Our customers have used variations on this design to drive the internal shutter of every modern large-frame video projector – including Barco, Panasonic, Christie, and Sanyo. It’s also possible to control video projectors, video switchers, DVD players and other production gear with this interface.
The DecaBox chassis makes this sort of interface very simple to implement.
All we need from you is a link to the instruction manual for your gear and a list of the commands you’d like implemented. We’ll take care of the rest.
Serial data strings of any length and baud rate can be accommodated. This means that we can generate simple control strings. For example:
- If DMX Channel 1 > 80%, output text ‘SET SHUTLVL 0’ open internal shutter
- If DMX Channel 2 = FF then output text ‘SET INPUT 3’ choose VGA input #3
We can also generate ‘live’ cues which are related in some way to incoming DMX channel values. For example, some show control systems can accept arbitrary serial input for triggering cues. So we build a simple command which chops a specific DMX channel value into 5% chunks, then transmits a unique serial string:
- 0% n/a
- 1%-4% “Cue 1 Go”
- 5%-9% “Cue 2 Go”
- 10%-14% “Cue 3 Go”
System includes a USB port for easy field updates and firmware changes. To edit the system’s personality, we send you a small .zip file, inside which is an .exe which will run on any modern Windows computer.
Interested? Email or phone us and describe your situation. We’ll make sure the gear leaves our shop ready to work perfectly the first time.
Price starts at just $265.
We can usually ship these systems the same day or – or worst case, the next morning. Overnight delivery and international shipping is no problem.
- DMX In & Through on XLR-5 connectors
- DMX input section is optically and galvanically isolated from the rest of the system for your safety and protection.
- RS-232 port generates industry-standard RS-232 levels for clean, consistent control.
- 2 line x 16 character LCD for system messages / user interface
- 3 ‘soft’ keys for input and parameter setting
- 3 LED indicators for status display
System power supply is 9-12V DC, 300 mA, center positive, with a commonly-available 2.1mm barrel jack. Units shipped to North America include a free ‘wall wart’ type power supply.
A few happy customers sent in reviews of their DMX – Serial Converters:
“Engineering Solutions Inc. had a product we needed at a great price but what really made us happy is their customer service and support. They were able to accommodate our very tight project schedule and custom programming needs without batting an eye and were great on follow up.
They’re definitely part of the solution.”
In June ’09 I contacted Response Box (Engineering Solutions) to request a DMX to serial converter. I needed a specific output setup to match Pioneer industrial DVD player V7400s.
The whole process from initial contact to receipt of the unit took only about a week. The unit sent to me matched my specific needs precisely and it work flawlessly from the first time I plugged it in.
John from Engineering Solutions stayed in frequent e-mail communication with me to assure he programmed the unit properly. When he mailed the unit he contacted me offerring to give installation advise.
Turns out I needed no advise because the unit was so easy to operate. And I really appreciate knowing that the unit can be reprogrammed via the Response Box pros by e-mail attachment and usb connection.
John offerred more than just advise, he also offerred to construct connection cables for me according to my project’s specifications.
Engineering Solutions was friendly, helpful, efficient, communicative and very competent in dealing with me. The price beat a Danish company making similar units by about $300.00, and beat Lanbox by about $450.00.
I will definitely use Engineering Solutions again when needed…and I highly recommend them to other audio/video artists, studio/stage producers, and engineers.

In our business, when you encounter a problem, you need a solution quickly. That is what Engineering Solutions did for us, analyze our problem, think of a solution, and ship it out. Within 36 hours we had this nifty little box that did the trick for us: controlling the lamps of a Barco CLM HD8 projector.
I’m looking forward to think out other crazy connexxion stuff with Engineering Solutions,
John, you saved the day.

I was commissioned to deliver animation and a video control system for a 12 month theatre production tour. The producers wanted everything to be triggered from the lighting desk so I Googled for a DMX to Serial converter to send control codes to a solid state video replay device.
I found John Chapman’s solution for a video shutter control that seemed to send a limited range of serial commands so I emailed John to see if that could be adapted to trigger up to 25 serial strings to play up to 25 different videos. John responded saying there was no problem adapting it to my spec and the price he quoted for two of these delivered to me in Australia was extraordinarily reasonable.
After more testing I found I could also make videos loop with a different serial command and after a couple of emails John happily accommodated the revised spec. My client was late giving approval but still kept the same delivery date (of course) but John was still able to deliver the DMX-Serial boxes on time.
Once we had them in the theatre we needed to make a small adjustment to how the DMX messages were handled but thankfully John had implemented a USB firmware update process. Within 24 hours John had sent me the new code and I was easily able to apply update.
The whole process has been a delight, John was unbelievably responsive and professional and I can’t recommend his company too highly. To arrive at a solution like this with John 1/2 a planet away via Google, email, UPS and never having met has been nothing short of very impressive.

Gateway Church is a large Church in Southlake Texas. Our attendance this past Easter 2008 was 16000 people. We had a need for a DMX to Serial device that would allow us to control one of our projectors with our lighting board.
I called Engineering Solutions and I was blown away.
This company delivers an awesome product that has nailed our application and need. They are fast, customer friendly and reliable.
Engineering Solutions completely exceeded my expectations and I will use them again.

Thank you for all the help in getting a dmx to serial converter created and programmed for my install. The timeline was short and I felt a little unsure about going down that path, thinking that a standard servo dowser would be a safer choice. After our initial discussion about my desired product however, I felt completely at ease with the idea, and was certain of your ability to get me exactly what I needed. The box was perfect, and the custom programming works like a charm. The clients absolutely LOVE the silent nature of the internal shutter that we now have control over, and the ability to remotely turn the projector on and off, and to select different inputs. Everything can now be programmed into the show as needed by the lighting designer.
The client, and I, couldn’t be happier. I look forward to working with you on future projects. It’s also great to have a collaborator for designing high end custom pieces for each new need.
