Converting .ARW to .TIF and force 16 bit

The conversion of one .ARW file to another is straightforward:magick DCS0001.ARW DSC0001.TIF works well, but the output tif file is 48 bit, and I need 16 bit. What argument should I add? Next, when trying the globbing command:
magick *.ARW *.TIF or convert *.ARW *.TIF it seems that the cmd is working but nothing happens until I kill the command line(Windows 7).

Thank you
