Veri-Series Setup Guide

5. 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,

www.bb-

elec.com, model 485TBLED or equivalent).

b. Run category 5 rated cable from the converter to the first reader in

the daisy chain.

6. 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.
