What does this module do?

This module is designed to route and set the Video Wall Scaler Modes for compatible DM devices. The layout of the video wall is 4 wide by 2 tall, and using (X,Y) coordinates, X1-Y1 would be the top left, and X2-Y2 would be the bottom right. I only account for a 16:9 aspect ratio, so when a set of displays are set to a single display, it will be 2x2. See MODES for layout examples.

To be clear, this module DOES NOT route a video source to the full 4x2. It will only route in 2x2 quadrants.

The outputs of your video wall needs to be as depicted:

When you set a Video Wall Mode, the routes are saved in a structure. When changing Video Wall Modes, these routes will be recalled if the mode has been used before. This is to prevent routing artifacts from occurring.

For example:

1. default Mode 1:

• user routes input 2 to A
• user routes input 3 to B

2. user sets Mode 2:

• user routes input 4 to 1
• user routes input 5 to 2
• user routes input 6 to 3
• user routes input 7 to 4
• user routes input 8 to B

3. user sets Mode 1:

• Module will route input 2 to A
• Module will route input 3 to B

4. user sets Mode 2:

• Module will route input 4 to 1
• Module will route input 5 to 2
• Module will route input 6 to 3
• Module will route input 7 to 4
• Module will route input 8 to B
