Chapter 3: Fixture Operation; Talkback™ Support For Remote Access - High End Systems DL.1 User Manual

Chapter 3:
Fixture Operation
The DL.1 fixture operates on a DMX link to project output from any video source
including from the Catalyst Media Server. This chapter outlines the DL.1 fixture's
onboard menu system. For more information on operating the fixture with a
controller, consult the controller documentation.
The DL.1 fixture's on-board menu system allows the user to:
• Set a start channel
• Enable and disable default parameter settings
• Crossload firmware
• Home the fixture
• Test movement and sensor functions
• View software version, temperature, lamp information, fixture information, DMX
values, and errors.
TalkBack™ Support for Remote Access
All DL.1 fixtures support TalkBack" technology. TalkBack™ technology allows
remote access to the menu system built into High End Systems fixtures. A DMX
controller supporting TalkBack can remotely access any option in the DL.1 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 embed-
ded 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.
