DMX-512
The MAC 250 Krypton/Entour is compatible with USITT DMX512 controllers.
The full protocol is available in "DMX protocol" on page 33.
The fixture has two DMX operating modes, 16-bit and 16-bit Extended. 16-bit Extended mode uses 17 DMX
channels, three more than the 14 DMX channels than standard 16-bit mode requires. 16-bit Extended mode
provides more precise control of the dimmer color, and focus settings. All other functions are identical. See
"DMX protocol" on page 25.This section briefly describes the DMX-controllable effects. The DMX mode is
selected using the PSET option in the fixture control menu (see "Control menu" on page 41).
Lamp power
L A M P - O N
Unless automatic lamp strike is enabled, lamp power remains off until a lamp-on command is sent from the
controller.
Note: A peak of electric current that can be many times the operating current is drawn for an instant when
striking a discharge lamp. Striking many lamps at once may cause a voltage drop large enough to prevent
lamps from striking or draw enough current to trip circuit breakers. If sending lamp-on commands to multiple
fixtures, program a sequence that strikes lamps one at a time at 5 second intervals.
L A M P - O F F
The lamp can be turned off from the controller by sending the lamp-off command on channel 1 for 5
seconds. The lamp cannot be restruck for 8 minutes after being turned off. Note that the
lamp-off command may be disabled by the DMX Lamp-Off personality setting (
Effect position
R E S E T
If an effect loses its indexing and fails to move to programmed positions, the fixture can be reset from the
controller by sending the "Reset" command on channel 1 for 5 seconds. Note that the DMX reset feature
may be disabled by the DMX Reset personality setting (
D I M M E R / S H U T T E R
The mechanical dimmer/shutter system provides full, high-resolution dimming, "instant" open and blackout,
random and variable strobe effects, and random and variable pulses in which the dimmer snaps open and
slowly dims or snaps closed and slowly opens. Shutter, strobe, and pulse effects are selected on channel 1.
The intensity level is selected on channel 2. 16-bit Extended mode provides fine tuning of the intensity level
on channel 3.
C O L O R
The color wheel can be scrolled continuously - allowing for split color effects - or in steps, and rotated
randomly or continuously in both directions at different speeds. 16-bit Extended mode provides finer tuning
on channel 5 of the color setting selected on channel 4.

The MAC 250 Krypton/Entour has 7 indexed-rotation gobo positions plus an open position. Gobos can be
indexed (positioned at a defined angle), rotated continuously, or rotated and shaken (bounced). The gobo
and the type of movement are selected on channel 4 (channel 6 in 16-bit Extended mode) and the index
