Using the Terminal Interface via Serial Port

The terminal interface can be accessed via the serial port for configuration of the

basic settings of the CABCONS1716I. While not intended to be a substitute for the

Web interface, it does allow you to configure similar functions. The menu list below

describes the options that can be modified through the terminal interface.
NOTE: You must use the W option to confirm 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 traffic is tunneled through the SSH

connection andth VNC session is encrypted. Each method will be discussed briefly 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 configuration 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.
