DLP4500: DLP LightCrafter 4500 control softWare cannot connect the projector through USB

Part Number: DLP4500
Other Parts Discussed in Thread: DLPC350

Hi,

I connected a DLP LightCrafter 4500 to Windows 10 PC with a mini USB cable, but DLP LightCrafter 4500 control softWare cannot connect to the projector ,the software (version:v3.1.0) couldn't detect the the projector automatically(It worked well just a few days ago). The red dot on the "Connected" button is always red. I have tried different USB cable but still cannot connect. However, the projector can be find in USBDeview(gives information about all the USB devices in using) as DLPC350. By the way, the projector can project vedio through HDMI normally.

How can I solve this problem?

Thanks,

Hello Yu,

Welcome to the E2E forum and thank you for your interest in DLP technology!

Have you attempted a system reset? The button is to the side of the "Connected" button.

Regards,

Austin

Yu,

You may want to start by seeing if you can isolate the problem.

Can you confirm that you have not tried to upload any new firmware to the device or modified the hardware? If so, you should check whether your USB cable has any issues.

Putting these aside, you may also want to try a different PC/OS if such is available. Has your setup changed since communication last worked?

Philippe Dollo,

I have tried something to isolate the problem ,whitch include,

1 I have changed usb cable,but Neither usb cable is working

2 I have tried another win 10 pc,but none of them can connect the projector

3 I can confirm that firmware has not been replaced or attempted to be replaced

4 GUI setup never changed since communication last worked

So,Is there any other way you can fix the problem.
