Indication
D1 (Green)
Located at the top left of the board serves as an indicator that 5V or 3.3V dc
is available to the daughter board connector, J2. Supply voltage 5V or 3.3V to the
daughter board is selected via the placement of fuse F6 (3.3V) or F5 (5V)
D3 (Green)
Located on the top middle of the board, labeled ‘FIBER’, provides an indication that
the transceiver module has detected the presence of an input signal on the fiber link.
When ‘ON’ indicates that this board has a good level of received optical power from
the remote unit.
D6 (Green)
Labeled ‘2.5V’, located on the mid-right of the board. When ‘ON’ indicates the on-
board 2.5V converter is operational
D7 (Green)
Incorrectly labeled ‘3.3V’, located on the bottom center of the board. When ‘ON’
indicates that 5V is available to the display LED ribbon header.
D8 (Green)
Labeled ‘5V’, located on the lower right of the board. When ‘ON’ ind5V dc
is available to the board.
D9 (Green)
Not labeled, located at bottom center of the board. When ‘ON’ indicates 3.3V is
available on the board.
D31 (Green)
Located on the left middle of the board, section labeled ‘VID #1’, provides an
indication of the presence of an input signal on video channel #1. When ‘ON’
indicates that this board has approximately 1.0Vp-p input signal (either video or
analog signal).
D32 (Green)
Located on the left middle of the board, section labeled ‘VID #2’, provides an
indication of the presence of an input signal on video channel #2. When ‘ON’
indicates that this board has approximately 1.0Vp-p input signal (either video or
analog signal).
D35 (Green)
Located on the left bottom of the board, section labeled ‘VID #3’, provides an
indication of the presence of an input signal on video channel #3. When ‘ON’
indicates that this board has approximately 1.0Vp-p input signal (either video or
analog signal).
