10. Time Code Menus
Time Code is a separate option available for both DXD models, the DXD-8 and the DXD-16. It is described in a separate
manual (DXD/LTC). However, with the PTP option, menu 8.1 SMPTE 2059 SET UP becomes available.
10.1 SMPTE 2059 SETUP (MENU 8.1)
The Daily Jam is a process where the time code generator realigns precisely with the epoch
(midnight on Jan 1, 1970). This process occurs everyday, at the same time, as set in the DAILY
JAM TIME field.
•
Daily Jam Time:
The value entered in the DAILY JAM TIME field is the amount of time after
midnight, local time, at which the daily jam will occur.
Adjustments can be made in 10 minutes increments. Default value is 01 Hrs 00 Min, i.e. 1:00AM, local time.
•
Jam Time Recalculate
: Pressing the ENTER key while “Press Enter to Jam” is selected will cause the DXD to recalculate both
Jam Times, the time of the Previous Daily Jam Event and the time of the Next Daily Jam Event.
For time code, the Previous Daily Jam Event is the generator’s anchor point, until the Next Daily Jam Event. When the local
time is too close to the set Daily Jam Time, a manual change will not occur until the next day. By forcing the DXD to recalculate
both jam times manually, the operator has the option to make an immediate change.
10.2 LTC GENERATOR 1 & 2 (MENUs 8.2 & 8.3)
Menus 8.2 and 8.3 require the DXD/LTC. Otherwise, when trying to access these menus, a message will appear indicating
