DD240XR High-Speed Digital Demodulator User Interfaces
MN-DD240XR – Rev. E 4-9
EXC REF CLOCK:
{1.000, 1.544, 2.000, 2.048, 5.000, 6.312, 8.448, 10.000
MHz} (This menu not displayed when Ethernet
interface is installed)
Rx Reference Clock Rate
This menu allows the user to specify the reference clock
rate. The rates are the most commonly used and
include T1, E1, T2 and E2 references. Not all terrestrial
interfaces include a Doppler buffer.
RX BUFFER SIZE:
Allows the user to specify the buffer depth. Enter in
1 msec increments from 00 to 64. A value of 0 will
disable, bypass, buffering and the demodulator will then
use the RX SAT as the clock source. Not all terrestrial
interfaces include a Doppler buffer.
TERR ETHERNET:
This menu is displayed when Ethernet interface is
installed. This interface supports MPEG over IP traffic.
This menu can be configured to support Ethernet Bridge
option or PRO MPEG COP3 option. Each option
supports different menu structures. The following items
are available under the Terrestrial Ethernet menu:
PROG ETH FLASH:
{PRESS CLEAR}
When Bridge option is selected, the PROG ETH FLASH
menu is the only menu displayed. The PROG ETH
FLASH allows the user to select the desired Ethernet
protocol option. The protocols supported by the
DD240XR are Ethernet Bridge or Pro MPEG COP 3. If
unit is configured for Bridge option, the user can activate
the PRO MPEG COP3 option by pressing the <Down
Arrow>. Once COP3 is reflected on the front panel,
press the <Clear> button to activate the option. The
front panel will display a sequence process indicating
that the flash is being Erased, Programmed, and
Verified. At the end of sequence the final status will be
displayed as either Successful or Unsuccessful.
THE FOLLOWING MENUS ARE DISPLAYED WHEN THE TERRESTRIAL ETHERNET
INTERFACE IS CONFIGURED FOR PRO MPEG COP 3.
TERR MAC ADDR: {0123456789AB}
This menu displays the MAC addresses of the Ethernet
Data Interface card. Entering any non-zero value in this
field will cause the EDI to use the entered value as its
MAC address.
Entering a value of all zeros will cause the Ethernet Data
Interface to revert back to its original MAC address.
