Terminate/
Termination Termination refers to the dampening of DMX signal at the end of the transmission line. Termination is
created by placing a 100 ohm resistor between pins 2 and 3 of the DMX line. Often, there is a switch on
DMX devices to do this internally. If not, a terminator is provided in the form of an XLR connector with the
proper resistor between pins 2 and 3 to be placed in the DMX Thru port on the device.
Tilt The movement of the luminaire around the axis of the tilt tube.
Time Control of the duration of the change of the variable parameters of some automated luminaires and other
devices in a lighting system.
Timing
Channel A Timing Channel is used in lieu of cue fade rate to determine the time it will take a luminaire to move from
one setting to another. For example, a cue in which a luminaire pans from one side of stage to the other may
look "steppy" if cue fade rate is used, because of the nature of the DMX512 signal. To overcome this, a
timing channel allows the luminaire to calculate the move "in time," effectively smoothing out the
movement.
Zero
Position Pan and Tilt values at 50%. Also called "Home Position" or a "50/50" cue or group.
Zoom Table Allows the fixture to maintain sharp focus on an image throughout the zoom range. (Note that zoom tables
are sensitive to throw distance. For this reason, a variety of zoom table versions are available for use with
different throws.)
8-Bit DMX The universally accepted lighting control protocol in the entertainment industry. A console uses this protocol
to control specific devices in a lighting system. A DMX512 channel packet is eight bits of absolute parameter
data. 8-bit refers to the resolution of the signal: 256 step resolution, providing channel values from 0 through
255. A DMX512 data packet is a group of 512 data channels.
16-Bit DMX To smooth out the movement of automated luminaires, the industry has adopted 16-bit DMX. This is not a
change to the DMX512 specification, rather a change in the way luminaires and consoles treat DMX512
information. In practice, 16-bit DMX adds a DMX512 channel each to pan and tilt - pan coarse, pan fine, tilt
coarse, tilt fine, instead of just pan and tilt. The console and luminaire combine these levels and increase the
resolution of pan and tilt from 256 steps to a theoretical maximum 65,536 steps at the console level, resulting
in the ability to position the luminaire more accurately.
