The Status panel indicators show the current state of the DLPC900. When any of the boxes are checked, this indicates the stated text has occurred. Any boxes that state an error and remain checked must be corrected before continuing to operate the EVM.
The following is a description of each status indicator:
- Internal Memory Test Passed – The DLPC900
performs an internal system memory test at
power-up. The box is checked if the test
passed.
- Controller/DMD Incompatible – The box is
checked if either the controller or DMD are
incompatible with the firmware including loading
incorrect firmware or an issue with communication
between the controller and DMD. Check for possible
damage to the SCP lines, or damage to the flex
cables. Also ensure that the DMD is sitting
properly in the socket, and is not missing or
damaged.
- Secondary Present and Ready – The box is
checked when the GUI is connected to a DLP
LightCrafter Dual DLPC900 EVM. If the GUI is
connected to a DLP LightCrafter Dual DLPC900 EVM
and the box is not checked, then one or both of
the DLPC900s are potentially malfunctioning or the
EVM was incorrectly programmed with a Single
DLPC900 firmware file.
- Internal Initialization Complete – The box is checked when all power-up initialization routines have completed and passed.
- DMD Reset Waveform Controller Error – The
box is checked whenever the DMD Reset Controller
has found multiple overlapping Vbias or reset
operations accessing the same DMD block of
micromirrors.
- Forced Buffer Swap – The box is checked
whenever a forced buffer swap occurs. This error
can occur if the DLP LightCrafter Dual DLPC900 EVM
is set to Video Mode and the vertical back-porch
timing is too small. The error can also occur if
the DLP LightCrafter Dual DLPC900 EVM is set to
Video Pattern Mode where the patterns are from the
video port and the pattern sequence timings do not
match the video port VSYNC - specifically the
cumulative exposure times are greater than the
frame time. Forced buffer swaps may also occur
during any of the pattern modes in preparing a
pattern sequence and the timing of a status read.
The user may need to perform additional reads of
the status to get a correct state of this
indicator. If the box continues to be checked,
check for an error condition in the pattern
sequence.
- Sequence Abort Status Flag – The box is
checked whenever a sequence abort has occurred.
Sequence abort may occur during any pattern mode
in preparing a pattern sequence and the timing of
reading the status. Additional status reads may be
needed to get a correct state of this indicator.
If the box continues to be checked, check for an
error condition in the pattern sequence. Also
check that the cumulative exposure time is not
greater that the frame time.
- Sequence Error – The box is checked
whenever a sequence error has occurred. Sequence
errors may occur during any of the pattern modes
in preparing a pattern sequence and the timing of
reading the status. The user may need to perform
additional reads of the status to get a correct
state of this indicator. If the box continues to
be checked, check for an error condition in the
pattern sequence.
- DMD Micromirrors Parked – The box is checked whenever the DMD micromirrors are parked.
- Sequencer Running – The box is checked whenever the sequencer is running.
- Video Running – The box is checked whenever video is running normally.
- Locked to External Source – The box is
checked to indicate that the EVM has locked
to an external parallel RGB video source. If the
EVM loses the locked signal at any time, the box
becomes unchecked. A locked source must be present
to switch to Video Pattern Mode.
