Multicast Address Setup Window
RX Port Field
The RX Port field identifies the port number for each line. The port number must be unique, per line, and must be greater than
1054.
Based on the entries shown in Figure 93, any console attempting to transmit to line 1 must have a Multicast Address of
225.8.11.81 and an RX port number of 2054 to monitor RX audio and a TX port number of 4072 to monitor TX audio.
TX Mcast Address Field
TX Mcast (Multicast) Address field identifies the broadcast address for all audio traffic transmitted on a specific line. All
consoles must have the same Multicast Address. The entry in the second Multicast Address field applies to the port number
entered in the TX Port field.
NOTE:
IP-223s can also operate Unicast (point-to-point), these fields can support class A, B, and C addresses.
NOTE:
Make sure the RX and TX port numbers are unique.
The range for this field is 224.0.0.2 to 239.255.255.255.
TX Port Field
The TX Port field identifies the port number for each line. The port number must be unique, per line, and must be greater than
1054.
Example:
Based on the entries shown in Figure 93, any console attempting to transmit to line 1 must have a
Multicast Address of 225.8.11.81 and an RX port number of 2054 to monitor RX audio and a TX port
number of 4072 to monitor TX audio.
TX Group Port Field
The TX Group Port field is used to transmit to multiple IP-223s based on a unique port number.
TTL Field
The TTL (Time-To-Live) field identifies the number of routers the multicast audio packets go through before being stopped.
Your specific network design dictates this value. If audio is not reaching a particular node on the network, increasing this value
may correct the problem.
The range for this field is 1 to 128.
