11.1 Main Rotation
11.1.1 MAIN ROTATION FOOTER
•
Reference : When PTP Mode is selected in the reference menu, the display in the Main Rotation pages indicates REF: PTP on
the left of the reference line with 4 different options to its right:
-
“Master: External”
-
“Master: Internal”
-
“Master: Internal / OCXO”
-
“Master: GPS Receiver”
As explained in 3.1 above, selecting PTP Mode in the reference menu means
that the DXD-8 will participate in the PTP Grandmaster selection (see 12.5,
Selecting a Grandmaster). If another unit is selected by the BMCA, “Master:
External” will be displayed in the reference line.
But, if the DXD-8 is selected, one of the other 3 options above will be
displayed: Internal, Internal / OCXO or GPS Receiver.
•
Lock Status : The bottom line of the display has the usual LOCK status, but in the case where the DXD-8 is the grandmaster,
when locked it changes to "LOCKED / GRANDMASTER”.
In case the DXD is or becomes a PTP Salve, when locked it changes to “LOCKED / PTP SLAVE”.
Note that, if another source was selected in the reference menu, such as Video Sync, and the DXD-8 was simultaneously a PTP
Grandmaster, the same LOCK status would appear, but the REF line would indicate “REF: Input A/ Vid” (see example at 15.1).
11.1.2 MAIN ROTATION PAGES
The Main Rotation Pages are the pages appearing on the main display under normal operations when the DXD is neither in the
Status nor the Set Up mode. With the installation of the PTP and/or GPS options, some pages have been modified, others have
been added.
•REFERENCE SOURCES - PTP Mode
When PTP Mode is selected in the reference menu, the Reference
Sources page indicates the setting and the state of the PTP port in colors
for easy identification as well as the PTP domain to its right. For details
on the PTP states, see Chapter 11, PTP Ports States.
If GPS is available and has been selected in the reference menu as
‘LOCAL REF WHEN GM’, it will appear on the second section in place of
the ALT REF along with its lock status.
