LK204-25-USB-WB Lights on, logo shows but not found

Post by digitalthinker »

When I try to update the firmware the device does not appear. When I use LcdStudio the device is not found. I downladed the correct drivers and Windows 7 says the device is functioning properly, but I can't get anything other than the Matrix Orbital logo and text.

Hi digitalthinker,

Unfortunately, you will not be able to upgrade the firmware of your LK204-25-USB, but you should at least be able to communicate to the unit. The logo and text tell me that the display is power correctly, and the device manager seems to indicate that the USB drivers are working correctly. So it may be that the baud rate of this unit is set incorrectly.

Please follow the manual override procedure listed in your manual to temporarily return the unit to default settings. Then use LCDStudio to try to detect your unit. If successful use the scripting feature to send the numeric bytes listed in your manual to set the baud rate to a desired value. If not successful, please let me know and we'll try something else.

Thanks,
Troy
