RADIOTELEX 1 Introduction 1 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: •...
1 Introduction RADIOTELEX 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 receiv- ing station). Information Sending Station: The station transmitting characters.
RADIOTELEX 1 Introduction selective 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.
RADIOTELEX 2 Operation 2 Operation 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: Switch on, and Radiotelex starts up automatically.
2 Operation RADIOTELEX 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.
RADIOTELEX 2 Operation F5 Advanced and F6 Procedures These keys are found in some coast station and sub- scriber forms. Altering the values of Advanced and Pro- cedures 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.
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.
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.

2 Operation RADIOTELEX 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’...
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.
2 Operation RADIOTELEX Backups To make a backup 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.
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 informa- tion 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.
2 Operation RADIOTELEX 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 ‘Frequen- cies’...
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”...
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.
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.
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.
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.
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.
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.
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 mes- sages appear in the lowest part of the screen.

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.
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 com- puter without an attached modem. The mo- dem software must be 2.8.0 or later, prefer- ably 2.9.0 or later.
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.
RADIOTELEX 3 Installation and configuration 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.

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.
RADIOTELEX 3 Installation and configuration 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.
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.
