recommended). Pin 11 should be connected to Power GND and Pin 13
should be connected to +12 VDC power input.
6.3. Grounding
The V-Smart reader shall have various grounding requirements:
Power GND (Pin 11): the return for the input power supply. Pin 11 shall
be connected to the negative on the power supply. Refer to Section
6.2: Power Requirements for further details.
Wiegand GND (Pin 6): the reference ground for the Wiegand Data 0
and Data 1 interface. Pin 6 shall be connected to the GND on reader
port of the Access Control System. Refer to Section 8.3: External
Wiegand Reader and Section 8.4: Access Control System for further
details.
Signal GND (Pin 12): the reference for serial communications. Pin 12
shall be connected to the GND on the serial port or RS-485/RS-232
converter (dependent on communications protocol selected). Refer to
Section 7: Communications for further details.
Safety GND (Pin 15): protects the V-Smart (sensor and internal
electronics) from electro-static discharge (ESD) by providing a safe
discharge path to an earth ground. Refer to Section 8.2: Earth Ground
and Section 9.6: Fingerprint Placement: Lock, Drop & Hold for further
details.
7. Communications
The V-Smart shall include support for RS-232 and RS-485 serial communications. This
is primarily intended for use with a PC running the VeriAdmin software, which
allows for template management (enrollments, deletions, editions, distribution)
and reader configuration. If RS-232 and RS-485 communications are desired for
use with an application other than the VeriAdmin software, the BIO-SDK (Bioscrypt
Software Development Kit) shall be required to integrate V-Smart support into a
custom application. Refer to Section 11: VeriAdmin Management Software for
further details on the software features.
The V-Smart shall provide three serial communications ports:
RS-485 accessible through the pigtail (DB15)
RS-232 accessible through the pigtail (DB15)
RS-232 accessible through the bottom RJ11 port
