3-12 0725 RADIOTELEX 1.1 1 Introduction Introduction General information Radiotelex system Radiotelex is a communication system that handles the transmission and reception of telex messages over radio. Basically the system consists of the Radiotelex software and a Radiotelex module (modem). The Radiotelex software runs on a computer of one of the following types: • • • a marine PC, a communication computer, or an ordinary PC not using Windows. GMDSS Radiotelex has been designed in accordance with relevant IMO, CCIR, and ETSI recommendations/specifications. It has been approved for shipboard installations to operate within the Global Maritime Distress and Safety System (GMDSS). The solid state disk of the computer is used for storing the system software as required by the GMDSS. Communication concept Radiotelex supports worldwide ship-to-ship, ship-to-shore, and shore-to-ship communication. Often a coast station acts as the relay between Radiotelex and an end receiver without any Radiotelex capabilities. Ship and coast stations have unique call codes; Radiotelex supports both 4- and 5-digit selcalls and 9-digit MMSI numbers. 0725 1-1 RADIOTELEX 1 Introduction 1.2 Terminology General telex terms Master The master is the calling station (not necessarily the transmitting station but the one that actually initiated the communication). Slave The slave is the called station (not necessarily the receiving station). ISS Information Sending Station: The station transmitting characters. IRS Information Receiving Station: The station receiving characters. ARQ Automatic Repetition reQuest. A telex mode where the ISS transmits three characters at a time. Between each three characters the IRS transmits one character telling the ISS to send three new characters or to repeat the last three. Only two stations can communicate when using ARQ. Other stations cannot read the communication. FEC Forward Error Correction. A telex mode where the ISS transmits three characters at a time and repeats them immediately. FEC telex is oneway communication; the transmitter of the receiver is not used at all. FEC broadcast 1-2 A broadcast FEC transmission can be received by all stations. FEC broadcast is primarily used for coast station traffic lists and news and in distress situations. 0725 RADIOTELEX FEC selective Free signal 1 Introduction A selective FEC transmission can only be received by one particular station, just like ARQ traffic. Not used very often, FEC selective may be useful if the ship is in port where it is not allowed to transmit. On its way into the port, the ship can call the coast station to inform them that all messages for the ship must now be sent in selective FEC. Thus reception is possible without using the transmitter. Coast stations often transmit a so-called free signal when a frequency is vacant. This enables Radiotelex to detect when a transmission can begin without interrupting ongoing traffic between the coast station and another ship. Radiotelex terms 0725 Subscriber A ship or an office that is not a coast station. Coast station A radio station that sends out free signals or has the capability of being used as a link between a ship and a subscriber. Procedure A procedure specifies how Radiotelex has to communicate with a specific coast station in order to carry out a transmission, e.g. an unattended store-and-forward telex transmission of a message. Station A station is either a subscriber or a coast station. Radio station A coast station or a subscriber with a radio. Ship A subscriber with a radio. Operation Methods that can be used to get a message to the destination. Examples are store-forward telefax or direct telex. Telex In Radiotelex, TELEX means ARQ telex. 1-3 1 Introduction 1-4 RADIOTELEX 0725 RADIOTELEX 2 Operation Operation 2.1 Introduction Forms and fields Radiotelex operates with two basic data entry concepts called forms and fields. As an example of a form, we shall look at the EDIT SHIP TELEX SUBSCRIBER form. To find this: 1. 2. 3. 4. 5. Switch on, and Radiotelex starts up automatically. Press F6 Subscriber. Select New subscriber. Type in the subscriber name, e.g. ‘M/S MARY’. Select F2 Ship telex. The EDIT SHIP TELEX SUBSCRIBER form appears: A form consists of one of more fields. In the EDIT SHIP TELEX SUBSCRIBER form, there are three, each line being one field: 0725 2-1 RADIOTELEX 2 Operation Function keys Radiotelex uses function keys as a means of selection. Each form contains a number of function keys which may or may not be present in other forms. Below we shall have a look at the function keys in the EDIT SHIP TELEX SUBSCRIBER form shown above. Also, we shall see how some function keys always have the same function. Finally, a later chapter will show that the TELEX and FEC terminals have two sets of function keys – ‘standby’/not ‘standby’. For now, let us once again turn to the EDIT SHIP TELEX SUBSCRIBER form, which contains the following function keys: Below the function of each key is described: F10 Returns to the previous screen. F1 Modify field By pressing F1, a list of possible values for the current field will pop up. An appropriate value can then be selected from the list. F2 Save Pressing this key saves the form. When pressing F10 in a form which has been edited and whose values have changed, the radiotelex system asks if the changes should be saved. F3 Delete Generally deletes the whole field if this contains the F1 Modify field function. 2-2 0725 RADIOTELEX 2 Operation F5 Advanced and F6 Procedures These keys are found in some coast station and subscriber forms. Altering the values of Advanced and Procedures requires a password. F7 Default This function may be found in other forms. It inserts default values in the fields where such values are appropriate. General functions A few keys always have the same function(s): F1 Selects in a list or menu, or modifies a field. In most cases, the right arrow key can be used instead of F1. F10 Returns to the previous screen, or – from the TELEX and FEC terminals – exits Radiotelex. In most cases, the left arrow key can be used instead of F10. Space bar Corresponds to the F1 and right arrow keys in selection lists (e.g. a list of messages). Shift-F1 and F11 In addition to the information in this manual, Radiotelex offers detailed on-line help information. To get help at any time, press either shift-F1 or F11 in the relevant field. Fast keys Fast keys are key combinations of the Alt key and a function key, e.g. F1. Pressing the Alt key pops up a table of fast keys. Fast keys may be changed in the setup part of Radiotelex. There are also a few short cuts assigned to the Ctrl key. For instance, pressing Ctrl-C takes you to the TELEX terminal or FEC terminal dependent on which part of Radiotelex was used previously. The function of the Alt key is always the same. The function of the Ctrl key, however, depends on the situation. Thus, when communication is taking place, Ctrl-L toggles logging. 0725 2-3 2 Operation RADIOTELEX Password As already mentioned, certain areas of Radiotelex are protected by a password. Such areas can only be altered by technicians who know the password. Still, even though the user of the system cannot change the data of the program, these can always be viewed. The system will tell you when a password is required to change some data: To continue without a password press F3 View only. 2.2 Terminals The TELEX and FEC terminals are the centres of Radiotelex. From them, the various functions of the system can be reached: To swap between the TELEX and FEC terminals select: 1. F8 Menus F1 Mode 2. 3. The appropriate terminal. 2-4 0725 RADIOTELEX 2 Operation The terminals simulate the printer paper of an old-style TELEX terminal. Thus, characters that have been received or transmitted are shown. Radiotelex has a terminal for both ARQ (called TELEX in the Radiotelex terminology) and FEC traffic. The TELEX and FEC terminals are operated in the same way, and the differences are few. The terminals are the centres where all transmissions and receptions are initiated, and all actions are chosen. The FEC terminal, however, will probably not be used much. It is recommended that FEC scans to catch news broadcasts and traffic lists are set up from F4 Rx in the TELEX terminal. The news and traffic lists are normally printed, while FEC transmissions are rarely used. 2.3 Terminal function keys The terminals operate with two sets of function keys. Which set is used depends on whether Radiotelex is ‘standby’ (not receiving, calling or transmitting), or NOT ‘standby’. Only the TELEX terminal is described below, but the FEC terminal is very similar. Function keys when ‘standby’ Rx 0725 2-5 RADIOTELEX 2 Operation F1 Terminal functions A window with the ‘standby’ function keys pops up. Unlike the other function keys, F1 Terminal functions is the same whether ‘standby’ or not. It is useful when Radiotelex is not ‘stand-by’ since the function keys on the screen shown above are then the not ‘standby’ function key set (shown below). You can select among the following: F10 Return to DOS 2-6 F2 Distress Distress mode. F3 TX Transmission-related functions (setting up, deleting, table of scheduled transmissions etc.). F4 Rx Receive-related functions (setting up an Rx session, enabling/disabling Rx etc.). F5 Messages Message handling (creating, copying, deleting etc.). Messages not logged. F6 Subscriber Subscriber handling (creating, copying, deleting etc.). F7 View Selects between the following views: • TELEX connection • TELEX errors • System status • Current scanning • Logged TELEX messages • Traffic history F8 Menus Selects between the following menus: • Mode • Setup • Service • Guidance Exits Radiotelex, performing a backup if wanted. 0725 RADIOTELEX 2 Operation Function keys when not ‘standby’ F1 Terminal functions The ‘standby’ function keys, described above, become available in a pop-up window. F2 Bell Transmits the special symbol bell. F3 Time Transmits the current time. F4 Date Transmits the current date. F5 Message Transmission of a message. F6 WRU ‘Who are you?’ The other station is asked to transmit its answer back. F7 De Transmits your own answer back. F8 Over Changes direction. F9 Break Breaks the connection. The above function keys are active dependent on the situation. If Radiotelex is the IRS (Information Receiving Station), the keys involving transmission (F2 to F7) are not available. 0725 2-7 2 Operation 2.4 RADIOTELEX Backups To make a backup 1. 2. From one of the terminals, leave Radiotelex by pressing F10. Start up again. Backups can only be made when leaving Radiotelex. When you press F10 at the terminal to leave Radiotelex, you will be prompted to make a backup. Furthermore, when starting up, Radiotelex will ask whether or not previously backed-up data are to be restored. Background information on backups In order to meet the GMDSS safety requirements, Radiotelex is always delivered on a non-volatile board like an EPROM board or flash EPROM board. This ensures that the Radiotelex program and its initial settings cannot be lost due to power failure or power off. Furthermore these data cannot be erased by accident. Data (e.g. messages) cannot be saved on this board. In order to save data temporarily, Radiotelex creates a RAM disk. A RAM disk is used exactly like a normal disk drive, but is a volatile medium: The contents are erased in case of power failure and when the power is switched off. The RAM disk only provides temporary storage. Therefore, before the power is switched off, it is necessary to perform backups to ensure that data are not lost but saved on the backup diskette. The non-volatile board on which Radiotelex is delivered, ensures that it is always possible to communicate using Radiotelex. So even if a backup diskette that is lost or out of order is an inconvenience, it does not enforce a communication breakdown. Backup policy Backups should be made regularly, e.g. once every 24 hours. Backups should always be made when subscribers have been created, the setup has been changed, or anything else of importance has taken place. In order to keep the backup as short as possible, it is advisable to check the logged messages (both TELEX and FEC) and the traffic history before making 2-8 0725 RADIOTELEX 2 Operation the backup. Then, delete the logged messages that you do not consider important. Also, delete the traffic history unless it contains important information to be kept. Radiotelex on hard disk The Radiotelex software can be installed on a hard disk as a supplement to the non-volatile board. The hard disk delivered from the factory is suitable for use in a maritime environment. However, as a hard disk cannot be completely reliable, the non-volatile board is always necessary. Data are stored on the hard disk automatically. Therefore, when the Radiotelex program is executed from the hard disk, backup procedures are not necessary. However, since the hard disk could crash, it is recommended to make a backup to a diskette at an initial stage when relevant subscribers have been created and setup changes have been performed. 2.5 Transmission Radiotelex only supports manual transmissions. There is no scanning of a free signal but Radiotelex sets up the transmitter frequency enabling you to hear when the channel is vacant and the transmission can be initiated. Furthermore you have to type in the call code yourself. The manual transmission form consists of the following fields: 0725 2-9 RADIOTELEX 2 Operation Call code Call code of the destination. Channel type Choose between the following options: • • • • ITU intership channel ITU coast station channel Frequencies ITU distress and safety frequencies. Channel Type the channel number. Not available when ‘Frequencies’ has been chosen as channel type. RX frequency Type the RX frequency. Only available when ‘Frequencies’ has been chosen as channel type. TX frequency Type the TX frequency. Only available when ‘Frequencies’ has been chosen as channel type. When channel or frequency fields have been filled with valid values, the transceiver is set up with these frequencies. Thus listening to the TX frequency is enabled. Simply alter the channel or frequency fields until a free channel has been located. 2.6 Scanning In order to receive an incoming telex call you have to set up an Rx session. Radiotelex only supports a single manually initiated Rx session and it only supports scanning of a single frequency. The method for setting up an Rx session is very similar to performing a manual transmission. The first step to do is to press F4 Rx in the terminal. The Rx window will list the current Rx session (if any). To create a new session (or modify the existing session) press F1 Modify Receiving. In the next window just select the station or subscriber of interest and the channel to scan. Note that only a single frequency can be selected. Press F2 Save when you have selected the station/subscriber and the frequency. Radiotelex will scan the selected channel continuously until the scheduled Rx is either deleted or manually disabled (in the F5 Rx control menu). 2-10 0725 RADIOTELEX 2 Operation Note that a manual transmission has higher priority than the Rx session. This implies that the Rx session will be “disabled” during the transmission session. The Rx will be restarted once the transmission session is terminated. You may need to update or create a new station/subscriber if the default stations provided by Radiotelex does not list the frequency of interest (the two default stations “ITU Ship Station Channels” and “ITU Coast Station Channels” only show a subset of the valid ITU channels). 2.7 Message handling ‘Message handling’ is used to type in messages before transmission, possibly in order to perform an automatic transmission. To go to the ‘Message handling’ form In the terminal, press F5 Message. To write a new message select ‘New message’. To modify an existing message select the relevant message. An existing message can be edited, copied, deleted, renamed and printed. Also, as explained in the following, messages can be imported and exported: 0725 2-11 2 Operation RADIOTELEX Import of message To import a DOS text file to the Radiotelex message system, select F7 Import. The DOS file is specified by browsing the DOS directories. Export of message It is also possible to export – i.e. copy to a DOS file – an existing message. The exported file can e.g. be imported by a word processor or copied to another computer. Selecting F8 Export allows you to specify directory and DOS file name for the selected message,. 2.8 Subscriber handling To see a list of existing subscribers press F6 at the terminal. Radiotelex distinguishes between coast stations and subscribers. A subscriber is a station without coast station capabilities, e.g. a land telex station or a ship. To create a new subscriber select ‘New subscriber’. To modify an existing subscriber move the cursor bar to the relevant subscriber and select F1 Edit TELEX subscriber. 2-12 0725 RADIOTELEX 2 Operation Subscriber edition in general A subscriber may consist of several parts, e.g. a land telex part or a ship telex part. As some subscriber parts are more complex than others, the edition of a subscriber part has been divided into three sections where appropriate. These sections are: General partThese general values will always have to be filled in. When a subscriber part has been chosen, the general values are accessed in a form. Advanced This is a set of default values that will rarely have to be changed. Procedures Procedures are used to perform automatic transmissions. A procedure provides a list of instructions on how to communicate to a specific station in special cases. Normally no procedures are defined for a subscriber. Advanced and Procedures are accessed from the form containing the general values. Furthermore, Advanced and Procedures are passwordprotected. Still, the contents can always be viewed. Subscriber parts A subscriber consists of several parts. The following subscriber parts can be defined: Land telex, ship telex, telefax, telephone modem, voice phone, voice bank phone, Radiotelex letter, telegram and satellite. However, in most cases only one or two of the parts will be detailed for each subscriber. When the properties of a subscriber change, e.g. if a fax number has to be added to the subscriber, it is easy to edit the existing subscriber, adding the relevant details. To delete a part of a subscriber select the relevant part and press F3 Delete in the form describing the part. In order to transmit to a subscriber, it is necessary that a coast station supports the communication form (except for ship telex). For instance the satellite part is not used since coast stations cannot handle this even though it has been defined in the recommendations. Refer to the section about land telex below. Below some of the subscriber parts are described. Please refer to the Radiotelex on-line help as well. 0725 2-13 2 Operation RADIOTELEX Land telex Land telex has two fields that need to be filled in: country code and telex number. The country code field is described in the chapter ‘Coast station setup’ in the last part of this manual – ‘Configuration’. The telex number is the subscriber’s telex number without any land telex country code. To reach an Inmarsat A, B or C station (both ship and land stations), enter the country abbreviation ‘SAT’ and the telex number of the station. Since the country abbreviation ‘SAT’ is not used by any coast station, during the transmission setup Radiotelex will ask for a direction code. Enter the Inmarsat region code (e.g. 581 for Atlantic Ocean Region East). Ship telex It is sufficient to enter the master frequencies. The slave frequencies are optional. For information on the difference between the master and slave frequencies, please refer to the chapter ‘Coast station setup’ in the last part of this manual – ‘Configuration’. The on-line help may be useful as well. Satellite The satellite option is not useful since it is not supported by many coast stations (if any at all). To transmit a telex to an Inmarsat A, B or C ship, please refer to the above description of land telex. Hiding and recovering subscribers Subscribers that are not used for a long period of time can be hidden instead of deleted. When they are needed again, they can be recovered. To hide a subscriber move the cursor bar to the relevant subscriber, and select F5 Hide. To recover a subscriber select F6 Recover for a list of hidden subscribers, and select the subscriber to be recovered. 2.9 VIEW function The F7 View function provides information that may be useful at different points. The function differs a bit dependent on the mode. 2-14 0725 RADIOTELEX 2 Operation View is not only available in the terminal. It can also be used in e.g. the receive and transmission parts of Radiotelex. Pressing F7 View in the TELEX part of the system will display a number of selectable items. These are described below. The corresponding View items of the FEC part of the system are quite similar to the ones shown here: TELEX connection shows information on the present or latest TELEX (ARQ) connection. This information includes: subscriber, coast station and frequencies. TELEX errors details the quality of the connection by giving information about the number of repetitions. Both the total number and the number relative to the total of transmitted and received characters are shown. System status contains information about the schedules, modem and frequencies. Logged TELEX messages keeps up to a hundred logged TELEX messages. When the total reaches one hundred, the oldest message is deleted every time a new message is logged. In the setup part of Radiotelex, it can be specified what information is to be logged. Similarly, Radiotelex can log a hundred FEC messages and a hundred distress messages. Traffic history details what communication took place when. If, for instance, a message needs several attempts to be transmitted successfully, the traffic history will detail each attempt. 2.10 Distress The telex distress frequencies are not scanned by coast stations. A distress transmission must always be initiated by the DSC function. This will set up the frequencies of the radio as indicated in the DSC call or reply. When the distress transmission has been set up by the DSC function and the communication has begun, the parties communicating can decide to use another frequency without DSC usage. 0725 2-15 2 Operation RADIOTELEX When Radiotelex is communicating, distress mode cannot be entered. Break the connection first, then select distress mode. Or more likely, just make the DSC distress call and Radiotelex will stop communicating since DSC has priority. When entering distress mode, all scans and transmissions set up outside distress mode are disabled. That is because distress mode is a special shell disclosing all other activities – only the distress activity takes place. All communication is both printed and logged no matter what the setup is like outside distress mode. Also, the retry schedule is disabled. However, the TELEX (ARQ) terminal and the FEC terminal are used even in distress mode. The same goes for ‘Message handling’, which is not affected either. When exitting distress mode, schedules (scans and transmissions) set up outside distress mode are restored. Distress mode To enter distress mode • press Alt-D (anywhere) or: • press F2 (in the TELEX or FEC terminals) Note: Distress may only be used when your ship is in distress. If participating in another ship’s distress communication, do not enter distress mode but use the normal facilities. To exit distress mode press Alt-D. 2-16 0725 RADIOTELEX 2 Operation Distress Transmission To set up a broadcast FEC or selective FEC transmission select F2 TX FEC. To set up an ARQ transmission select F3 TX ARQ. Even though distress mode is a special shell that discloses all other activities, the normal FEC and TELEX (ARQ) terminals respectively are used for this communication. To change the frequency to be transmitted on select F4 Scan/Frq. F5 Message contains the normal message handling. Therefore it is possible to write a distress message beforehand and then just edit to fill in the last details if the distress situation occurs. Distress SCAN function F4 Scan/Frq allows for simple selection of a distress frequency. Distress VIEW function This function resembles the View function found outside distress mode. However, in distress mode only System status, and Logged distress messages are available. 0725 2-17 2 Operation RADIOTELEX Similar to TELEX and FEC, only a hundred distress messages can be logged. After that, the oldest distress message is overwritten when a new message is logged. 2.11 Status messages Below various status messages of Radiotelex are explained. These messages appear in the lowest part of the screen. No usable COM ports available No serial communication ports are available. If any are installed, they are used by other hardware like e.g. a mouse. Searching for external equipment Searching for the Radiotelex board. External equipment found The Radiotelex board has been located. No external equipment found yet ! The Radiotelex board has not yet been found. The connection to modem has been lost ! The Radiotelex program cannot communicate with the Radiotelex modem any longer. First, check cable connections between the computer and the modem. Then, exit Radiotelex and start again. Connecting to modem ... The modem has been located, and the communication works fine. Initializing information between the computer and the modem is exchanged. The modem is in ‘standby’ state Radiotelex is not calling, transmitting, receiving or scanning. The modem is idle. Fatal error from modem (read the Traffic History) – connection locked ! The Radiotelex program and the modem are out of synchronization. Please read the Traffic History, and report to your dealer. Exit Radiotelex and restart. Updating modem for transmission ... A transmission has been initiated. The transmission details are currently 2-18 0725 RADIOTELEX 2 Operation being transferred from the computer to the modem, and the modem is setting up the radio. Modem is calling ... Radiotelex is calling a coast or a ship station. TELEX communication in progress ! Telex (ARQ) communication is in progress. The radio link between the two involved radios and modems has been established, and actual communication has begun or is about to begin. TELEX communication requires attention! Go to TELEX (ARQ) terminal Telex (ARQ) communication is now taking place. The communication is not an automatic telex transmission that can take place unattended. Radiotelex is not in the TELEX (ARQ) terminal currently: Therefore, this status message tells the operator to go to the TELEX (ARQ) terminal and pay attention to the communication. Reception in progress In a telex (ARQ) connection, Radiotelex is now receiving. Only the F8 Over and F9 Break function keys are available. Changing direction ... The operator has pressed F8 Over to change the direction. Text transmission allowed The operator can now transmit any text by typing the text manually, or by pressing F5 Message to select an already typed in message. All function keys of the terminal can be used. TELEX rephasing in progress ! An MF/HF radio is not always an easy medium to deal with. If a radio connection is bad and repetition has occurred 32 times in a row, rephasing may begin. During rephasing, the two modems try to synchronize again. The transmission has failed ! The call to the station did not succeed, or possibly a message was not transmitted completely. This status message is also issued if F9 Break is pressed. Break in progress A break has been issued by Radiotelex. 0725 2-19 2 Operation RADIOTELEX FEC reception in progress ! FEC communication is now being received. The transmission being received can be a broadcast FEC transmission or a selective FEC transmission to your ship. The modem is disabled The modem has been disabled. See explanation below. Modem disabled by function Rx Control Scanning has been disabled by the scan control function. Scanning can be enabled again in the terminal function F4 Rx. When the modem is disabled, all scanning is stopped, and transmission cannot take place. Scanning stopped, enabling listening to own TX frequency A transmission to a ship is being set up. In order to let the operator check if the channel is vacant, all scanning has been stopped, and the radio has been set up with the TX frequency in the receiver. TELEX messages logged - # Number of logged TELEX messages. The maximum is a hundred. If a hundred TELEX messages have been logged, the next time a message is logged, the oldest message is deleted. For further information, please refer to ‘TELEX log setup’ in the ‘Configuration’ section. FEC messages logged - # Number of logged FEC messages. The maximum is a hundred. If a hundred FEC messages have been logged, next time a message is logged, the oldest message is deleted. For further information, please refer to ‘FEC log setup’ in the ‘Configuration’ section. The radio is busy ! Right after switching on, in order to have a frequency stability of ± 10 Hz, the radio has to warm up. During this warm-up, the above message is issued. If the radio is being configured, the radio is also busy. When used for telephony, the status message ‘The radio is not ready’ is shown. The radio is controlled by DSC ! The DSC function has taken control, and Radiotelex has stopped all scanning and all transmission. 2-20 0725 RADIOTELEX 2 Operation The radio is not ready ! The control unit is not in telex mode, or the handset is off hook. The radio is disconnected ! No communication with the radio. The radio may be switched off. Transmission to connected FEC subscriber. Go to FEC terminal. FEC transmission is now taking place. Radiotelex is not in the FEC terminal currently. Therefore, this status message tells the operator to go to the FEC terminal to pay attention to the transmission. The modem is listening to a single frequency Listening for traffic. A scan containing only a single frequency has been set up. Secret reception in progress ! Radiotelex offers the possibility of hiding the communication. Refer to TELEX secret setup for further details. Distress messages logged - # In distress mode, all communication is logged. Only a hundred messages are kept in the log. The oldest logged message will then be deleted when a new one is logged. The modem is listening to a single frequency for FEC and ARQ In distress mode, Radiotelex listens for both FEC and ARQ traffic automatically. 0725 2-21 2 Operation 2-22 RADIOTELEX 0725 RADIOTELEX 3.1 3 Installation and configuration Installation and configuration Installation System wirings Below system wirings are shown for different configurations. Setting time and date Information on date and time is shown in the upper right corner of the screen. The system uses date and time to stamp received and sent messages. Before installation or execution, the date and time stamps can be checked and set. This is done by means of the two DOS commands ‘time’ and ‘date’. Setting time If Radiotelex is running, return to DOS by exitting Radiotelex. At the DOS prompt, write ‘time’ and press enter. DOS replies e.g.: Current time is 2:49:02.65p Enter new time: _ If the time is correct, just press enter. Otherwise enter a new time, e.g. 8:44p, and press enter. Setting date If Radiotelex is running, return to DOS by exitting Radiotelex. At the DOS prompt, write: ‘date’ and press enter. DOS replies e.g.: Current date is Thu 12-19-1996 Enter new date (mm-dd-yy): _ If the date is correct, just press enter. Otherwise enter a new date, e.g. 1220-96, and press enter. 0725 3-1 3 Installation and configuration RADIOTELEX Installation on flash EPROM board The flash memory board is a non-volatile medium, which complies with the GMDSS requirements. The flash memory board facilitates installation. Insert the Radiotelex flash memory installation diskette in the computer, and type: a: [b:] enter install enter Any software applications present on the flash memory board are now deleted, and the Radiotelex program is installed. This process may take up to fifteen minutes. Installation on hard disk Normally, the Radiotelex program is installed on a non-volatile medium, like the flash memory board. A RAM disk is used for temporary storage, and it is necessary to make backups. However, the Radiotelex program can also be installed on a hard disk. In that case, it is not necessary to make backups. Still, as a hard disk can crash, the non-volatile installation is necessary to comply with the requirements of the GMDSS. Thus, after the installation has been finished, it is advisable to make one backup diskette, as described in this chapter. If it becomes necessary to use the non-volatile installation (e.g. the flash memory board), this backup diskette can be used when Radiotelex prompts to restore. This ensures that the basic installation is the same as when used on the hard disk. 3-2 0725 RADIOTELEX 3 Installation and configuration To install the Radiotelex program change the home directory and where the Radiotelex executable file should be installed, by means of F3 and F2 respectively. When satisfied, start the installation by pressing F1. Config.sys and Autoexec.bat The config.sys and autoexec.bat files should be configured to provide maximum available memory and to use smartdrv. Below examples of config.sys and autoexec.bat are shown. These may need some modification, e.g. it is assumed that only one hard disk is available and that a network is not installed (lastdrive=c). Config.sys device=c:\dos\himem.sys device=c:\dos\emm386.exe noems dos=high,umb files=20 buffers=40 shell=c:\dos\command.com c:\dos /e:256 /p lastdrive=c fcbs=1 Autoexec.bat @echo off loadhigh c:\dos\fastopen c: loadhigh c:\dos\doskey loadhigh c:\dos\smartdrv /x prompt $p$g path c:\dos;c:\radiotlx set temp=c:\dos Modem setup The modem setup requires various information. To supply information press: F8 Menus. 1. 2. F2 Setup. F5 Modem Setup. 3. 0725 3-3 3 Installation and configuration RADIOTELEX To save information press F2 Save. The values are locked by the modem. Unless a factory reset is performed, the values cannot be altered. Note: The non-standard answer-back field must also contain appropriate letter/figure shifts and other special characters available in the F1 Modify field. Parts of the above fields are described below. Please refer to the on-line help as well. Answer backs in Radiotelex Dependent on the situation and the setup, Radiotelex transmits one of three possible answer backs: 1) 2) 3) 5-digit call code + abbreviated id + X MMSI number + abbreviated id + X Non-standard answer back Below is a description of which answer back will be used when. Call code and MMSI number in answer back In the automatically generated answer back, the call code or the MMSI number is part of the answer back. If only one of the two is specified, Radiotelex uses the specified one in the generation of the answer back. 3-4 0725 RADIOTELEX 3 Installation and configuration However, both the 5-digit call code and the MMSI number may be specified. In that case, Radiotelex uses the 5-digit call code or the MMSI number in the answer back, dependent on the call code used when the connection was established. If Radiotelex called or was called using a 5-digit call code, Radiotelex transmits its 5-digit call code in the answer back. If an MMSI number was used, Radiotelex transmits its MMSI number in the answer back. Abbreviated ID in answer back The abbreviated ID is used when generating the answer back of M/S ULYSSES automatically. The standard answer back consists of: • • • • • • • • • • Figure shift Carriage return Line feed 5 digit call code or MMSI number Letter shift Space Abbreviated ID Space Letter shifts to bring the total length up to 20 Non-standard answer back In general coast stations identify a ship by the answer back that Radiotelex generates automatically. However, Radiotelex uses the non-standard answer back in connection with coast stations that do not follow recommendations and thus cannot identify a ship by the answer back generated automatically by Radiotelex. In order to force Radiotelex to transmit the non-standard answer back in connection with a specific coast station, it is necessary to edit the coast station in the setup part of Radiotelex. In the coast station setup, the field ‘Nonstandard answer-back used’ must be set to ‘Yes’. This has been done for Maritex coast stations already. Only when this field has been set to ‘Yes’ does Radiotelex transmit the non-standard answer back. In all other situations Radiotelex transmits the automatically generated answer back. Please note that the non-standard answer-back field must contain appropriate letter/figure shifts and other special characters available in the F1 Modify field. Radiotelex does not modify the specified non-standard answer back in any way. 0725 3-5 RADIOTELEX 3 Installation and configuration Radio interface The radio interface has three possible values: Extended (T+Bus) Default. Standard (T+Bus, one way) Not used. None Used for demonstration purposes on a computer without an attached modem. The modem software must be 2.8.0 or later, preferably 2.9.0 or later. Factory reset The values in the modem are locked and can only be reset by a factory reset. Please refer to the relevant hardware manual for more information. Printer setup The printer setup is located in: 1. 2. 3. 4. F8 Menus F2 Setup F6 Computer F2 Printer Setup Please note that if a printer using a paper roll is used, as is the case with the default printer, the paper length must be set to zero. Ship name The ship name possibly including the call sign. Setting up subscribers Create ship owner and dealer subscribers. Hiding subscribers and coast stations Subscribers and coast stations that are not used can be hidden. This makes selection lists shorter without deleting stations. They can be recovered if necessary. See further information in the ‘Configuration’ section. 3-6 0725 RADIOTELEX 3 Installation and configuration Backup installation To have a diskette with the basic installation, a backup should be made by leaving Radiotelex when the installation has been finished. Now restart Radiotelex, restoring the previously made backup diskette. Then perform another backup on another diskette by leaving Radiotelex again. There are now two backup diskettes: One for daily operation, and another one to be used if the former is faulty or lost. 3.2 Configuration Coast station setup For a list of existing coast stations select: 1. F8 Menus F2 Setup 2. 3. F1 Coast station. To create a new coast station select ‘New coast station’. 0725 3-7 3 Installation and configuration RADIOTELEX To modify an existing coast station move the cursor bar to the relevant coast station, and select F1 Edit coast station. Hiding and recovering coast stations Coast stations that are not used for a long period of time can be hidden instead of deleted. When they are needed again, they can be recovered and used by Radiotelex again. To hide a coast station move the cursor bar to the relevant coast station, and select F5 Hide. To recover a coast station select F6 Recover for a list of hidden coast stations, and select the coast station to be recovered. Import of coast station If a coast station has been deleted and is to be used again, or a new coast station is to be used, it can be imported from a Radiotelex backup file. SHOW: Coast station setup To view the capabilities of a particular coast station, move the cursor bar to that station, and press F8 Show setup. Coast station edition General information Coast station edition has been divided into three parts. General part The general values will always have to be filled in. When a coast station part has been chosen, these values are accessed in a form Advanced Radiotelex provides a set of default values. These will rarely have to be changed. Procedures Procedures are used to perform automatic transmission. A procedure provides a list of instructions specifying how your station is to be communicated to in connection with various coast station commands like DIRTLX, TLX etc. 3-8 0725 RADIOTELEX 3 Installation and configuration Right after the selection of a coast station, the general part is accessed. (If ‘New coast station’ is selected, the name of the new coast station will have to be filled in first). The sections Advanced and Procedures can be accessed from the form containing the general values. Both Advanced and Procedures are password protected, but the contents can always be viewed. Performing coast station edition The following is a description of some of the fields of the general coast station form shown above. Please refer to the on-line help for further information. Country abbreviation: The country abbreviation must comply with the maritime abbreviations used in the list of coast stations. The country abbreviation is used during the setup of a transmission to a land telex subscriber. If the land telex subscriber and the coast station used as a link between Radiotelex and the subscriber do not reside in the same country, Radiotelex will ask for a land telex country direction code used from the coast station country to the subscriber country. This code will be prefixed the land telex subscriber number automatically during transmission. Coast station master and slave frequencies: The edition is seen from the point of view of the subscriber. The master 0725 3-9 3 Installation and configuration RADIOTELEX frequencies are used when Radiotelex is scanning the coast station for traffic since in that situation the coast station will be the caller. The slave frequencies are used when Radiotelex is calling the coast station since in that situation the coast station will be the slave station. In short, when setting up a scan of the coast station being edited, the master frequencies are used; when setting up a transmission to the coast station being edited, the slave frequencies are used. If slave frequencies are not specied, master frequencies are used when calling (and scanning for a free signal) a coast station, too. Abbreviated ID and answer back: The call code and the abbreviated ID provide the means for automatic generation of the answer back of a coast station. However, the answer back can be given explicitly in the answer back field. If this field has been filled in, this answer back will be used. Non-standard answer back used: Not all coast stations follow the recommendations when it comes to answer backs. The Swedish company Maritex, for instance, can assign subscribers a Swedish land telex number to be used as answer back. Therefore, Radiotelex needs to know whether the non- standard answer back is to be used when communicating with the coast station being edited. When the ‘Non standard answer back used field’ is set to ‘Yes’, Radiotelex non-standard answer back as specified in the modem setup is used (see the section on ‘Installation’). TELEX print setup By default all communication is printed. TELEX tape puncher setup By default the only communication punched is when Radiotelex is the slave – i.e. Radiotelex has been called by the other station. TELEX log setup By default Radiotelex logs all communication when Radiotelex is the slave. When the system has called another station – and is thus the master – only conversation is logged. That is because a message being transmitted already exists in ‘Message handling’. 3-10 0725 RADIOTELEX 3 Installation and configuration TELEX TTY setup During communication the terminal is not necessarily the active window. The TTY setup specifies how many minutes it is allowed not to be in the terminal before the communication is broken. This function only applies to conversation, and only when Radiotelex is the master. Values of zero disable the time outs. TELEX retry setup There is no guarantee that MF/HF transmissions are successful every time. The ‘hit rate’ is not like e.g. Inmarsat-C communication. That is the reason for the retry concept: If a transmission is not successful, it is stored in a retry schedule, and retransmission can be attempted at a later time. In the TELEX retry setup it can be specified how many times retransmission is to be attempted and how many minutes there are to be between each attempt. Furthermore, different values can be specified for ship calls and coast station calls. Values of zero disable the retry schedule. Note that if a transmission is broken by using F9 Break, the transmission is deleted from the retry schedule automatically. Transmissions in the retry schedule can be viewed or deleted in the transmission table available by pressing F3 TX in the terminal and then F5 TX Table. TELEX secret reception setup Secret reception may be initiated upon the reception of a configurable sequence of characters. The secrecy continues until the connection is broken or, if specified, either of two programmable sequences of characters are received. During secret reception nothing is printed. Also, the keyboard cannot be used to send anything to the connected subscriber. Secret reception is logged in a special password protected file queue irrespective of the configuration of the normal log. 0725 3-11 3 Installation and configuration RADIOTELEX FEC TTY setup During communication the active window is not necessarily the terminal. The TTY setup specifies how many minutes it is allowed not to be in the terminal before the communication is broken. The functionality applies to conversation only, and only if Radiotelex is the master. Values of zero disable the time out. Printer setup Selection of printer type and paper length. If the paper roll is used, set paper length to zero. The default parallel port is LPT1. If several parallel ports are available, another port can be selected. A serial printer cannot be used. Fast key setup Radiotelex enables the use of fast keys (short cuts). A default set of fast keys is provided, but if you find that there is a specific function you use quite often, you can set up a fast key for this specific function. It will probably be an advantage to keep the Alt-F1 TELEX (ARQ) terminal and the Alt-F2 FEC terminal, but the rest can be configured as you wish. The fast key for getting into distress mode can also be changed. The default value is Alt-D. To go to the ‘Fast-key setup’ select: 1. 2. 3. 4. 3-12 F8 Menus. F2 Setup. F6 Computer. F2 Fast-key setup. 0725 RADIOTELEX 3 Installation and configuration To configure a fast key 1. In the ‘Fast-key setup’, move the cursor bar to the desired place by means of arrow up/down. 2. Select the F3 Learn fast-key, which will take you to the terminal. 3. Now use the keys as usual until you are at the point in the program where you want the fast key to take you. 4. Press Esc to terminate the configuration. To change a fast key title 1. In the ‘Fast-key setup’, move the cursor bar to the desired place by means of arrow up/down. 2. Select F2 Change title. To abort during configuration press Ctrl-C. 0725 3-13 3 Installation and configuration 3-14 RADIOTELEX 0725 TT-98-125586-A Issue: A/0725 Thrane & Thrane A/S • info@thrane.com • www.thrane.com
