Design Considerations

LED_L indicates the combined link and carrier sense signal (LED mode 1 of the DM9000A),

or only the carrier sense signal (LED mode 0).

5.4. Display

When designing a housing for the Panel-Card 57/70, care must be taken. The touch panel

has a very sensitive area which should not be pressed to prevent performance degradation

or malfunction. Please consult the manual of the corresponding displays.
