Setup
13
• The SERVICE LED lights if the fixture requires a service intervention. At the same time, a message
appears in the display indicating the type of service required.
The SERVICE LED blinks when the fixture is in factory service mode.
Restoring factory default settings
The MAC 401’s factory default settings can be restored by scrolling to the main
FACT
menu, pressing
[Enter], opening the
FACT
submenu and applying a
LOAD
command.
Three sets of custom user settings can also be stored and recalled from the main
FACT
menu.
Pixel grouping
In all DMX control modes, the LEDs in the MAC 401 Dual and CT Zoom can be controlled as one single
group or split into two or four segments that can be controlled as individual pixels.
The following options are available in the
DMX
-
PGRP
submenu:
•
1
– LEDs are divided into four segments A to D, giving Individual control of four pixel groups
•
2V
– LEDs are divided vertically into two segments A and B, giving individual control of two pixel groups
•
2H
– LEDs are divided horizontally into two segments A and B, giving individual control of two pixel
groups
•
All
– All LEDs are controlled together as one pixel (this is the default pixel grouping setting).
Pixel inversion
The
DMX
-
PINV
submenu can be used to invert the pixel settings, from left to right and top to bottom.
DMX setup
When one LED module is installed in the front of the head, the MAC 401 automatically sets
HEAD
to
SNGL
in the control panel, automatically recognizes the type of module installed and makes the correct
DMX protocol available. The module can be controlled using “DMX protocol, RGB Zoom module” on
page 25 or “DMX protocol, CT Zoom module” on page 31, depending on which type of module is installed.
If a second LED module is installed on the rear of the head, the MAC 401 automatically sets
HEAD
to
DUAL
in the control panel, automatically recognizes the types of module installed and makes the correct
DMX protocol available for each module, but it removes the pan, fine pan, tilt, fine tilt and fixture control
DMX channels from the protocol for the module installed on the rear of the head. These are only available in
the DMX protocol for the module installed on the front of the head.
DMX address setting
The DMX address, also known as the start channel, is the first channel used to receive instructions from the
controller. For independent control, each LED module must be assigned its own control channels. Two
modules of the same type in the same fixture or in different fixtures may share the same address, however,
if identical behavior is desired. Address sharing can be useful for diagnostic purposes and symmetrical
control of fixtures, particularly when combined with the inverse pan and tilt options.
The DMX address is configured using the
ADDR
menu in the control panel. The highest address available
is reduced depending on mode settings so that the fixture will always have enough DMX channels in the
512 available in a DMX universe. If the fixture is set up so that it uses 33 DMX channels, for example, the
highest address available will be 480.
