DMX-512 control
The MAC 600 (E) NT may be controlled with any DMX-512 controller. Four DMX modes are available that provide
different combinations of speed control and pan/tilt resolution.
T R A C K I N G M O D E
Tracking mode is available in all 4 DMX modes. In tracking mode the speed at which an effect moves is determined by
the controller’s fade time. The effect tracks the fade from one DMX value to another and a digital filter algorithm
ensures smooth movement at all fade speeds.
Two tracking algorithms are available to optimize movement for any controller. Algorithm 1 is recommended for use
with most controllers. Algorithm 2 provides smoother movement if the controller’s DMX value changes are uneven.
The number of DMX value changes used to calculate smooth movement is selectable between a level of 1 and 10. The
default level works well with most controllers. Increasing the level makes movement smoother but less responsive to
sudden DMX changes. Experiment for best results.
VECTOR MODE
Vector control is available in DMX modes 3 and 4. This mode provides direct speed control using 2 speed channels
and may result in smoother movement when using a controller with a slow or irregular refresh rate. Vector mode also
provides a “blackout” speed and overrides of the pan/tilt speed (PTSP), shortcut (SCUT), and studio mode (MOdE)
settings.
When vector control is used, the controller fade time should be set to 0, i.e., the position bumps from one value to the
next. However, tracking control may be enabled in vector mode by setting the speed channels to a tracking value.
8 - B I T M O D E
8-bit pan and tilt control is provided in DMX modes 1 and 3. This mode provides 256 pan positions in 1.7° steps and
256 tilt positions in 1.2° steps.
1 6 - B I T M O D E
16-bit pan and tilt control requires 2 additional channels and is available in DMX modes 2 and 4. This mode provides
32,768 pan positions in 0.013° steps and 45,567 tilt positions in 0.007° steps.
Lamp
The MAC 600 (E) NT can be set to automatically strike within 90 seconds of being powered on by setting Automatic
Lamp On (
S P E C / A L O N
) to ON. A delay determined by the fixture address prevents all lamps from striking at the
same time.
If Automatic Lamp On is set to off, the default, the lamp 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 the lamp. Striking many lamps at once may cause a voltage drop large enough to prevent lamps from striking
or trip the main circuit breaker. Avoid this by programming a “lamp on” sequence that strikes lamps one at a time at 5
second intervals.
