Connections with the ISS-6020
Connections with One ISS-6020 Switcher
Connecting your GT2000/GT2000R projector to a single ISS-6020 switcher (using a cable available separately) delivers a
series of benefits:
¥ You can handle input from ten sources simultaneously.
¥ The ISS-6020 can be controlled by the remote provided with your GT2000/GT2000R or with the buttons on the projector
cabinet. (Source selection without the use of a CTL-6010 cable must be performed with the GT2000 hand held remote...

E-29
Connections with Multiple ISS-6020 Switcher
You can accommodate as many as 100 sources by connecting your GT2000/GT2000R to one ISS-6020 switcher that acts as
master and ten more switchers that are slaves.
To connect several ISS-6020s, the Switcher Control on the Settings Menu should be set to SW 2 Level for multiple
projectors. (See page E-38.)
Note: The more ISS-6020 switchers that are connected, the more time is needed for the projector to start up.
