External power supply instead of micro USB port

Hi, how to provide power supply for PFM-M487 without micro-USB port? I've tried to supply power by connecting a voltage source(tried 512V) to VIN pin, but the LED on board even didn't light. I've tried to supply power by connecting a 5V voltage source to VCC, and the LED on board light, but the program didn't work as it did when connected to microUSB port.
