PRECISION DMX USER GUIDE
The Precision DMX is the world’s smallest DMX controllable theatrical floodlight. This RGB fixture is
smaller than a fist yet packs comparable punch to traditional fixtures several times its size! No other
fixture on the market comes close to the compactness of this fixture with all the internal circuitry and
intelligence built in. The Precision DMX is a microprocessor based intelligent lighting fixture that can be
controlled to generate a wide range of vivid colors. Tunable preset functions allow the user to generate
various patterns without complex signaling. A built-in flicker generator can create unique and realistic
flame, surge, and lightning effects with ease. Standalone operation is achievable when the fixture is
configured with our free DMX Programmer iOS app, making the Precision DMX a fully color and effects
tunable floodlight that can operate without signal. The user simply sets the desired look of the Precision
DMX with the DMX Programmer iOS app and the output settings will be stored in the fixture’s memory.
Afterward, the Precision DMX may be unplugged from DMX signal and simply powered on; the fixture
will output according to the stored settings. This is an excellent feature for applications that need a fully
configurable light without DMX cabling.

DMX CHANNEL MAPPING
POWER AND WIRING REQUIREMENTS
The Precision DMX has a maximum fixture wattage of 3.8W 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, the
Precision DMX fixtures use 3.5mm TRS cables. Gantom makes 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 PRECISION DMX
Due to its compact size, the Precision DMX cannot use a physical DIP switch for addressing. Instead, the
Precision 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, brightness, and special
effect for the fixture if the application does not require any DMX control.
By default, the DMX starting address will be 1. The Precision DMX will flash several times when it is
powered on to indicate its starting address. If the Precision DMX 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.
Address reporting at startup can be toggled off in the settings menu covered later in this document.
What you need:
oAn 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.
oA male-to-male 3.5mm audio 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.
oPower 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.
oThe 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 the Precision DMX.
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
oAddress –This box shows the address that will be
assigned to the fixture if you hit the “Assign Address”
button
oAssign Address –This button will assign the selected
address to the fixture. The light fixture should blink in
response to having a new address assigned.
oSave 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.
oColor 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.
oStore 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.
oPre-Defined Macros –Selecting this button will bring
up a set of basic colors that can be selected without using
the color palette. A more detailed description of each
effect is in the following section.
oSpeed Slider –selects speed of the pre-defined macro

Precision DMX User Guide Version 1.0 –6/2/2017

following 6 colors: red, yellow, green, aqua, blue, and magenta
Candle Flicker: Causes the fixture to have a slight flicker as though it were a candle flame. Intensity of the
flickering can be adjusted using the “Speed”slider

OTHER OPTIONS SCREEN
If you hit the “Other Options” button on the control screen, the following menu appears:
oReset - selecting this will reset the fixture to its default
factory settings. Do this if you are running into programming
issues.
oToggle 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.
oLock/Unlock 9600 –The Precision 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.
