Determining Valid DMX Start Channels
The DMX start channel identifies each fixture on a link for the DMX controller. There
are 512 available channels on each DMX link. These 512 channels are divided among
all the devices on a particular link. The number of channels a fixture requires is
called the fixture’s channel range. The DMX start channel assigned to a particular
fixture is the first channel available to a fixture in its channel range.
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.
Remember the following criteria when determining a valid start channel:
•
The Start channel is the number of the first channel in a consecutive block of
channels assigned to an individual fixture.
• If you want two or more fixtures to respond to controller commands in exactly
the same way, you can assign them the same Start Channel. In that case, those
fixtures must be the same type and must share the
entire channel range.
• A fixture can be assigned the second block of DMX channels on a link without
physically being the second fixture on the link.
• To avoid overlapping channels, place the start channel at the beginning of a
range of available channels large enough to accommodate that fixture type.
• Every channel in the link does not need to be assigned.
• The channel range required for a fixture differs depending on the fixture type.
For more information on channel ranges the DMX protocol for ColorPower and all
High End Systems Dichroic Theatre fixtures and modules, see “DMX Programming”
on page 3-8.
The following sections describe using the menu system to set DMX Start channels for
ColorPower supply and attached color mixing units. For more information on the
ColorPower Menu system, see Chapter 3.
Setting the ColorPower Supply DMX Start Channel
The ColorPower supply requires one DMX channel. Choose a DMX start channel
that preceeds the start channel of any fixture the ColorPower supply controls. To set
the ColorPower Start channel:
1. Access ColorPower’s menu system via the LED display and four menu navigation
buttons to assign a Start channel to ColorPower, (see Figure 2-3). For more
information regarding the menu system, see “Menu Options” on page 3-2
