Note: 

Your local keyboard changes its keyboard layout according to the remote host system. If 

you use a  German administration system and your host system uses a US English keyboard 

layout  for  instance,  some  special  keys  on  the  German  keyboard  will  not  work  as  expected. 

Instead, the keys will result in their US English counterpart. You can circumvent such problems 

by adjusting the keyboard of your remote system to the same mapping as your local one. 

 

The Remote Console window always tries to show the remote screen with its optimal size. That 

means  it  will  adapt  its  size  to  the  size  of  the  remote  screen  initially  and  after  the  screen 

resolution  of  the  remote  screen  has  been  changed.  However,  you  can  always  resize  the 

Remote Console window in your local window system as usual. 

 

Remote Console Control Bar

 

The upper part of the Remote Console window contains a control bar. Using its elements you 

can see the state of the Remote Console and influence the local Remote Console settings. A 

description for each control follows. 

 

 

Ctrl+Alt+Delete 

Sends the ‘Control Alt Delete’ key combination to the remote system  

 

  

Auto Adjust button 

If  the  video  display  is  poor  quality  or  distorted  in  some  way,  click  this  button  and  wait  a  few 

seconds while the U8/16-IP tries to adjust itself for the best possible video quality. 

 

 

  Sync mouse 

Activates  the  mouse  synchronization  process.  Choose  this  option  in  order  to  synchronize  the 

local AND remote mouse cursors. This is especially necessary when using accelerated mouse 

settings on the host system. In general, there is no need to change mouse settings on the host. 

 

 

 Single/Double mouse mode 

Switches between the Single Mouse Mode (where only the remote mouse pointer is visible) and 

the  Double  Mouse  Mode  (where  remote  and  local  mouse  pointers  are  visible)  Single  mouse 

mode is only available if using SUN JVM 1.3 or higher. 

 

 

Tip:

  When  in  single  mouse  mode  use  the  hotkey  combination

 

[ALT]  +  [F12]

 

to  release 

mouse control and access the menus etc.

Options 

Opens the Options menu. A short description of the each of the options follows: 

 

Monitor Only 

Toggles  the  ‘Monitor  only’  filter  on  or  off.  If  the  filter  is  switched  on,  no  remote  console 

interaction is possible but monitoring is. 

 

Exclusive Access 

If a user has the appropriate permission, he can force the Remote Consoles of all other users to 

close. No one can open the Remote Console at the same time again until this user disables the 

exclusive access, or logs off. 

 

A change in the access mode is also visible in the status line indicated by this icon.  

 

Scaling 

Allows  you  to  scale  down  the  Remote  Console.  You  can  still  use  both  mouse  and  keyboard; 

however the scaling algorithm will not preserve all display details. 

 

Mouse Handling 

The submenu for mouse handling offers two options for synchronizing the local and the remote 

mouse pointer. 

 

Fast Sync 

The fast synchronization is used to correct a temporary, but fixed skew. 

 

Intelligent Sync  

Use  this  option  if  the  fast  sync  does  not  work  or  the  mouse  settings  have 

been changed on the host system 

 

 

 

 

 

 

Local Cursor 

Offers a list of different cursor shapes to choose from for the local mouse pointer. The selected 

shape will be saved for the current user and activated the next time this user opens the Remote 

Console. The number of available shapes depends on the Java Virtual Machine; a version of 

1.2 or higher offers the full list. 

 

Video Settings 

Opens  a  panel  for  changing  the  U8/16-IP  video  settings.  The  U8/16-IP  features  two  different 

dialogs, which influence the video settings: 

 

Video Settings in the KVM section in the front end menu: 

 

The  Noise  Filter  option  defines  how  the  U8/16-IP  reacts  to  small  changes  in  the  video  input 

signal. A large filter setting needs less network traffic and leads to a faster video display, but 

small  changes  in  some  display  regions  may  not  be  recognized  immediately.  A  small  filter 

displays  all  changes  instantly  but  may  lead  to  a  constant  amount  of  network  traffic  even  if 

display content is not really changing (depending on the quality of the video input signal). All in 

all the default setting should be suitable for most situations. 

 

Note: 

This method takes more time than fast sync and requires a correctly 

adjusted picture. Use the auto adjustment function or the manual correction in 

the Video Settings panel to setup the picture.
