Figure 10: General settings for the reception ports (IP RX Common Settings)
If the network infrastructure is of redundant design and if “Data A” and “Data B” have the same
signal applied to them via a different supply line, the U 262 Gateway can be configured such that
in the event of a signal loss the active data port is automatically switched over (“Automatic” selec-
tion). If this redundant supply line does not exist, the “Static” option should be selected.
9 IP setting for transmission ports
NOTE:
The transmission ports should be configured in agreement with the network administrator in order
to ensure that no problems in the network occur!
Clicking on the “IP TX 1” to “IP TX 16” submenu takes you to the IP settings for the transmission
port.
9.1 Transmit port
The “Transmit Port” line can be used to select the port which is used to send the multicast
group.
A value ≥ 1024 should be set for this in order to avoid conflict with services (Port 21: FTP, Port
80:
http, Port 110: POP3 etc.).
9.2 Destination IP
The “Destination IP:Port” line is used to assign an IP address and a UDP port to the ASI trans-
port
stream converted according to IP. Usually, a multicast address is input here, since this allows
the data stream to be received by several IP receivers. By contrast, a unicast address can be
received only by one IP receiver.
Multicast addresses are in the IP address space 224.0.0.0 to 239.255.255.255, the range
224.0.0.0 to 224.0.0.255 being reserved for administrative purposes.
