Diagnostics connector (J6).
NOTE: DIAGNOSTICS NOT AVAILABLE
D4 (Green)
Located at the lower right edge of the board serves as an indicator that the microprocessor is
receiving diagnostics requests from the diagnostics PC through the Diagnostics Header (J4)
or Diagnostics connector (J6). This LED will blink ON with a received request then OFF
with the next request.
NOTE: DIAGNOSTICS NOT AVAILABLE
D5 (Green)
Labeled ‘Q_OF’, located on the center top edge of the board, if “OFF” provides an indication
that the Ethernet to serial chip U8 is overflowing its internal buffer. Typically this LED will
always be “ON” – not in an error state.
D6 (Green)
Labeled ‘LOCAL’, located on the center top edge of the board, if “ON” provides an
indication that the programmable logic device U1 is receiving a system receive clock and
receiving data from the Daughterboard Header (J2).
D7 (Green)
Labeled ‘REMOTE’, located on the center top edge of the board, if “ON” provides an
indication that the programmable logic device U1 is receiving a system transmit clock and
outputting data onto the Daughterboard Header (J2).
D9 (Green)
Labeled ‘+3.3V’, located at the bottom right edge of the board serves as an indicator that the
on-board +3.3VDC power supply (U6) is working.
D10 (Green)
Labeled ‘W_TX’, located on the center top edge of the board, if “ON” provides an indication
that the programmable logic device U1 is receiving data from the Ethernet to serial chip (U8)
and outputting data onto the Daughterboard Header (J2).
D11 (Green)
Labeled ‘W_RX’, located on the center top edge of the board, if “ON” provides an indication
that the programmable logic device U1 is receiving data from the Daughterboard Header (J2)
and sending it to the Ethernet to serial chip (U8).
D12 (Green)
Labeled “P5 LED1”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
D13 (Green)
Labeled “P5 LED2”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
D14 (Green)
Labeled “P5 LED3”, located at the lower right edge of the board serves as an indicator that
data is being sent between the Ethernet Switch chip (U4) and the Ethernet to serial chip (U8).
NOTE: THIS FUNCTION IS NOT AVAILABLE
