TB9400 Installation and Operation Manual Working with Base Stations from Your PC 49
© Tait Electronics Limited September 2011
4.2.3 Responding to Security Warnings
When your browser connects to a TB9400 for the first time, it raises a
security warning. Normally, secure websites have a security certificate issued
by a trusted Certification Authority. This is to foil attempts by rogue
websites to pretend to be something they are not. Obtaining such certificates
is impractical for each installed TB9400, so a self-signed certificate is created
when the reciter’s firmware is installed.
Your browser raises a security warning because the security certificate was
not issued by a trusted Certification Authority. The browser has a way of
letting you override or bypass the security warning. In Internet Explorer,
you install a certificate, in Mozilla Firefox you add an exception, and in
Google Chrome you elect to proceed anyway.
You can be confident that you are not connecting to a rogue website
pretending to be your TB9400, so follow the procedure below to tell the
browser that the security certificate is OK. The browser then stores the
security certificate and will not raise a warning on subsequent connections,
unless the IP address of the TB9400 changes or you use a different URL
such as https://127.0.0.1. For more information, refer to
http://support.microsoft.com/kb/931850 (Internet Explorer) or search for
“security certificate” in your browser’s Help.
Firefox 1. When the message “This Connection is Untrusted” appears, click
I Understand the Risks.
2. Click Add Exception.
3. The Location field includes details specific to your TB9400. Without
changing the default values, click Confirm Security Exception.
Internet Explorer 1. Click Continue to this website (not recommended).
2. Click Certificate Error.
3. Click View certificates. The Certificate dialog box, General tab is
displayed.
4. Click Install Certificate and then follow the Certificate Import
Wizard to install the certificate. Proceed to the end without changing
the default values. When the Security Warning window appears, click
Yes.
