OPERATION
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 (
must be enabled.
DMX-512 control
T r 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.
V e 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, con-
troller 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 control
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 causes a voltage drop that can prevent lamps from striking and trip the main circuit breaker. To avoid this,
strike lamps at 5 second intervals.
L a m p o n ( l a m p s t r i k e )
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. This
option is set to off by default.
Lamp power can be switched on and off remotely from the controller. (For DMX commands see page 20.) Once the lamp is
on, additional lamp-on commands have no effect. If the lamp fails to strike in the MAC 600 E, repeated lamp-on com-
mands will fail until a lamp-off command is executed or fixture power is cycled off and on.
L a m p o f f
Power to the lamp can be turned off from a DMX controller by sending a value from 248 to 255 on channel 1 for 5 seconds if:
•
DMX Lamp Off (
•
DMX Lamp Off (
Be careful: it is not possible to strike the lamp for 8 minutes after executing a lamp-off command. The MAC 600/E however,
will store a lamp-on command and strike the lamp when the 8 minutes have elapsed.
MART

SPEC/dLOF
) is set to on, or
