4. DMX-512 CONTROL CONNECTIONS
This fixture complies with international USITT DMX standards and can be used with either a 3 pin
or 5pin DMX connector. Plug in the provided 3pin XLR cable to the female 3pin XLR output of
your controller and the other side to the male 3pin XLR input of the MICROH FOG HORN
1200DMX. To connect the units to DMX, you must daisy chain the fixtures together as referred in
the diagram below. Always end your DMX-512 connection with a DMX terminator.
For installations where the DMX cable has to run a long distance, or is in an electrically noisy
environment, it is recommended to use a DMX terminator. This helps in preventing corruption of
the digital control signal by electrical noise. The DMX terminator is simply an XLR plug with a 120
Ω resistor connected between pins 2 and 3,which is then plugged into the output XLR socket of
the last fixture in the chain. Please see illustrations below.
5. SETUP
Be sure the unit is unplugged from the power source, remove the cap from the tank, and add the
‘MAXIMUM’ fog fluid up to fluid fill line. Be sure to not over fill the tank. Replace the cap and plug
unit in.
Turn the power switch on; you will notice the tank lights up RED. Once the unit is ready for use,
the illuminated tank will change to BLUE. Heat-up will take 3-5 minutes.
