My program correctly runs in a computer window, but I can't save and apply the panel through USB, Controller TF s1/su, Password 168, Panel 96 X 16 Color R.
You might have to reach the developers because this procedure is nowhere explained. However, as far as I know for these devices you have t make sure that they're properly connected to the PC using the COM/USB ports in order to save settings.
Access the built-in Help section for Power LED and if you still have issues, visit the following link and report this issue to the developers: http://www.powerled.uk.com/contact/
