Advice to self: RTFM
The following are valid for Manual Verson 4-548-269-13(2). See the upper right corner of the first page of the manual for the version number.
1. Sending a modified document to the server is described starting on p. 26
2. setting up the network drive and using it to download (synchronize) files is described starting on p. 64
I changed the settings on the server because it seemed to be downloading all the files on my Box.com account. The new settings are
Server:
https://dav.box.com/dav
Port: 443
Username: my username
Password: my password
Sync Folder: /SonyDPTS1
Destination Folder:
By following the instructions I have been able to download documents, modify them, and upload (synchronize) them to Box.com. The procedure seems to be convoluted and prone to overwriting modified files but it works if one is careful and
1. backs up documents on the Box.com account to a desktop computer
2. renames modified files on the DPTS1.
