Scaling Target Video To Client Resolution; Keyboard Functions - Lantronix SecureLinx Spider User Manual

5: Remote System Control
If the timing of the video signal is slightly off, the Auto Adjustment may not capture the
frame at the right point. This will result in black bars along left, right, top, or bottom of the
Remote Console viewport, and cutting off the opposite side of the captured image. The
Offset sliders can be used to properly align the sides. Once there is correct alignment,
click Save Changes to retain those settings permanently. To discard the changes made,
click Undo Changes. To return a particular setting or all settings to the original factory
defaults, click Reset this Mode or Reset All.
Video Encoding
Various video encoding schemes have been defined to try to tailor the bandwidth usage
to what is available. In addition to the predefined schemes, compression levels, and color
depth can be manually adjusted. The default settings for each user are established in the
KVM Settings User Console Transmission Encoding web page. To change the
settings during a session, select Options Encoding Predefined,
Encoding Compression, Encoding Color Depth, and Encoding Lossy manual
adjustments. These settings will be lost when the Remote Console window is closed; for
nonvolatile changes use the KVM Settings User Console Transmission Encoding
web page.

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. 100% is the
default, which may result in a viewport smaller than the virtual screen and is moved
around with scroll bars. 25% and 50% selections are optimal for viewing several target
systems concurrently.

Keyboard Functions

The Spider provides 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, 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 indicated 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.
