4.3.4 Status

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 cables. Also make sure 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 can also occur during any of the pattern modes in preparing a pattern sequence and the timing of a status read. 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 need 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 needs 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.
  • DLPA200 Fault – Only applies to the DLP5500 DMD and is grayed out for all Dual DLPC900 DMDs
  • DMD Communication Error – The box is checked if the primary controller is unable communicate with the attached DMD.
