Minimizing 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 set up), you can avoid synchronization problems that cause 
unwanted image blanking or scrambling during input switches by doing the following:

NOTE:

  If the Sync to Matrix feature has been previously used, first see 

Removing 

the Sync to Matrix Script

 section on the previous page. 

1. 

While setting up the switcher and the DVS to work together, set the RGB delay on the 
matrix switcher, so it is equal to or greater than 1.0 second.

2. 

Create a tie on the matrix switcher from the desired input X to the output number that 
corresponds to input 4 on the DVS 304.

3. 

Immediately (within 1 second) recall the input preset on the DVS 304 associated with 
the input X on the matrix switcher.

NOTE:

  Input presets cannot be recalled via the front panel of the DVS 304. You 

can recall them via SIS commands (see 

SIS Communication and Control 

on 

the next page).
