Other Parts Discussed in Thread: DLP4500, DLP4710, DLPC3479
Hello,
we want use the projector for 1D 8bit pattern with a long exposur time.
When using the internal pattern mode in the standart GUI we can set the exposur time to any time we want.
But for exposur times above 18ms we get result in a lower qulity. The displayed picture has bolow 8 bit and the qulity lowers with a higher exposur. For around 50ms we get a 1 bit result.
We measured the Trigger 2 and one LED output with an oscilloscope. The trigger is shown by the yellow line, the LED output by the blue line. When the exposur time is set to 18ms or bellow (picture 1) the LED signal has the same durration an the Trigger 2 Output. When the exposur time is set above 18 ms (picture 2 with 30ms) the LED shuts off after 18ms.
Why is the LED exposur time limited? For Thermal reasons?
Is there a way to extend the exposur time, either with a new firmware or by using another driver triggered by the Trigg 2 output?
We only have experience with the DLP4500. The DLP4500 is capable off very long exposur times.
We just startet using the DLP4710 EVM-LC, due to missing missing user guides we have porblems getting the projector rinnung the way we want it to. Is there an option of directr support, for example via zoom, microsoft teams or other conferenc call systems?
Kind Regards
Lennart
