Front Panel
Two bicolour LED indicators (PCB Rev. 0) or 4 green LEDs (Rev. 1 PCB) are provided as USB V
BUS
(+5V)
indicator, associated to the particular receptacles. Since V
BUS
is controlled by the USB driver software,
the LEDs are lit when a connector is ready for use. Vice versa, a LED is off if the respective USB port is
not initialized, intentionally switched off, or a short-circuit situation is detected, presented by the
connected device.
