Overview of DZMx Functions
The Flightcell DZMx is a powerful communications system that uses the Iridium satellite and/or
4G terrestrial cellular networks to provide the following services:
Voice Calling
The DZMx provides a global phone service, enabling calls to virtually any phone in
the world, and can optionally use the Iridium Push to Talk (PTT) service
The DZMx interfaces to the aircraft intercom system, connecting crew audio to the
available phone networks
Calls are dialled from the DZMx keypad, from a computer using DZMx Connect or
from a smart device using the DZMx Connect app. A phone directory or keypad
speed dial keys are used to retrieve and call stored phone numbers
Other parties call the aircraft by dialling the aircraft’s satellite or cell phone numbers
A Bluetooth-capable phone can be connected to the audio system via the optional
DZMx Bluetooth connection to enable hands-free calling on the connected phone.
Data
Data connections are available over the Iridium satellite and cellular networks,
providing access to email and the internet (cellular networks only)
Data services can accessed from connected devices (such as mission computers,
PCs, smart devices or medical equipment) via the DZMx ethernet port or wirelessly
via the optional DZMx Wi-Fi connection.
Two-Way Messaging
SMS text messages can be sent to the DZMx over either the satellite or cellular
networks
SMS/SBD messages can also be sent to the DZMx over the Iridium network from an
Iridium web application or any email program

Page 5
Messages from the DZMx’s message library can be sent either to another satellite
phone or cell phone, or to your tracking service provider, or messages can be
composed on the DZMx Connect app.
Aircraft Tracking
The DZMx automatically sends periodic position reports to one of many tracking service
providers. Manual positions may also be triggered by the user. Additionally, the DZMx can be
configured to send position reports that mark specific events, including:
Start-up
Engine start and stop
Take-off and landing
Course change
Manual position
Emergency (mayday)
Automated Rescue Monitoring (A.R.M.)
Firefighting events
Other special purpose events.
DZMx Control Interfaces
The DZMx can be controlled from:
Its own user interface (keypad and display)
A Flightcell remote head –one or two remote heads may be installed
The DZMx Connect application, available either as a web app on a connected PC, or
an iOS or Android app
Flightcell also provides remote control APIs that can be used by the customer to
implement its own remote control system, e.g. on a mission computer or display.
These are:
The XUI protocol, which connects over RS485 or ARINC429
The Flightcell web API, for devices connected over ethernet or Wi-Fi.
These two options are not covered in this manual. Further information can be obtained
by contacting Flightcell at [e-mail].

Section 2: DZMx Equipment
The DZMx should be inspected when unpacked to check for any visible damage or missing
components.
Connectors
A connector kit is supplied free of charge with the DZMx, unless the customer requests it not be
provided.
This contains all connectors required for installation of the specific DZMx version.
The connector kit also contains an Ethernet/USB Connector Module (part number IDP_00013
with D-type connector or IDP_00012 with D38999 military-type connector). This is used for
terminating the DZMx USB and Ethernet connections.
The Ethernet/USB connector module
The DZMx ethernet and USB connections are used as follows:
Ethernet –for data connections, to configure the DZMx, and for support/troubleshooting
USB –for firmware updates (from a USB drive) and to download log files.
It is therefore essential that USB and Ethernet connections are installed on the aircraft.
Alternative ethernet and USB connectors may be used to suit the aircraft installation, but wiring must
meet the appropriate standards for these connections.

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 https://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
[e-mail] for more information.
DZMx Wiring Guide
Refer to the following wiring diagrams for the Flightcell DZMx and associated equipment
(available from https://www.flightcell.com/resources):
Civilian Wiring Diagrams for versions of the DZMx with D25 main connectors

"DZMx Antennas" on page 20
"Cellularservice
A cellular contract is required to operate the cell modem. The following should be considered when
choosing a cellular service provider:
Coverage; this varies considerably between providers
Network availability; LTE service is required for high speed data, and 3G service for voice
calling. Note, the DZMx modem does not currently support LTE in the US
Cellular bands; cellular performance is best on lower frequency bands (800-900MHz) than on
higher frequency bands (higher than 1800 MHz); it is recommended you contract on a
network which provides low frequency bands on LTE and 3G.

Page 13
AutomatedRescueMonitoring
A.R.M. (also known as Automated Flight Following, or AFF) is an optional automated flight monitoring
system. When A.R.M. is activated, your tracking service monitors position reports from the aircraft
and raises an alert when reports are overdue by a specified period, or (optionally) if the aircraft
is stationary for a specified period.
Enabling A.R.M. allows for the feature to be activated when the A.R.M. button is pressed. To
enable the A.R.M. function, on the DZMx go to MENU>Tracking>ARM Enable and select On or in
DZMx Connect go to Settings>Tracking>Automated Remote Monitoring .
Alert Mode
Alert Mode allows users to send special alert messages in specific circumstances (e.g. Under Fire).
The Alert mode setting can only be found in DZMx Connect, under the "Tracking" heading in the
settings. When enabled, it is activated via a long press on the A.R.M. key.
GeofenceSuspendMode
The Geofence suspend application allows operators to suspend tracking while the aircraft remains
within a circle of specified radius. Moving outside the geofence perimeter will cause geofence mode to
be cancelled and normal tracking to resume.
As this is an operational function activated on a trip by trip basis, details are provided in the DZMx
Operator Manual.
Note: A.R.M. can only be configured with tracking providers which support this
application. See "Tracking Providers" on page 43 for more information on A.R.M. support.
Note: A.R.M. and Alert mode cannot be enabled at the same time.

Page 14
DZMx Inputs and Outputs" on page 44.
Power Supply
The DZMx unit and other components require aircraft DC power. Operating range is 12-32VDC. It is
preferable 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
A 1 amp circuit breaker/fuse is recommended to protect a Flightcell Iridium phone cradle, if
installed
If combining two or all of the above 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 with the DZMx for terminating its USB and Ethernet
connections. Versions are available with either D-type or
D38999 connectors. Mating connectors for the wiring loom are
included with the connector module.
The Ethernet/USB connector should always be installed as it
provides the following features:
Ethernet –provides a connected device access to the DZMx data
connections and configuration using DZMx Connect.
USB –required for firmware upgrades and downloading diagnostics data.
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.
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 user
interface metalwork and the DZUS rails.
If the DZMx has a GA user interface 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.
Note: It is essential that a USB/Ethernet connector module is installed in an accessible
location.

Page 15
Installing Data Ports
The DZMx has several data ports 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 –used as a debug and for serial data connections to external Iridium devices (Iridium
modem; Flightcell Iridium cradles) and some other external devices (water tank controller on
some aircraft)
RS422/RS485 –used for serial data connections, and connection to one or more DZMx
Remote Heads
ARINC 429 –optional, used to connect to an ARINC 429 data bus.
Consideration should be given to the type and location of the Ethernet and USB data ports. Optimum
location will depend on the planned use of each data port.
ConnectorPinouts(CIV)
Refer to the Civilian wiring diagrams for the Flightcell DZMx and associated equipment (available
from the Flightcell Support website).
The standard civilian variant of the DZMx uses two D25 connectors for its main connectors. Refer to
the figure below for the layout of the DZMx backplate.

Installing a DZMx Remote Head
One or two Flightcell DZMx Remote Heads may be installed to provide other crew or mission
specialists with full remote control of the DZMx.
Each of the DZMx and remote heads must have a unique ID. The DZMx is Head A. The first remote
head is Head B and the second Head C.
Wiring the Remote Head
The remote head connects to the DMZx using the RS485 serial data connection. The remote head
also requires a 12-32VDC power supply. Two additional connections are a ground connection to the

Page 20
chassis, and a lighting input for external lighting control. Backlighting of the DZMx and remote
heads can be configured individually, see "Backlighting" on page 33 for details on adjusting the
brightness and installing the external lighting input.
Refer to the Flightcell Support website for the wiring diagram of the remote head and DZMx.
Configuring the DZMx for a remote head
First, the DZMx needs to be configured to recognise the remote heads:
Go to DZMx Connect Settings>Hardware>Head or on the DZMx press MENU>Hardware
Config>Head B Enable . Select On to enable, or Off to disable the remote head
Press ENTER to save the setting
If a second remote head is installed, repeat these steps for Head C Enable .
Configuring the Remote Heads
The remote heads now need to be allocated a head ID so that the DZMx can identify each remote
head.
Press and hold “*” on the designated remote head for 2 seconds, then release Scroll down to
Advanced>Head ID
Use the RIGHT and LEFT arrow keys to select the correct head ID (either Head B or Head
C), then press END to save.
