Texas Instruments DLP LightCrafter 4500 User Manual

PC Software www.ti.com
• Forced Swap: When highlighted red, the DLPC350 sequencer detected a forced buffer swap error
indicating that image data has been displayed from the wrong internal display buffer. When highlighted
gray, no buffer swap error has occurred. This error can occur if the DLP LightCrafter 4500 is set to
Video Mode and the vertical backporch timing is too small. The error can also occur if the DLP
LightCrafter 4500 is set to Pattern Sequence mode with patterns input from the video port and pattern
sequence timings do not match the video port VSYNC.
• Sequencer Error: When highlighted red, the DLPC350 sequencer has detected an error. When
highlighted gray, the DLPC350 sequencer detected that no error occurred.
• DMD Parked: When highlighted yellow, the DMD micromirrors are parked in the position normal to the
DMD plane. When highlighted gray, the DMD micromirrors are not parked.
• Buffer Freeze: When highlighted yellow, the frame buffer is frozen. When highlighted gray, the frame
buffer is not frozen. This is cleared on the next buffer swap.
• Sequencer Abort: When highlighted red, the DLPC350 sequencer has detected an error condition that
caused an abort. When highlighted gray, the DLPC350 sequencer detected that no error occurred.
These indicators are updated every 2 seconds, or when a command is issued to the DLPC350.
• Auto Update Status. When checked, all indicators will continue to update every two seconds. When
unchecked, the indicators will stop updating and turn gray. While running in Pattern Sequence Mode,
keeping the option unchecked prevents the GUI from interrupting the DLPC350 controller which will be
processing critical functions related to pattern display.
3.2.2 Operating Mode
To the right of the System Status, the Operating Mode sets how the DLP LightCrafter 4500 operates:
• Pattern Sequence mode: The DLPC350 takes 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit data from one of the
following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Flash memory
The DLPC350 does not apply any video processing functions and provides a pixel accurate mode
where every pixel maps to the native DMD resolution of 912 × 1140.
• Pattern Sequence [Variable Exposure] mode: The DLPC350 takes 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit
data from one of the following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Flash memory
This mode differs from Pattern Sequence mode in that the pattern exposure time and pattern period
can be varied per pattern in the pattern sequence.
The DLPC350 does not apply any video processing functions and provides a pixel accurate mode
where every pixel maps to the native DMD resolution of 912 × 1140.
• Video Mode: The DLPC350 takes 24, 20, 16, 10, and 8-bit data from one of the following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Internal test pattern generator
– Flash memory
The DLPC350 then applies video processing functions, such as scaling, gamma correction, and color
coordinate adjustments, and sends the processed image to the DMD.
• Power Standby: Places the DLPC350 in low-power state and powers down the DMD interface.
