TalkBack™ Protocol

TalkBack™ technology is a new feature that allows remote access to the menu system built into High End Systems fixtures. Any menu item

available is accessible remotely with Talkback protocol.

TalkBack protocol uses the normal DMX-512 connection for bi-directional communication with the fixture so you don't need physical access

to perform operations like changing a DMX address or configuring preset programs. You can configure any fixture supporting TalkBack

protocol on a DMX-512 link if you have access to the cable.

TalkBack protocol uses a discovery process to find the unique number that is embedded inside each fixture, similar to a serial number. The

HandShake controller utilizes this discovery process to find all the fixture on the link supporting TalkBack protocol.

Once the fixtures have all been identified, the current fixture parameter settings and information can be discovered. Fixture discovery can

happen at anytime, but the Talkback messages are only valid after the fixture starts homing.

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.
