Note: There is considerable overlap in the bands offered by the different modem versions, so
some modems can be used in more than one geographic area, with some reduction in the
bands available.
When ordering the DZMx Plus, it is essential that the version with the correct regional modem
is ordered. Please contact
for more information on the appropriate
modem for your operational area.
Iridium Modems
The following satellite modems may be installed in the DZMx Plus:
»
One or two internal Flightcell Iridium 9523 modems.
»
An Iridium 9603 modem (used for Short Burst Data only).
External Modems and Phones
One external modem or satellite phone can be connected to the DZMx Plus via its RS232
serial port:
»
A Flightcell Iridium Modem.
»
An Iridium handset installed in a Flightcell Iridium Phone Cradle; these may be:
▪
Iridium 9555.
▪
Iridium Extreme.
The modem and the phone handsets provide the same functions (except for Iridium PTT) as
the internal Iridium modem, providing phone calling, messaging, and data. These functions
are all controlled by the DZMx Plus, so it is not necessary to use the phone keypad.
The external Iridium devices do not support Iridium PTT; this can only be provided by an
internal Iridium 9523 modem.
Activating Modems
»
Your DZMx Plus will normally be configured for the installed internal modems
prior to shipment.
»
You may need to configure the DZMx Plus for an external device such as an
Iridium modem or Iridium phone and cradle, if installed.
»
The DZMx Plus can be configured for the installed and external modem
options using DZMx Connect. Go to Settings > Hardware.
»
You will need to check the detailed configuration for each modem and
external device to ensure they are correctly configured for your operation.
SIM Cards
A SIM card is required for a DZMx Plus cellular modem.
SIM cards must be installed in the DZMx Plus for an internal Iridium 9523 if it is to be used
for phone calling and SMS messaging. A SIM card is not required for the Iridium 9523
modem if it is to be used only for Iridium PTT or for Iridium SBD.
A SIM card is not required for an Iridium 9603 (SBD only) modem.
The DZMx uses standard SIM cards, rather than the micro and nano versions.
