View on the diagnostic LEDs
The 5 Cable Input board is located inside the Input & Communication unit. Only the LEDs at the front side (cover plate) are visible
without opening the projector. To view the other diagnostic LEDs the Input & Communication unit has to be placed in the service
position as illustrated below (moved forward and tilted). The other LEDs are then visible through the grid at the sides of the Input &
Communication unit.
C
AUTION
:
Only operate the projector for a few minutes while the Input & Communication unit is moved and
tilted in it’s service position. This to minimize the risk of exceeding the maximum permitted internal temper-
ature limit due to insuf
fi
cient air
fl
ow.
Description of the diagnostic LEDs
Ref. Description (LED
color)
Comment
1
INTERRUPT REQ (red) This LED lit up when an interrupt requirement arise.
2
DCM CLOCK OK
(green)
This LED lit up indicating that the output clock of the DCM is stable.
3
GP_LED3 (red)
(not used, future expansion).
4
CONV ADC
SELECTED (green)
There are two AD convertors on the board, ADC98001 and ADV7802. This LED is to indicate
which AD convertor is used. This LED lit up incase the ADC is used and otherwise ADV is used.
5
SYNC (yellow).
This LED lit up when a valid and stable input sync is detected for the applied source.
6
SEL (green).
This LED it up when the 5 Cable input is selected. There are three data streams output from the 5
Cable board to the PMP board. Namely: ADC, ADV and test pattern. This LED lit up in case ADC
or ADV data is selected to PMP. Otherwise internal test pattern is selected.
7
FPGA CONFIG (red).
This LED lit up during the start up of the 5 Cable Input and in case the FPGA of the 5 Cable Input is
not correctly loaded with the
fi
rmware. If this is the case try to reload the
fi
rmware and/or software
of the 5 Cable Input. If the problem remains replace the 5 Cable Input board.
8
+5V OK (green)
This LED lit up in normal condition and indicates that the +5V supply voltage from the Power
Backplane is available. The +5V is derived from the +12V which is generated by the Power Box.
9
+12V OK (green)
This LED lit up in normal condition and indicates that the +12V supply voltage from the Power
Backplane is available. The +12V is generated on the Power Box.
