9.1 How to manage access to the AsteRx SB Sx

User Administration

By default, all communication interfaces are assigned
User-level access as shown in Figure 9-1.

level allows full control of the receiver while

Viewer

n the example shown in Figure 9-2:
Web Interface:
Anonymous users (without password) can connect to the receiver via
the web interface as Viewers. They can browse the various windows but cannot change
any of the settings. Only George, who has User access, can change receiver settings via
the web interface.
FTP:
Anonymous users have full access over FTP so can download and delete logged
data

IP, COM, USB, and Bluetooth ports:
Only George has User access to these ports so
can change receiver settings over these connections. Mildred has only viewer access,
so can only send commands to show the con
fi
guration. Anonymous users can neither
change or view the receiver con
fi
guration over these connections.
