use of the VeriAdmin

management software provided with the reader. When the Line Trigger is

activated, the user must also specify the duration (in seconds) the trigger

should be set high. This source output is an open-drain drive capable of 50
