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.
