Configuring the DMX512 ports
Once your console is installed, you may need to reset some hardware
configuration settings. The Output Configuration screen allows you to
reset the starting dimmer numbers for your DMX512 ports, set your ports
for dimmer doubling and adjust the DMX512 signal speed if your dimming
system requires a slower signal.
Port starting dimmer numbers
Each port has a starting dimmer number which can re reset in the Output
Configuration display. Shown above are the default starting dimmer
numbers for consoles with three DMX512 ports.
Unless using dimmer doubling, 2 you might want to set different starting
numbers, such as when default port settings would result in some racks
being connected to two ports. For example, if your system included 15
racks, each with 96 dimmers, you could set ports 2 and 3 to start at 481
and 961.
Set port starting numbers in the Output Configuration screen as follows:
1. Press [Setup] to display the Setup Menu.
2. Press [2], Output Configuration, and press [Enter].
3. Press [↓] to select the port to configure (port 1, 2 or 3).
4. Press [S3], Starting Dimmer.
5. Enter the desired starting number for the port.
6. Press [Enter] twice to confirm your choice.

You cannot change starting dimmer numbers when using Dimmer
Doubling. See Setting the port to Dimmer Doubling, page 334.
