SteveNZ Posted August 14, 2018 Share Posted August 14, 2018 Does anyone have any experience with how long the HUB75 cable can be? I have a P5 panel that I want to install on the top of the pinball machine so I need about a 0.9m cable. I made a cable and tested it but the display was very messy with waves and ghosting and other interference. This cable was about 900mm long I made a shorter cable about 200mm long and the extension panel worked perfectly. Link to comment Share on other sites More sharing options...
Rappelbox Posted August 14, 2018 Share Posted August 14, 2018 If you’re firm with a little soldering you can add 2x ls245 to switch to 5V level what the panels actually use. That should help Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted August 14, 2018 Content Provider Share Posted August 14, 2018 Keep the pin2dmd controller close to the panels and use a longer 14pin DMD cable instead. Link to comment Share on other sites More sharing options...
SteveNZ Posted August 14, 2018 Author Share Posted August 14, 2018 I could place the shield halfway between the standard DMD position and the extended DMD, then each of the 16pin cables would be about 500mm. However I think a more elegant solutions may be to boost the signals for an extension as suggested by Rappelbox. I'll do some testing with some LS245 chips and see what happens.
