Manual
The module will be in manual switch mode. The Program
Output setting will be used to determine which signal is sent
to the output, regardless of signal validity.
Auto Switch Back
The module will be in auto switch back mode. Input A is the
primary input. If it becomes invalid, the output will switch to
Input B. If Input A returns to valid, then the output will switch
back to Input A.
Auto Switch
The module will be in auto switch mode. It will retain its
current route state until that signal becomes invalid, at which
point it will switch to the other input.
Table 6-3: Switch Mode Menu Options
6.4.1.3. Program Output
The Program Output combo box sets the output for the 7700ACO2-HD when the switch mode is set to
manual. The available options are Input 1 (the A input) or Input 2 (the B input).
6.4.1.4. Line Sync Control
The Line Sync Control combo box sets whether or not the line synchronizer is enabled out the output.
Table 6-4 describes the options and their function:
ON
Output video is fed through the line synchronizer. Output
timing will not be affected by video switches, but inputs must
be timed within ½ of a line of reference or they will be offset
on the output.
OFF
Output video is not fed through the line synchronizer. Output
timing will be affected by switches, and the switch will not be
clean unless the two signals are synchronous to the
reference, and the switch line is set correctly.

6.4.1.5. Vertical Phase
The Vertical Phase slider sets the vertical (by number of lines) phase offset of the output video with
respect to the path’s reference source. This control is only applicable if the line synchronization parameter
is enabled. The range of the control is dependent on the operating video standard.
