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.
