System 4xi with Multiple System 8/10 PLUS Switchers
This configuration will work only with System 8/10 PLUS switchers in a daisy
chain configuration. (See the System 8/10 User’s Manual for details.) The master
of the System 8/10 PLUS chain must be configured in the “RS-232 only” projector
communications mode. The System 4xi will control the System 8/10 PLUS
Switcher through the secondary RS-232 port by way of a System 4xi Slave
Adapter described on page 4-2. The System 4xi communicates with the first
System 8/10 PLUS, which in turn communicates with the second System 8/10
PLUS.
A. Use the Slave Adapter to connect the controlling device to the System 4xi 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 PLUS.
C. Connect the RGBHV and
Audio outputs from the System 8/
10 PLUS master to the last input
of the System 4xi. 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 PLUS 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.
