UDP Multicast
A multicast is a packet sent by one host to multiple hosts. In multicast, each host that belongs to a specific
multicast group will receive multicast packets for that group. To configure a host as a multicast receiver over
the Internet, it must inform the routers on its LAN. The Internet Group Management Protocol (IGMP) is used to
communicate group membership information between hosts and routers on a LAN. The NPort 5100A supports
IGMP version 2.
You could type the IP address (e.g., 239.1.1.1) of the assigned multicast group into the Destination IP address
column, after which the NPort will automatically add the Group and start receiving all packets from the group
in accordance with the multicast function.

The Pair Connection “Master” will contact the network host that has this IP address. Data will be transmitted
through the port No. (4001 by default). Note that you must configure the same TCP port No. for the device
server acting as the Pair Connection “Slave.”
