•TB I - Technobeam iris protocol - uses 18 DMX channels per fixture. This protocol should only be used with fixtures that have an iris.
•TLCD - Technopro LCD protocol - uses 18 DMX channels per fixture. This protocol should only be used with Technopro fixtures that are controlled with an LCD controller.
Selecting a Control Method
You must select a control method for each fixture: either a DMX start channel (recommended) or a fixture number (for a link with fixtures that all use the same number of DMX channels).
Note | Once you choose a control method, you should use that |
| same control method for all the fixtures on a link. |
DMX Start Channel Control Method
If you plan to combine different types of devices (and/or protocols) that use different numbers of channels on one DMX link, you should use the DMX start channel control method. Using the DMX start channel method to control your fixtures allows you to assign an explicit start channel to each fixture, so no DMX channels are wasted. For more information, see “Wasted DMX Channels” on page
To select the DMX start channel control method:
1. Press and hold the <Menu> button until “ADDR” appears on the LED display.
2. Using the <Up> and <Down> arrow buttons, scroll to the “SET” menu and press the <Enter> button to select the “SET” menu.
3. Using the <Up> and <Down> arrow buttons, scroll to the “CHNL” menu and press the <Enter> button to select the “CHNL” menu.
4. Using the <Up> and <Down> arrow buttons, scroll to the “DMX” option and press the <Enter> button to select the “DMX” option.
Note | You must select a control method for each Technobeam |
| fixture on the link. |
Fixture Number Control Method
When you use the fixture number control method, each fixture “thinks” all other devices on the link use the same number of DMX channels that it uses. Therefore, using the fixture number control method is a good idea only if you plan to link fixtures that all use the same number of DMX channels.
For example, assign fixture numbers if you have a link that only controls Technobeams set to iris protocol (or other devices that use 18 DMX channels), or a link that only controls Technobeams set to reduced protocol (or other devices that use 14 channels per link).
