Appendix A
DMX Control of Trackspot
®
Under DMX 512 protocol, each Trackspot fixture uses a block of seven
contiguous DMX channels for a total of 72 fixtures per link. Although
you can control Trackspot from any DMX starting channel you choose,
that starting channel must not interfere with another fixture’s channel
block.
The tables below assume that all Trackspot fixtures will be assigned to
the same link, one after another. Keep in mind, however, that if you
mix different devices on the same link, those devices will have different
channel blocks that may overlap the 7-channel sequence listed below.
Note: The values displayed in the tables in this appendix may
vary slightly depending on your controller’s rounding
convention.
Start Channels and Construct Parameters
If you chose DMX 512 protocol as your control mode, you must operate
your Trackspot fixture(s) either in low resolution or high resolution.
Control options available on your DMX controller will determine
whether you can operate your fixtures in low or high resolution mode.
Low Resolution Mode
Low resolution mode is used with DMX controllers that do not support
color or gobo fader and spin effects. There are fewer color and gobo
features available in low resolution mode.
High Resolution Mode
High resolution mode has more construct parameters and is intended
for DMX controllers with more accurate faders or direct numerical
control of each dim channel. In high resolution mode, the color fader
and gobo fader effects include half colors, oscillating colors, color spin
effects, and gobo spin effects.
After determining which DMX 512 mode you will operate in, see Table
A-1 for information such as DMX starting channels and address and
personality switch settings in both high and low resolution modes. For
construct parameters available in low resolution mode, see Table A-2.
For construct parameters available in high resolution mode, see Table
A-3.
