Installation Manual Scansat-7701 Telephone System for Maritime Communication
Introduction The SKANTI® Scansat-7701 is a single-channel Iridium® satellite system designed for the harsh sea environments with professional mariners and serious yachtsmen in mind. The SKANTI Scansat-7701 conform to all relevant international requirements. The SKANTI Scansat-7701 system consist of a compact Transceiver Unit (ITU 7701), a small Antenna Unit (IAU 7701), and two types of control units: a Control Unit Handset (ICUH 7701) and a Control Unit for Desk mounting (ICUD 7701).

IRIDIUM Installation The termination in the control unit is located on the PCB in the cradle as jumper S1 (see figure below). As default the jumper S1 is set ON. S1 ON OFF 38637 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.
IRIDIUM Installation Transceiver Unit Control Unit Terminated Terminated Connection Box 38636 2.2 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.
Installation 2.3 IRIDIUM 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 positioned as shown below: 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.
IRIDIUM 2.4 Installation 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.
IRIDIUM Installation 2.5 How to Insert the SIM Card First, open the small lid in the finishing cover protecting the SIM card reader. Then go through each of the following steps: Unlock the SIM card holder by pushing the lock with your finger nail. Lift the SIM card holder so that the slot points upwards. Insert the SIM card in the slot. Make sure that the cut-off corner of the card is placed as shown in the picture.
IRIDIUM 2.6 Installation 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: Put a screwdriver into the slot in the printed circuit board beside the SIM card reader, and press gently to unhook the plastic spear.
IRIDIUM Installation 2.7 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.
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. Please consult fig. 3, showing what area to avoid: Unobstructed view until 10° below the horizon Avoid interference e.g.
IRIDIUM Installation 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.
IRIDIUM 2.8 Installation PABX/PSTN Interface This interface handles and converts 2-wire audio and control signals from/to the PABX into audio and control signals from/to the LBT. The interface is placed on the control unit BUS, allowing the PABX to act as control unit.
