Meet TinyDMX

What is DMX?

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.

Who can benefit from TinyDMX?

• 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.

Operating your TinyDMX

Getting started is simple. Connect TinyDMX to your lighting system, power it via USB-C, and use the built-in button to cycle test modes. No console required.

1

Connecting to Your Lighting System

Use a modified CAT5 cable. Cut and strip one end, terminate the necessary wires, and connect to the DMX Out (RJ45) port on the TinyDMX.

Wire	Signal
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? Use a pre-made RJ45 to 5-pin DMX adapter to connect directly into your lighting system.

2

Powering Your TinyDMX

Use a USB-C cable connected to any standard USB power source — a laptop, wall plug, or phone charger.

Some battery packs may not provide stable output. For best results, use a dedicated power source rather than a rechargeable battery.

When TinyDMX powers on, it immediately sends a signal turning all connected lights to FULL — this is normal and confirms proper startup.

No power supply? Power TinyDMX from your phone using a USB-C to USB OTG adapter.

Controlling Lights

Press the Control Button to cycle through test modes. Each press changes the output, indicated by the LED on the unit.

Standard

• Full White Light All channels at 100%
• Half White Light All channels at 50%

3-Channel RGB Fixtures

• Red Red channel only
• Green Green channel only
• Blue Blue channel only

4-Channel RGBW Fixtures

• Red Red channel only
• Green Green channel only
• Blue Blue channel only
• White White channel only
• Off All channels off

TinyDMX does not auto-detect fixture type. In RGB/RGBW modes it outputs to every 3rd or 4th channel respectively. If your fixture uses a different layout, the output may not match the indicator light.
