Application 2: Connecting Multiple MGP 464s in
Succession (Daisy-chaining)
By connecting multiple MGP 464s together in succession ("daisy-chaining") via the
DVI Output and DVI Background connectors, you can display up to 12 windows
on the output screen. You can connect up to three MGPs in this way. (See the
diagrams on the next page.)
Connecting via the DVI Background connector has the advantage of the input not
being scaled. Therefore, no analog/digital sampling is required and there is no
signal loss.
N In the diagrams, the MGPs are given letters in the order of their priority,
The illustration on the next page shows diagrams of three possible configurations.

6-6 MGP 464 • Special Applications
starting with the unit closest to the output display. Therefore, the first MGP
in the chain is shown as unit C (or B, if there are only two MGPs). The second
MGP is designated as unit B, and the third is unit A.
8-window configuration: Two MGP 464s are daisy-chained together, so that
eight windows (four from each MGP) are displayed on the output screen.
• The DVI Output of the first MGP (unit B) is connected to the DVI
Background input of the second MGP (unit A).
• The first diagram in the row shows the output display with one MGP
attached. The second diagram shows the display with two MGPs
attached.
12-window configuration: Three MGP 464s are daisy-chained so that 12
windows are displayed on the output screen.
• The DVI Output of the first MGP (unit C) is connected to the DVI
Background input of the second MGP (unit B).
• The DVI Output of the second MGP (unit B) is connected to the DVI
Background input of the third MGP (unit A).
• The first diagram in the row shows the output display with one MGP
attached. The second diagram shows the display with two MGPs
attached. The third diagram shows the display with all three units
connected.
8-window with DVI background configuration: A DVI computer (or another
DVI source) is daisy-chained to two MGP 464s, so that eight windows are
displayed in front of a live video background from the DVI source.
• The DVI source is connected to the DVI Background input of the first
MGP (unit A).
• The DVI Output of the first MGP (unit B) is connected to the DVI
Background input of the second MGP (unit B).
• The first diagram in the row shows the DVI computer, which is the input
source. The second diagram shows the display with one MGP attached.
The third diagram shows the display connected to two MGPs.
