SMD 989
– User Manual
Page 28 (105)
The following chart provides a list of the selections in the IP input configuration menu and a
description of setting.
Receive
Enabled
Disabled
This setting allows the user to enable or
disable the IP input stream for primary or
backup use or input to the modulator
Alias
Permits entry of friendly name or description
Routing Mode
Multicast
Unicast
Multicast
setting allows the unit to receive
multicast streams. Multicast streams
originate from the IP range 224.0.0.0
–
239.255.255.255.
Unicast
allows the unit to
receive unicast streams. Unicast streams
originate directly from a source device.
Destination IP
224.0.0.0
–
239.255.255.255
This setting is only available when receiving
a multicast stream. This address is the IP
address the source device is sending to.
Destination Port
0
– 65535
This is the UDP port the source device is
sending to. This is the only setting required to
receive a unicast stream.
Input Buffer Size
(KB)
10
– 600 KB
This setting determines how much data is
received before the SMD 989 starts
decoding. Increasing this value will allow the
SMD 989 to receive streams on networks
with high network jitter. Increasing this value
also increases the latency of the SMD 989.
IGMP Filter Mode
Exclude
Include
Used on networks supporting IGMPv3. If this
setting is set to
Exclude
any streams
originating from the user defined IP
addresses will be rejected. If this setting is
set to
Include
any streams originating from
the user defined IP addresses will be
received.
Note: IGMPv2 is used to join/leave multicast streams by default if no IGMP Filter addresses are
entered. If IGMP Filter Mode addresses are specified then IGMPv3 is used.
