Setting up your modem
5.1
Connecting to the Iridium network
The Flightcell Iridium modem operates on the Iridium satellite network. To enable connectivity an
Iridium SIM card provisioned for the desired services is required. Please contact your preferred Iridium
service provider for details.
5.2
Configuring your DZMx to work with the modem
Your DZMx will need to be configured to use the Flightcell Iridium Modem. Instructions for configuring a
DZMx to work with the modem can be found in the o
perators’ manuals for
DZMx products. These
manuals are provided on a USB memory device supplied with your DZMx, or available from the Flightcell
support page at

.
5.3
Using the Modem Standalone
If the modem is to be used in standalone mode it will need to be connected to a PC (or embedded
device) which can control the internal Iridium transceiver directly. The Iridium modem uses the Iridium
9523 transceiver, contact Flightcell for details of the Iridium 9523 AT interface.
5.4
Configuring Data Interface
The Flightcell Iridium modem can be set to use either an RS-232 or RS-485 data interface. This selection
can be made using the switch which is accessible under the SIM card holder. The switch is sampled on
start-up and should be in the left position for RS-232 and the right position for RS-485.
