    2. wget https://www.oceanphysics.org/support/Documents/Dtacq/soft/dtacq627-7apr25-fullstack16.tgz
    3. tar -xzf https://www.oceanphysics.org/support/Documents/Dtacq/soft/dtacq627-7apr25-fullstack16.tgz

   1. wget https://www.oceanphysics.org/support/Documents/Dtacq/soft/dtacq627-7apr25-fullstack16.tgz
   2. scp dtacq627-7apr25-fullstacq16.tgz root@dtacq:/mnt
   3. ssh root@dtacq
   4. cd /mnt
   5. tar -xzf dtacq627-7apr25-fullstack16.tgz
3. restore network configuration if fixed IP
4. perform final network configurations listed in /mnt/local/README
