Configuration
Item
Default
Setting Description
Unit IP address 10.0.0.1
(transmitter) or
10.0.0.2 (receiver)
Enter a unique IP address that is valid for your network. The preconfigured default IP address allows for
easy configuration in closed environments. You can use a cross-over cable to connect directly to a PC.
Subnet mask 255.255.0.0 Enter a valid subnet mask for your network.
Gateway IP
address
0.0.0.0 Enter the IP address of the router if the unit is to establish a connection outside of the localnetwork. This
is typically used in a WAN environment. This field can otherwise remain empty (0.0.0.0).
Video
transmission
UDP Use the pull-down menu to select the means of transmission. Select TCP (Port 80) to send data through
a firewall. Select UDP for communication between local networks.
Multicast
streaming
Off Use the pull-down menu to select MPEG-4 for multicast streaming mode.
Besides a one-to-one connection between a transmitter and a receiver (unicast), the NET300 lets you
connect a number of receivers to receive the video signal simultaneously. This is achieved by
distributing a single data stream on the network itself to a number of receivers in a defined group
(multicast).
With a valid multicast group address selected in the Multicast Group IP Address field, the NET300
operates in multicast mode (data stream duplicated over the network).
When multicast streaming is turned off, operation resorts to unicast mode.
Multicast group
IP address
0.0.0.0 This is the multicast IP address. (Network hardware—such as switches, hubs, routers, etc.—must
support the multicasting protocol, IGMP.) This field sets PelcoNet to use the multicasting protocol, which
allows more efficient use of bandwidth. The IP range is 224.0.1.0 through 238.255.255.255.
Some IP addresses may be reserved for system resources. Contact your network administrator for more
information.
Multicast video
port encoder 1
60000 Enter the port address for the video encoder 1 MPEG-4 data stream.
Multicast video
port encoder 2
61000 Enter the port address for the video encoder 2 MPEG-4 data stream.
Multicast packet
TTL
1 Enter the number of hops for the packet to live. TTL stands for time to live. This setting defines the
lifetime of multicast packages in the network. If multicast traffic is to be transmitted over routers and
switches, this setting is important in adjusting the lifetime of the package to the requirements of the
network.
NOTE: Changing the IP address also affects the current browser connection. You will have to
reset the NET300 and enter the new URL to regain connectivity to the unit.
