

QAM-256

Input Port

The input port that this SMDG uses.

Destination IP
Address

The IP address of the receiving device, based on the following
criteria:



If a GbE port receives the source, enter the IP

multicast address for the GQAM modulator.



If an ASI port receives the source, do not enter

data in this field.

Tip: When entering IP addresses, type a period to move
from octet to octet. Do 

not

 press the Tab key to move from

octet to octet; pressing the Tab key moves the cursor to
the next field on the window.

Destination UDP
Port
