Meet TinyDMX, your pocket-sized DMX console.
Whether you’re testing data lines, checking terminations, or verifying mid-stream signal flow, TinyDMX sends out DMX512 control so you can troubleshoot quickly and confidently.
No more risking your expensive console or unplugging half the rig to figure out what’s going on.
Just plug it in. Test. Done.
DMX, short for Digital Multiplex, is a standardized protocol used to control lighting and effects equipment from a central source. It enables precise communication between controllers and devices such as lighting fixtures, fog machines, moving heads, and dimmers, all over a single data line.
Widely used in stage lighting, architectural installations, and live events, DMX is the backbone of modern lighting control, offering flexibility, reliability, and real-time responsiveness across complex setups.
Field technicians who need a fast, reliable way to verify DMX signal integrity on-site, without hauling out a full console.
Electricians and general trades who may not be familiar with DMX but need to validate wiring or troubleshoot data lines.
AV and lighting installers who want a quick go/no-go test tool during system commissioning.
Anyone needing a lightweight, portable DMX tester to avoid delays, miswiring, or unnecessary back-and-forth on job sites.
TinyDMX makes it easy to verify that your DMX chain is working—saving time, preventing headaches, and reducing costly mistakes.
Getting started is simple. This guide will walk you through how to:
Connect TinyDMX to your lighting system
Power it up via USB-C
Trigger fixtures using its built-in DMX output
Whether you’re testing a rig or troubleshooting a data line, TinyDMX gets the job done fast — no console required.
CAT5 Termination
To connect TinyDMX, you’ll use a modified CAT5 cable. Cut and strip one end, then terminate the necessary wires and connect them to your lighting system using the DMX Out (RJ45) port on the TinyDMX.
Wire Mapping:
Orange/White → Data +
Orange → Data –
Brown or Brown/White → Ground
⚠️ Make sure the tab on the RJ45 connector is facing away from you when following the pinout.
Prefer a faster setup? You can also use a pre-made RJ45 to 5-pin DMX adapter to connect TinyDMX directly into your lighting system.
Once your TinyDMX is connected to your lighting system, it’s time to power it up.
Use a USB-C cable to connect the device to a standard USB power source, such as a laptop, USB wall plug, or phone charger.
⚠️ Note: TinyDMX uses very little power, but some battery packs or power banks may not provide stable output. For best results, use a dedicated power source (not a rechargeable battery).
When TinyDMX powers on, it will immediately send a signal to turn all connected lights to FULL—this is normal and indicates proper startup.
No power supply? You can power TinyDMX directly from your phone using a standard USB-C to USB adapter (OTG-compatible)
Once TinyDMX is powered on and connected, press the Control Button on the device to cycle through the available test modes.
Each press will change the output, indicated by the LED Indicator on the unit. These modes help confirm channel functionality across different fixture types.
Available Modes:
Full White Light – All channels at 100%
Half White Light – All channels at 50%
For 3-Channel RGB Fixtures:
Red – Red channel only
Green – Green channel only
Blue – Blue channel only
For 4-Channel RGBW Fixtures:
Red – Red channel only
Green – Green channel only
Blue – Blue channel only
White – White channel only
Off – All channels off
Please note, TinyDMX does not detect whether it is connected to a 3- or 4-channel fixture. In those test modes, it simply outputs to every 3rd or 4th channel. If your fixture uses a different channel layout, the output may not match the indicator light.
Important Disclaimer
We do not recommend using TinyDMX to test moving-light fixtures. Movement and pan/tilt functions can behave unpredictably
when driven by the TinyDMX test modes, and is intended primarily for basic fixtures and simple channel testing.
🎉 Congrats! You’ve successfully set up and used your TinyDMX.
Whether you’re testing fixtures, troubleshooting a data line, or just making sure the job site is ready,
TinyDMX helps you do it fast — with no console, no hassle.
