Removing the Sync to Matrix Script
If the Sync to Matrix feature is no longer being used, the script can be removed
from the DVS by the following steps:
1 . Open the Signal Enhancements Windows Control program and connect to the
DVS via IP (not RS-232).
2 . Under the Tools menu, select Sync DVS 304 to Matrix Switcher... . The Sync
DVS 304 to Matrix Switcher window opens.
3 . Click Remove Script.
Minimize synchronization problems without using the Sync to Matrix
feature
This section describes how to manually implement the equivalent of the Sync to
Matrix feature without using a script loaded on the DVS 304, and instead relying
on a control system.
When operating the system using a manually configured control system (for which
Sync to matrix has not been setup), you can avoid synchronization problems that
cause unwanted image blanking or scrambling during input switches by doing the
following.
N If the Sync to Matrix feature has been previously used, first see Removing the
Sync to Matrix Script section above.
1 . While setting up the switcher and the DVS to work together, set rthe RGB
delay on the matrix switcher, equal to, or greater than 1.0 second.
2 . Create a tie on the matrix switcher from desired input X to the output number
that corresponds to the DVS 304’s Input 4.
3 . Immediately (within 1 second) recall the input preset on the DVS 304
associated with the input X on the matrix switcher.
N Input presets cannot be recalled via the DVS 304’s front panel. You can recall
them via SIS commands (see chapter 3, “Serial Communication”).
