Connection and Display Checks
Either Gigabit port can connect to the sender or another receiving card. D1 flashes during normal operation; rapid D2 flashing indicates that Gigabit has been recognized and data is arriving. The card also provides connections for external run and data indicators.
Use the integrated test button to check brightness uniformity and module flatness. Smart settings configure the screen-unit alignment. The original listing and the PDF give different voltage ranges and working-temperature limits, identified separately above. The specification recommends a standard 5 V supply. Confirm the limits applicable to the supplied hardware before installation.
