Introduction
Your Iridium equipment is a modular system that consists of a
transceiver unit, control handset unit, antenna unit and an optional
analogue PSTN telephone/PABX.
You can make and receive voice calls on the control handset and the
analogue PSTN telephone. You can connect up to four handsets
and one analogue PSTN telephone or PBX switchboard to the
system.
The system provides intercom for internal calls between any control
handsets and between the analogue telephone and a control
handset.
Via the data port on the transceiver, the unit can be used as a data
modem for dial-up data calls, Internet access, SMS and E-mail
messaging.

2.3.1 Scanbus Termination
The scanbus connecting the transceiver and the control
units, has to be terminated. Only the first and last unit on
the bus shall have the termination in ON position.
The termination in the transceiver unit is done by setting
the jumper S3, located near the scanbus terminal on the
PCB (see figure below). As default, the jumper S3 is set
ON.

2.4 Where to Place the Satellite
Transceiver Box
Mount the satellite transceiver box in a place where it is
sheltered from the wind, protected from the salty and
humid sea atmosphere. The temperature must not ex-
ceed 55° C.
To ensure that the SIM card is easily accessible, do not
place the satellite transceiver box higher than 1.5 m
above the floor.
2.5 How to Mount the Satellite
Transceiver Box
Fix the satellite transceiver box to the wall using the four
screws included in the package. The screws are posi-
tioned as shown below:
0514
First tighten three of the screws. The wall surface should
be plane. If there is a discrepancy in planeness exceeding
1 mm, level the discrepancy up by shims or washers
under the fourth screw before this is tightened.
2.6
How to Put on the Finishing Cover
When the satellite transceiver box has been mounted on
the wall, put on the finishing cover.
The small lid in the finishing cover should be shut. Press
the hooks inside the finishing cover down on the two thin
edges of the satellite transceiver box. While pressing, let
the two plastic spears inside the finishing cover into the
two square holes of the satellite transceiver box.

2.8 Optional SIM card Reader
Only direct accessible on Mk3 units produced from August
16, 2003. On older units the L-Band transceiver must be
dismounted in order to install the SIM card.
This additional SIM card reader can be used as a master
SIM card, thus allowing the crew to place individual cards
in the primary SIM card reader on the front.
The primary SIM card reader on the front has highest
priority and will thus disable the card in the optional card
reader when a card is inserted.
The optional card reader is ideal for Ship Security and
Alert installations, where a permanent SIM card is required.
Remove the lid by removing the 2 umbraco screws. After
inserting the card put the lid back on.
2.9 How to Remove the Finishing Cover
You may need to dismount the satellite transceiver box
from the wall, e.g. in connection with service.
For access to the mounting screws, the finishing cover
can be removed from the satellite transceiver box as
follows:
c
Put a screwdriver into the slot in the printed circuit
board beside the SIM card reader, and press gently
to unhook the plastic spear.
d
While pressing with the screwdriver, lift up the
same side of the finishing cover slightly to loosen it.
e Repeat this procedure on the other side of the
finishing cover.
f
You can now detach the finishing cover from the
satellite transceiver box by pulling it gently upwards.

2.10 Installation of the Antenna
One of the advantages of this equipment is the easy-to-
handle, lightweight and rugged antenna. Because the
IRIDIUM ® system is characterised by a good link margin,
the antenna is a passive quadrifillar helix type, requiring
no external power supply and consisting of only nonmoving
parts.
The following figures show the antenna and the two
different mounting accessories available:
The mounting bracket in fig. 1 can be used in two different
ways - mounted on either a rail or a pole.
Important!
To comply with FCC RF exposure regulations, the antenna
must be installed in a location providing a minimum RF
Radiation Safety Distance of 0.61m (2 feet).
Important!
It is important that the antenna cable used has a maximum loss of 3dB @ 1.6GHz between antenna and transceiver.
This antenna cable must be in one piece. Neglecting this will reduce the overall receiving/transmitting performance
at sea. If installation is not carried out in accordance with these guidelines, it will void the warranty of the product.

Precautions
In order to avoid interference or any other kind of
disturbances from other systems on board, there are a
few precautions to take note of:
Radars
According to any installation guide for radars it is of vital
importance that any other units are kept outside the
radiation beam of the radar. Please consult the illustration
down below, showing what area to avoid:
36622A
10°
e.g. from the radar
Avoid interference
10°
10°
Unobstructed view until
10° below the horizon
GPS
Tests have shown that only in case very old GPS equipment
is used, a user may expect a minor influence on the GPS
originated from the Iridium equipment. This can be avoided
by ensuring a distance of at least 1 m between the two
antennas.
Inmarsat equipment
The operating frequency bands of the iridium and Inmarsat
systems are neighbours, and it is not in any way by any
technical solution possible to completely separate these
bands. This means that interference from Inmarsat can
be expected, especially if the antennas are placed near
each other. The distance between the antennas Should
be as far as possible.
If in any way the user experiences trouble using Iridium
because of Inmarsat, a filter can be provided as an option.
This filter is placed in a suitable place between the
antenna and the transceiver. The filter is a passive type
not requiring external power. Please contact your dealer
for further information.

2.11 Analogue telephone
The PSTN interface on the transceiver unit converts the
wireless Iridium network into an ordinary telephone line.
You can connect a standard analogue PSTN telephone
directly to this interface for crew calling or as an office
phone.
With a PABX you can add more telephone lines for
multiple phones ie. office network.
The interface handles the following tasks:
• generates DC current to the phone/PABX in both idle
and active mode
• generates ringing voltage
• detects call requests from a phone/PABX
• detects DTMF tones from a phone/PABX
• outputs 12 or 16kHz billing tone for a PABX
Important: Do not connect the transceiver to a PSTN
telephone line on land.

Note: Some analogue phone line impedance may differ
from the commonly used standards. If the ringing volume
is too low, the ringing voltage can be changed to gain
higher output.
The selector switch is located under the finishing cover.
2.12 Data Interface
The Iridium transceiver unit can be used as a 2.4kbps
data modem.
Connect a PC via a serial COM port to the 9 pole data
connector using a standard serial data cable. The data
interface is a full RS232 interface with hardware
flowcontrol.
With the SMS/Email client installed on a PC you can
receive and send Iridium SMS and short emails from the
PC. The SMS/Email client is included in the transceiver
package.
To use the transceiver as a data modem a dedicated
modem software driver is needed. Please contact your
Iridium Service Provider, who can supply you with the
Iridium Data Interface software.

2.13 External Ringer Interface
The external ringer output pin in the Service/NMEA port
can control an optional ringer or a lamp. This is very useful
in noisy environments or when there is a need for ringing
indication at more locations.
The output is an open collector output and can pull down
a signal of max 32V DC and a power dissipation of max
1.25W. The output is pulsing at 0.5 Hz whenever there is
an incoming call. When the call is answered the output will
stop pulsing.

The reset button is placed next to the SIM card reader.
Pushing this button will halt the power supply and remove
power from the transceiver unit. When releasing the
button, the power will come back and thereby make a
power reset of the transceiver unit.
