GANTOM DMX USER GUIDE
The Gantom DMX is a 4W controllable LED light for professional applications. Featuring a non-linear
dimming curve, the Gantom DMX can be dimmed with high precision even at the lowest intensity levels.
Homogeneous optics smoothly blend the colors of the internal quad chip LED producing a clean
projected field without the “halos” seen in many other color mixing fixtures. High frequency hybrid
modulation allows the Gantom DMX to be used in video applications with minimal on-camera flickering.
The Gantom DMX can even be battery powered for portable applications, perfect for event lighting
where access to power and signal is inconvenient. The Gantom DMX is configured using our DMX
Programmer app, available free for Apple and Android devices.
Features
o Homogeneous wide beam angles
o Non-linear dimming curve for smooth fading without visible “steps” in output intensity
o 14 bit dimming compressed into single 8 bit channel gives precision control without using extra
channels
o DMX address and colors configured via DMX Programmer app
o Less than 5W at full output
o Minimized on-camera flicker
o Integrated DMX receiver
o Integrated quad channel constant current driver for consistent output
o IP65 rated for indoor and outdoor use with occasional liquid exposure
Available Models
The Gantom DMX is available in full color RGBW or Dynamic White. It is also available as either a Spot or

POWER AND WIRING REQUIREMENTS
The Gantom DMX has a maximum fixture wattage of 4.8W and an operating voltage of 12V DC. For
recommended power supplies check http://www.gantom.com/power-supplies/
Rather than using a typical XLR cable for carrying the DMX signal, Gantom DMX
fixtures use 3.5mm TRS cables. Gantom makes the an XLR 5 Pin to 3.5mm TRS
adapter (product number CB51) that is perfect for connecting into an XLR based
DMX environment.
Additionally, screw terminal adapters are
included with every fixture to simplify
custom wiring. You can screw bare wires
directly into these adapters.

ADDRESSING YOUR GANTOM DMX
Due to its compact size, the Gantom DMX cannot use a physical DIP switch for addressing. Instead, the
Gantom DMX is programmed using the DMX Programmer App by Gantom. In addition to setting the
DMX starting address for the fixture, the app allows you to save a default color and brightness for the
fixture if the application does not require any DMX control.
By default, the DMX starting address will be 1. The Gantom DMX will flash several times when it is
powered on to indicate its starting address. If the Gantom DMX RGBW is assigned to address 245 it will
report its address by flashing red 2 times, then flashing green 4 times, then flashing blue 5 times. If it is
assigned to DMX address 038, it will flash red 0 times, then flash green 3 times, then flash blue 8 times.
For a Gantom DMX DW fixture, the fixture will flash the cool white LEDs for the first digit, the warm
white LEDs for the second digit, and then the cool white LEDs again for the third digit. If the starting
address is 358, the fixture will flash the cool white LEDs 3 times, then flash the warm white LEDs 5 times,
then flash the cool white LEDs 8 times. Address reporting at startup can be toggled off in the settings
menu covered later in this document.
What you need:
o An Android or iOS device for running the Gantom Programmer app. Please note that a
headphone port is required to connect to the device to the fixture. The iPhone7 does work
with, but you will need to use the headphone port adapter that is included with the phone.
o A male-to-male 3.5mm audio 3.5mm cable. This is the same type of cable that you would use to
connect your Android or iOS device to headphones or to an AUX port.
o Power supply for the fixture. All Gantom fixtures accept 12v DC power. We recommend using
one of our PowerPak Mini units if you are just going to power a single fixture.
o The free DMX Programmer app by Gantom. This can be found by searching “Gantom” in iTunes
for an Apple device or Google Play for an Android device
First, open the DMX Programmer app by Gantom. The app will open to
the screen you see here. From this screen, select either the Gantom DMX
RGBW or the Gantom DMX DW.
The app will then provide you instructions on how to connect the light
fixture to the tablet or smartphone. Please note the order in which the
cables should be connected. First connect the headphone cable to the
light fixture and to the tablet/smartphone. Next, connect the power to
the fixture. When prompted by the app, tap the “Next” button and you
will be taken to the control screen.

CONTROL SCREEN
o Address – This box shows the address that will be
assigned to the fixture if you hit the “Assign Address”
button
o Assign Address – Hitting this button will assign the
selected address to the fixture. The light fixture should
blink in response to having a new address assigned.
o Save button – this will allow you to save a settings
profile into the app. Use this if you need to configure
many fixtures to have the exact same settings. Please
note that this button DOES NOT save the current profile
or address to the fixture.
o Color Palette – the color palette will allow you to set
the light to any RGB color. This is useful if you do not
need live DMX control and would like to set the fixture to
a default color at startup. Please note that for the
Gantom DMX DW the color palette is replaced with a
color temperature slider.
o Store as Default – hitting this will save the current
color and brightness to be the default state for the light
when it turns on. If the light does not see DMX signal
when it is powered on, it will go to this state.
o Pre-Defined Macros – Selecting this button will bring
up a set of basic colors that can be selected without
using the color palette.

OTHER OPTIONS SCREEN
If you hit the “Other Options” button on the control screen, the following menu appears:
o Reset - selecting this will reset the fixture to its default
factory settings. Do this if you are running into programming
issues.
o Toggle Silent Bootup – By default, the fixture will flash to
report its DMX address when it is powered on. Hitting the
“Toggle Silent Bootup” setting will turn address reporting at
startup on or off.
o Lock/Unlock 9600 – The Gantom DMX fixture can listen
to either a standard DMX signal OR to the special control
signal that comes from the app. Lock 9600 will turn OFF the
fixture’s ability to listen to DMX and ONLY allow it to be
controlled through the app interface. For most applications it
is recommended that you keep “UNLOCK 9600” selected.
