This page allows you to set up the KVM server operation: video quality and optimization, KVM switch model, auto scanning function.
After you have made all modifications, click Store Settings to save your settings and then hit Apply Settings/Restart Servers to validate these new settings. Every change you have made on this page will NOT apply until you hit Apply Settings/Restart Servers!

Filter Level: Specify here the Video Filter Level for the video server. Based on the bandwidth availability, you can select one of the three modes of video filter levels:
Each of the three video filter levels is adapted to different combination of video quality and bandwidth requirements. Users can select their preference according to their actual video quality preference and network bandwidth availability. However, there’s always a trade off between video quality and response speed when under limited network bandwidth availability.
High Quality, Low Speed (Light Filter): -
This level is recommended for high bandwidth networks such as
LAN or broadband internet. It requires more bandwidth
than the other two filter levels and video refresh speed is slower (however,
only noticeable when bandwidth is very limited). This filter provides the best
image quality.
Medium Quality, Medium Speed (Medium Filter): This
level is recommended for internet connections. It requires
more bandwidth than the Low Quality High Speed, option. This is most often
the best speed / bandwidth compromise.
Low Quality, High Speed (Strong Filter): This level is recommended for very limited bandwidth conditions, such as a dial-up modem line to the Internet. With this setting, the viewer screen is updated only on big video changes. Most of time there will be no transmission at all.
Automatic Filter Adjustment: When this option is checked, can tune the video filter automatically for optimized performance according to the current bandwidth availability.
Automatic Screen Alignment: When this option is checked, tries to center the view screen automatically to eliminate the offsets sometimes seen in the viewer screen as black gaps.
Automatic Image Optimization for Speed: When this option is checked, tries to optimize the video settings (phase, light and contrast) to produce images of better quality with higher compression.
Model: If you ever use a KVM Switch behind
the for connection with multiple computers, you should then select
the model of the KVM Switch. If the KVM switch model does not appear in the
list, you can always add it or even add more KVM switch models to augment the
list, so that your computer icons (as you see on the Select Computer box) can
support the port switching hotkeys of that specific KVM Switch upon clicking.
For more information on how to add a KVM switch model to the KVM switch database,
please refer to the KVM
Switch Database page. For more information on how to name a computer
as it appears on the computer icon of the Select Computer box, please refer
to the Computers page.
Number of Computers: Specify a maximum allowable
number for total connected PCs for the KVM Switch attached behind .
You can specify a maximum of 256 computers, as you might have a configuration
of several cascadable KVM Switch units behind .
Scanning Period: The scanning period is the default scanning duration for each connected PC, if no KVM (Keyboard - Video - Mouse) event happens to interrupt the scanning. If there is a KVM event such as keyboard/mouse movement or video resolution change, the scanning will be temporarily held until it reaches the timeout of the scanning delay, and then go scanning to the next. Here you can specify the scanning period in seconds.
Scanning Delay: The scanning delay is the time that the will wait after it last perceives a KVM (Keyboard - Video - Mouse) event before it switches to the next connected PC.
Performing the NumLock Test while scanning: The NumLock test is a way to detect whether a computer is still responding to keyboard action. If you check this option, , the will send a NumLock signal to the PC while scanning. If the PC returns a response, then he NumLock LED will be lit. The NumLock test can serve as a test to see if the connected PC is still responsive to keyboard event. And also the NumLock signal will serve as a “wake up” signal if the PC is in sleep mode. If the NumLock test has failed, it most likely indicates that your computer is in trouble. Check this option if you want to use auto scanning to monitor whether each of your computers has stayed alive or not.
You can also specify which computer will be included and which computer will not be included within the auto scanning process. For more information on how to add or remove computers from the auto scanning list, please refer to the Computers page.
Also, if combined with the Alarm options, auto scanning can detect critical server problems such as No Video, Blue Screen, NumLock Test failure on first timing basis, and send either an alert email or SNMP message, or power cycling commands to a Serial Power Control device to power cycle the server in problem. For more information on how to configure the alarm features of the , please refer to the Alarms pages.
