16 MAC TW1 user manual
Setup
DANGER! Read “Safety Information” on page 3 before installing, powering, operating or
servicing the MAC TW1.
Important! Leave the MAC TW1 powered on for 20 minutes after dousing the lamp so that
cooling fans can reduce the temperature of the fixture. Failure to do so will result in
excessive heat buildup and may cause damage that is not covered by the product
warranty.
Control panel
You can set the MAC TW1’s DMX address,
configure individual fixture settings (personality),
read out data, and execute service utilities from
the fixture’s control panel. Settings can also be
changed remotely via the DMX link with the
Martin MP-2 uploader.
See “Control menu” starting on page 30 for a
complete list of the menus and commands
available in the control panel.
Menu navigation
The DMX address and any status messages (see page 34) are displayed on the control panel when the
MAC TW1 is powered on. To enter the menu, press [Menu]. Press [Up] and [Down] to move within the
menu. To select a function or submenu, press [Enter]. To escape a function or menu, press [Menu].
Note: [Enter] must be pressed and held for a few seconds to enter the Utilities menu (
).
DMX address and protocol
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 TW1s
may share the same address, however, if identical behavior is desired. Address sharing can be useful for
diagnostic purposes and symmetric control, particularly when combined with the inverse pan and tilt
options.
Depending on the selected DMX mode, the MAC TW1 requires 14 or 20 DMX channels. 16-bit basic mode
uses 14 channels and provides coarse control of all effects plus fine control of pan and tilt. 16-bit extended
mode uses 20 channels and provides the basic mode features plus fine control of electronic and mechanical
dimmers, cyan, magenta, yellow and zoom.
DMX addressing is limited to channels 1-499 in basic mode and 1-493 in extended mode. This makes it
impossible to set the DMX address so high that you are left without enough control channels for the fixture.
To set DMX address and basic or extended mode
1. Press [Menu] to enter the main menu.
2. Press [Up] or [Down] until
is displayed. Press [Enter]. To snap to channel 1, press [Enter] and
[Up]. Scroll to the desired channel and press [Enter]. Press [Menu] to return to the first level of the main
menu.
3. Press [Up] or [Down] until
is displayed. Press [Enter]. Select for basic mode, or for
extended mode. Press [Enter].
