How can I configure a TN3270E conection?

Is it enough if I put TN3270E:ip_address from the 
Administrator's Console ?

TN3270E is self-defining by the host you are connecting to.

So, you just want:

*TN3270:ip_address

Then, when connecting to the host, it goes "hey, do 
TN3270E?" to which Screensurfer replies "OK, yes, I'll do 
TN3270E".

Otherwise, the host starts asking if Screensurfer will do 
the Telnet options necessary to support standard TN3270 and 
goes from there.

The best way with our latest download is to use the 
connection wizard, which gives you a nice interface for 
determining which options work best for your host.

Then, take the connection string displayed in the wizard, 
and edit the global.stml, <TESECTION HOME> to update one of 
the links so that it uses the options displayed in the 
wizard.
