Chapter 4 • Connecting Multiple Switchers
Looping the System 4
xi
with Other Switchers
The System 4
xi
can be interconnected, or “looped” with other switchers to allow
for a greater number of inputs to be switched to the projector. With each of these
configurations, the System 4
xi acts as the “Master”, to communicate with the
projector and supply the video signal. The switcher that provides input to the
System 4
xi
is the “Slave”. If two switchers are looped with the System 4
xi
, the
second switcher is a “Slave” to the first, and the first is a “Slave” to the
System 4
xi
.
• The slave switcher is always connected to the highest master input (input #4
on a System 4 xi , input #10 on a System 10 and input #8 on a System 8, etc.).
• Input numbering always starts at input #1 of the System 4
xi
and input #4 will
become the first input from the “slave” switcher.
• The System 4 xi cannot be used as a slave switcher.
• The only switchers that can be looped with the System 4 xi are:
Extron’s SW4 ARMX, SW6 ARMX, System 8 P LUS and System 10 P LUS .
• In any master/slave arrangement, the System 4 xi acts as if it is one large
switcher. That is, each slave input can be selected and set up from the
System 4
xi Front Panel. Any Slave input can be configured for any signal
type.
For example, a System 4LD
xi
with a System 8 P LUS as a slave is seen by PC
software as a line-doubling, 11-input switcher.
Input Channel Addressing
The System 4 xi must be set up to recognize input that is from another switcher
unit. The Front Panel operation in Chapter 3 explains how this is done. In a
master/slave configuration, input channel numbers of 4 or higher are translated
and sent to the appropriate slave input number. For example, selecting input #9
will select input #4 on the System 4
xi , and then tell the slave switcher to select its
input #6. See shaded table entry below.

* Channel numbers continue if multiple switchers are used as slaves. The
highest number of channels is 22, using two System 10 P
LUS units as slaves.
The following pages show configurations for looping the System 4 xi with other
Extron-approved switchers. Looping the System 4
xi
will not work with all
switchers; call Extron Electronics if you have any questions.
