I use DW-U10a external model. Model No. is DVM-4222IU2. But I can't find any converting tool or firmware. All links are dead. If you have DW-U10A_to_DRU-500A.zip file please mail to me for update. My email address is hugyou@netian.com Who use external model? Best Regards.
I am trying to use the DRX500UL but can't get XP to recgonise it for longer than 30 seconds before it dissapears. I also have the DW-u10a on order so will let you know how I get on.
