3Installing your Flightcell Iridium Extreme Cradle
3.1 Mounting the phone cradle in your aircraft or vehicle
Dimensions and mounting points are provided in drawing DRW_CR5_010_9575CradleMechanicalAssembly_1.0,
included on the USB drive supplied with your cradle or available from the support pages the Flightcell
website. ( www.flightcell.com/support.aspx )
Use 4 x M5 bolts at the four mounting points on the back of the cradle. These bolts are fastened into the back
of the cradle through a bulkhead or other similar mounting point.
The length of the bolts should be the thickness of the mounting surface plus a maximum of10mm.
3.2 Wiring the cradle
The following guidelines should be followed when constructing wiring looms:
Power cables should be 22AWG stranded. For example, M22759/34-22-9
Other cables may be 22 or 24AWG stranded, screened where indicated. For example, M27500/-
24SB2T14
Screened pairs should be used for:
MIC +/-
SPK +/-
RS232 Tx/Rx
The other flow control lines RTS, CTS, DSR, DTR, RI, DCD can utilise either screened or unscreened
cables in any groupings. Where screened cable is used, we recommend that it be grounded at one end
only to minimize ground loops
Where the GPO signal is used we recommend using a single screened cable, with GPO GND connected
to the screen and GPO connected to the core.
3.3 The main connector
The D25 main connector contains all required I/O connections to charge the satellite phone and access the
serial port and audio connection.
