DLPDLCR4710EVM-G2: how can I install batch file into non-volatile memory?

Part Number: DLPDLCR4710EVM-G2
Other Parts Discussed in Thread: DLP4710EVM-LC

Hi, how can I install batch file into non-volatile memory? 

I want to use the DMD without connecting LED, but by default, the firmware expects there to be LEDs connected, so module will not power on correctly if it detects that these LEDs are not present.

When the LED is connected, I can turn on the DLP then click 'advanced' button on the GUI and add batch files. But when I disconnected the LED, then turn on the DLP and try to write batch file to tell the DLP that I want to use DMD without LED( W 36 52 00), it doesn't work.

So I need to change the batch file before I turn the DMD on, but how can I do that? 

looking forward to your response, thanks so much

  • Hello Haoxiang,

    Welcome to DLP forum and thank you for your interest in DLP technology.

    Could you please share more details about your application and use case? This will help understand your  requirement better and offer a solution.



  • HI, the EVM software version is 4.1.0, firmware is 7.3.2 and the GUI version is 7.4

    I want to use the DMD inside this DLP as a spatial light modulator, use is to change the phase and amplitude of the external input laser. So I need to unplug the LED, cause I don't need that.

    So I just wondering how to add batch files to make the DLP disable the LED once it's turned on, otherwise it will found that LED is missed and won't be turned on correctly. If I run the batch file in the advance mode, it will not disable the LED permanently, which means every time I need to run this batch manually after I turned it on, but if the LED are unplug, it can't be tuned on without using batch file. 

    SO  how can I install batch file into non-volatile memory to disable the LED permanently?


  • Hello User,

    Unfortunately, we do not support the use case of disconnecting the LED's from our EVMs. However, you might consider the DLP4710EVM-LC as it will give you better control for exposure times which will be useful for your end application. Please do note though that it will not be possible to have the LED's removed from this use case either.

    Thank you for understanding.
