Configuring a KMV-3901/3911 Cascade
This document explains how to connect up to three KMV-3901/3911 multiviewers in

Introduction
The number of sources that can be monitored concurrently on a single monitor wall display
is limited by the number of inputs supported by your specific multiviewer model. One
KMV-3901/3911 multiviewer supports 8 inputs. Depending on your purposes, you may
wish to monitor more sources on a single display. In the case of a Kaleido-X (7RU) or
Kaleido-X (4RU) multiviewer, you could add inputs by adding more input cards to the
frame. In the case of a Kaleido-X (7RU), once all input card slots are full, you could also use
the Expansion feature to increase the number of inputs even more. However, it is not
possible to add more inputs to a KMV-3901/3911 or Kaleido-X16 multiviewer.
Another way to increase the number of inputs is to use more than one multiviewer to build
the output to a single head, by configuring a multiviewer cascade. It is possible to configure
up to three Kaleido-X16 or KMV-3901/3911 multiviewers as a cascade system: the first
multiviewer provides some parts of the monitor wall image, sends it to the second one (if
any), which adds some more elements to the output, and then forwards it to the last
multiviewer, which sends the resulting output to the monitor wall display. Unlike the
cluster, whose purpose is to increase the number of output heads in a room, the cascade
increases the maximum number of inputs that can be displayed to a single head.
To configure up to three multiviewers as a cascade system, you need to physically connect
each multiviewer to the next, by using cascade bridges (Miranda part no.
KMV-3901-8XN-BRIDGE), and then connect a display to the appropriate output on the
leftmost KMV-3901/3911 card when facing the rear of the Densité frame. Remember that
this card is the one on the right when facing the front of the Densité frame. Once you have
defined your cascade system and room in XEdit, you will be able to operate the cascade as a
single multiviewer.
