Chapter 5. Usage Prerequisites The B050-000 features an embedded operating system and applications of fering a variety of standardized interfaces. This chapter will describe both these interfaces and the way to use them in a more detailed manner .
Chapter 5. Usage information on how to upgrade your browser to a state of the art encryption scheme. Figure 5-1 shows the dialog box pr esented by the Internet Explorer 6.0. Figure 5-1. The Internet Explorer displaying the encryption key length Newer web browsers do support str ong encryption by default.
Chapter 5. Usage W arning Y our web browser has to accept cookies or else login is not possible . The B050-000 has a built-in super user that has all the permissions to administrate your B050-000. See the following table for the default settings. Please note that the user “super” is not allowed to login via the serial interface of the B050-000.
Chapter 5. Usage Figure 5-3. Main page T able 5-2. Buttons from the front end Return to the main page of the B050-000. Open the B050-000 Remote Console. Exit from the B050-000 fr ont end. W arning If there is no activity f or half an hour , the B050-000 will log you out automatically .
Chapter 5. Usage The Remote Console General Description The Remote Console is the redir ected screen, keyboar d and mouse of the remote host system that the B050-000 controls. Figure 5-4. Remote Console The Remote Console window is a Java Applet that tries to establish its own TCP connection to the B050-000.
Chapter 5. Usage W ith r espect to the keyboard, the very exact r emote repr esentation might lead to some confusion as your local keyboard changes its keyboar d layout according to the remote host system.
Chapter 5. Usage Single/Double Mouse Mode Switches between the Single Mouse Mode (where only the r emote mouse pointer is visible) and the Double Mouse Mode (where r emote and local mouse pointers are visible and need to be synchonized). Single Mouse Mode is only available if using SUN JVM 1.
Chapter 5. Usage Scaling Allows you to scale down the Remote Console. Y ou can still use both mouse and keyboard, however the scaling algorithm will not pr eserve all display details.
Chapter 5. Usage Use this option if the fast sync does not work or the mouse settings have been changed on the host system. W arning This method takes more time than the f ast one and requires a correctly adjusted picture. T o setup the picture you ma y use either the auto adjustment function or the manual correction in the Video Settings panel .
Chapter 5. Usage V ideo Settings thr ough the remote console Figure 5-10. V ideo Settings Panel Brightness Controls the brightness of the pictur e. Contrast Controls the contrast of the pictur e. Clock Defines the horizontal frequency for a video line and depends on the video mode.
