The 40 functions provided supply up to 80
communication objects for connecting to group
addresses.

used, you can also define a standard gateway
or router. This provides an option to contact
subscribers in the Internet or in another
network.
Access to the configuration and viewing of Web
pages may be password-protected.
A parameter can be set to determine whether the
user-defined settings, which can be made directly
from the Web configuration page, are to be
initialized or saved in the ETS download.
A parameter can be set to update to the object
values after a restart.
A parameter can be set to disconnect users after a
selected period of inactivity.
ETS is used to select the application program, assign
specific parameters and transfer this data into the
N151 IP Viewer.
