Timing Channels

Three timing channels are provided: Focus Timing (Channel 9), Color Timing (Channel 10),

and Beam Timing (Channel 11). These channels can be used to communicate the desired

duration of a movement at the same time you communicate the destination of the

movement. The instructions below describe the general method of using a timing channel.

Specific instructions for recording cue fade times or part cues can be found in your control

console’s user manual.

Using timing channels to set parameter timing:

Step 1: Determine which timing channel controls the parameters you want to affect (see

Control, page 10).

Step 2: Set the timing channel to the appropriate value. Each step of DMX equals one

second of time. Percent-based consoles will have a granularity of ~2.5 seconds

per step. The maximum timing value is 4 minutes 15 seconds.

Step 3: Record the parameter channels and their corresponding timing channel into a

cue or cue part with zero fade timing. Avoid placing timing channel moves within

a cue or cue part that contains a fade time other than zero. Fading a timing

channel and its corresponding parameter channels can create unexpected

luminaire behavior.

Step 4: Repeat for other parameter channels and timing channels as needed.

Fan Speed Control Channel

The Fan Speed Control Channel (Channel 14) allows fan speed control for quieter fixture

operation. As long as this channel is at 0%, all fans will run at full speed for maximum

cooling. Setting this channel at incrementally higher values lowers the fan speed

incrementally.

For example, 25% = 75% fan speed, 50% = 50% fan speed, 75% = 25% fan speed, and so

on. Setting this channel at 100% will turn the fans off completely for silent operation.

Temperature sensors in the Revolution sense if fans are required to keep the fixture from

an over-temperature condition. These sensors override the fan speed channel and cause

the fans to operate to prevent over-heating, regardless of the channel setting.

For longer gel string life—especially saturated colors—keep the fan speed as high as

possible, that is, a lower value for channel 14.

Using Focus Timing for Console Response Option

Setting the Focus Timing Channel (Channel 9) at 100% provides more responsive manual

control of Revolution parameters. Remember to restore this channel to 0% (or the desired

timing speed value less than 100%) for smoothest cue playback operation.

Note:

Playback of cues with the Focus Channel set at 100% may result in less than satisfactory

luminaire movement.
