My step-dad has a matrix board with a control unit:

You can plug your laptop into the control box via USB (laptop end) to unknown connection (control box). Then you can program your own signs e.g. "wide load" or "slow down" etc. Does anyone know what the connector is or what cable is needed?

I suspect this may be the cable needed, but I am not certain:

  • \$\begingroup\$ Colin - Hi, I hope I have made the question clearer with my edit. Feel free to do any further tidy-up that you want. My brief comment about the question is this: Based on the (blurry) image on the linked page, I don't believe that the signal on that connector is USB (i.e. the programming cable is a USB-to-some-other-interface converter, which is then used on that connector). Even if you can find the connector; even if you can find the interface's electrical standard; how do you plan to actually program new text into the sign, without using the manufacturer's own software that you linked? \$\endgroup\$

  • \$\begingroup\$ Hi Sam thank you for your edit much appreciated, he has the software already but just not the cable and of course without the cable to connect it to the laptop to program it, he cannot add new signs, I'm not certain thatis the cable all I know is one end is USB and the other goes into that port on my questions picture I've seen them before but I've no idea what they are \$\endgroup\$ Commented Apr 2, 2020 at 18:43
  • \$\begingroup\$ Have you asked ledlightbars.co.uk if they can supply a (replacement?) cable, or if the cable/software you linked works with your sign? \$\endgroup\$ Commented Apr 2, 2020 at 18:49
  • \$\begingroup\$ Hi I have messaged them to enquire as to whether they can supply a cable which will do the job the matrix board was given to my step dad by a friend who had lost the cable \$\endgroup\$ Commented Apr 2, 2020 at 18:53
