hey all ... i was installing a new image using flash to my DM500S it was the new PLI image ... anyhow the process stuck at 83 % percent for a long time so i unpluged the power cable and reconnect it ... now ofcourse the DM doesnt work .. it doesnt have an ip address so i cant use normal programs ... my pc doesnt have a vaild null modem port .. i bought a usb to serial rs232 converter but when dreamup tells me to connect my DM and i power it on no connection is valid .. does that mean that my converter isnt workin or my DM is dead .. plzzz help
