About Global Configurator (GC)
What It Does
Global Configurator is the software tool for setting up an MLC and the system it controls.
Global Configurator:
z Loads device drivers and uses commands from them for controlling other products
z Creates a single configuration file containing all the settings for the MLC and the products it interacts with in the AV
system
z Generates a graphical user interface called GlobalViewer that is uploaded to the MLC (a GlobalViewer host device)
along with the completed configuration and can be accessed as a web page

NOTES:
• Use the front panel
Config port and
rear panel Host
Control ports only
for sending basic
SIS commands (such
as those for IP
setup and
troubleshooting)
and checking unit
information and
responses.
• You must use the
LAN port (not the
Config or Host
port) to set up the
MLC and upload
GC configuration
files or firmware.
