Configuring a KMV-3901/3911 Cascade
This document explains how to connect up to three KMV-3901/3911 multiviewers in
cascade mode, and how to configure and operate them as a single system.
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.
The 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 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.
Physical Installation
Installing Cascade Bridges
Before you interconnect two KMV-3901/3911 cards by using the cascade bridge (Miranda
part no. KMV-3901-8XN-BRIDGE), make sure the cards are placed in locations adjacent to
one another inside the Densité frame, and firmly seated into their respective slot. It is not
necessary to switch off the frame’s power when installing or removing a cascade bridge.
IMPORTANT
Precautions should be taken to avoid electrostatic discharges
The cascade bridge connects directly to static-sensitive components on the
KMV-3901/3911. Miranda recommends using static-control measures, such
as a properly-grounded wrist strap, or conductive footwear and flooring,
while you handle cascade bridges.
