o V-Stations communicating over the Ethernet port can only accept one

connection at a time

o V-Stations must not be assigned an IP address which is already in use or a

conflict will arise, causing communication errors on both devices

o If using Ethernet, an appropriate subnet mask should be set in VeriAdmin to

ensure proper broadcasting capability to all units on the network. For

example, a class C network (supporting up to 254 readers) should have a

subnet mask of 255.255.255.0. If multiple class C networks are being used within

the same network, the subnet mask should resemble the form 255.255.x.0

where x appropriately masks out the bits common to both network addresses.

o Broadcasting to all V-Stations on a network is accomplished in VeriAdmin using

UDP, a connectionless datagram protocol. This is not a reliable protocol, and

V-Stations will not respond to broadcast communications to verify proper

delivery of the message. This should be used as a convenience but not relied

upon as a guaranteed communication method. This is especially true if

packets are routed, like over the Internet.

Operational Issues:

o V-Prox Cards registered as Command Cards (enroll or delete cards) cannot be

used as user cards

o The V-Pass system requires a PC running VeriAdmin or compatible software in

order to enroll fingerprints
