1Introduction
This manual provides information on installation and configuration of the Flightcell DZMx. This version is for
the firmware releases shown on the cover page of the manual.
Additional functionality is being developed and implemented for the DZMx. Functionality that is currently
under development and will be released in the near future is marked in this manual as “Pending”.
1.1 The Flightcell DZMx –Overview
The Flightcell DZMx is a powerful communications system that uses the Iridium satellite and/or cellular
networks to provide:
Global phone calling
The DZMx provides a global Iridium satellite phone service, enabling calls from any point in the world
to virtually any phone in the world
If a cellular phone module is installed in the DZMx, calls can also be made over the cellular network,
providing significant cost savings
The DZMx is connected to the aircraft audio communication system, providing all crew with access to
these phone services
Calls are dialed from the DZMx keypad, or using the phone directory and speed dial keys to retrieve
and call stored phone numbers
Outside parties can call the aircraft by dialing the aircraft’s own satellite or cellphone numbers.
Two-way messaging
SMS text messages can be sent to the DZMx over either the satellite or cellular network, from any
SMS-capable phone (a cellphone or another satellite phone)
SMS messages can also be sent to the DZMx via Iridium from an Iridium web application or any email
program
Messages from the DZMx’s message library can be sent either to another satellite phone or cellphone,
or to your tracking service.
Data transmission
Data can be sent and received via a 3G connection on the cellular network (installed cellular module
required).
Aircraft tracking
The DZMx can send regular or manual position reports to one of a number of tracking service
providers. Event information can be attached to position reports to mark specific events, including:
Startup (master on)
Engine start and stop
Door open and closed
On/off blocks
Takeoff and landing
Course change
Emergency (mayday)
Other special purpose events.
1.1.1 DZMx design
The Flightcell DZMx has a modular design with four expansion slots enabling different configurations of
transceivers and special purpose circuit cards to be installed to suit the user’s requirements.

3.2 Mounting the DZMx
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 it 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
http://www.flightcell.com/support.aspx) for dimensions and mounting details of the DZMx:

3.3.4 Guidelines for 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.
3.3.4.1 Grounding and audio shield termination
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 DZM 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.

3.3.4.2 Noise
As there are a number of different electronic systems in the audio panel, care must be taken to avoid intrusion
of electrical noise from coupled interference, magnetic induction or ground loops.
The DZMx is designed with a fully digital audio system to minimise coupled interference, however the
interface to the audio panel is analog and you should take care when routing antenna or audio cables to avoid
close proximity to conductors carrying AC current or high frequency signals.
3.3.5 Installation of 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 –available for serial data connections to legacy devices
RS422/RS485 –used for serial data connections, and connection of a DZMx Remote Head.
Consideration should be given to the type and location of data ports installed. Optimum location will depend
on the planned use of each data port.
It is strongly recommended that USB and ethernet ports should be installed with their connectors readily
accessible, as these are used for reprogramming and configuring the DZMx, as well as for data functions.
A Flightcell ethernet and USB connector unit is sold with the DZMx (see section 3.1 for details of this
connector).
The cable run to the USB connector should be limited to 5m to ensure compliance with the USB 2.0 cable delay
specification.
3.4 Connecting to the aircraft ICS/audio panel
The DZMx is connected to the aircraft’s audio system. A second audio connection is available for use in the
following scenarios:
-To provide separate connections for pilot and co-pilot
-If there are two audio zones in the aircraft (e.g. one in the cockpit and one in the cabin).
3.4.1 Audio connections to ICS/audio panel
It is recommended that the DZMx is connected to a spare radio position on the audio panel. AUDIO FROM DZM
HI is connected direct to the audio input, and its levels adjusted using the DZMx audio menu.
3.4.2 MIC connections from ICS/audio panel to the DZMx
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.
3.4.2.1 Low impedance systems
Connect the non-biased lines from the DZMx direct to the desired radio position.
3.4.2.2 High impedance systems
There are several options for connecting the DZMx into an audio panel/ICS with high impedance
microphones. The way in which the DZMx is connected will depend on your system configuration and
operational requirements.
As the Iridium satellite phone and cell phone are both full duplex, it is preferable to use the DZMx on a hot mic
connection, rather than PTT. The DZMx will typically be installed in one of the following ways:
3.4.2.2.1 Connecting direct to a headset microphone line:
The DZMx MIC TO DZM 1 or 2 HI line is spliced to one or more headset microphone inputs on the audio panel.
As these microphone inputs have mic bias provided by the audio panel, the DZMx should have mic bias
disabled.
The way this is configured will depend on how many headsets are to have access to the DZMx:
If only the pilot is to use the DZMx, its MIC TO DZM 1 HI is connected only to the pilot’s microphone
line.

Installing the Flightcell DZMx Flightcell DZMx Installation and Configuration Manual
If both pilot and co-pilot are to use the DZMx, the MIC TO DZM 1 HI is connected to the pilot
microphone line and the MIC TO DZM 2 HI line is connected to the co-pilot microphone line.
If more than two microphones need to have access to the DZMx, an external switch is required to
select the active microphone input to either the MIC TO DZM HI 1 or 2.
3.4.2.2.2 Connecting to a cell phone port on the audio panel:
Some audio panels have a dedicated cell phone port, which provides a convenient connection option. The
DZMx MIC TO DZM 1 HI line is connected to the audio panel’s cell phone output. Please consult your audio
panel installation manual for more details.
Depending on the way this connection is configured in the audio panel, this option may require the user
switch the mic away from the radio when on a call.
3.4.2.2.3 Connecting to a spare transceiver position on the audio panel:
On aircraft with separate audio control panels at each crew position, this option enables crew to use the DZMx
and connected phones individually on demand.
On aircraft using high impedance (electret, dynamic or carbon) microphones, a bias voltage is commonly
required on MIC HI lines to the audio panel, in order to energize the user’s microphone when using the DZMx.
If mic bias is required, this must be activated on the DZMx (refer to “5.6.1” on page 31 for information on
enabling or disabling mic bias).
3.5 Connecting to the aircraft 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.
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 transceiver (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.
3.6 Antennas
Flightcell supplies a range of antennas, the choice of which will depend on DZMx transceiver configuration:
For a DZMx with single Iridium transceiver, use a Flightcell Iridium/GPS antenna, P/N ANP_00012
(white) or ANP_00014 (black)
For a DZMx with dual Iridium transceivers, use a Flightcell dual Iridium/GPS antenna, P/N
ANP_00020
If a cellular transceiver is installed, use a separate Flightcell cellular antenna, P/N ANP_00018.
3.6.1 Guidelines for installation of Iridium and GPS antennas
The Flightcell Iridium/GPS 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.
