334 Ion Operations Manual
Eos Configuration Utility Reference
You can force the desk to boot into the utility instead of the main desk application. During the boot
process, a countdown timer will appear. You will have 5 seconds to click the timer or to hold down
“e”, “o” and “s” at the same time on the connected alphanumeric keyboard.
Otherwise, you can always enter the ECU from the Ion application by choosing Browser>Exit.
If you want the desk to always boot into the utility, make sure {Open in Shell} is checked. See
“Open in Shell” on page337.

Starting Screen

This is the starting screen of the utility. From here you can choose to boot the desk in one of several
different modes, change various settings, or shutdown the desk.

Primary

This is the mode for using a single desk in non-networked or networked applications. On a system
with multiple desks, the primary is the desk that client and backup desks synchronize with, making
it the source of all information a client or backup desk sees on the network.
Primary mode can be run on Eos Ti, Eos, Gio, Ion and RPUs (Remote Processor Unit).

Backup

Backup mode requires a primary desk be online to synchronize. Once this is done, a backup desk
intakes all show data for use in the event that it needs to assume control of the lighting system.
The main difference between backup and client modes is what happens in the event of primary
processor failure. If the primary fails, a backup will ask if you want it to take control as the master of
the system or if you want to troubleshoot the problem. You can set the backup to automatically take
control. See “Backup Automatically Takes Control” on page343. When the primary remains in
control, the backup will behave as a client would.
Backup mode can be run on Eos Ti, Eos, Gio, Ion, and RPUs. For more information on Ion backup
systems, see Multi-console and Synchronized Backup, page 357.
