Program layout and updates
The original series description lists real-time preview, overlapping regions, partition backgrounds, up to 32 gray levels and seven-color display. Timed content and LAN management support information signs. USB drives transfer programs, but the listed smart-settings function requires the network connection.
Temperature, humidity and brightness functions require the corresponding external sensors. Use the manual matching the selected card to check wiring and configuration.
