If placing units on a RS-485 network, you will also need to set up the
computer for RS-485 communications.
a.
Connect the RS-232/RS-485 converter to the PC’s COM port (must
support Send Data – a means of automatically sensing data sent
from the RS-232 port – we suggest the B&B Electronics,
, model 485TBLED or equivalent).
b.
Run category 5 rated cable from the converter to the first reader in
the daisy chain.

V-Smart considerations
a.
The V-Smart does not require an RS-485 network. There is no need
to distribute templates because the templates are carried by the users
in the cards.
b.
One security aspect of the V-Smart is that a site key is used to
secure the information on the smart card. If a card is presented to
the V-Smart it uses the programmed site key to unlock the data from
the card. The V-Smart is shipped with a default site key (a blank
field). If the programmed site key does not unlock the data from the
card, the user cannot verify their fingerprint. This provides system
administrators with a means to further protect their facilities from
unauthorized access.
c.
If the system administrator wants to periodically change the site key
(to further minimize the risk of compromised or lost cards), then this
can be done through an RS-485 network or by making the
appropriate changes to the reader through the Aux port.
