LASER SAFETY
The DXZ4-AM may be ed with SFP network
modules that contain Class 1 lasers. The SFP
module emits invisible radiaon which can cause
harm if installed or serviced incorrectly. Follow
the guidelines below:
Warning: Class 1 laser product.
Warning: Invisible laser radiaon can be
emied from the aperture of the SFP port
when no bre is connected. To avoid exposure
to laser radiaon, do not stare into open
apertures.
Warning: Only trained and qualied personnel
may install, replace, or service this equipment.

This manual covers Amulet Hotkey® zero clients that use the Tera2 range of PCoIP®
processors.
It describes the principle features of these zero clients, their specicaons, operaon and
connecon to desktop peripherals. It also explains how to create a PCoIP session between a
zero client and remote PCoIP host.
For a full and detailed understanding of the PCoIP protocol, opons for connecon, security
and management, see the PCoIP Zero Client and Host Administrator Guide. The guide is
available from the Amulet Hotkey website, or directly from the Teradici website.
Amulet Hotkey zero clients are ready for use with VMware® View® version 4 and above.
This device complies with part 15 of the FCC Rules. Operaon is subject to the following

Before you start 1
1. Before you start
This manual describes the Amulet Hotkey security edion
zero clients, models DXZ4-A and DXZ4-AM. Based on PCoIP
technology from Teradici Corporaon, the DXZ4 security edion
zero clients support four heads of video in a compact unit with
dual network ports and are ideal for mission crical applicaons.
Before you connect a zero client to a PCoIP system, be aware of
the following informaon.
1.1 Terminology
The DXZ4 security edion zero client is referred to in this manual
as one of two models:
DXZ4-A: The standard security edion zero client has two RJ45
network ports;
DXZ4-AM: This model has two network ports that accept
either a ber or copper SFP module (see 1.4 and 2.2 Rear
panel features).
Note: This manual may use ‘DXZ4-A’ when referring to all
models in general. If there is a specic dierence, the manual
will reference the DXZ4-AM by name.
1.2 Extended network connecvity
The DXZ4-A and DXZ4-AM zero clients both have two network
ports, compared to the single network port of the standard DXZC
zero client. The two network ports can be ulized for trac or
network redundancy. The DXZ4-A has two RJ45 ports for copper
connecons, whereas the DXZ4-AM has two ports that accept
SFP modules for copper or bre.
1.3 Power supply
Amulet Hotkey DXZ4-A and DXZ4-AM zero clients are supplied
with a mains to DC power supply that self-senses the incoming
voltage (110-240V AC). This power supply has a locking DC
connector for use with the zero client. To release the connector,
pull the locking sleeve away from the rear of the zero client.
Important! Use only this power supply with the product.
1.4 SFP modules
Amulet Hotkey can provide a range of suitable SFP modules,
including 1Gbps and 100Mbps 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 diering specicaons, and
the distances over which they can drive a signal can vary. This
especially applies to ber SFP modules.
Important! The DXZ4-AM only supports certain models of
SFP module. If in doubt, contact Technical Support for advice.
1.5 LED status indicators
The DXZ4-A has status LEDs on the front and rear panels:
• front panel LEDs show the status of the PCoIP connecon
and the power status. See 2.3 Front panel status LEDs;
• rear panel LEDs associated with the RJ45 or SPF network
connecon indicate current network acvity. See 2.4 Rear
panel status LEDs.
1.6 Firmware revisions
PCoIP devices operate on embedded code known as rmware.
The rmware is constantly being improved and periodically
updated. To check the current version of rmware of any PCoIP
device, use the On Screen Display (OSD) or Administrave Web
Interface (AWI) management tools built into the PCoIP hosts and
zero clients. See 1.12 Zero client management tools for details.
1.6.1 Firmware updates
Amulet Hotkey periodically release new rmware to support
connuous improvement of its products. We send update no-
caon emails to nominated client representaves and include a
link to download a le containing the rmware update.
We recommend that you apply new rmware releases at the
earliest opportunity to make sure the latest improvements
and patches are acve in any deployment. The latest rmware
release and instrucons on how to update the zero client are
available in the resources area of the Amulet Hotkey website.

1.9.1 Factors aecng bandwidth
The bandwidth required depends on several factors, including:
• the number of pixels changing from frame to frame;
• the number and resoluon of screens to be encoded;
• sengs made by the user.
Exact bandwidth requirements for PCoIP are dicult to predict,
use the values in Table 1 as a guide only:
Seng Bandwidth
Idle display ~ 0
No USB or audio data ~32Kbit/s per pair of
monitors.
General oce use (that is,
wring documents) 300-500Kbit/s.
Audio 2 Mbit/s.
A signicant display change
(such as minimising or
restoring a window)
4-5Mbit/s
USB transfers < 6Mbit/s of trac
Playing full-screen video < 70Mbit/s
Table 1: 
Example1: A dual head conguraon running a word
processor, spreadsheets, and 2D illustraons/designs will
typically use between 1 and 10 Mbit/s.
Example2: A quad video head system running real me full
screen video might peak at 70 Mbit/s.
1.9.2 What happens when available bandwidth is exceeded
In all cases, PCoIP builds to a lossless image. If the required
bandwidth is not available, PCoIP dynamically adjusts the quality
to match. You can also use the zero client management tools
(see 1.12 Zero client management tools) to opmise perfor-
mance for most condions.
If bandwidth usage is a concern, we recommend tesng and
monitoring on your network. Contact Amulet Hotkey Technical
Support for assistance.
Note: You must register on the Amulet Hotkey website to
access some of the downloadable content.
1.6.2 Security measures for downloaded rmware les
Before you download a rmware update from our website:
1. Conrm that the SSL cercate for the Resources webpage is
valid and issued to the resources.amulethotkey.com domain by
clicking the padlock icon in the address bar of your browser.
Aer you download the le:
1. Conrm the le has not been modied by comparing its
SHA-256 hash with the SHA-256 hash value listed next to the
download link on the Amulet Hotkey website.
Note: Use the hash calculator of your choice to independently
calculate the SHA-256 hash for the downloaded le.
1.7 IP and MAC addresses
Before you set up a zero client, make a note of these details:
• MAC and IP address of the remote PCoIP host;
• MAC and IP address of the zero client.
You will nd the MAC address informaon wrien on the
underside of the zero client and on the conguraon record/
serial number label of the remote host. You can also use the AWI
(see 1.12.2) 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 aer approximately
two minutes and adopt the following default IP addresses:
• Zero client: 192.168.1.50
• Host card: 192.168.1.100
1.8 Remember to change the default password
You must enter a password before changing the conguraon
of the zero client. The factory pre-set password for all Amulet
Hotkey zero clients is ahkdante.
At rst login, the DXZ4-A prompts for a new password. Make
sure you set a more secure password before using the DXZ4-A.
Important! Although the DXZ4-A does not enforce a
password policy for administrator logins, we recommend that
you implement a robust and secure password policy. Where
possible, use a machine-generated password of eight or more
characters. We also recommend that you provide your users
with guidance about the secure handling of passphrases.
1.9 Consider network bandwidth requirements
PCoIP uses the Internet Protocol (IP) to transmit data
between the host and client. The data can be routed over
any IP-compable infrastructure between oces or across
connents. Performance depends on the available bandwidth
and signal latency.

1.11.2 Specify the connecon broker
You can use any of the available management tools (see secon
1.12) to specify the connecon broker:
• you must provide the IP address or DNS name of the
connecon broker;
• you must also specify the Connecon Management
Interface connecon type for the PCoIP session.

(available to download from the Teradici website).
1.12.1 PCoIP Management Console
The PCoIP Management Console (see Figure 1) has a web
interface that allows you to manage mulple devices (PCoIP zero
clients and hosts) from a central console.
From the console, you can view the status and connecon infor-
maon of all PCoIP devices. You can manage devices individually
or by group. For example, you can create device groups based on
locaon or department.
In parcular, you can assign conguraon proles to PCoIP
devices and update device rmware (for the Teradici processor).
1.10 Dual redundant network connecons
Important! Both main and auxiliary network ports (see
Figure 13: Rear panel connecons on page 20) are
connected to an internal, unmanaged network switch. The
zero client does not monitor its network links and relies on
the LAN spanning tree to prevent switching loops and to
provide redundancy.
If both network ports are connected when a connecon
between the zero client and PCoIP host is interrupted, the
recovery process is as follows:
2. The Spanning Tree network protocol brings up the redundant
path between the disconnected zero client and host.
3. The zero client aempts to resume the session. By default,
it retries for up to 30 seconds. If the remote PCoIP host is
reachable within this me, the session resumes seamlessly.
4. If the zero client cannot reach the host within the retry
period, it displays the Connect screen of the On Screen Display.
See 1.12.3 On Screen Display (OSD).
5. When the user re-authencates themselves, they are
reconnected to the previous session as it was at the me of the
failure.
Note: If you use a connecon broker to pair zero clients to
PCoIP hosts (see 1.11), you can congure the session so that
the Windows desktop is locked while disconnected.
1.11 Choose a connecon broker if required
All Amulet Hotkey zero clients can be congured to use a
third party connecon broker (also known as a connecon
management server). For example, the following connecon
broker products include PCoIP support:
• VMware View Connecon Server;
• Leostream Connecon Broker.
1.11.1 Role of the connecon broker
Connecon brokers simplify the administraon eort for
managing large complex PCoIP systems.
A connecon broker interacts with systems such as Acve
Directory to dynamically assign PCoIP hosts to zero clients based
on the identy of the user establishing a connecon from the
zero client.
Connecon brokers are also used to allocate a pool of hosts to a
group of zero clients.

DXZ4 security edition zero client
Page 12
1.12.3 On Screen Display (OSD)
The OSD appears when the zero client is powered on and
a PCoIP session is not in progress. The OSD Connect screen
displays when you press the Menu buon on the zero client
front panel.
Figure 3: 
If the zero client is in a low power state (no acvity for ve
minutes) the zero client automacally goes into a low power
state by turning o the monitors. In this case, pressing the menu
buon or a USB mouse/keyboard will wake the client back up.
The rst video head detected will show the OSD.
From the Connect screen, you can create a new PCoIP session
between the zero client and a remote PCoIP host card or a
virtual desktop.
The Opons menu in the Connect screen gives access to various
conguraon pages (these pages provide a subset of the
funconality provided by the AWI). You must enter a password
to change any zero client sengs; see 1.8.
1.13 Cooling consideraons
Amulet Hotkey zero clients are designed to operate eciently,
over a long period in a variety of applicaons. However, for
reliable operaon they must be correctly installed and properly
venlated.
Note: DXZ4-A and DXZ4-AM zero clients are passively cooled.
It is a feature of these products that they run hot. Certain
components inside the zero client use the metal case as a heat
sink, so the unit oen feels warm or possibly hot to the touch.
This is normal.
In parcular, always allow sucient space around the zero
client enclosure for cool air to enter the device and for hot air to
escape:
• do not block the air vents;
• do not install in a fully sealed enclosure.
You can also view device log les, reset devices, and control the
power state of devices.
Figure 1: PCoIP Management Console home page
Note: The PCoIP Management Console plus supporng
documentaon is available for download. For more
informaon on the PCoIP Management Console, contact
Amulet Hotkey Technical Support.
1.12.2 Administrave Web Interface (AWI)
The AWI is an embedded HTTPS web interface for PCoIP devices.
It enables you to remotely congure individual PCoIP hosts and
zero clients using a web browser.
Example: You can set device power sengs, connecon
speeds, and dene inial setup parameters. The AWI also
provides tools for updang the device rmware (for the
Teradici processor).
To access the AWI, browse to the IP address of the PCoIP host or
zero client (see 1.7).

1.13.1 Recommended enclosure size
To ensure adequate cooling in dual and quad head video appli-
caons, the enclosure must allow the following minimum gaps
around the unit:
• X=25mm, Y=25mm, Z=25mm.
Figure 4: 
Note: These recommendaons assume room temperature is
25°C and the enclosure is fully open front and back for cable
and switch access.
1.13.2 Use a spacer to stack units
If you need to stack zero clients on top of each other, we
recommend that you separate the stacked units with spacers
where S=25mm.
Figure 5: 
Without these spacers, airow is restricted and can cause higher
than usual temperatures in some units.
Important! Do not stack units without using spacers.

Figure 11: OSD Zero Client Control Panel
Note: If opon 2 is selected the host PC will either power-cycle
or power down, depending on the PC. Other conguraons
may require addional setup.
The OSD will display on either the rst monitor detected or the
primary monitor, depending on the user conguraon.
2.6.2 Operaon when connected to a soware PCoIP host
There is a dierent funcon for the Menu buon when
connecng to a soware PCoIP host (also called a PCoIP
Soware Agent).
Cauon:! When connected in a session with these soluons a
short press of the Menu buon will immediately disconnect the
session (no message is displayed).
This applies to the following host soluons:
• VMware Horizon (and Horizon Air Cloud);
• Amazon Workspaces;
• Teradici PCoIP Workstaon Access Soware;
• Teradici Cloud Access Soware (formerly called Pervasive
Compung Plaorm).
Presing the menu buon again will allow you to reconnect.

2.5 Acvate/deacvate the front panel switches
Amulet Hotkey zero clients can be installed in cable trays
beneath desks or behind control panels.
If so, there may be a risk of an accidental buon-press by
maintenance sta, or from cables pressing on the unit. This may
disconnect a PCoIP session or put the unit put into standby.
To prevent accidental operaon of the front panel switches, you
can deacvate them. They are acve by default.
2.5.1 Deacvate front panel switches
To deacvate the front panel switches:
1. Press and hold down the Funcon switch.
2. Press the Menu switch.
The switch status LED goes o to indicate that the switches
have been deacvated. See Table 3.
2.5.2 Acvate the front panel switches
To reacvate the front panel switches:
1. Press and hold down the Funcon switch.
2. Press the Menu switch.
The switch status LED illuminates green when the switches
are acve. See Table 3.

3. Set up the zero client
This secon describes how to set up your DXZ4 security edion
zero client. For port descripons, see 2. Your zero client.
3.1 STEP 1: Connect the Keyboard, Mouse and
oponal audio devices
1. Connect a keyboard and mouse either to the front panel USB
ports or to the USB ports at the rear. See Figure 12.
You can use any USB sockets on the front or rear panel for the
keyboard and mouse.
2. Connect audio devices, if used. See Figure 12.
Use the front panel audio and mic sockets to connect either:
a). a compable headset (with two jacks), or;
b). headphones and a separate microphone.
You may connect speakers to the rear panel audio output
socket. See Figure 13.
You may also connect USB audio devices to any USB socket on
the front or rear panel. See Figure 13.
