DMX
The different pixel grouping, control mode and number of head modules fitted determine the number of
DMX channels used:
• Each pixel group requires four DMX channels (for Red/Green/Blue/CTC or Hue/Saturation/Value/CTC).
See “Pixel grouping” above.
• Control modes that incorporate effects use eight additional DMX channels. See “Control modes” above.
• When two head modules are installed, the DMX protocol is repeated in full for the second module, but
pan/tilt and fixture control channels are disabled.
The following table gives an overview of the number of channels used and the control menu settings applied
in the various modes.
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 fixture must be assigned its own control channels. Two MAC 401
Dual™ fixtures may share the same address, however, if identical behavior is desired. Address sharing can
be useful for diagnostic purposes and symmetrical control, 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.
Tailoring performance
The following performance options are available in the
PERS
menu.
Pan and tilt movement
The MAC 401 Dual™ provides several options for optimizing movement for different applications.
• Pan and tilt speed can be set to normal or fast with the
PTST
-
PTSP
command.
• The
PINV
and
TINV
commands invert the direction of pan and tilt and the
SWAP
command sets pan
commands to tilt and vice versa. These settings are useful for symmetrical effects with multiple fixtures.
