This section describes the MAC 600/E’s controllable features and the options for customizing them for your application. Option
selection is described in the next section.
Martin RS-485 control
The MAC 600/E may be controlled with the Martin 3032 controller. For the fixture to respond, either the protocol setting
(
PSET
) must be set to Martin (
MART
) as described in the previous section, or automatic protocol detection (
SPEC/AUTO
)
must be enabled.
DMX-512 control
Tr a c k i n g m o d e
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.
There are 2 selectable tracking algorithms to provide extremely smooth movement with any controller. Algorithm 1 calculates
speed based on the absolute value of DMX changes; it is recommended for use with most controllers. Algorithm 2 uses the
real value of DMX changes to calculate speed and may provide smoother movement if the controller-calculated DMX values
are uneven.
The number of samples, that is, changes in DMX values, used by both algorithms to calculate speed is selectable between a
level of 1 to 10. The ideal setting will vary from controller to controller - experiment for best results. Increasing the number of
samples makes movement less responsive to sudden DMX changes and smoother as a result.
Ve c t o r m o d e
In vector mode, 2 speed channels provide a way to control the effects’ speed with controllers that do not have programmable
fade times. This mode 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)
menu settings.
In vector mode the controller fade time should be set to 0, i.e., the position bumps from one value to the next. However,
controller fade times can be enabled by setting the speed channel between 0 and 2.
8 - b i t v e r s u s 1 6 - b i t p a n / t i l t r e s o l u t i o n
With 8-bit pan/tilt resolution, the pan and tilt are divided into 256 equal increments. Finer position control and smoother
movement is provided in the 16-bit modes.
Lamp
The MAC 600/E can be set to automatically strike within 90 seconds of being powered on by setting Automatic Lamp On
(
SPEC/ALON
) 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.
Power to the lamp can be turned off from the controller if the DMX Lamp Off (
SPEC/dLOF
) feature is enabled. There is a
combination of DMX values that allows you to turn off the lamp even if this feature is disabled. %HFDUHIXO: it is not
possible to strike the lamp within 8 minutes of having switched it off. The MAC 600/E will store a “lamp on” command and
strike the lamp automatically when the 8 minutes have elapsed.
With the MAC 600 E, lamp power falls to 400 watts for cooler operation and longer lamp life when the shutter is closed for 10
seconds. Power instantly returns to full when the shutter opens. Reduced-power mode with the shutter open can be forced by
setting channel 1 to a DMX value from 116 to 122.
