Section 5: 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. Preferably where there is minimal
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.
Mechanical drawings showing dimensions and mounting details are available on the
Flightcell website www.flightcell.com/resources:
»DZUS/GA Mech Assembly, for versions with DZUS front plate and D25 main
connectors

117-00008 Rev 3.0 Flightcell® DZMx Installation Manual Page 10 of 75
Effective Date: 18 February 2022
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 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
included in the supplied DZMx Connector kit 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.
An Ethernet and USB connection should always be installed as they provide 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.
The DZMx Ethernet may be wired direct to a computer, switch or router if a permanent
connection is required.
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

Installing a DZMx Remote Head
A Flightcell DZMx Remote Head is a remotely located control head for the DZMx, with
identical display and keypad. One or two Remote Heads may be installed to provide other
crew or mission specialists with full remote control of the DZMx.
Wiring the Remote Head
The Remote Head connects to the DZMx using the RS422/RS485 serial data connections.
The Remote Head also requires a 12-32VDC power supply. Two additional connections are
a ground connection to the chassis, and a lighting input for external lighting control.
Backlighting of the DZMx and Remote Heads can be configured individually, see page 32 for
details on adjusting the brightness and the installing the external lighting input.
A wiring diagram of the Remote Head is included in the wiring diagrams for the DZMx.
Configuring the DZMx for a Remote Head
Configure the DZMx to recognise the Remote Heads:
»On the DZMx control head, go to MENU > Hardware Config > Head B Enable .
»In DZMx Connect, go to Settings > Hardware > Head .
If a second Remote Head is installed, repeat these steps for Head C .
Configuring the Remote Heads
A head ID must be allocated to each Remote Head so that the DZMx can identify it. To
allocate an ID:
»Press and hold the BACK key 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.

117-00008 Rev 3.0 Flightcell® DZMx Installation Manual Page 17 of 75
Effective Date: 18 February 2022
DZMx Antennas
Flightcell supplies a range of antennas, the choice of which will depend on DZMx modem
configuration:
»Single Iridium modem: Use a Flightcell dual Iridium/GPS antenna, ANP_00043
»Dual Iridium modems: Use a Flightcell Iridium/GPS antenna, P/N ANP_00043, and a
single Iridium antenna, ANP_00045.
»Single cellular modem: Use a Flightcell cellular antenna, P/N ANP_00033.
»Dual cellular modems: Use a Flightcell dual cellular antenna, P/N ANP_00031 or two
cellular antennas, P/N ANP_00033..
Installation of Iridium and GPS Antennas
Installation drawings for the DZMx antennas are available on the Flightcell website at
www.flightcell.com/resources.
The Flightcell Iridium/GPS antenna and Iridium antenna should be installed on the top of
the aircraft where they 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

Section 6: Configuration
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. If a menu item mentioned in this manual cannot be found ensure that
the Installer Menu has been activated.
Configuring the DZMx
The DZMx can be configured using the DZMx keypad and display or using DZMx Connect. Most
settings are available on both interfaces.
It is recommended that DZMx Connect is used to configure and to change settings as it is faster
and provides a more intuitive interface than the DZMx keypad.
However, it is useful to use the DZMx keypad when real-time feedback on the configuration is
preferred:
»Adjusting audio settings.
»Configuring the general purpose inputs.
Configuration using the DZMx Keypad
Most keys on the DZMx keypad have more than one function. The following table outlines how
the DZMx keys are referenced throughout the manual.

Configuring using DZMx Connect
The DZMx Connect application can be used to configure the DZMx, change settings and edit the
DZMx phonebook and message library, as well as to access a number of other DZMx 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.
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 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 selecting MENU > Diagnostics Menu > About DZMx.
Wireless Laptop Connection
»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, go to MENU > Hardware Config > Wireless and Networks >
WiFi Enable .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.
»To connect via Wi-Fi,
