No. 1790	Re: Powersupply	2021-03-04

Dear Stefan, Probably the device was entered other operation mode, not a power supply issue. For most of ezTCP products: When all the LED blinks at the same time, that indicates the device is in Serial Configuration Mode. When the red LED (PWR) is on and the others are off, that indicates the the device is in ISP mode. So, You can get the device back to Normal Mode with some simple steps. For better support, could you please tell us the the device model that is having the issue. Thank you, Best regards, Khanh > Stefan Richter wrote: > ------------------------------------ > Hallo, when I plug in the power plug, the red LED blinks or is on and the other LED are off. Is there a problem at the power supply. best regarts Stefan
