Once the password is authenticated, the user can access all web pages with re-entering the password
until the web browser is closed.
NOTE
If the passwords are forgotten, there is not an administrative (backdoor) method of discovering them. You need to
clear all passwords by resetting the configuration settings. See
HTTPS Encryption
Check this box if you wish to encrypt the transmission between the browser and the web server. The Secure SSL
(Secure Sockets Layer) protocol, supported by all modern browsers, is used to connect to the web page. This
protocol encrypts all data transmitted between the PC browser and Janus controller including username and
password data required to make the connection.
When using HTTPS encryption, the user must accept a security exception the first time a web browser attempts to
connect to the web server. This is required because trusted SSL certificates cannot be issued for hosts with
changeable IP addresses
–
as is the case with the Janus controller.
Click on the
A

button to apply settings. A confirmation message should be displayed indicating that the
controller must be reset in order to update the configuration parameters. You must acknowledge this message to
continue.
