2.3 Power requirementsDepending on your particular TT-3000 System you will need AC supply or a DC supply.

A TT-3000 Integrated Capsat System operates on either 115 VAC, 220 VAC or floatingDC in the range from 10.5-32 Volt. The total power consumption varies with theparticular system in question.

As a guide-line, please note the power consumption of the following equipment:

TT-1542B Call Alarm 0.6 WTT-3022A Capsat Transceiver incl. antenna 9.5W RX 80W TXTT-3602D SVGA Monitor 60 WTT-3606A Message Terminal, incl keyboard. 8WTT-3608A Printer 33WTT-3042B Remote Alarm 2.5W 7W PrintOption 005 Built-in GPS 2W

Table 3: Capsat System component power requirements.

2.3.1 AC mains operationAs the TT-3020B Capsat Transceiver is designed to work on floating DC ranging from10.5 - 32 Volt, an AC/DC converter is needed in case the Transceiver is subject to workin AC environments.

2.3.1.1 Integrated Capsat System

For a TT-3000 Integrated Capsat System with an IBM compatible PC we recommend theTT-3680A Power Supply.

The TT-3680A Power Supply operates on either 115 VAC or 230 VAC. (internallyselectable) and supplies 24 VDC/96 Watt as a maximum.

The TT-3680A will adjust the DC output level (10.5 - 32 Volt) according to the total load.

The TT-3680A Power Supply may be connected to the emergency batteries offeringautomatic switch-over to DC in case of a mains line drop-out.

For a TT-3000 Integrated Capsat System with a TT-3608A Message Terminal werecommend the TT-3680B Power Supply.



The TT-3680B Power Supply operates on either 115 VAC or 230 VAC. (internallyselectable) and supplies 24 VDC/200 Watt as a maximum.

The TT-3680B will adjust the DC output level (10.5 - 32 Volt) according to the total load.

The TT-3680B Power Supply may be connected to the emergency batteries offeringautomatic switch-over to DC in case of a mains line drop-out.

2.3.1.2 Power connector

The battery connector matches the Thrane & Thrane standards for battery connectors.

Regardless whether the unit is designed to work on floating DC or modified to matchyour DC requirements the pin assignment of the DC/Battery power connector looks likethis:

PinPin NameName Signal DescriptionSignal Description1 SGND Safety Ground2 SUP+ Supply Voltage, positive terminal3 SUP- Supply Voltage, negative terminal4 ON/OFF Remote ON/OFF Switch

Table 4: TT-3020B Capsat Transceiver DC Power Connector pin assignment

Pin 4 is a unique feature for the TT-3020B Capsat Transceiver.

When this pin is left floating the Transceiver is turned off, but if pin 4 is shorted to thenegative terminal of the battery or DC-supply the Transceiver will switch on. Thismakes it possible for other equipment to perform remote power control of the TT-3020B.

The remote power control can be triggered by an external relay or solid state switch.

The battery connection is floating, i.e. there is no galvanic connection from any of thebattery poles to the cabinet frame.




2.3.2 FusesIn case you experience that a fuse needs replacement, please check that the equipmenthas not been exposed to physical damage before fuse replacement takes place.

WARNINGWARNINGTo avoid hazardous electrical shock, do not perform electricaltests if there is any sign of shipping damage to any portion of

the front or rear panel or the outer cover. Read the safetysummary at the front of this manual before installing or

operating the TT-3020B Transceiver.

As a guide-line, please note the fuse location of the following equipment:

Table 5: Capsat System fuses

The TT-3680A/B Power Supply may blow an internal fuse in case you power up theentire Integrated System with all DC units turned on. It is therefore recommended topower up the DC units one by one.

2.3.3 GroundingRF-grounding of an Integrated Capsat System requires special attention.



Each unit shall have its own individual low-inductance earth connection. The use of acommon busbar for grounding is not recommended as this can lead to unwantedcommon-mode coupling effects.

The ground should be connected to the cabinets metal frame to provide a return pathfor fault currents due to equipment malfunction or external faults such as lightning faults.

Interconnecting cables must be well screened.




2.4 TT-3001 Antennas

Figure 1: Maritime antenna.

2.4.1 Antenna typesYour Integrated Capsat System has been delivered with a TT-3001B Option 001Maritime Antenna. The antenna is compatible electrically with the earlier TT-3001Aantenna with or without Option 003 (GPS signal filter).

2.4.1.1 TT-3001B Option 001 Maritime Antenna

This is an omni-directional antenna with built-in

² High Power Amplifier, HPA, TT part no. 60-102195

² Low Noise Amplifier, LNA, TT part no. 60-101805

² Combiner, TT part no. 60-102193

² Diplexer, TT part no. 69-101916

² Maritime Antenna element, TT part no. 69-102192

The antenna is very compact and is designed to operate in a corrosive environment andin extreme weather conditions without any service. It has a modular construction thatallows easy exchange of antenna elements. The antenna housing is sealed with tamper-resistant TORX screws, so that it can only be disassembled by Thrane & Thraneapproved technicians.

The antenna is fully compatible with the Inmarsat-C GMDSS specifications, and can alsoreceive GPS signals while not transmitting.



2.4.2 Mounting bracketThe omnidirectional maintenance free antenna unit must be mounted in a high locationwith direct line-of-sight to the satellites.

Illustration of the 1½" Adaptor for mouting on a pole is enclosed in the back of thismanual.

The Adaptor may be removed by loosening the three Allan screws fitting the bracket tothe antenna.

2.4.3 Antenna connector"N" type connectors are available from manufacturers like:Suhner, Radial, Omnispectra, Kings, etc.

2.4.4 Antenna cableYour Integrated Capsat System, has been delivered with a 5m coaxial cable, pre-terminated with a standard connector of "N" type.

The specifications requires that the total maximal attenuation at 1.65 GHz must be lessthan 16 dB, and the maximal total (short-circuited in one end) DC resistance must notexceed 0.8 Ohms.

In case the antenna cable is to be produced on site, the cable type should match thebelow listed guide-lines:

Range (m)Range (m) Cable type no.Cable type no. Connector type no.Connector type no.(Suhners)(Suhners)

Table 6: TT-3020B Capsat Transceiver Antenna Cable types

All antenna cables types are double shielded.

The antenna cable may run together with radar or navigator cables. Separate cableditch is not required.




If you install your system in a permanent location, we recommend that you, after theinstallation of the antenna, wrap the connector with the enclosed self-bonding tape,disabling water from penetrating the connection.

2.4.5 Mounting considerations

2.4.5.1 TT-3001B-opt. 001 Maritime Antenna

When installing the Maritime Antenna you should find a location on the vessel that is asfree from obstructions as possible. Also you should maintain a certain distance to otherantennas, especially radar installations. Normally the best place for the antenna wouldbe above radar scanning antennas. The following safe distances should be maintained:

Distance to HF antennas > 5 m

Distance to VHF antennas > 4 m

Distance to magnet compass > 3 m

The antenna is designed to provide satellite coverage even when the vessel has pitchand roll movements up to 15°. To maintain this coverage the antenna should be freefrom obstructions in the area down to 15° below the horizon. Since this may not bepossible in the fore and aft directions of the vessel, the clear area can be reduced to 5°below the horizon in the fore and aft directions and 15° below the horizon in the portand starboard directions. Any compromise in this recommendation will degradeperformance.

15°

HorizonHorizon

Zenith

15°

Obstructions should be below these lines

Capsat

Figure 2: TT-3001B Option 001 Maritime Antenna mounting.



If an obstruction such as a pole or a funnel is unavoidable, the following guidelinesapply:

The distance to the obstruction should large enough, so that the obstruction only covers3 degrees. This means that the safe distance is:

Safe distance = 20 * Diameter of obstruction

Example:

Obstruction is a 4" pole. Diameter = 0.1 m. Safe distance is 20 * 0.1 m = 2 m

Max. obstruction angle 3 degrees Capsat

Figure 3: TT-3001B Option 001 Maritime Antenna mounting near pole or funnel.




2.4.6 Safety Distance for Antenna UnitsThe safety levels for the Thrane & Thrane INMARSAT-C Antenna Units are based on theANSI standard C95.1-1982 "American National Standard Safety Levels With Respect toHuman Exposure to Radio Frequency Electromagnetic Fields, 300 kHz to 100 GHz"

This standard recommends the maximum power density at 1.6 GHz exposed to humanbeings not to exceed 5 mW/cm².

At the maximum radiated output power from the INMARSAT-C Antenna (16 dBW EIRP)this corresponds to a minimum safety distance on 30 cm.

To be sure that this distance is respected the Thrane & Thrane INMARSAT-C AntennaUnits are provided with a label declaring a minimum safety distance on 2 feet (61 cm).

In the future standards from the European Telecommunication Standard Institute (ETSI)concerning 1.5/1.6 GHz Satellite Earth Stations the recommendation will be maximum8W/m² (0.8 mW/cm²). This tighter recommendations correspond to a minimum safetydistance on 60 cm at 16 dBW, so these future European recommendations are alsocovered within the declared minimum safety distance on 2 feet (62 cm).



2.5 TT-3020B Capsat Transceiver

Figure 4: TT-3020B Capsat Transceiver

2.5.1 Mounting bracketThe TT-3020B Capsat Transceiver is supplied with an universal mounting bracket (41-100562) which allows "over" or "under" mounting to e.g. a table or ceiling.

It is recommended that the Transceiver is mounted in an open air location allowing theoperator full access to the front panel in a distress situation.

When the Transceiver is used with other Thrane & Thrane equipment such as theTT-3606A Message Terminal or the TT-3210A Radiotelex Modem, stacked mounting maybe achieved using mounting bracket 41-100742.

It is strongly recommended not to stack mount the TT-3020B Capsat Transceiver withthe TT-3680A Power Supply because of the heat generation from this unit.

2.5.2 Communication portThe TT-3020B Capsat Transceiver communicates with a controller device via thestandard EIA RS-232D ports, located on the rear panel at X4.

2.5.2.1 Baudrate and protocol settings

2.5.2.3 Interfacing to peripherals

The transceiver may be used in numerous configurations for operation with equipmentlike:



² TT-3606A Message Terminal.

² IBM Compatible PC with a TT-10202A/B Message Terminal emulating software.

² Computerized equipment.

² Handheld terminals, etc.

2.5.2.3.1 TT-3606A Message Terminal

To Interface the TT-3020B to a TT-3606A Message Terminal, simply use the 30cmcommunication cable enclosed in the delivery (part no TT-61 100921).

An extended serial communication cable should not exceed 100 meters as the TT-3606Aworks on 4800 Baud using the RS-423 standard.

2.5.2.3.2 IBM Compatible PC (Personal Computer)

Interfacing the TT-3020B to a IBM Compatible PC, simply use the communication cableenclosed in the delivery: Either 9-9 pin (part no TT-61 100823) or 9-25 pin (part noTT-61 101034).

An extended communication cable should not exceed 8 meters as the TT-10202AMessage Terminal emulating software works on 4800 Baud using the RS-232C standard.

As the PC hardware normally does not conform to the RS-423 standard the maximumlength of the connection cable is less than for the TT-3606A solution.

As the TT-3020B rely on the CTS and DTR hardware handshake signals it is veryimportant that the PC you use is IBM hardware compatible with respect to the serialcommunications interface.

2.5.2.3.3 Computerized equipment

Before connecting the TT-3020B to any computerized equipment you are recommendedto consult the computer installation manual to check the pin assignment of the serialcommunication port.

Your TT-3020B is configured as Data Communications Equipment (DCE).

Most computers are configured as Data Terminal Equipment (DTE).If this is the case for the particular computer, you will probably be able to provide thenecessary connections with a multi-wire cable, as shown in the tables below:

2.5.7.2 NMEA 0183 Transmission

When you have a built-in GPS it is possible configure the Transceiver to send out NMEA0183 navigational data so that devices connected to the Transceiver via the T-Busconnector will benefit from the GPS information.

To use NMEA output you must set:

SWITCH 1 OFF and SWITCH 3 ON

The following four strings:

VTGHeading and speed information

GLLGeographic position, latitude and longitude

GGAGlobal Positioning System fix data (includes time of position)

ZDATime and date

are sent out when the Transceiver has a built-in GPS and it is in navigation mode. Thetime in the position strings and the Time-and-date string are always the same.

The spacing between each block of data is 2 seconds and 0.5 seconds between GLL,GGA and ZDA strings when they are present.

An example is:

$GPVTG,000.,T,000.,M,00.0,N,00.0,K

$GPGLL,5544.44,N,01228.64,E,121003,A

3.3. System GenerationSystem Generation

3.1 IntroductionThe System Generation is a special mode that the TT-3020B Capsat Transceiver canenter when powered ON. This mode allows you to change the general operation of theequipment before you start using it for communications.

The TT-3020B Capsat Transceiver has an enhanced level of System Parameter security.

The Transceiver will normally access and change System Parameters that are stored inthe non-volatile memory of the EEPROM chip, without any user intervention.

In the case that some of the special System Parameters needs to be changed, you willhave to permit the Transceiver to store these in the Protected part of the EEPROM. Thispart of the EEPROM memory can only changed if you press the SetSet button on thefrontpanel of the Transceiver.

This allows you to completely control when this information should be updated.

The information stored in the protected part of the EEPROM is:

The Thrane & Thrane serial number.

The main Network Coordinating Station Table.

The Mobile Type (Landmobile or Maritime).

The X4 connector serial communications settings.

For now you should only enter your Mobile Number and your Mobile Type.

The Mobile Type of your Transciver is Maritime, and this may already have beenentered for you by the person that installed your system.

In this case you only need to enter your Mobile Number.



3.2 Terminal preparationAlteration of the TT-3020B Capsat Transceiver parameters may be accomplished bymeans of:

² TT-3606A Message Terminal.

² IBM compatible PC running DOS version 2.00 or later, with a communicationsoftware or theMessage Terminal emulating software TT-10202A/B.

² Computerized equipment.

² Handheld terminals, etc.

Please follow the below listed guide lines to set up the connected equipment in a directterminal emulating manner.

3.2.1 TT-3606A Message TerminalEnter the terminal emulation mode by selecting:

OPTIONS - CONFIGURATION - TERMINAL

3.2.2 IBM Compatible PCEnter the terminal emulation mode in the TT-10202A/B software by selecting:

OPTIONS - CONFIGURATION - TERMINAL

3.2.3 Computerized equipment/handheld terminalsYour computer/terminal should display the ASCII characters as they appear being sendfrom the TT-3020B Capsat Transceiver.

No alphabet or protocol conversion should take place.




3.3 Entering the System GenerationThe procedure is as follows:

1. Turn on your Transceiver while you press the SetSet button. You must hold down thebutton for at least 10 seconds or at least until you can hear the connected printerbeing initialized.

2. Now hit the ENTERENTER key and watch the TT-3020B System Generation menu appearon your screen. If this does not happen, repeat steps 1 and 2.

3.4 The system generation menuHaving followed the instructions in the previous section you should now see the menuon your screen:

Thrane & Thrane system generation menu: Capsat Transceiver

0 Quit

1 Init system parameters

2 EGC settings

3 Filerouting

4 Reporting service

5 NCS Table

6 Preferred ocean

7 Console settings

8 Mobile Number

Enter number >

To perform an action on the list you just type in the appropriate number. If you want tosee the menu again just type CTRL+C (Hold the CTRL key down while typing a C).

The CTRL+C combination also acts as a Cancel facility. It will always bring you back tothe menu without changing any parameters.

Note:Note:Do not hit the ESCESC key if you use the Thrane & Thrane Message HandlingProgram. If you hit the ESC key you will go back to the menu of the MessageHandling Program and an error will occur as the Transceiver will not repond tothe normal commands while in the System Generation.

If you do hit ESC, then turn off both units and proceed as in section 3.3 on page37.



3.4.1 Entering your mobile type and numberFor ease of operation and general information when you operate your Capsat system,you should consider to enter the mobile number.

Just type in the Inmarsat-C 9 digit number that you have received from your PTTauthorities.

An Inmarsat-C mobile number is always in the range:

400000000 to 499999999

If you type a number outside this range the Transceiver will ignore it.

You should not attempt to use your equipment before you have received a mobilenumber, because the Mobile Number means that you have been registred in thedatabase for the Inmarsat-C Network.

The Transceiver only uses the mobile number when sending Message Position Reports(see the Message Handling Software Operators Guide), to indicate which Transceiveroriginated the position message.

3.4.1.1 Fast access to the Mobile Type

You can get an easy first time installation, as the Transceiver will automaticallyrecognize if the mobile number has never been entered before, and automatically bringyou to the Change Mobile Type menu.

In this situation the Mobile Number will display as

Mobile number : (unknown)

You can only change the Mobile Type the first time you enter the System Generationand the status of the Mobile Type reads (unknown). If you see a Mobile Number here,then you may skip this step as it has been performed by your dealer.

The procedure of changing the Transceiver to Maritime is shown below:




Mobile number : (unknown)

Mobile type : Illegal

Select Mobile Type:

0 Illegal

1 Landmobile

2 Maritime

Enter number > 2

Please use the Set function on the Capsat Transceiver

OK

Note that this can only be done once, as you cannot set the Mobile Number back to theunknown state. If you need to change the Mobile Type in this case, you need to contactyour dealer.



3.5 Leaving the system generationThe following procedure will bring the Transceiver back to it's normal mode ofoperation.

1. Select menu entry 0 (zero) Quit, to leave the System Generation. The TT-3020Bwill ask you to use the SetSet function and hit the ENTERENTER key.

2. The TT-3020B Capsat Transceiver will perform a self test and start its programshowing you the software version and the stand-by prompt " : ".

3. If you use a Thrane & Thrane Message Handling Software you may now hit the ESCESCkey to get back to the window menu.




4.4. Commissioning of theCommissioning of theequipmentequipment

4.1 IntroductionBefore the TT-3020B Capsat Transceiver is allowed to participate in the Inmarsat-CSystem, a commissioning procedure is required.

The commissioning procedure is just a the very first Link Test (or PerformanceVerification Test in Inmarsat terminology) that the Transceiver performs.

The Link Test automatically verifies that the TT-3020B Capsat Transceiver is capable ofboth receiving and transmitting information according to Inmarsat-C specifications. Noother tests are required.

The Inmarsat Mobile Number is needed to run the Link Test.

When a new unit is being installed, it is the responsibility of the service technician toverify that the unit is functioning properly, and that the unit is commissioned and loggedinto the Inmarsat-C System, at the end of installation.

When you power on the Transceiver for the very first time, it will automatically performa login. When the Inmarsat-C System sees this login, it will start a Link Test (orcommissioning procedure) after a short period of time.

Keep your equipment turned on and wait until the Link Test is finished before using theequipment for communications.

You should not attempt to start a Link Test yourself as you have only threecommissioning attempts, and these will be used up if you are not cautious.



4.2 The first login (commissioning)The first login first login attempt from the unit (which is automatically performed by theTransceiver) will be recognized by the Network Coordinating Station (NCS) and servednormally, (downloading a Land Earth Station (LES) network table into the Transceiver)and inform the Network Database the new unit is present and being commissioned.

After the NCS has logged the unit into the Inmarsat-C Network, it instructs anpredefined LES to start a Link Test with the unit. The LES ID is stored in Inmarsat'sdatabase of mobile units.

When the Link Test is done, the TT-3020B Capsat Transceiver is logged in andcommissioned.

4.3 Overview of a Link TestThe Link Test consist of three parts:

² Message Reception Test

² Message Transmission Test and

² Distress Test.

The TT-3020B will ask you to perform a manual Distress Test but if you ignore therequest the Transceiver will automatically send the Distress Test after 2 minutes.

In the end of the test the Transceiver will receive the link test results.




4.4 Details of a Link TestAs the first login performed by the Transceiver will cause the Commissioning (LinkTest) to take place. You should not try to start the link test yourself or try to send anymessages. If you do so, the NCS may find that your Transceiver does not respond to thecommissioning announcement, and will consequently change the status of your unit toBarred, and you will no longer be permitted to use the system.

After a while you will see a message on your screen and on your printer saying:

Link Test started

and when the MAIL indicator on the TT-3020B frontpanel starts flashing, the receive testhas commenced.

A test message is then received from the LES by the Transceiver.

After the MAIL indicator has turned OFF, the transmission test begins.

The SEND indicator starts flashing and after a while it will light continuously (the data isbeing transmitted) and then starts flashing again.

The SEND indicator will turn OFF when the protocol has finished.

The Transceiver will request you to perform a distress test. If you ignore this requestthe Transceiver will automatically send the Distress Test for you after 2 minutes, and theALARM indicator on the frontpanel will start blinking. When the distress has beenacknowledged by the LES the indicator will be on permanently.

If your Transceiver has been configured as Maritime, you will be prompted to send adistress and you must do so before the message disappears from the screen of theMessage Handling Program (if you do not use a Thrane & Thrane Message HandlingProgram, you must send the distress alert within 2 minutes after you receive theprompt). If you send a Distress yourself you will see the message "Distress issued andput in queue". You can ignore this.The printer will give an acknowledgement that the distress has been sent.After a successful distress transmission the printer will report this

The Transceiver now will wait for the test results to arrive from the LES, andacknowledge the reception of these by a short transmission (burst).

When receiving the results the screen will display:

- Link Test finished

and the results will be printed out.

The results of the test can also be viewed with:

- OPTION - LINK TEST



To reset the red ALARM indicator, press the ALARM button only on the Transceiverfrontpanel for 5 seconds.

4.5 Commissioned statusWhen the commisioning procedure has been completed, the Transceiver will store thisstatus in it's non-volatile EEPROM memory.

A special feature of the Transceiver is that when it is commissioned it will check itscurrent login status when powered on.

If it is logged out, it will automatically issue a login to the last used NCS TDM.

4.6 Uncommissioned statusThough your TT-3020B Transceiver is not commissioned, it is fully capable of receivingmessages.

You are not denied permission to transmit messages by means of the TT-3020B CapsatTransceiver when your equipment is uncommissioned, but the LES will not forward yourmessages to their destinations, and a non-delivery notification is returned to you. Youmay also see the message "Your Transceiver is not commissioned" on the printer orscreen.

Any distress alerts will not be barred or rejected by the system.
