Uemis SDA to Subsurface

[Simon]

Hi,

  I have a problem with my dive computer, UEMIS SDA, to connect with 
your subsurface software.

-I can´t find a PC Mode on my SDA -> in the UEMIS manual didn´t exist a 
PC Mode -> get the USB cable with the dive computer and the pc, that´s it!
-my subsurface is the newest / 4.6.3
-the dive computer firmware is new
-my windows PC has windows 8
-my SDA is a storage device at the windows file exploder
- at the subsurface menu - File - configure dive computer - device or 
mount point -> is only the COM1 / no USB device

?????


best regards and many thanks for your work

Simon
