Option Description
Enabled: This option enables the Access options described below. 
Note: If the Master Security check box is not enabled, all subordinate options are grayed-out and 
not selectable, meaning that the Master is completely unsecured and can be altered by any user 
(regardless of their rights).
Terminal (RS232) 
Access: 
If selected, a valid username and password is required for Terminal communication via the 
Master’s RS232 Program port. 
HTTP Access: If selected, a valid username and password is required for communication over HTTP or HTTPS 
Ports, including accessing the WebConsole.
Telnet/SSH/SFTP 
Access:
If selected, a valid username and password is required for Telnet Access. Telnet access allows 
communication over either the Telnet and/or SSH Ports, and Secure FTP access.

To establish a secure Telnet connection, an administrator can decide to disable the Telnet Port and 
then enable the SSH Port. 
Refer to the Port Settings section on page 54 for details.
