What is a KVM switch?
How would I benefit from using a KVM switch ?
KVM is the industry term for Keyboard-Video-Mouse.
A KVM switch allows single or multiple workstations
to have local or remote access to multiple computers
located in server rooms or on the desktop regardless
of their platforms and operating systems.
KVM switches have traditionally provided cost savings
in reducing energy and equipment costs while freeing
up valuable real estate in a server room/computer room.
When KVM switches are used in conjunction with racks
and enclosures, additional floor space is gained and
cable management is made much simpler.
What cabling do I need to use with a KVM switch?
Rose KVM switches require one cable per computer
along with one cable connecting your keyboard, mouse
and monitor cables to our switches.
What do I have to install on my computers?
Nothing, Rose KVM switches are a hardware solution to
computer management. They are designed to not intrude
on the performance of the computer or the computer network.
How do I switch from one computer to another with
Rose KVM switches offer many different methods of
switching computers depending on which model best suits
your application. Some models offer buttons on
the front panel of the switch, while other models offer
a On Screen Display (OSD) with the ability to customize
names and select those names. All Rose KVM switches
allow Hot Key switching via the keyboard with a simple
What is OSD?
What is port emulation?
OSD stands for On Screen Display, This is a graphical
representation that is overlaid on top of the existing
video image and allows the ability to select the computers
connected to the KVM switch without having to push
a button on the KVM switch or using hot key switching.
The OSD also allows you configuration of the KVM switch
Port emulation is important with KVM switches. Port
emulation makes sure that the computer still thinks
the mouse is connected directly to the computer. Many
people know that if you unplug the mouse while the computer
is running, the mouse can stop working. If you have
a KVM Switch without emulation the computer may think
the mouse is unplugged.
What is Hot Key Switching?
Hot Key Switching allows you to switch between computers
without pushing the buttons on the actual switch. It
is a simple command sequence that is available in all
Rose KVM switches. Select the following sequence depending
on the model of your Rose KVM switch and remember that
all keyboard commands start with an attention sequence
of pressing and releasing the left [CTRL] key
followed by the command sequence. All command
characters are separate keystrokes and must be entered
within two seconds of each other. All numbers must be
entered using the number across the top of the keyboard.
To switch all Rose KVM switches except UltraMatrix:
nn = CPU port number on the KVM switch
To switch Rose UltraMatrix KVM Switches
nn = CPU port number on the KVM switch
I have Sun Servers in addition to PC based
Servers. Do I need two separate KVM switches?
Rose offers multi-platform KVM switches that allow
PCís, Sunís and Macís to be connected to the same KVM
switch and use only one keyboard, mouse and monitor.
Why do some computers use different cables?
Different computers have different cabling connections.
Due to this, they cannot use the same cable. Rose manufactures
cables with all types of connections. Most common
IBM PC-based computers use a PS/2 Mouse, PS/2 Keyboard,
and a HD15 VGA Monitor. Sun computers can have a Mini-Din
8 connection for their mouse and keyboard or a USB plug
can be used for both as well. They can also use HD15
VGA or a 13W3 video connection. Older Apple computers
use a Mini-Din 4 keyboard connector as opposed to the
newer models that use USB. Apple also uses DB15
or HD15 for video depending on the computer. If
you are unsure about which cable is correct for your
application, please call or email us.
How can I get access to more computers once I have
filled up my existing Rose KVM switch ?
Rose KVM switches are expandable using both Bus
and Chaining technology methods. Contact Rose
Tech Support for details on expanding your current configuration.
What is a KVM Extender?
A Rose KVM Extender allows you to send the keyboard,
monitor, and mouse signal over a long distance using
CAT5, Fiber or TCP/IP. This can be for a single computer
or can be connected to a KVM Switch to control multiple
What are the benefits of using a KVM extension product?
Rose KVM extension products allow you to place a computer
in a safe, clean, and secure environment away from dirt,
dust, clutter, and harm and access it from
a location outside the computer room. When used
in conjunction with a KVM switch, you can access remote
computers or remote workstations.
What is KVM Over IP?
KVM over IP technology allows you to access your
servers from anywhere in the world using the internet.
The UltraLink is specifically designed for KVM over
