Fixture Programming
Programming control features for Studio Command
• Assigning a DMX start channel
• Accessing and setting fixture options
• Viewing fixture status
• Crossloading software
• Performing self tests
• DMX Programming for creating, storing, and playing scenes
The Onboard Menu System controls all these features via the LED display. A DMX console can
provide remote DMX programming to all fixtures on a link and, if it is running TalkBack protocol,
remote control of other fixture operations listed above.
For more information on the Studio Command Menu System, see Chapter 3: The Menu System
and Appendix D: Menu Map.
TalkBack
Support for Remote Access
All Studio Command fixtures support TalkBack" technology. TalkBack™ technology allows
remote access to the menu system built into High End Systems fixtures. A DMX console
supporting TalkBack can remotely access any option in the Studio Command onboard menu
system.
TalkBack protocol uses the normal DMX-512 connection for bi-directional communication with
the fixture so physical access to the fixture is no longer required to perform operations like
changing a DMX address or configuring preset programs. TalkBack protocol utilizes the primary
DMX link (pins 2-3) in a half-duplex communication mode. This means that it does not require
pins 4-5 to be connected or used to receive TalkBack messages coming from the fixture.
TalkBack protocol uses a discovery process to find the unique number that is embedded inside
each fixture, similar to a serial number. Once the fixtures have all been identified, the current
fixture parameter settings and information can be accessed. Fixture access can happen at
anytime, but the Talkback messages are only valid after the fixture starts homing.
