When synchronising machines by RS422 and Video Syncs sub-frame offsets are not possible.
However when using the SR/MR to control the synchroniser within the machine or a synchroniser
then sub frame offsets may be possible.
To set a sub frame offset
1)
Enter the required sub frame offset (00..99)
2)
Key in Shift followed by Store followed by Chase/Offset
3)
If correct the display will show SubFrm 00:00:00:SS where SS is the sub frame offset entered.
To Recall a sub frame offset, use Shift followed by Recall followed by Chase/Offset.
Note.1 The Sub-frame Offset is cleared if you enter a zero offset, to enter an offset off 00:00:00:00:SS,
first clear the offset then enter the sub-frame offset required.
Note.2 Sub-Frame offsets are sent via the P2 protocol in two different ways either as a one-byte
number between 0..99 or 0..79 or a two-byte number. Root | IFace | Chase | Menu 53: Sub
Frame Offset selects the appropriate mode. When one byte offsets are required the user
should enter 0..99 or 0.79 as specified by the machine. Where two byte offsets are required
the user should enter the sub frame offset as a percentage (0..99).
Note.3 Sub Frame offsets have been tested on the following interfaces:-
1)
DA88/98 via the 15 pin remote
2)
Timeline Lynx
6.06 CLEAR ALL OFFSETS
To clear all offsets and disable chase on all machines:-
1) Select Master
2) [SHIFT] followed by [CHASE]
This function is available as macro key number 175.
6.07 OFFSET CHANGE LOCKOUT WHEN RECORD ENABLED/MASTER
To prevent accidental entry of offsets on record machines it is not possible to change the offset on
a record enabled machine. The warning message Master/Rec Enabled will be displayed in this
event. To enable/disable select:-
Setup | Root | Unit | Record | Menu 05:- Master/Rec Enb Offset Change
6.08 Shifter (Macro's on SR-4, SR-24 as standard)
The shifter is used to enter small temporary offsets to a machine in order to sync up one section.
The three shifter keys allow you to increment, decrement and reset the shifter value. The shifter
value is then added to the machine offset. With the shifter you do not have to remember the number
of frames or the direction of the temporary offset, this is held in the shifter memory and displayed
when the machine is selected.
6.09 Using the shifter to nudge offset's
As the shifter has dedicated increment and decrement keys it is ideal for nudging the offset of any
machine, the alternative requires three keys [1] [Trim+/-] [Offset]. The shifter display also keeps track
of what you have done. When you have finished adjusting the shifter use [Store] followed by {Shifter
Reset] to add the shifter contents to the current offset and reset the shifter.
6.10 The Colour Frame Key
When fitted the colour frame key changes the operation of the Store Offset command. The offset
must be in a multiple of 4 frames for correct colour framing. The defined offset will be modified so
as to be a multiple of 4 and within +/- 2 frames of the specified offset.
6.101 Colour Trim
To trim the colour frame offset enter the trim value (frames between 0 and 3), followed by [Store]
followed by [Colour Frame].
