Using the Terminal Interface via Serial Port
The terminal interface can be accessed via the serial port for conguration of the
basic settings of the CABCONS1716I. While not intended to be a substitute for the
Web interface, it does allow you to congure similar functions. The menu list below
describes the options that can be modied through the terminal interface.
NOTE: You must use the W option to conrm and apply any changes made before you
exit the terminal session.
The VNC Interface
There are three ways to communicate with the Server Remote Control unit in order to
control the host computer:
Web interface: The integrated Web server includes a Java-based VNC client. This
allows easy browser-based remote control.
Native VNC client: There are several third-party software programs that use the
standard VNC protocol, available in open source and commercial VNC clients.
SSH access: By default, there is a standard SSH server running on port 22 (the standard
SSH port). Once connected via SSH, the VNC trac is tunneled through the SSH
connection andth VNC session is encrypted. Each method will be discussed briey in
the following section. The type of encryption method or client used is not critical.
Web Interface
Using CABCONS1716I’s web interface requires a browser, with cookies and JavaScript
enabled. To launch the Java VNC client, login to the Web conguration interface and
click on the thumbnail of the desktop on the Home menu, or click on the Connect
button, located in the Main Menu.
You may need to upgrade Java support in your browser; however, most modern
browsers come with a version of Java that is compatible with this application. The Java
VNC client makes a connection back to the Server Remote Control unit over port 5900
(by default) or 15900, if encrypted. The encrypted connection is a standard SSL (Secure
Socket Layer) encrypted link that encrypts all data from the session, including the
actual video pictures.
Because Java is considered a “safe” programming language, the Java VNC client has
some limitations. Certain special keystrokes cannot be sent, such as “Scroll Lock” on
the keyboard.
This client software requires the use of Java 2 (JRE 1.4) to enable features like wheel
mouse support. Sun Microsystems’s Java site, http://www.java.com, is an excellent
resource to ensure your browser and operating system are updated accordingly.
