Networking Overview
Note: This section is an overview of networking parameters as they relate to the V1500. You will find detailed
information in the Network Module section of this manual.
Video is not transmitted on the Ethernet cable. Standard video transmission media is required.
Vicon’s V1500 Control System incorporates network communication using Ethernet, a standardized method
of connecting computers on a local area network (LAN). The V1500 system is Ethernet 10BASE-T or
100BASE-TX ready, which means it uses twisted-pair cable or two-pair CAT5 twisted-pair cable, respectively.
Using the network, you can connect multiple V1500CPUs so that CCTV equipment connected to one
V1500CDU may be controlled by other V1500CPUs. Wide area network (WAN, defined as two or more LANs
connected through routers), support is provided by the V1500. By expanding from the V1500 LAN to wide
area networks, you can connect multiple sites to the V1500 system.
The V1500 system uses standard Internet Protocol (IP) addressing for network communication. Each device
(V1500CPU,
V1500CDU
, PC, printer, etc.) on a network must have a unique IP address. Devices in the V1500
system are identified by this IP address. The IP address is defined using the V1500 Configurator for
V1500CPUs and by setting DIP switches on the network card of the
V1500CDU
s. The 32-bit address format is
four numbers separated by periods, and each set of numbers must be in the range of 0 to 255. For
V1500CDU
s, the IP address is
192.168.xxx.yyy
where xxx and yyy are set using the two banks of DIP switches on the network card. Setting these DIP
switches is discussed in the Network Module section of this manual. The IP address of each network device
must be unique. If the
V1500CDU
IP address scheme of 192.168.xxx.yyy is not compatible with other devices,
then you must perform a procedure discussed in the Reference chapter to override the V1500 IP address
prefixes of 192.168 or change the IP addresses of the other devices and use the Vicon default scheme.
A second, common identifier is needed for all devices on the network. This identifier is known as a subnet
mask, and is the same for all devices on the network. The default
V1500CDU
subnet mask is:
255.255.255.0
If the V1500 system is expanded across a WAN, which will require the V1500 system to communicate across
networks, gateway addresses need to be defined. This gateway address provides entrance to another
network. Routers provide the gateway to other networks.
V1500CDU
s use a default gateway address of:
192.168.xxx.001
where the xxx portion of the address is defined using a DIP switch on the network card, discussed in the
Network Module section of this manual. If the
V1500CDU
default gateway address scheme of 192.168.xxx.001
is not compatible with your network design, then you must perform a procedure discussed in the Network
Module section of this manual to override the
V1500CDU
default gateway of 192.168.xxx.001 or change the
addresses of the network routes and retain the Vicon default scheme.
A WAN is needed if multiple V1500 sites are connected through a public network such as the Internet, or
through privately leased networks using T1 lines, for example. The V1500 equipment only communicates on
10BASE-T/100BASE-T Ethernet networks. In cases where various types of networks are connected, routers
are used to bridge the different network protocols. The figure below illustrates a basic system with two V1500
sites connected by a generic WAN. Each “local”, or “V1500” side of a router must be 10BASE-T/100BASE-T
Ethernet. The WAN side of the routers, shown as “a” and “b” in Figure 2, can be any type of connection
(ISDN, T1, modem, etc.).
