USB/RS232 Fader Start Interface

USB/RS232 Fader-Start Interface

This USB/RS232 Interface offers 10 inputs which work with my DAC Cartwall and StudioScreen applications plus mAirList and Myriad Playout v5/v6.

Unlike a keyboard, this means that the software does not have to be “in focus” on your computer to receive the commands.

Image shows older “Joystick” interface, but same layout: 10 sockets on rear, USB socket on opposite side.

Click here to see the Command Mappings text file showing the functions supported – just let me know which software you’ll be using it with (they are NOT user-programmable!).

mAirList also permits .mls scripts to be run from this interface, which is handy if you have a special “remote-start” script – perhaps you want the fader-start buttons to be Player Start/Stop in Live Assist but all set to Automation 1 On;Automation 1 Next when Automation is enabled. eg: If each button ran a mAirList script file instead of a Player action, then you could change the commands simply by editing the script file – allowing for instant reprogramming.

Special commands can be processed via a Notification Script (see this example), reacting to “OnSerialData” event-triggers also permitting instant reprogramming while mAirList is running.  Other commands can be programmed before shipping – any valid command syntax (or chain of commands) can be specified if you have a special requirement. Available commands in mAirList are available as a dropdown in the “Remote” section of the Configuration program.

Myriad Playout contains an HTML file of the available commands via the “Command Processor” engine.  You do *not* need to run their Hardware Service to use this interface box.

  • USB/RS232 Interface, self-powered
  • 10 momentary button inputs on 6.35mm sockets (1 press = 1 action, long press does not “repeat”)
  • Includes 1m USB cable (input socket is “B” style, like most printers) plus instruction sheet
  • Size: 100x100x50mm

STOCK STATUS, 12-April : 1 UNIT AVAILABLE
I produce these myself, in small quantities, when I have time – they may not always be in stock.

Price includes 1st-Class “Signed-For” / EU Tracked+Signed shipping.  Once I see your payment, I will be in touch via e-mail to confirm any special programming requirements and then a tracking number once shipped, normally within 1 working day.

STILL AVAILABLE: I also have 1 of the “Joystick” versions left – same box, just different interface and will work with a number of playout applications.  Button assignments are defined by the software, so you can adjust what each input does yourself – This version is slightly cheaper, details are at the bottom of this page.


USB Interface FAQ
Here are some popular help/tech tips for this interface…

Remote-Start Wiring Diagram

  • How do the remote-sockets work?
    Just short the tip/centre to the outer/sleeve/ground – A simple push-to-make connection. The sockets are stereo, so it won’t matter if you use mono plugs.
  • Can I re-program the Buttons?
    To change the “command actions” of a button requires editing the source-code of the software, compiling it to a HEX file and uploading into the unit. I can supply a new HEX file for you to load via a simple Windows utility.
  • Does this work with xxx playout software?
    No. These boxes, although able to generate any RS232 string, are being sold exclusively for DAC Cartwall, StudioScreen and mAirList+Myriad Playout, they cannot be programmed “ad-hoc” by the user.
  • How do I use this with a Behringer DX2000USB?
    Just add 5x 1/4″ (6.35mm) stereo patch leads – available from CPC . This will give you button-start on the 5 stereo channels without having to do any soldering or looking for special custom cables.
  • Do I need any wiring or soldering skills?
    Probably not, especially if your mixer uses 1/4″ sockets for the remotes. Some broadcast desks use 9-pin sub-D connectors – these are readily available from CPC/RS etc. Please consult your mixer handbook in the first instance. I do not make/sell these cables.
