Setting the DMX Start Channel
Each trackspot Bolt fixture requires a block of 21 consecutive channels on a 512-Channel DMX
link for standard protocol.
Note: A reduced protocol using 20 channels is optional if your application
only requires 8-bit control of LED Dimming. You can use the menu
system to change the configuration to reduced protocol, (see
Selecting Protocol (PROT) on page 22).
To set the Start Channel on an
trackspot Bolt fixture:
1. Access the fixture’s menu
system via the LED display
on the fixture’s front
panel. For a detailed
description of the menu
system, see
Chapter 3:
The Menu System
on page
15.
2. To unlock the menu, press
and hold the <Menu
>
button until
AddR
appears
on the LED display. Press
the <Enter> button to select.
3. The display will show the start channel currently assigned to the fixture.
4. Use the <Up> and <Down> arrow buttons to select a valid DMX start channel from 0-491.
The display will flash a new option ready for selection. For more information on addressing
your fixture, see
Address Menu (AddR)
on page 18.
5. Press the <Enter> button to store the new DMX Start channel. The display will stop flashing
when a new option is entered.
When setting the Start channel on a fixture, remember:
• A fixture’s physical location on the link does not have to coincide with the order of channel
range assignments in the link.
• The fixture’s channel range must not overlap any other device’s channel range on the link.
When two devices on the same DMX link have overlapping channel ranges, one or both
devices will be disabled or behave erratically. The single exception would be if two or more
fixtures need to respond to controller commands in exactly the same way. In that case,
those fixtures must be the same type and must share the
entire
channel range.
