DM240XR High-Speed Digital Modulator
User Interfaces
MN-DM240XR– Revision 12
4–14
JITTER TRACKING: {Widest, Wide, Mid Level, Narrow, Narrowest}
Allows the operator to select how the modulator reacts to and
compensates for jitter. Because the modulators transmit clock is
locked to the incoming data stream, care must be taken when
selecting this parameter. While wider tracking allows larger
changes due to network jitter to be compensated for, it also
means that the receiver will have to track larger, faster, clock rate
changes as the transmit clock is adjusted. On the other hand,
narrower tracking means smaller, slower, changes in the clock
rate but requires more precise network timing to keep the jitter
buffer from over or under flowing.
BACKUP MODE:
{Manual or Automatic)
The Backup Mode allows the user to utilize a backup IP
Address in the event the primary IP selection fails.
Manual Mode
: When selected, the modulator will stay with the
selected online port (Prime or Backup) even when it is not able
to lock to the incoming data stream. User must select with Prime
or Backup address in the ONLINE SELECT menu.
Automatic Mode:
When selected, the modulator will switch
between the Prime or Backup port when it is not able to lock to
one or the other.
BACKUP DELAY:
{100ms TO 5 seconds}
Allows selection of the time to delay in the event of an online
source fault (prime or backup) before switching over to the other
source (backup or prime). Entry is in 100 ms steps from 100 ms
to 5 seconds. Displayed when backup mode is set to AUTO.
PRIME ETHERNET:
Scroll down to configure the IP selection for the prime UDP port
PRIME IP ADDR:
{XXX.XXX.XXX.XXX}
Allows entry of the prime IP address to be used by the
Ethernet Data Interface. This will be the source IP
address for all Ethernet traffic generated by this
interface.
Multicast Mode
: requires that the IP Address entries
range from 224.000.000.000 to 239.255.255.255. When
unit is placed in Multicast mode, it will display the
Source IP Address and Unicast IP Address.
Unicast Mode:
All IP entries outside of the Multicast IP
Addresses will place the unit in Unicast mode.
PRIME UDP PORT: {XXXXX}
This is the destination UDP port on which packets
addressed to the prime IP address will arrive.
When operating in COP3 RTP FEC mode
