Benefits and Improvements

  • Fixes issue when displaying a non PC source and sending the power off command via RS232 that caused the unit to switch to the PC source instead of turning off. Now the unit will shut down regardless of what source is being displayed
  • Added an “AutoSource” menu item that will turn off the auto source feature. When set to OFF, it will no longer change to a newly connected/turned on source, it will remain on the initial source. When turned back on, the panel will change to any newly detected sources. Default value is ON
