    Are you grounding /USB PWR ENABLE?

    /USB_PWR_EN connected via a divider to the FT232RL on the QuickStart board.

    How are you attempting to externally power the Quickstart + W5200 board? Are you using the barrel jack on the W5200 board?

    Yes I use the QuickStart board + W5200 board for QuickStart. I connect the external power via jack on the W5200 board.

    1) Is the program loaded into EEPROM?
    2) Are you using the Parallax Serial Terminal to view debug information. If so, using the following PST initialization code block.
      if(ina[USB_Rx] == 0)      '' Check to see if USB port is powered
    outa[USB_Tx] := 0       '' Force Propeller Tx line LOW if USB not connected
  else                      '' Initialize normal serial communication to the PC here                              
    pst.Start(115_200)      '' http://forums.parallax.com/showthread.php?135067-Serial-Quirk&p=1043169&viewfull=1#post1043169
    pause(500)

    I can assure you the WIZnet Ethernet Board for Quick Start does run on external power.

    Yes, I load the program in the EEPROM.
    Yes, in the initialization block is the code.

    I load the standard example WebServer_W5200_RTC.spin.

    It works fine with powered USB, but with external power supply there is not any reaction.

    I'm not saying that the board W5200 does not work, I'm trying to understand the reason why is not working.

    WebServer_W5200_RTC.spin program does not work in the examples from external power.

    Writing to the terminal without the USB cable causes problems. I'm not sure why. I attached RTC code that will work without the USB cable connected. Sorry for the inconvenience.

    I'll have to consider using a debug flag to turn off the pst debug terminal.

    Thanks Mike G -- I had the same problem and the new code works. I can unplug the USB cable from the Starter board now. Good Stuff!
