SEQ
SEQUENCE MODE (CONT’D)
In single destination mode the user is prompted to select a source:
3 Destination = Studio A, Select Source
VTR_01 VTR_02 VTR_03 ENGNRING STUDIO_A STUDIO_D MONITR45 MONITR46
Figure 6−90.
The user may then set up any kind of basic or complex source selection per normal operation. Destination changes/selections
are also recorded as part of the Sequence definition. Audio mode selections are relevant to the specific switch being defined.
All irrelevant keys are ignored during definition; i.e. MENU, PROT/LOCK, OVERRIDE. When the operator has completed
all desired switches, the blinking SEQ button is selected to complete the definition; the menu will return to Define Sequence
Mode as shown (SEQ button stops blinking, remains red):
3 Defining Sequence − Completed − Select TAKE To Confirm Or CLEAR To Cancel
TST_SQ17 TST_SQ18 USRSEQ20 USRSEQ21
Figure 6−91. Example Sequence Definition Menu − Page 3, Fifth Button Position Defined.
From this menu the definition can be confirmed by pressing TAKE, or CLEAR can be selected to return to the Home Defining
Sequence menu to try again. Pressing TAKE will also return the panel to Sequence Selection mode, an additional press of
the SEQ button is required for each completed definition.
Note that the switches are not performed during sequence definition. To execute the defined sequence, the operator must select
it from the menu.
Important: Since user defined sequences have a large memory requirement, they should be defined from the file
server whenever possible. This applies especially to sequences with eight−character names.
Sequence Definitions may also be aborted at any time by selecting the SEQ button when it is blinking red. A brief message
will appear on the top line stating “SEQUENCE DEFINITION ABORTED” and the panel will return to the Sequence selec-
tion menu and the SEQ button will illuminate in green.
If the user enters too many switches and fills the sequence, the following prompt will appear:
1 Sequence <USRSEQ21> Full. Press TAKE to Finish or CLEAR to Cancel
TST_SQ17 TST_SQ18 USRSEQ20 −DEFINE−
Figure 6−92. Example Sequence Definition Menu − Too many entries.
Pressing the TAKE button completes the sequence at the current switch. Pressing CLEAR cancels the sequence entry.
