User Manual
For example, in Table 2-4, if you assigned fixture number 2 (F 02) to the
Technobeam set to reduced protocol, it would assume that all other
fixtures on the link are also using 14 DMX channels, so it will
erroneously try to receive channel 15 as the first channel in its channel
range. This would create channel overlapping because fixture number
1 (Technobeam iris protocol) is already using channel 15 in its 18-
channel range.
In this example, to prevent overlapping channels, you must assign
fixture number 3 (F 03) to the Technobeam (reduced protocol), even
though it is physically the second fixture on the DMX link. While this
would prevent overlapping channels, it would result in wasted
channels that could not be used (see Table 2-4).
Therefore, if you choose to assign fixture numbers to different types of
devices (and/or protocols) on the same DMX link, refer to “Fixture
Number to DMX Start Channel” on page A-16, which shows the channel
ranges reserved for each Technobeam fixture type. This table will help
you determine the next available DMX start channel/fixture number for
successive Technobeam fixtures on the link.
Upgrading Software
There are three ways you can upgrade the software (fixture-specific
operational code) to Technobeam fixtures attached to a DMX link:
• Uploading software from Status Cue. You will need to obtain
updated software from High End Systems or a dealer/distributor.
Consult the Status Cue User Manual for instructions on uploading.
