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.
