Scaling Target Video to Client Resolution
In addition to the 1:1 pixel mapping mode, which is the default when the Remote Console window
is first launched, scaling factors may be applied to the captured video in order to match various
sizes of windows on the client. This scaling may be a fixed ratio or dynamically adjustable, as
selected from the
Options > Scaling selection. The default is 100 percent, although it may result
in a viewport smaller than the virtual screen and is moved around with scroll bars. The optimal
viewing percentages are 25 and 50.
Keyboard Functions
The Spider and Spider Duo devices provide a number of useful functions for mapping or
translating between the local keyboard/keycodes and the emulated keyboard presented to the
target computer.
Soft Keyboard
With remote control of a computer, it may be that the target system and client system are in
different countries, using different languages. By using a Soft Keyboard, the local user can have
the keycodes available to send to the target that are not on the local keyboard, without worrying
about OS and application character set mappings.
Select Options > Soft Keyboard > Mapping to get a submenu listing the languages supported.
Make the desired selection, and then verify it with Show soft keyboard .
Select Options > Soft Keyboard > Show . This provides an image of the currently selected Soft
Keyboard. The Soft Keyboard sends single keystrokes as well as combinations of keys such as
Ctrl+C . For a single keystroke, click on the button with the desired character. Single keys such as
alphanumeric characters and punctuation are sent immediately. Special keys such as Ctrl , Shift ,
and F1 to F12 must be selected twice. The first click sends the signal “key is clicked.” The second
click indicates the signal “key is released” to the remote system. After the first click the button will
change its color to indicate that the key remains clicked, and that a code has not been sent. After
the second click the button will appear as usual, showing that the keycode was sent.
Click the Close button on the title bar to close the soft keyboard.
Local Keyboard
The Java Virtual Machine running the Remote Console applet on the client computer determines
its keyboard language mapping automatically from the operating environment. There may be
circumstances where it is unable to do so, such as when the keyboard mapping and OS language
do not match. The
Options > Local Keyboard selection allows manual designation of the
language/layout of the keyboard on the client system.
Hotkeys
Hotkeys provide an alternative method for sending keycode sequences defined in the section on
Remote Console Button Keys. Click
Options > Hotkeys and select the Button Key to be sent. If
