BEforE you start 1
1. Before you start
This manual is for the Amulet Hotkey DXR-H4 Quad Display KVM
Extender Host Card.
The Amulet Hotkey DXR-H4 is based on KVM-over-IP technology
using the industry standard PCoIP® protocol. It is an ideal host
soluon for remote desktop applicaons that require pixel
perfect video across mulple monitors.
Before you connect a host card to a PCoIP system, be aware of
the following informaon.
1.1 Rack mount chassis
The DXR-H4 Quad-Display KVM Extender Host Card is rack-
mounted in a specialised housing that takes the host card in the
front of the chassis and an associated personality module (see
1.2) in the rear of the chassis.
The chassis can hold a maximum of 12 DXR-H4 host cards and 12
personality modules.
The rack comes in two conguraons:
• standard: each Power Supply Unit (PSU) powers all slots (1
to 12), this gives the rack dual redundancy for the PSUs.
• split: PSU A supplies slots 1 to 6 and PSU B supplies slots
7 to 12. This is a security opon where any card can only
be fed from a single AC outlet and PSU. There is no dual
redundancy (contact Amulet Hotkey for split rack details)
1.2 Personality modules
The DXR-H4 has an accompanying personality module that ts
into the rear of the chassis. The personality module is available
in two versions:
RJ45: The standard personality module has a single RJ45
network port;
SFP: The personality module is also available with a single
network port that accepts either a ber or copper SFP module
(see 1.3 and Figure 2).
1.3 SFP modules
Amulet Hotkey can provide a range of suitable SFP modules;
including 1 Gbps and 100 Mbps ber SFP modules for single
or mul-mode ber, and copper SFP modules with RJ45
connectors. See the Amulet Hotkey SFP Modules Datasheet for
details of currently available modules.
Be aware that SFP modules have diering specicaons and that
the distances over which they can drive a signal can vary. This
especially applies to ber SFP modules.
Important!
The SFP variant only supports certain models of
SFP module. If in doubt, contact Technical Support for advice.
1.4 Cabling
You will need the following cables, available separately in short
(1 m) and long (2.8 m to 3 m) sets:
• video cable (for example Mini DisplayPort to DisplayPort);
• two stereo audio cables;
• USB cable (type A to type B).
Note: The Amulet Hotkey audio cables comprise two cables
each with a blue connector at one end and a green connector
at the other. The instrucons in this manual are specic for
this parcular cable set.
Cauon: !
The CE/EMC compliance is tested with video, USB and
audio cables with a maximum length of 3 m.
1.5 USB devices
The DXR-H4 supports a broad range of Human Interface (HID)
USB devices such as keyboards, mice and graphics tablets. There
is also planned support soon for bulk transfer USB devices such
as card readers and USB memory scks.
See the latest release notes for KVM Extender Switches on the
resources product page for details of what is supported.
Cauon: !
Isochronous devices such as web cams and USB audio
devices are not supported and will not work via remong.

Before you start
Page 10
1.8 IP and MAC addresses
Before you set up a host, make a note of these details:
• MAC and IP address of the PCoIP host;
• MAC and IP address of the zero client.
You will nd the MAC address informaon wrien on the
underside of the zero client and on the conguraon record/
serial number label of the host. You can also use the AWI (see
4.5.2) to nd the MAC addresses.
If your network uses DHCP, the host and zero client obtain
their IP addresses from the DHCP server. If no DHCP server is
available, the host and zero client me out aer approximately
three minutes and adopt the following default IP addresses:
• Zero client: 192.168.1.50;
• PCoIP Host: 192.168.1.100.
1.9 Other models
A ‘stand alone’ variant of this product, the DXT-H4 Quad Display
KVM Extender Host is also available. The DXT-H4 combines both
the card and personality module in a single enclosure and comes
with its own power supply.
1.10 Terminology
The general terms ‘KVM Extender’, ‘PCoIP host’ or ‘host’ are
used throughout this manual to describe all product variants.
1.6 Audio
1.6.1 Front and rear audio
On the DXR-H4, only the front or rear audio connecons can
be acve at one me. The rear connecons take precedence (if
there are connectors in both, or in neither).
Which port is acve depends on what port has connectors
plugged in at switch-on.
Cauon: !
Changing the connecon from front to rear or rear to
front while the unit is on will not change where the audio output
is coming from unl the unit is reset.
1.6.2 Connecng to DXZ4 zero client audio
Only connect a DXZ4 to the DXR-H4 using the phones out
socket on the DXZ4. The LINE OUT port has no funcon when
connecng to a DXR-H4.
1.7 Cooling
The unit is fan cooled. To ensure opmum venlaon and
performance of the unit, observe the following:
1. Make sure blanking plates are ed in all unused card slots.
2. Make sure there is a 1U space above and below the DXiP
rack.
For more informaon see the user
manual.
1.7.1 Blanking plates
The DXiP rack typically comes ed with blanking plates into all
unused slots at the front and back of the chassis. It is important
for EMC compliance and for cooling to make sure that these are
all ed. All slots must have either:
• a DXR-H4 host card;
• personality module;
• or blanking plate ed.

1. Press and hold the Fn buon.
2. Press the Power buon briey and release both buons at
the same me.
Note: To enable the MI permanently, you can do this with a
command from the MI command window. See Enable the
connecon to the Management Interface (on page 33).
2.5 Warning alarm
Under certain condions, such as failure of an internal power
rail on the DXR-H4 card, a warning buzzer may sound to indicate
that there is a problem, even though the card will aempt to
maintain the PCoIP link if this is possible.
The alarm can be paused by placing the card with the alarm
into ID mode (see 2.4.2). If the alarm condion persists when
the card is taken out of ID mode, the alarm will sound again. Do
not connue to use the card, invesgate the cause of the alarm.

3. Set up the DXR-H4.
This secon describes how to set up the DXR-H4.
For a descripon of the unit, see 2. Your DXR-H4 host card at a
glance.
The installaon requires that a DXiP chassis is already installed.
For informaon on how to do this, see the DXiP Quick Start
Guide, QS-DXIP-0001.
Note: This procedure outlines the install process for a single
host PC and DXR-H4 card and personality module. You can
repeat this process to install addional cards.
3.1 Turn the power o
Although the cards can be inserted whether the PSUs are
powered on or o, we recommend that where possible you
power the rack down before installing new cards.
3.2 STEP 1: Prepare the PC, workstaon or servers
Cauon: !
Switch-o the host PC before you install the DXR-H4.
1. If possible, restart the host computers to make sure any
previous updates are successfully completed.

3.2.1 STEP 2: Install the personality module
Important!
If using a split powered rack, decide rst whether
to install the rst card in slot 1 or 7, depending on which
Power Supply Unit will power the card.
1. Find the next available slot in the DXiP chassis. If no other
modules are installed, we recommend that the rst personality
module goes in slot 1.
2. With the Amulet Hotkey logo at the top, align the module
with the slot guides in the chosen slot at the rear of the DXiP
chassis. See Figure 5.
3. Put the personality module a short distance into the slot unl
the capve screws align with the holes of the DXiP chassis.
4. Push the personality module fully home.
5. Turn the retaining screws to keep the module in place.
Figure 5: Install the personality module

3.3 STEP 3: Connect the personality module to the
host computer
Cauon: !
CE/EMC compliance is tested with video, USB and
audio cables with a maximum length of 3m.
Refer to Figure 6 for the following connecons:
1. For each video cable, connect between the DisplayPort
sockets on the host PC and the Mini DisplayPort sockets on the
personality module.
2. For the USB cable, push the USB type A plug into the host PC
and the USB type B plug into the personality module.
3. Connect the audio cables:
a). If using the Amulet Hotkey audio loom, push the green
and blue connectors at one end of the audio loom into
the matching green and blue sockets on the DXR-H4 rear
panel.
b). If using the Amulet Hotkey audio loom, push the green
and blue connectors at the other end of the audio loom
into the matching green and blue sockets on the PC audio
panel.
4. Turn the host computer ON.
3.4 STEP 4: Connect the DXR-H4 to the network
Cauon: !
For the best performance, isolate the PCoIP
connecon from normal network trac.
1. For the DXR-H4 SFP variant only, push the SFP module (see
Figure 7) into the network port on the personality module (see
(3) in Figure 2).
Note This socket accepts a copper or bre SFP module. The
module can be 1 Gbit/s or 100 Mbit/s. See the SFP modules
datasheet for more details of available modules.
Figure 7: Example SFP modules
2. Connect the network cable from the network port to your
LAN/WAN.
Figure 6: Cabling for the DXR-H4 (RJ45 variant shown)

3.5 STEP 4: Install the DXR-H4 card into the rack
Cauon: !
To funcon, the DXR-H4 card must go in the same
number slot at the front of the DXiP chassis as its companion
personality module card at the rear.
1. Align carefully the DXR-H4 card with the slot guides in the
same number slot as the installed personality module. See
Figure 8.
2. Make sure the lever on the front of the card is in the ‘down’
posion, out from the card. See Figure 8.
3. Insert the card into the slot unl its connector meets the
connector of the back plane and the connector of the person-
ality module.
4. Push the lever into the ‘up’ posion, this installs the card
fully home.
5. If the DXiP rack has been powered down, turn the power to
the rack back on.
Note: If you will install more cards into the rack, wait unl all
cards are installed before you turn the power back on.
3.6 STEP 5: Change the default IP address
Cauon: !
Change the default IP address as soon as possible.
If your network uses DHCP, the DXR-H4 obtains its IP address
from the DHCP server. If no DHCP server is available, the DXR-H4
mes out aer three minutes and adopts its default IP address
of 192.168.1.100.
All DXR-H4 cards will revert to the same default IP address, this
can cause conicts as the network grows. Use the Administrave
Web Interface (AWI) to assign a dierent stac IP address from
the default.
1. Enter the default IP address of the DXR-H4 into a browser
to access the AWI. See 7.3.1 To login with the AWI for more
informaon.
2. Enter the default password ahkdante and click Log In.
3. From the Conguraon menu select the Network opon.
4. Make sure the Enable DHCP opon is unchecked.
5. Enter the new fall-back default IP address into the IP Address
elds.
6. Make sure the Enable DHCP opon is checked.
Note: If the IP address has already been changed from the
default, you can discover the IP address using the methods in
6.3 Discover the IP addresses on page 29.

3.7 STEP 6: Connect a zero client to the DXR-H4
1. Install and power up a zero client.
If you are not sure how to do this, see the relevant Amulet
Hotkey user manual or Quick Start Guide for the zero client.
When the zero client is on, you are ready to establish a new
PCoIP session.
The zero client connects to the DXR-H4 via its network
connecon.
Note: We recommend reading 4. Introducon to PCoIP rst if
you are not already familiar with the concept of PCoIP.
3.7.1 Connect to a DXR-H4 using SLP Discovery
Important!
This is one method you can use to quickly
connect your zero client to a host. For a detailed descripon
of all connecon methods, see 5. Set up a PCoIP session.
If the zero clients and KVM extender hosts are on the same
subnet, you can use the Direct to Host + SLP session connecon
type to discover available PCoIP hosts on the subnet.
You must know the IP address (or MAC address) of the KVM
extender host that you want to connect to.
1. Select the Direct to Host + SLP Host Discovery session
connecon type from the drop down list.
Figure 9:
available PCoIP hosts discovered
2. Select the host you want and click OK.
If the zero client successfully connects to the host, the front
panel PCoIP status LED illuminates green to indicate an acve
session.
3. (Oponal) You can also set the Enable Auto-Reconnect in the
advanced sengs to remember the last connected PCoIP host.
Note: You must also congure a Direct from Client session
connecon type on the host.
3.8 STEP 7: Change the default password
1. For security, we recommend that you change the default
password for your DXR-H4 at the earliest possibility.
2. See 7.3 Login to the management interfaces on page 33
for how to access the management pages where you can change
the password.
Important!
You must enter a password before changing
the conguraon of host cards and zero clients. The factory
pre-set password for all Amulet Hotkey host cards and zero
clients is ahkdante.
3.9 Setup complete
Once the zero client successfully connects to the host, check for
the following indicaons to show normal operaon:
