DMXcat® makes it easy for anyone to control, analyze, or test any DMX lighting fixture, whether it’s a simple LED PAR or a complex moving light. The system consists of a small hardware dongle (purchased separately) and a suite of free mobile applications. Together, they combine to bring wireless DMX and RDM control plus other useful lighting functions to the user’s smartphone. The DMXcat solves the problem faced by all users of modern lighting equipment: How to turn on and test DMX lighting gear without using a complicated lighting console.

DMXcat app is now available in seven languages: Spanish, French, German, Italian, Korean, Japanese, and English.

Software Applications
There are currently five apps available for use with the DMXcat system:
•DMX Controller: A single universe (512) DMX channel controller with two user interfaces (sliders or keypad).
•Fixture Controller: Controls multi-attribute fixtures from a built in database.
•RDM Controller: For bi-directional communication and control of RDM enabled devices.
•DMX Tester: Analyze and adjust settings for transmitting or receiving DMX.
•DIP switch calculator: Simplifies the configuring of DIP switches used for setting DMX addresses.

The DMXcat’s hardware interface is a compact battery powered device which fits easily in a pocket or tool pouch or may be worn on a belt. It uses Bluetooth LE technology for communication with the smartphone applications (up to 50’ range). Without the limitations of being physically connected, the user can move about the workspace as needed with their smartphone and run the various apps while still using the phone for on-the-job communication. The device’s five pin XLRF connector/cable assembly allows it to be connected to a point in a DMX data chain to test or control of the various DMX/RDM functions. It is charged using a standard USB to Micro-USB cable and charger. Other features include a built-in LED flashlight, an audible alarm for locating a misplaced unit, XLR5M to XLR5M Turnaround, LED status indicator, and a removable belt clip with a split ring safety point. Optional accessories include XLR5M to RJ45 Adapter, XLR5M to XLR3F Adapter, XLR5M to XLR3M Turnaround, and a Belt Pouch.

Bugs squashed in record time. I sincerely appreciate the professionalism of City Theatrical’s dev team in rectifying a nasty bug that was making the text garbled.

I hope, in the future, City can expand the functionality of their app in the following areas:
- nameable DMX groups (submasters)
- allowing third party apps (either completely separate from this app or inside this app) to allow users to create custom interfaces/functionality that City might never think of.

Developer Response

Thank you for the bug reports you have submitted. Each report helps us identify and resolve bugs. We have submitted an app update to resolve the character bug which will be released as soon as it is approved by the App Store.

Powerful Tool


This app and device are a game changer. No dragging out the old console to repair fixtures. I use this everyday at work as a bench tech.

I have only one small request... I like to use the app on my iPad because of the larger wheels and faders. Please please please let the app rotate to landscape view. I frequently use the app while my iPad is connected to a keyboard. I have gotten used to just using the app sideways, but is a bit annoying.

Norby9k, Thank you for the review. I have submitted your request to our software team to work on. Please reach out with any additional problems.

Good app and tool


Overall very nice. I'd like to see next/last buttons in the fixture tool.

I'd also like to be able to optionally sort the RDM list by DMX address, too.

The fixture manual lookup is awesome.
