TECHNICAL MANUAL SAILOR SC4000 IRIDIUM
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.

IRIDIUM Installation 2 2.1 Installation Version Overview This manual covers the Transceiver Unit versions Mk2, Mk3 and Mk4. The version can easily be determined by looking at the area around the SIM card reader.

IRIDIUM 2.3 Installation Cable 2 Phone Cable connector type: RJ 11 Cable Overview Cable 1 Scanbus Cable: 9*0.
IRIDIUM Installation Cable 5 Description of connections to T-connection H4196 (optional accessory) The wire terminal blocks are connected in parallel. 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.
IRIDIUM Installation When configuring a system only including a transceiver unit and one control unit, no changes in the default termination is needed. If the system includes more than one control unit, it is needed to remove some of the default terminations. Below two examples of scanbus termination is given, when the system includes several control units.
IRIDIUM Installation 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 exceed 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 First tighten three of the screws. The wall surface should be plane.
IRIDIUM Installation d Lift the SIM card holder so that the slot points upwards. d Press hard on the spots shown in the picture below until a loud click is heard. e Insert the SIM card in the slot. Make sure that the cut-off corner of the card is placed as shown in the picture. e When putting on the finishing cover, do not use any tools – only your hands. 2.7 How to Insert the SIM Card First, open the small lid in the finishing cover protecting the SIM card reader.
IRIDIUM Installation 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.
IRIDIUM Installation 2.10 Installation of the Antenna One of the advantages of this equipment is the easy-tohandle, 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.
IRIDIUM Installation 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.
IRIDIUM Installation The table below shows the distance to other Inmarsat equipment, with and without use of filter.
IRIDIUM Installation 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. Open 60V RMS Pin 1+2 75V RMS Pin 2+3 90V RMS 2.13 External Ringer Interface The external ringer output pin in the Service/NMEA port can control an optional ringer or a lamp.
