Plug-and-play DMX to Serial (RS-232) signal converter for lighting systems.
The user needs to integrate a DMX-controlled system with an older system that uses serial commands. This is a frequent challenge in professional A/V, theater, and venue setups where legacy equipment is still in use.
Product Suggestion: A dedicated device, a 'DMX to RS-232 Smart Converter'.
Product Description: This device serves as a bridge between DMX512 lighting control systems and devices controlled via RS-232 serial commands. Key features include:
- DMX Input: Standard 3-pin or 5-pin XLR connector for receiving DMX signals.
- RS-232 Output: Standard DB9 connector or terminal block for sending serial commands.
- Configurable Mapping: An intuitive interface (e.g., USB connection to a PC, web interface, or on-device display with buttons) to allow users to map specific DMX channel values (or ranges) to specific RS-232 command strings. For example, DMX Channel 1 at value 255 could trigger "POWER ON\r\n" to be sent via serial.
- Addressable DMX Start Channel: User-configurable DMX start address for the converter.
- Robust Enclosure: Suitable for professional/venue environments.
- Power Supply: Standard external power adapter.
Target Audience: System integrators, venue technicians, theater electricians, and A/V professionals managing installations with a mix of DMX and legacy serial-controlled equipment.
Expected Benefits & Revenue Potential:
- Solving a Niche Problem: Directly addresses a specific technical challenge faced by professionals, allowing them to integrate modern DMX control with older, often expensive, serial-controlled equipment (e.g., projectors, specific lighting fixtures, media servers, show control systems).
- Extended Equipment Lifespan: Allows users to continue using valuable legacy equipment that is still functional but lacks DMX control, saving significant replacement costs.
- Simplified System Integration: Centralizes control under the DMX system, streamlining operations.
- Premium Pricing: As a specialized B2B hardware solution for a professional market, it can command a premium price (e.g., $150 - $400 per unit) compared to DIY solutions, due to its reliability, ease of use, and support.
- Recurring Revenue (Potential): While primarily a hardware sale, there could be opportunities for paid firmware updates with new features or custom command library support for specific devices.
- Market Demand: While niche, the problem is common enough in older or budget-constrained venues that a well-marketed product would find customers. The existence of DIY solutions (like Arduino-based ones mentioned in the comment) indicates the need, but many professionals prefer off-the-shelf, reliable products.

Converting DMX to Serial/RS-232
Posted by u/ted_anderson•06/10/2025
I have a functional DMX lighting control system in my venue and I want to use it to trigger a non-DMX lighting control system. This other lighting system is controllable via serial commands.

Did you even google DMX input to Arduino?
The only gotcha is that inputting dmx is done via a serial connection and:
"
Most basic boards like the Uno and Nano have only one hardware serial
