UltraLink 2 Installation and Operations Manual
INTRODUCTION
System Introduction
Thank you for choosing UltraLink™ 2 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 UltraLink 2, 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 UltraLink 2 sets a new standard for an easy and very secure way to remotely manage
server room environments, remote standalone applications such as digital signage, and
many other remote applications. Connect the UltraLink 2 to a KVM switch and you now
have access and control to as many computers as you KVM switching system can support.
The UltraLink 2 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 UltraLink 2 unit.
Being totally operating system independent, a user can remotely connect to a Windows,
Linux, UNIX, Sun, and even a DOS system with no problem. The UltraLink 2 is ideal for
remote computers running stand alone applications like ATMs and remote digital signage
devices.
Whatever your remote accessing needs are, the versatility of the UltraLink 2 from Rose
Electronics can fulfill those needs. It can be installed at any network level, connected to a
single server, a computer running any operating system, or connected to a KVM switch.
PS/2 or USB, analogue or digital video, UltraLink 2 can handle it.
For the majority of applications, the UltraLink 2 requires no external power. It obtains its
power from the PS/2 keyboard and mouse or USB ports on the connected PC. A power
adapter is needed if you connect to a KVM switch that does not provide +5V on both the
keyboard and mouse lines.
About this manual
This manual covers the installation, configuration, operation, and applications for the
UltraLink 2 single and dual models.

Local Hot Key Sequence Use the arrow buttons to select an appropriate hot key sequence for the locally connected
keyboard. This sequence is used in combination with other key presses to access the onscreen menus and to change between hosts. The options are: Ctrl+Alt (default), Ctrl+Shift,
Alt+Shift, Alt Gr, Left + Right Alt, Left Ctrl + Alt or Right Ctrl + Alt.
Note:
DO NOT assign a Local Hot Key Sequence that is the same as other Hot
Key assignments that might be in the system UltraLink 2 is connected to. If you
have the UltraLink 2 connected to a KVM switch and assign a hot key of, for
instance, F5 and that is the same hot key used by the KVM switch, the UltraLink 2
will intercept that hot key as an instruction and not pass the key sequence to the
KVM switch.

Screensaver Timeout –
Use the arrow keys to select an appropriate period of inactivity before a screensaver is
displayed and the user is logged out. This setting applies to local users only and once the
screensaver is displayed, for security purposes the user is required to log in again. The
timeout period can be selected between 5 minutes and 1 day (24 hours), it cannot be
disabled.
Menu Bar Toggle Hot Key
Use the arrow keys to select the hot key to use to toggle the menu bar on and off. Choices
are: None, F5-F7, F9-F12
Note:
DO NOT assign a Menu Bar Toggle Hot Key Sequence that is the same
as other Hot Key assignments that might be in the system UltraLink 2 is
connected to. If you have the UltraLink 2 connected to a KVM switch and assign
a hot key of, for instance, F5 and that is the same hot key used by the KVM
switch, the UltraLink 2 will intercept that hot key as an instruction and not pass the
key sequence to the KVM switch.
Encryption
Three options are available: Always on, prefer off, prefer on. The one to choose
depends on the specific details of your installation. The use of encryption imposes a
slight performance overhead of roughly 10% but is highly secure against third party
intrusion.

Idle timeout
Determines the period of inactivity on a remote connection before the user is logged out.
The idle timeout period can be set to any time span, expressed in minutes. The
Screensaver option serves a similar purpose for local connections.
Protocol timeout
Sets the time period by which responses should have been received to outgoing data
packets. If the stated period is exceeded, then a connection is considered lost and
terminated.
Mouse Latency Allowance
This option is used during calibration to account for latency delays (caused as signals pass
through a device) introduced by some KVM switches from alternative manufacturers.
During calibration, the UltraLink-2 waits for 40ms after each mouse movement before
sampling the next. If a KVM device adds a significant delay to the flow of data, the
calibration process can be lengthened or may fail entirely. The value entered here is added
to (or subtracted from) the default 40ms sampling time.
Note: You can enter negative values (down to -40) in order to speed up the calibration
process when using fast KVM switches. Use this option with caution as it can adversely
affect the calibration process.
Mouse rate
Defines the rate at which mouse movement data are transmitted to the system. The default
option is 20ms, which equates to 50 mouse events per second. This default rate can prove
too fast when passed through certain connected KVM switches from alternative
manufacturers. In such cases, data are discarded causing the local and remote mouse
pointers to drift apart. If this effect is encountered, increase the mouse rate to around 30ms
(data are then sent at a slower rate of 33 times per second).
Background refresh rate
Use the arrow keys to alter the refresh rate for screen images via remote links. This allows
you to tailor the screen refresh to suit the network connection speeds. The options are:
Slow, Medium, Fast or Disabled. When the disabled option is selected, the remote users
will need to manually refresh the screen.
Note: When a low connection speed is detected, the background refresh is automatically
disabled, regardless of the settings of this option.
Single Mouse Mode Mouse Switch
Allows you to select the mouse button combination that can be used to exit from single
mouse mode (when active). Options are: Disabled, Middle + Right Button, or Middle +
Left Button.
Use VESA GTF
When ticked, the VESA Generalized Timing Formula will be used to help determine the
correct input video resolution and timing details. See Appendix C for a list of all supported
video modes.

Upgrade Firmware
UltraLink-2 is fully reconfigurable via flash upgrade. This will always keep your UltraLink 2
current and up to date with new enhancements and equipment. Contact Rose Electronics
for full details
To perform a flash upgrade
1. Connect to the UltraLink 2 from a remote workstation and log on as the admin user.
The firmware upgrade file (xxxxxxx.bin) must be saved on the connecting remote
workstation’s PC.
Upgrades may be performed in one or two stages depending on the update. Make
sure that switch 1 is in the off position.
2.
Access the Unit configuration page to determine the current firmware version.
Ensure that the replacement firmware file has a later version than the installed
firmware.
3.
Within the Unit configuration page, click the Advanced Unit Configuration button.
4.
Click the Upgrade Firmware button and in the subsequent dialog, note the displayed
IP address and click OK. The unit is now ready to accept the upgrade files.
5.
Open your browser and log into the unit using the IP address that was confirmed in
step 4. Once connected, use the Browse button to locate the replacement (.bin)
firmware file on your system (Stage 1 or 2). Click the Upload file button. The browser
window will confirm the current and replacement firmware versions.
6.
Click the Perform upgrade button to proceed. The upgrade progress will be shown on
screen and you will be notified when it is complete. When complete cycle power on
the unit to complete the upgrade.
Time and Date
Clicking on the “Time & Date Configuration” tab brings up the below Time & Date
Configuration menu.

Use the arrow keys to set the time (24 hour base) and date. If you wish to use NTP
(Network Time Protocol) to set the time, check the box next to Use NTP, enter the NTP
Server IP address, and then click on Set Time from NTP Server.
Network Configuration
Click on the “Network Configuration” tab brings up the below configuration menu.
Figure 12. Remote Network Configuration
The UltraLink 2 is designed to use either a static IP address or an IP address that is
assigned by your DHCP server. If you choose to use the DHCP feature, check the box
adjacent to “Use DHCP”.
NOTE: If you choose the option “Use DHCP” the IP address will change to whatever IP
address your DHCP server assigns it. Once the IP address is changed the connection to
UltraLink 2 will be lost. Also, if it is changed by the DHCP server the user must determine
the new IP address in order to connect to the computer to access.
If you choose to use a static IP address, change the IP address, IP network mask, and IP
Gateway as needed to be compatible with your network. The UNC port (5900) and HTTP
Port (80) should only be changed if they conflict with existing network settings or
equipment. .
The IP Access Control feature allows you to specify a range of IP address that will or will
not be granted access to the UltraLink 2 unit. This additional feature adds to the security of
the UltraLink 2. The default IP access control is +0.0.0.0/0.0.0.0 which grants all IP
addresses access to the UltraLink 2. Click on the “Add” tab to add an IP range to grant or
deny access.
NOTE: The IP Access Control list should have all granted access IP addresses added first
and all denied access IP address added last. This is because of the position of the entries
in the list. Once a range of addresses is denied access, it is not possible to grant access to
a particular address within the denied range down the list. Below is an example of the
correct and incorrect way to control access.
22
UltraLink 2 Installation and Operations Manual
Calculating the mask for IP access control
The IP access control function uses a standard IP address and a net mask notation to
specify both single locations and ranges of addresses. In order to use this function
correctly, you need to calculate the mask so that it accurately encompasses the required
IP address(es).
Single locations
Some of the simplest addresses to allow or deny are single locations. In this case you enter
the required IP address into the ‘Network/Address’ field and simply enter the ‘Mask’ as
255.255.255.255 (255 used throughout the mask means that every bit of the address will
be compared and so there can only be one unique address to match the one stated in the
‘Network/Address’ field).
All locations
The other easy setting to make is ALL addresses, using the mask 0.0.0.0 As standard, the
IP access control section includes the entry: +0.0.0.0/0.0.0.0 The purpose of this entry is to
include all IP addresses. It is possible to similarly exclude all addresses, however, take
great care not to do this as you instantly render all network access void. There is a
recovery procedure should this occur.
Address ranges
Although you can define ranges of addresses, due to the way that the mask operates, there
are certain restrictions on the particular ranges that can be set. For any given address you
can encompass neighboring addresses in blocks of either 2, 4, 8, 16, 32, 64, 128, etc. and
these must fall on particular boundaries. For instance, if you wanted to define the local
address range:
192.168.142.67 to 192.168.142.93
The closest single block to cover the range would be the 32 addresses from:
192.168.142.64 to 192.168.142.95.
The mask needed to accomplish this would be: 255.255.255.224
When you look at the mask in binary, the picture becomes a little clearer. The above mask
has the form: 11111111.11111111.11111111.11100000
Ignoring the initial three octets, the final six zeroes of the mask would ensure that the 32
addresses from .64 (01000000) to .95 (01011111) would all be treated in the same manner.
When defining a mask, the important rule to remember is there must be no ‘ones’ to the
right of a ‘zero’.
For instance, (ignoring the first three octets) you could not use a mask that had 11100110
because this would affect intermittent addresses within a range in an impractical manner.
The same rule applies across the octets. For example, if you have zeroes in the third octet,
then all of the fourth octet must be zeroes.
The permissible mask values (for all octets) are as follows:
Mask octet
Binary
Number of addresses encompassed
255
11111111 1 address
254
11111110 2 addresses
252
11111100 4 addresses
248
11111000 8 addresses
240
11110000 16 addresses
224
11100000 32 addresses
192
11000000 64 addresses
128
10000000 128 addresses
0
00000000 256 addresses
If the access control range that you need to define is not possible using one address and
one mask, then you could break it down into two or more entries. Each of these entries
could then use smaller ranges (of differing sizes) that, when combined with the other
entries, cover the range that you require.
For instance, to accurately encompass the range in the earlier example:
192.168.142.67 to 192.168.142.93
You would need to define the following six address and mask combinations in the IP
access control section:
UltraLink 2 Installation and Operations Manual
23
Network/address entry
Mask entry
192.168.142.67
255.255.255.255 defines 1 address (.67)
192.168.142.68
255.255.255.252 defines 4 addresses (.68 to .71)
192.168.142.72
255.255.255.248 defines 8 addresses (.72 to .79)

192.168.142.88
255.255.255.252 defines 4 addresses (.88 to .92)
192.168.142.93
255.255.255.255 defines 1 address (.93)

UltraLink 2 Installation and Operations Manual
Notes
•
The entries are not case sensitive.
•
It is not necessary to specify all keys to be released at the end because they are all
released automatically after the last code.
•
A number of KVM switches from alternative manufacturers use hot key sequences
that begin with a press/release of either the Scroll Lock or Ctrl keys. These often
require a delay between the initial key press and the channel number to allow the
switch to respond. A 500ms delay is usually sufficient.
Examples:
To end the command Press/release Ctrl + 5 + enter, enter the following: +-Ctrl+5+enter
To send the command Ctrl + Alt 4, enter following: +Ctrl+Alt+4.
To send the command Ctrl + Alt 12, enter the following: +Ctrl+ALT+–1+-2
To send the command Ctrl + 1 + enter, enter the following: +Ctrl+-1+enter
To send the command Ctrl + 15 + enter, enter the following: +Ctrl+-1+-5+enter
(the ‘+–1’ entry causes the 1 key to be pressed and released before the-2 key is
pressed).
To send the command Scroll lock 1 + Enter (with a 500ms delay), enter the
following: +–Scr*500+1+Ent

Operating procedure
From any network workstation, start a web browser and enter in the URL field, the IP
address assigned to the UltraLink 2 unit. When the unit is located on the network, it will
respond back to the web browser with the following three options:
1. Connect using built-in VNC Viewer
2. Download Windows VNC Viewer from unit
3. Download latest VNC Viewer from realvnc.com
Selecting option 1 will invoke UltraLink 2 to download a small temporary Java applet to the
connecting computer and then display the VNC Viewer Connection Details window. Verify
that the Server IP address is correct. Click on the down arrow to list the Encryption
options. Normally the default setting is used.
Click “OK” to connect to the UltraLink 2 unit.
The VNC authentication box will display requesting a Username and Password.
Enter the correct Username and Password that was set-up for the user on the configure
user menu and press enter. Upon authentication, the connected computer’s video will
display in the VNC viewer window.
NOTE:
If the username or password is entered incorrectly five consecutive times, the
remote user station’s IP address is locked out and remote access is denied.
The lockout of an IP address will show up in the log as IP address “Blacklisted”.
(See the troubleshooting section for the procedure to unlock the IP address)
Figure 19 shows the VNC Viewer toolbar and an explanation of each toolbar tab. The VNC
viewer uses a two mouse cursor technique to identify if you are working on the VNC Viewer
(Host Computer) or the remote PC’s desktop. When working within the VNC Viewer
window, the local cursor is the dot and the arrow cursor is the host computers desktop.
When you move the cursor, the arrow cursor will follow the dot cursor. When you move the
cursors off of the host computer’s desktop onto the remote computer’s desktop, a single
arrow cursor will be present for local cursor activity.

+– means press down and release the key that follows
* means wait 250ms (note: if a number immediately follows the asterisk, then the
delay will equal the number, in milliseconds - *300 = 300 ms wait)
It is automatically assumed that all keys specified will be released at the end, so there is no
need to specify

UltraLink 2 Installation and Operations Manual
Using automatic configurations
•
Every setting can be individually subjected to an automatic configuration (click the
appropriate ‘Auto’ button) and most can also be manually adjusted.
•
Use the Calibrate All button to automatically determine the optimum settings for all
items.
Note: Before using the ‘Calibrate All’ option, if possible, remove on-screen display
(OSD) elements generated by any connected KVM switches (such as a
host name label or menu). These OSD elements use different video rates
to those of the host system(s) and can affect the setting of the automatic
threshold value. UltraLink-2 uses an improved calculation procedure to
filter out the effect of these elements. However, best results are obtained
when the screen contains only host system information.
Note: To maximize performance, the threshold level is automatically increased by
50% when a slow link is detected.
Note: If the UltraLink-2 is used with one or more KVM switches, the threshold
needs to be higher than 32 due to the significant amounts of ‘noise’ that
these switches introduce. The UltraLink-2 configuration should detect such
noise and adjust the threshold accordingly.
Setting the Threshold manually
Occasionally it can be useful to manually adjust the Threshold setting, in order to achieve a
setting that best suits your particular requirements.
1
Use the ‘Calibrate All’ function to ensure that all other settings are optimized.
2
Click the Threshold left arrow button to decrement the setting by one and observe
the ‘Display Activity’ indicator.
3
Repeat step 2 until the Display Activity indicator suddenly rises to a much higher
level (i.e. 50%). This will mean that you have reached the noise boundary. At this
point, increment the Threshold value by 2 or 3 points to achieve an optimum
setting.
Phase, Position (Horizontal / Vertical), Brightness, Contrast
Use the left or right arrow keys to adjust the phase, position, brightness and contrast to
produce the desired display results.
Virtual Media
A unique feature of the UltraLink 2 is the Remote Virtual Media function. This feature
allows you to remotely send or receive files or folders from the connected computer. Single
files or collections of files and folders up to 2GB in size can be quickly transferred via the
VNC link. This can prove to be an invaluable tool when upgrading host computers from
remote positions. In order to use the Remote Virtual Media feature, a VM link must be
made between the unit and a USB port on the host computer. See Appendix D for detailed
instructions on using the Virtual Media feature.
Info

Host Tab
If UltraLink 2 is connected to a KVM switch and the Configure Host feature has been setup, the “Host” tab on the toolbar will display. It allows you to easily switch to any CPU port
on the KVM switch. Each of the 128 Host locations can be set-up with the appropriate
keyboard command sequence to switch to that port. These keyboard commands are setup from the “Configure, Host” tab. Using the Hosts tab method to switch between host
computers assures that the screen calibration details for each host are reused. The
alternative is to use KVM switch hotkey combinations.
Shared Tab
The shared feature allows you to either share the connection with up to 4 simultaneous
users or select the private mode, which inhibits other users from accessing the UltraLink 2.
In the shared mode, all connected users see and control the same computer
simultaneously. Keyboard and mouse activity is on a first come, first serve basis. This
feature allows remote users to collaborate on a common project, review information, and
other functions that involve multiple users at different remote locations.

Appendix E- VNC Viewer Options
When you are connected to the UltraLink 2 using the VNC viewer (not the java applet),
there are several options that are available to modify the way the connection is made.
Click on the “Options” tab and the below VNC Viewer Option screen will display.
When Auto select is checked,
this option will examine the
speed of your connection to the
UltraLink 2 and apply the most
suitable encoding method. This
option is suggested for the
majority of installations.
When unchecked, there are
three encoding options that can
be selected.
• ZRLE – This is a highly
compressed method that is best
suited to slow modem
connections.
• Hextile – This method offers
better performance than the
ZRLE when used over a high
speed network because there is
no need for the unit to spend
time highly compressing the
data.
• Raw – This is a primitive,
uncompressed method that is
mainly used for technical
support issues. You are
recommended not to use this
method.
Color level
This section allows you to select the most appropriate color level for the speed of the
connection to the UltraLink 2. Where the connection speed is slow or inconsistent there will
be a necessary compromise between screen response and color depth.
• Full – This mode is suitable only for fast network connections and will pass on the
maximum color depth being used by the host system.
• Medium (colors) – This mode reduces the host system output to a 256 color mode and is
more suitable for ISDN and fast modem connections.
• Low (colors) – This mode is suitable for slower modem connections and reduces the host
system output to 64 colors.
• Very low (colors) – This mode provides very rudimentary picture quality and hardly any
speed advantage over the 64 color setting. You are recommended not to use this mode.

Identities tab
This feature helps your VNC
viewer to confirm that a revisited
UltraLink 2 is
genuine and not another device
masquerading as an UltraLink 2.
The list given will retain the
identities of all visited units (that
have full security enabled).
When you first make a secure
connection to the unit, the
security information for that
UltraLink 2 unit is cached within
this Identities tab (i.e. the
“identity” is known). The next
time that you connect to the
unit, its identity is checked
against the stored version. If a
mismatch is found between the
current and the stored identities
then a warning will be issued to
you. If an existing UltraLink 2 is
fully reconfigured then it will
need to be issued with a new
identity. In this case the
previous identity, listed in this
tab, should be removed so that
a new identity can be created on
the next connection.
