Chapter 4 • Connecting Multiple Switchers

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 PLUS.

B. Connect a cable from Intercom Out connector (RJ11) on the first System 8/10 PLUS and the other end into Intercom In connector (RJ11) of the second System 8/10 PLUS.

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 4xi. 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.
