Mounting MM 200
Use an appropriately sized C clamp or threaded rod strong enough for mounting MM 200.
The installation must always be secured with a backup safety attachment: namely an appropriate sized safety
cable. Don’t clamp the safety to the same threaded rod or the same C clamp. That defeats the reason for a
safety cable….namely a SEPARATE backup to the primary hanging mechanism.
Never stand directly below the device when mounting, removing or servicing the MM 200.
Please make sure MM 200 has been installed correctly both from a mechanical and electrical aspect before
powering up and operating for the first time. Spending a few extra minutes double-checking everything, is
better than rushing to turn the fixture on.
Care should be taken to mount MM 200. Make sure that MM 200 is mounted in such a way that no one can
touch it directly. For example, when hanging MM 200 make sure it is high enough up not to hit anyone’s head
or run into any obstruction in its movement. Always keep MM 200 away from any inflammable material.
Mounting MM 200 is a job that requires qualified personnel with experience. If the personnel doing the
installation lack these qualifications do not use them to do the installation.

DMX-512 control connection.
Connect the 3 pin XLR cable to the DMX controller and then to the first MM 200 in the daisy chain. Doing it this
way round avoids the pain of rewiring, if you get the wrong end of the cable back at the controller.
Continue wiring from one MM 200 to another in a daisy chain manner. Never try to Y split cables. Never try to
“star wire” a DMX cable run, it will not work.
If additional cable needs to be made up then two-core cable with a screen needs to be purchased. For wiring
please see the diagram below.
DMX has a maximum running distance of 330 feet. When long distances are involved then there is a tendency
for electrical noise to be evident. In that case, a DMX terminator will be required. The terminator helps prevent
corruption of the DMX signal. To make a DMX terminator simply solder a 120 ohm resistor across pins 2 and 3
of an XLR male connector. Then place that connector at the very end of the DMX cable run. In other words, at
the last MM 200.
