250 User Manual
*Note: Up to 28 Studio Spot 250 fixtures can be connected to one link.
Channels 505 - 512 cannot be used due to Studio Spot 250’s 18-
channel range.
**Note: Although there are enough available DMX channels to link up to 34
Studio Color 250 fixtures, you must use a DMX splitter to connect more
than 32 fixtures per link. The 32 device limit complies with the EIA-485
standard. Connecting more than 32 devices per link without a DMX
splitter will eventually deteriorate the digital signal.
Construct Parameters
Construct parameters (also referred to as DMX protocol) are the specific controller
values for each construct available on the fixture. For more information on the
available fixture constructs, see
“Fixture Constructs” on page 3-2.
