The PacED64 ships from Ultimarc with a pre-programmed flash routine on it that fires all all outputs simultaneously and can blow the virtual output board upon initial start if not cleared.
To clear the flash routine of the demo program, download the PACLED64 utility from Ultimarc found here... https://www.ultimarc.com/PacLED64.exe and install it (you will need microsoft .Net installed as well).
Connect the PacLED64 and run the PacLED64 utility and change to the Brightness tab and make the changes shown (set LED number to 0 for all).
Return to the settings screen and click on start recording. Let the recording run without changing anything for several seconds and then click on Stop. This will record a bliank pattern into the pacled64.
Click apply and exit the utility.
Further instructions on using the PacLED64 utility can be found here..... https://www.ultimarc.com/pacled64.html
As I can no longer find the time to combat the continued attacks on the forums they will be closed over the next few weeks. Assistance emails can be sent to support@zebsboards.com however, please be patient as I am currently focused on efforts to get the store functioning properly. Thank you for your understanding.
