System Introduction
Thank you for choosing UltraLink 2 DVI (Part # UL2-DVI) from Rose Electronics for your network access
solutions. This intelligent and innovative product is the result of Rose Electronics commitment to providing
state of the art switching solutions for today’s demanding workplace. The UL2-DVI, when installed and
connected to your network, allows you full access and control of the connected computer from the built-in
viewer client or any web browser from almost anywhere. This small, flexible, and powerful product uses Real
VNC client software that is designed for very secure, encrypted, and password protected exchange of
information between the server and the remote viewer.
The UL2-DVI sets a new standard for an easy and extremely secure way to remotely manage server room
environments, remote standalone applications such as digital signage, and many other remote applications.
Connect the UL2-DVI to a DVI/USB KVM switch like the Vista DVI Plus, and you now have access and control
to as many computers as your KVM switching system can support.
The UL2-DVI is different in the way it manages remote access to your systems. All of the systems that will be
remotely connected remain completely unchanged and can run their usual operating system normally. They
only need to be connected to the UL2-DVI unit. Being totally operating system independent, the UL2-DVI
allows users to remotely connect to Windows, Linux, UNIX, Sun, and even DOS systems without difficulty. The
UL2-DVI is ideal for remote computers running stand-alone applications like ATMs and digital signage devices.
Whatever your remote accessing needs are, the versatility of the UL2-DVI from Rose Electronics can fulfill
those needs. It can be installed at any network level, and connected to a single server, a computer running
any operating system, or to a KVM switch.
For the majority of applications, the UL2-DVI does not require an external AC power adapter. It can obtain its
power from two USB ports on the connected computer or switch. A power adapter is needed if two USB ports
which supply +5V are not available on the connected device.

UltraLink 2 DVI Manual 5
DIP Switches
The UItraLink 2 DVI has two DIP switches on its side. These are used for using the optional power adapter and
performing maintenance on the unit.
Figure 3. UltraLink 2 DVI DIP Switches
As seen in the figure above, a switch in the down position means that the function controlled by the switch is
off. Putting a switch in the up position enables its function.
DIP Switch 1
The position of DIP Switch 1 determines whether the UL2-DVI will draw power from the host computer through
the USB cables, or from the optional AC power adapter.
The default setting for DIP Switch 1 is off, causing the unit to draw power through the USB cables. The unit
cannot draw sufficient power through a single USB connection; both USB cables must be used.
If the installation requires Virtual Media support to be disabled by disconnecting the USB cable assigned for it,
it will be necessary to use the optional AC power adapter. Move DIP Switch 1 to the up (on) position and
connect the power adapter to the unit and then the AC mains.
DIP Switch 2
When DIP Switch 2 is turned on, it puts the UL2-DVI in a special maintenance mode. In this mode, normal
operation is suspended, and the unit will be ready for either a Firmware Upgrade or a Reset to Factory
Defaults. These topics are covered in the Configuration section.

INSTALLATION
UltraLink 2 DVI Manual 6
Installation
The UL2-DVI can be connected directly to a host computer, or to a DVI/USB KVM switch like the Vista DVI
Plus 4-port model (Part # KVM-4TDDL/A1). The UL2-DVI is NOT compatible with the Vista DVI Plus 8-port
model (KVM-8TDDL/A1).
This section describes how to connect the UltraLink 2 DVI to the host computer or KVM switch, and how to
change its network settings to make it visible on the network.
Making the Connections to the UltraLink 2 DVI
The first step is connecting the UL2-DVI to the host computer or KVM switch. Some of the connections are
required, and others are optional. Some depend on the position of DIP Switch 1.
While the connections can generally be made in any order, it is recommended that power be applied as a final
step. Applying power is described in the section “Connections based on DIP Switch 1” below.
Required Connections
Three connections from the UL2-DVI to the host computer or KVM switch are required: keyboard/mouse,
video, and LAN/Internet. These are as follows.
Figure 4. Keyboard/Mouse and DVI connections
For Keyboard and Mouse Input to Computer or Switch from the UL2-x`DVI
■Connecting to a host computer:Use one of the supplied USB cables to connect the USB Type B connector
labeled KM on the unit to a USB Type A port on the host computer.
■Connecting to a KVM switch: Use one of the supplied USB cables to connect the USB Type B connector
labeled KM on the unit to a USB Type A port on the User Console of the switch. These are often marked
with an image of a keyboard and mouse. Either one may be used.
For Video Input to the UL2-DVI
■Connecting to a host computer: Use the supplied DVI cable to connect the DVI-D Single-Link connector
labeled with a monitor logo to the DVI-D connector on the host computer.
■Connecting to a host computer: Use the supplied DVI cable to connect the DVI-D Single-Link connector
labeled with a monitor logo to the DVI connector on the User Console of the switch.

UltraLink 2 DVI Manual 7
Figure 5. Network connection
For Ethernet Connection to the UL2-DVI
■Connect the port labelled Link on unit to the Local Area Network or internet using a CATx cable.
Optional Connections
The UL2-DVI has two optional connections: to input audio from the host computer or KVM Switch, and to
provide a means to serially control a remote power switch. These connections are shown below.
Figure 6. Optional Serial and Audio connections
For Audio Input to the UL2-DVI
■Connecting to a host computer: Use the supplied 3.5 mm stereo jack cable to connect the audio jack
labeled In Audio to the audio output connector on the host computer.
■Connecting to a KVM switch: Use the supplied 3.5 mm stereo jack cable to connect the audio jack labeled
In Audio to the audio output connector on the User Console of the switch.
Note: Audio support through the UL2-DVI is only provided by the RealVNC Viewer that is included in the unit.
Later Viewers downloaded from the RealVNC website do not provide audio support.
For Serial Connection to a Remote Power Switch
■To control a remote power switch from the unit, connect the supplied serial power control cable between
the RS232 connector labeled Serial and the RJ-45 serial connector on the remote power switch.
Connections based on DIP Switch 1
The UL2-DVI can draw power from either two USB connections to the host computer or KVM Switch, or from
the optional AC power adapter. The position of DIP Switch 1 determines the source of its power.

UltraLink 2 DVI Manual 8
When DIP Switch 1 is OFF (default position), the unit draws power from the host computer or switch through
the USB connections. Both USB connections are necessary for the unit to draw sufficient power. The second
USB connection is also required if Virtual Media is to be enabled on the UL2-DVI.
Figure 7. UL2-DVI draws power from 2 USB connections
For Power Over USB and Virtual Media Support For UL2-DVI
Connecting to a host computer: Use the second supplied USB cable to connect the USB Type B connector
labeled VM on the unit to a USB Type A port on the host computer.
Connecting to a KVM switch: Use the second supplied USB cable to connect the USB Type B connector
labeled VM on the unit to a USB Type A port on the switch, sometimes labeled USB 1 or USB 2. Either one
may be used.
If DIP Switch 1 is placed in the ON position, power is drawn from the optional AC power adapter. This
approach is used if the Virtual Media option is to be disabled on the unit.
Figure 8. UL2-DVI draws power from Ac power adapter
For Power from AC Adapter
Connect the optional power adapter to the 3.5 mm barrel jack labeled Power, and connect the adapter to
the AC mains.
Note:The unit will always draw power from the source indicated by DIP Switch 1. If DIP Switch 1 is off and
both USB ports are not connected to a host computer, the unit will not have sufficient power even if the
optional power adapter is connected. The reverse is true when DIP Switch 1 is in the ON position.

UltraLink 2 DVI Manual 9
Note: In this manual, the term “host computer” refers to either a computer connected directly to the UL2-DVI,
or to the currently active computer from a bank of computers on a KVM switch, unless otherwise specifically
noted.
Initial Configuration
Once the UL2-DVI has been connected to the host computer and the unit has been powered up, it is
necessary to make it discoverable on the network. To do this, the network settings have to be changed so that
it is visible on the user’s LAN or on the internet. The factory network settings are as follows:
■IP address: 192.168.1.42
■Subnet mask: 255.255.255.0
■Gateway: <undefined>
If these settings do not match the values on the desired network, it will be necessary to change these values
so that the UltraLink 2 DVI can be found on the network. Changing these settings requires a direct IP
connection between a computer and the unit. Disconnect the UltraLink 2 DVI from the LAN, and use a
crossover Ethernet cable to connect it to a computer that will be used to change the network settings. This is
shown in the figure below.
Figure 9. Connections for initial IP configuration
Follow the steps given below to change the network settings. Note that this procedure assumes the computer
used to make these changes is running Microsoft Windows XP. For other operating systems, please refer to
the operating system’s notes for the steps to change IP address.
1. On the computer used to configure the unit, open Control Panel, Network Connections. Right click
Local Area Connection and select Properties. Select Internet Protocol and click Properties. Click Use
the following IP address. Set the address to 192.168.1.40, and the Subnet mask to 255.255.255.0.
Select OK.
2. Start a web browser and enter http://192.168.1.42 (UL2-DVI default IP address) as the URL.
3. The UL2-DVI will answer with the following display in the browser.

There are three selections available.
1. Connect using built-in Java VNC Viewer: This option launches a temporary Java VNC applet
2. Download Windows VNC Viewer from unit: This option downloads the executable file
“VNC_VIEWER.EXE” from the UL2-DVI. This file can be saved to the computer, or run to connect to
the UL2-DVI.
3. Download latest VNC Viewers from realvnc.com: Selecting this option will connect to the RealVNC web
site, so that the latest VNC Viewer downloaded can be downloaded.
Note: As noted earlier, the newer VNC Viewers from the RealVNC website do not have audio support. If
transmission of audio is also desired, choose option 2 and use the VNC Viewer downloaded from the unit.
Select option 1 (Connect using built-in Java VNC Viewer) or option 2 (Download Windows VNC Viewer from
unit) to connect to the computer. A connection screen will be displayed requesting the IP address of the UL2-
DVI to connect to. If the address is not already filled in, enter the IP address of the unit here. In the case of
initial configuration of a unit, enter the default IP address of 192.168.1.42.

Figure 13. Accessing UL2-DVI Configuration
In the configuration menu, click the “Network Configuration” button. It will display the Network Configuration
menu. The UltraLink 2 DVI is capable of supporting both IPv4 and IPv6 network addresses, and both types can
be set up from the Network Configuration menu. More information on this can be seen in the section on
Network Configuration later in the manual. The example below demonstrates how to change the unit’s network
address to an IPv4 address.
Figure 14. Setting Initial IPv4 network address
Click on the

UltraLink 2 DVI Manual 12
Change the IP Address, Network Mask, and Gateway to match that of the network the unit will be connected
to. The VNC port (5900) and HTTP Port (80) should only be changed if they conflict with existing network
settings. To use DHCP, check the “Use DHCP” field. When complete, “Save” the new IP information.
Note: When the unit has been configured and connected to the network, if the “Use DHCP” option was
selected, the IP address will change to whatever the DHCP server assigns it. To determine the new network
address, return to the Network Configuration screen, and the allocated network address will be displayed.
When network configuration of the UL2-DVI has been completed, change the IP information on the computer
used to connect to the unit back to the original values.

UltraLink 2 DVI Manual 13
UltraLink 2 DVI Operation
Operation of the UL2-DVI involves connecting to the unit through a Viewer and working on the host computer
from a remote location. Up to four remote users can simultaneously access and work with the host computer
as if they were in front of the host computer itself.
In order to optimize the unit’s performance, the administrator can modify its functioning in several ways. These
include modifying the Viewer Connection Options and performing operations through the Viewer window’s
toolbar. These functions are described in greater detail in the sections below.
Viewer Connection Options
With the UL2-DVI network settings configured for its network of use, connect the unit to a computer and to the
network.
Figure 15. UL2-DVI on the desired network
As mentioned in the Installation section, there are two options to connect to the unit - using the built-in Java
VNC Viewer, and using the RealVNC Viewer downloaded from the unit or from the RealVNC website.
While both viewers are almost identical, the Java Viewer is more limited than the VNC Viewer in two ways. The
first limitation of the Java Viewer is that solo 'modifier' keys are not passed by the operating system to Java
applets. That is, when "Ctrl", "Alt" or "Shift" are pressed with no other keys, a Java applet doesn't receive those
key presses. This makes it impossible for a Java Viewer to pass those keys on to a host. The other limitation is
that Java Applets cannot access a computer’s file system. This makes the Java Viewer unable to use the
Virtual Media function. As a result of these limitations, the Java Viewer is good for quick viewing of a host
computer when it is not desirable to download a VNC Viewer to the remote computer. In all other instances,
use of the VNC Viewer is recommended.
VNC Viewer Connection Options
If the VNC Viewer has not been downloaded to the remote computer, launch it from the browser by selecting
the “Download Windows VNC Viewer from unit” option. If the VNC Viewer has been downloaded to the
computer, it can be launched clicking on the VNC Viewer icon shown below.
