    Why is nothing displayed on the Omron Touch terminals screen?
    • J
      John FlowersSep 18, 2025
      If nothing is displayed on the Omron Touch terminals screen, it might be because Screen No. 0 has been read at the host side. Try changing the screen number. Alternatively, the system startup waiting time may not have elapsed yet; the display should appear after the waiting time is over.
