Section 4: Installation
Mounting theDZMx
The DZMx should be mounted where the flight crew or radio operator have a clear view of the display and can
easily use the keypad.
The DZMx LCD is designed for optimum readability when viewed at angles between 60° above the display to
20° below. Avoid mounting the unit where the display will be viewed at an oblique angle, as it may not be
clearly readable. It is preferable to mount the DZMx to minimise sunlight shining on the display. The ideal location
is in the panel where it is readily viewed by, and accessible to the pilot or pilots.
If the DZMx is installed in the pedestal, for ease of use, it is preferable to install it as near to the front of the
pedestal as possible.
Refer to the following mechanical drawings (latest versions are available from the Flightcell website at
www.flightcell.com/resources) for dimensions and mounting details of for the DZMx:
» DZUS/GA Mech Assembly , for versions with DZUS front plate and D25 main connectors
» GA/GA Mech Assembly , for versions with GA front plate and D25 main connectors
» DZUS/Mil Mech Assembly , for military versions with DZUS front plate and D38999 main connectors.
CAD solid model files are also available on request from Flightcell International. Contact [email protected] for
more information.
DZMx Wiring Guide
Refer to the following wiring diagrams for the Flightcell DZMx and associated equipment (available from
www.flightcell.com/resources:
»Civilian Wiring Diagrams for versions of the DZMx with D25 main connectors
»Military Wiring Diagrams for versions of the DZMx with D38999 main connectors.
Necessary Installations
The following are essential parts of the DZMx installation:
»"Power Supply," below
»"Ethernet/USB Connector Module" below
»"Audio Configuration", see page 20
»"DZMx Antennas", see page 16
»"SIM Cards", see page 24.
Optional Installations
The following are optional parts of the installation.
»"DZMx Remote Head", see page 15
»"Backlighting control ", see page 25
»"DZMx Inputs/Outputs", see page 35
Power Supply
The DZMx unit and other components require aircraft DC power. Operating range is 12-32VDC. It is
recommended that the DZMx be connected to the emergency (primary) power bus on the aircraft. This is to
ensure successful operation of tracking (including engine start/stop data) and emergency calls.
When operating on a nominal 28V supply, circuit breakers or fuses of the following rating should be used
between DZMx system components and the power supply:
»A 2 amp circuit breaker/fuse is recommended to protect the DZMx system
»A 1 amp circuit breaker/fuse is recommended to protect an external modem (Iridium or cellular) module, if
installed

| Flightcell® DZMx Installation Manual Page 10 of 48 |
MAN_DZ4_001 Rev 25.0 Effective Date: 01 Jun 2020
»A 1 amp circuit breaker/fuse is recommended to protect a Flightcell Iridium phone cradle, if installed
If combining two or more circuits on a single circuit breaker, a 3A circuit breaker/fuse is recommended.
Ethernet/USB Connector Module
A Flightcell USB/Ethernet connector module (pictured) is supplied in
the DZMx connector kit with the DZMx for terminating its USB and
Ethernet connections.
Versions are available with either a D-type connector (part number
IDP_00013) or D38999 connector (part number IDP_00012) . Mating
connectors for the wiring loom are included with the connector module.
The Ethernet/USB connector module should always be installed as it
provides the following functions:
Ethernet –provides a connected device access to the DZMx data
connections and to DZMx Connect.
USB –required for firmware upgrades and downloading diagnostics.
The cable run to the USB connector should be limited to 5m of proper USB Cable to ensure compliance
with the USB 2.0 cable delay specification.
An alternative USB or Ethernet socket may be used if preferred, so long as the wiring guidelines above are
followed.
Fabricating Wiring Harnesses
All wiring should be carried out with aviation specification fireproof cable.
Screened cable should be used where indicated in the wiring diagrams. Where cable screen connections are
not explicitly shown, they should be left unterminated.
The following minimum wiring specification is recommended:
»Power supply - 22 AWG stranded (0.325mm2)
»Other cabling - 24 AWG stranded (0.205mm2).
It is recommended that enough slack be left in the main cable to enable the DZMx to be partially removed
from the aircraft panel for service or to exchange the Iridium and/or cellular SIM card.
Grounding and Shielding Terminations
The DZMx provides a chassis ground connection on the primary connector. This can be connected to a local
aircraft chassis ground point if required. If the DZMx is mounted in a DZUS rack, the housing is grounded to
the DZUS rails via the DZUS connectors and contact between the front panel metalwork and the DZUS rails.
If the DZMx has a GA front panel it is recommended to bond the DZMx to aircraft chassis ground via either the
hardpoint on the rear of the DZMx or the chassis ground pin on the primary connector.
Installing Data Ports
The DZMx has several data connections wired off the main or secondary connector:
»Ethernet –used for connecting a PC or other Ethernet-capable device
»USB –used for firmware upgrades and connecting USB-only devices
»RS232 –available for serial data connections to legacy devices and as a debug port
»RS422/RS485 –used for serial data connections, and connection to one or more DZMx Remote Heads.
Two additional data connections are available as options:
»ARINC429 –used to send and receive over the aircraft ARINC429 data bus.
»Second Ethernet –used to provide a second ethernet connection.
Note: It is essential that a USB and Ethernet connection is installed in an accessible location.

Installation of Iridium and GPS Antennas
Installation drawings for the above antennas are available at www.flightcell.com/resources.
The Flightcell Iridium/GPS antenna and Iridium antenna should be installed on the top of the aircraft where
it will have an unrestricted view of the sky, mounted as close to horizontal as possible. The following should be
considered when determining a mounting location:
»Maintain good separation from other antennas. Preferred separation is 750mm from L-band (GPS),TCAS
or transponder antennas, but a lesser separation can be applied if there is limited space on the aircraft
»On a helicopter, the antenna can be installed below the rotor blades, but avoid installing it close to the
rotor hub, as the hub and inner rotor can block the antenna’s view of the sky
»Keep coax cable lengths short to minimize attenuation of transmit and receive signals.
Installation of Cellular Antennas
A Flightcell cellular antenna should preferably be installed on the underside of the aircraft to provide best
connection to the cellular network. Typical location is below the cockpit to minimise antenna cable length. The
minimum recommended separation between the cell antenna and other antennas is 600mm.
Guidelines for Antenna Cables
Iridium antenna cables must be selected to keep signal loss within accepted levels. Total signal loss on the
Iridium connection between the DZMx or Iridium phone cradle and the antenna should not exceed 3dB at
1645MHz.
The maximum recommended length for different common antenna cable types is:
Cable Length
Cable Specification
Up to 3m
RG58C/U or RG400
Up to 6.5m
LMR200 or RG142A/U-9006 cellfoil
Up to 8m
RG213
Up to 17m
LMR400
Up to 26m
LMR600
It is recommended that the antenna cable be reduced to RG58 for the last 300mm to the DZMx to assist with
installation in the panel.
Antenna connectors on the DZMx and Flightcell antennas (as well as the supplied mating connectors) are
colour coded to reduce installation errors, as follows:

Section 5: Configuration
Configuring the DZMx
The DZMx can be configured using its user interface (keypad and display) or using the DZMx Connect
application. Most settings are available on both interfaces.
However, it is recommended that DZMx Connect is used to configure your DZMx and change its settings as it
is faster and provides a more intuitive interface than using the DZMx UI.
Use of the UI for configuration may be preferred in two cases where this provides real-time feedback on the
configuration:
»Adjusting audio settings
»Configuring the General Purpose Inputs.
Accessing Installation and Configuration Settings
Many of the DZMx configuration settings are hidden during normal operation. To access these settings, the
Installer Menu needs to be activated. The Installer Menu will remain active until the DZMx is next powered off.
Since this installation manual assumes that the Installer Menu has been activated, if a menu item indicated in
this manual cannot be found, ensure that the Installer Menu has been activated.
Configuring using DZMx Connect
DZMx Connect is a browser an application utility that is that can be used to configure the DZMx, including
changing settings and editing the DZMx phonebook and message library, as well as providing a range of other
functions. DZMx Connect is available as an iOS and Android application (available from the respective app
stores), or as a browser application on a PC.
It is highly recommended that DZMx Connect is used to alter your DZMx settings as it provides a more intuitive
interface than using the front panel. DZMx Connect also allows users to edit or import and export phonebooks,
edit the quick response messages and import/export DZMx settings files.
There are three ways to use DZMx Connect:
Hardwired Computer Connection
»Connect a computer to the DZMx Ethernet port
»Power up the DZMx and wait for it to fully initialise
Open a web browser, type in 192.168.4.1 in the address bar and press enter. The home screen of DZMx
Connect will open in the browser
If the DZMx has been allocated a fixed IP address, or the DZMx is set up as a DHCP client, then it is
necessary to enter this address (this could be, for example, 192.168.4.100). This IP address can be
determined by going to MENU>Diagnostics Menu>About DZMx.
Wireless Laptop Connection
»Power up the DZMx and wait for it to fully initialise.
»Check that WiFi is enabled. Look for a WiFi icon located at the top right-hand side of the DZMx
display. If the WiFi icon is not present it can be checked and enabled in one of three ways:
»Press and hold the MODE key until “Enabling WiFi”is displayed on the display. WiFi can also be
disabled with a subsequent press of the MODE key.
»Using the DZMx keypad, navigate to: MENU>Hardware Config>Wireless and Networks>WiFi
Enable and select Yes.
»Connect a PC or laptop to the DZMx via an Ethernet cable. Type 192.168.2.1 into a web browser
and navigate to Connectivity>WiFi and toggle the switch to ON.
»Open a web browser on the laptop and type in 192.168.2.1 then press enter; the home screen of DZMx
Connect will open within the browser.

MAN_DZ4_001 Rev 25.0 Effective Date: 01 Jun 2020
»Default SSID: DZMx WiFi
»Default password: flightcell (all lower case)
»Open the DZMx Connect app (available from Apple App Store and Google Play). The initial screen is a
discovery screen and the DZMx should be discovered automatically. The DISCOVER button is only
required if the process needs to be repeated.
If the DZMx IP address has been manually configured, it will be necessary to enter this IP address in the
browser address bar. After the first use of a custom IP address, the app will remember the address in the
Stored Devices list.
»Click on the discovered DZMx unit to open navigation and settings options.

Installers should select the Installer option. The default password is 2468.
Configuring using the DZMx User Interface
Accessing the Installer Menu
On power up, only the limited range of operational settings that may need to be adjusted by the crew will be
available on the menus, with the remainder password protected.
To access the password-protected installer menu on the DZMx:
»Go to MENU>Hardware Config>Installer Menu Enable
»Enter the password and press ENTER.
The default installer password is 2468.
Changing the Installer Password
The installer password can be changed as required:
» On the DZMx UI, go to MENU>Hardware Config>Change Installer Passwd
»In DZMx Connect, go to Settings>Preferences>Access management.
Note: It is important to record the password. If the password is forgotten, it will be necessary to reset the DZMx
to factory settings before the password protected functions can be used again.

Audio Installation and Configuration
The DZMx supports the following audio services:
»Telephony over the Iridium and cellular networks (depending on the modems installed in the DZMx)
»Iridium PTT, a Push-to-Talk service using the Iridium network to provide one-to-many PTT calling
»Telephony over a mobile phone connected to the DZMx Bluetooth service.
Connection to the Aircraft Audio System
Audio from the above services is connected into the aircraft audio system (ICS) to enable aircrew, mission crew
or passengers to use these connections.
The DZMx can be connected to the aircraft audio system or ICS in several ways, depending on the aircraft
configuration and type of operation.
It is recommended that audio from the DZMx is connected to spare radio positions on the ICS if possible.
Modem connections to the ICS are configured in DZMx Connect>Settings>Audio>Modems.
Single or Dual ICS Connections
The DZMx supports one or two connections to the audio panel/ICS, ICS1 and ICS2.
The dual ICS connections may be used to allow the DZMx to be connected to two different audio panels on the
aircraft, or to allow different audio connections to be used simultaneously.
Mirroring audio on dual ICS connections
If the DZMx has connections to two audio panels but it is desirable to have the same audio mirrored to both,
select Mirror Audio to ICS2.
Providing for modems to be connected to separate ICS connections
The two ICS connections may be used to allow the DZMx modems or connected Bluetooth device to connect to
separate ICS channels, allowing separate calls to occur on the separate respective ICS channels.
Typically, this is used where ICS1 and ICS2 are connected to different audio positions on the ICS.
Each of the modems and Bluetooth device may be allocated to either ICS1 or ICS2.
Dual Calling
The DZMx can make two calls simultaneously, either
»If the two ICS connections are wired, separate calls on ICS1 and ICS2
»If only ICS1 is wired to the audio system, two calls on the single ICS channel.
Call Priority
A modem which has been given priority will automatically mute all other calls when it makes or receives a call.
When a priority call has ended, it automatically unmutes any other call. This can be particularly useful if a call on
a modem is vital to vehicle aircraft operations. By default, call priority is off, however it can be enabled using the
"Call Priority" setting for each modem in DZMx Connect>Settings>Audio>Modems. This option can be found in
the settings under the audio section. This setting is particularly useful for simultaneous calls on a single ICS
channel.
Audio from the DZMx to the ICS
Audio from the DZMx is connected direct to the ICS input, and its levels adjusted using the DZMx audio menu
(see next page).
Audio from the ICS to the DZMx (microphone installation)
The DZMx can be installed in aircraft systems with either high impedance or low impedance microphones. Most
(but not all) civil aircraft operate high impedance (electret) microphone systems. Most (but not all) military aircraft
operate low impedance microphone systems. Refer to www.flightcell.com/resources for wiring diagrams for the
microphone connections.
Low Impedance Microphones
When installing the DZMx with an ICS that uses low impedance mics, the DZMx must be connected to a line level
Radio/Comms port. If a line-level port is not available and the DZMx is to be connected direct to the mic line, then
a tactical radio adaptor will be needed to match impedances. Options include the NAT AA34-300, Jupiter JA34-
001 or PS Engineering 200-002-0002.
