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 DMD SCP lines, or damage to the flex cable. Also verify 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
Single DLPC900 EVM and the box is checked then the DLPC900 is potentially
malfunctioning or was incorrectly programmed with one of the Dual DLPC900
firmware files.
- 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 Single 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
Single 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 can also occur during any of the pattern modes in preparing
a pattern sequence and the timing of a status read. There is a possibility that
the user needs to perform additional reads of the status to get a correct state
of this indicator. If the box continues to be checked, then 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 can
occur during any pattern mode in preparing a pattern sequence and the timing of
reading the status. Additional status reads can be needed to get a correct state
of this indicator. If the box continues to be checked, then 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 can occur
during any of the pattern modes in preparing a pattern sequence and the timing
of reading the status. The user can need to perform additional reads of the
status to get a correct state of this indicator. If the box continues to be
checked, then 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.
- 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.
-
DLPA200 Fault – The box
is checked whenever a DLPA200 fault has occurred. The
box is active when a DLP5500 DMD is connected.
-
DMD Communication error
– The box is checked if the controller is unable communicate with the
attached DMD.
