System 4

xi

with Multiple System 8/10 P

LUS

Switchers

This configuration will work only with System 8/10 P

LUS

switchers in a daisy

chain configuration. (See the System 8/10 User’s Manual for details.) The master
of the System 8/10 P

LUS

chain must be configured in the “RS-232 only” projector

communications mode. The System 4

xi

will control the System 8/10 P

LUS

Switcher through the secondary RS-232 port by way of a System 4

xi

Slave

Adapter described on page 4-2. The System 4

xi

communicates with the first

System 8/10 P

LUS

, which in turn communicates with the second System 8/10

P

LUS

.

A. Use the Slave Adapter to connect the controlling device to the System 4

xi

and

to the first System 8/10 P

LUS

.

B. Connect a cable from Intercom Out connector (RJ11) on the first System 8/10
P

LUS

and the other end into Intercom In connector (RJ11) of the second System

8/10 P

LUS

.

C. Connect the RGBHV and
Audio outputs from the System 8/
10 P

LUS

master to the last input

of the System 4

xi

. Likewise,

connect the output of the second
slave to the last input of the first
slave.

Go to page 4-6 to set up the
System 8/10 P

LUS

switches.

Regardless of how the slave
switcher input connectors are
marked, they must conform to the
inputs of the System 4

xi

. They

are: R/C, G/Y/Video, B, H/HV &
V. Note that composite video
uses the G/Y connector.

After making all the cable
connections, go to page 4-7 to
configure the master/slave as a
system.

*

Extron recommends that audio

connections between switchers

be wired unbalanced. If

balanced connections are

required, insert a -6 dB pad in-

line to maintain 0 dB system

audio gain.
