Take (switch preview output to program output)
NOTE: The cut or dissolve effect is determined by the Switching Effect,
X2(
(0 = cut, 1 = dissolve) *4# command. See “Command
and Response Table for Special Function SIS Commands” on page 49.
The preview switch mode, stay or swap, determines the preview output after the take command.
• In stay mode, the preview output remains unchanged (both outputs share the same input).
• In swap mode, the program output switches to the preview output (the two outputs swap inputs).

) indicates that the switcher has received and is responding to the “Take” command.
A larger series of switcher-initiated messages follows the Tke response during a cut or dissolve operation. The following two examples
show the sequence of responses to a “Take” command in stay and swap mode. See Busy (cut and dissolve) earlier in this chapter for
more details about the responses after the Tke response.
Example (stay mode):
