THE STATE OF THE ART
Tiger Shark has been accurately designed to satisfy the most demanding requirements in FM Stereo generation and advanced RDS/RBDS encoding. It is built with the best cutting-edge technology: surface-mount components and multi-layer circuit boards keep the signal path safe from any issue, providing the purest modulation quality. Its digital architecture guarantees long term reliability and easy firmware updates, directly on field or from remote. Tiger Shark is a top-class RDS/RBDS and Stereo Generator machine. It has been designed to provide every custom requirement if a structured FM network, especially managing advanced machine control and signal changeover, using a PC and webserver interface. Tiger Shark supports the most advanced RDS dynamic services, including TMC, ODA, IH, TDC and EWS. In addition to standard CENELEC methods, RDS programming has been enriched with larger PS and RT sets (also available in dynamic mode) with powerful scheduling capabilities.
GPS satellite receiver, such as our Sat Time Synchronizer, can broadcast local time info as part of the RDS data. RDS service carries also 4 IH (InHouse Application) remote controls, that can be used to start advertising breaks on distant networks, to split broadcasting areas, to activate / deactivate recorders etc.. Tiger Shark communication features have been enforced with comprehensive remotecontrol via RS232, RS485, modem or TCP/IP: Its built-in, passwordprotected server is compatible with FTP, Telnet, SNMP, HTTP and UECP protocols. It can be easily interfaced to various Automation Systems and offers an ASCII protocol for broadcast song/artist information. In case of alarms, it supports SNMP alerting for automation systems, and eventually SMS notification (by a GSM modem connection).

7 FIRST INSTALLATION RECOMMENDATIONS
7.1 POWER SUPPLY CABLE
A power supply cable of approx. 2 mt length is supplied with the device, which has a moulded IEC plug attached – this is a legal requirement. The type of plug for the power supply depends on the country in which it is delivered.
If for any reason, you need to use this appliance with a different plug, you should use the following wiring guidelines in replacing the exsisting plug with the new one:
Earth
Green, or green and yellow
Neutral (N)
Blue
Live (L)
Brown
Supply cables should be laid in such a manner that one does not step or walk on them. They should not be squashed by any objects.
THIS EQUIPMENT MUST BE EARTHED.
The chassis is always connected to mains earth to ensure your safety: check your mains wiring and earthing before switching on.
7.2 AC MAINS VOLTAGE SETTING (230 V / 115 V)
BE SURE THAT THE UNIT IS SET TO THE CORRECT MAINS/LINE VOLTAGE FOR YOUR COUNTRY BEFORE PLUGGING IT INTO THE WALL OUTLET !
The actual Mains voltage is indicated on the label stuck on the equipment closure. Should the type of power at the operation location not be known, please contact your dealer or electricity company.
If, for some reason, the unit is to be operated at a mains input voltage which is different to that as supplied, you need to switch the voltage selector on the right side of the unit. You also need to replace the AC main fuse, according to information provided on the external label or on the Technical Specifications table at the end of this user manual.
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, ALWAYS DISCONNECT THE AC MAINS CABLE BEFORE ALTERING THE CHANGE-OVER SWITCH. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
ENG
Axel Technology srl www.axeltechnology.com | FIRST INSTALLATION RECOMMENDATIONS
17
7.3 FUSE REPLACEMENT
The power supply socket has an integral fuse drawer containing the AC power fuse and a spare, both of the same value.
BEFORE REPLACING THE POWER FUSE, MAKE SURE YOU HAVE THE RIGHT TYPE OF FUSE FOR THE VOLTAGE TO BE PROTECTED. USING WRONG FUSE TYPE WILL RESULT IN INSUFFICIENT PROTECTION.
Make sure that the power is switched off and the power cable is disconnected from the equipment.
a. Open the fuse drawer using a small blade screwdriver.
b. Replace the fuse located at the internal position
c. Push the fuse socket back into the original position (a.)
Perform the set-up under static control conditions. Static charges are likely to completely destroy one or more of the CMOS semiconductors employed in the unit. Static damage will not be covered under warranty. Basic damage prevention consists of minimizing generation, discharging any accumulated static charge on your body and preventing that discharge from being sent to or through any electronic component.
Uninsulated dangerous voltage are inside the enclosure, voltage that may be sufficient to constitute a risk of shock. Always disconnect to AC Mains before removing the top cover

9.1 THE INTERNAL CLOCK
Equipment internal Clock is powered by a SuperCAP (capacitor) instead of a traditional battery. The capacitor keeps the clock operating and protects the system memory to prevent the loss of stored programs during power failure around one week long (depending on the environmental conditions).
Capacity charge needs at least 30’ of normal operation. RDS parameters and relevant settings are stored on a non-volatile memory (in order to save data integrity even in the event the coder is not used for long periods).
Clock tolerance might amount to about 1 sec per day (it strictly depends on environment conditions). In the event the SuperCap gets completely discharged, the clock will stop and You will always need to synchronize it
again to the Pc clock using the Axel Tiger Shark Remoter /General Settings window).
Scheduler tool for RDS services stops when internal clock is freezing.

11 FRONT PANEL OPERATION
As already mentioned, the user interface consists of a front panel-mounted jog-wheel, two buttons and an LCD screen. The LCD screen displays menus, parameter settings and several bargraphs (Level Meters or processing activity).
The menus are used for the processing parameters adjustment.
Rotating the jog-wheel lets you browse up or down through menus and parameter choices. Pressing the jog-wheel (called “clicking”) selects the blinking menu item or parameter choice. When editing the
parameter values, rotating the jog-wheel adjusts the parameter’s value up (by rotating CW) or down (CCW). Once the desired value is reached, clicking the jog-wheel twice saves the value and returns the display to the upper
menu level. You can return to the upper menu without saving by pressing the Quit key or by choosing the ‘quit’ option. Thus pressing (or clicking) the jog-wheel serves, depending upon the LCD screen status, as an Enter, Select or Return
command. Please note that when a new value is only displayed – even blinking – it is immediately loaded into the equipment
processing so that the user can get a real time response.
Enter function is achieved by pressing ‘Enter’ button, too. Quit/Return function is achieved by pressing ‘Quit’ button, too.
It is useful to remark that you can access all the menu settings and parameters also in a faster and more comfortable way trough the supplied PC control software (Tiger Shark Remoter), which allows an easy and effective remote monitoring and control, too. When the Tiger Shark control is taken by the PC application in a bidirectional mode (see
Chapter 10), any access to the menu via the front panel keys is not allowed and the message “Remote Pc Host in Control” is displayed.
NOTE: The front panel menu allows only RDS signal level and phase setting. RDS messages programming and all the other related facilities requires the supplied Pc control software – see Chapter 14.
Any access to the Tiger Shark menu via the front panel keys can be blocked.
11.1 THE MENU TREE
The menu tree is shown on the next pages. It has all twelve of the possible main menu items listed along the left side. The branching sub-menus and parameters are connected in the order they are encountered in the menu system.
Note: each version has its own Menu Tree specific to that model. Yr current version might therefore do not show all the items above described. The diagram here above displays the complete Tiger Shark menu – please refer to the
table on Introduction chapter for Optional feature list.
To save the changes, firstly press Enter to get the Save function and then a second time to confirm Press Quit to escape the menu without saving and get the upper menu level Press Quit to get the upper menu level.

12 SUMMARY OF AVAILABLE CONNECTIONS FOR CONTROL
13 INSTALLATION AND USE OF PC CONTROL SOFTWARE
13.1 INTRODUCTION
The Tiger Shark Remoter is a powerful and reliable software running on Microsoft Windows 2000 Professional and XP, Vista, Seven platforms and specially conceived for equipment remote/direct programming and control.
The Tiger Shark Remoter software comes with the equipment. It allows the setting of every parameter and level by means of Bidirectional (i.e. local) serial links or Monodirectional (one-way) serial links. There is no limit in the number of units which can be controlled from a single software license.
The bidirectional (or local) mode allows either the visualization in real time of the equipment current configuration or its modification. This modality is very useful every time you need a real time direct and complete equipment control. A serial bidirectional Pc-target connection is needed.
The monodirectional connection mode doesn’t involve any return channel. It is possible to send commands to the equipment from remote sites, but it is not possible to have neither a remote monitoring of the machine, nor a confirmation of reception of controls. The unidirectional connection mode is used to control one or more units from a remote site, for example over a satellite link.
In this case, it will be possible only to send the commands or new values for operating parameters one way, without the ability to check whether the change has taken place or to monitor the target current status. A typical application is centralized remote control of coders installed at a scattered array of transmitting sites.
The Send button shown in each window allows you to send to the Tiger Shark the changes, once you have configured them on the software screen.

13.2 SOFTWARE INSTALLATION PROCEDURE
MAKE SURE A TIGER-SHARK REMOTER PROGRAM IS NOT ALREADY INSTALLED on Your computer. Uninstall OLDER versions before installing NEW ones. From release 5.8.0 it is possible to use the same Axel
Tiger Shark Remoter with different release.
When upgrading the firmware, do not forget to install the new associated software version of PC remote control. There is a direct correspondence between the firmware and software versions.
For example, the rel. 3.0 of Pc software requires the firmware version 3.0 installed on the unit and vice versa. More precisely, the two first digits must match, as possible sub-releases (identified by the third digit) are not involved in the firmware/software compatibility.
As general rule, software version X.Y.Z runs with firmware version X.Y.K
TIGER-SHARK REMOTER software runs on Windows 2000 Professional, Windows XP, Vista, Seven operating
systems.
TIGER-SHARK REMOTER software runs on operative System that get a Monitor resolution fixed of 96 dpi (as default) and need some System font like: MS Serif, MS Sans Serif, Courier New, Small Fonts. All that needing are for reading correctly the single elements in the software.
IF some condition are not allowed a warning is showed by the Tiger Shark Remoter
In Windows Xp that problem can be solved saving screen settings in Start -> Settings -> Control Panel -> Screen
-> Settings -> Advanced (new window) -> General -> DPI Settings and set as “Normal 96Dpi”

34
14 BASIC CONNECTION TO A SINGLE CODER (DIRECT LINK)
The Direct Link is the most immediate and easy way to connect the Tiger Shark to the Host Pc. It requires a bi-directional communication channel between the Host Pc and the Tiger Shark coder. That channel may be TCP/IP, SERIAL RS 232C type or via MODEM.
This is for a real time monitoring of Tiger Shark current status (audio levels, RDS services, etc).
click Direct Link button
click Open Panel: You will get a mask with a menu
listing all the available Tiger Shark versions. From the Target Type menu, choose the specific
Tiger Shark version You are connecting to (Tiger Shark RDS, Tiger Shark MPX/LIM/RDS)
Make sure the current version of the real Tiger Shark unit You are connecting to matches the selected one
in the Target Type menu. If it doesn’t match,
connection will not be achieved.
Click Work Mode button. At this moment, a very basic connection ‘tree’ will be displayed, showing just Yr Pc (local
Host), the serial communication channel (ComChannel 1) and the target equipment (yr current version of Tiger Shark). For example, the picture shows a Pc connected to a Tiger Shark version MPX+LIM+RDS through a generic Communication Channel named ‘ComChannel 1’.
To check or set-up connection parameters, click ComChannel icon: You will get a window summarizing all settings done / possible for that channel.
Three communication channel may be used: SERIAL RS232, TCP/IP or DIAL-UP MODEM. For settings of each of them, refer to following chapters.

14.1 DIRECT LINK THROUGH SERIAL RS232
Whenever connection to the Tiger Shark is achieved through Serial connection, choose
LOCAL RS 232 in the communication channel configuration windows (ComChannel). Connection mode (‘Link Mode’) will be automatically set as ‘bidirectional’:
You will need to set parameters associated to the Pc Serial Port to be used and to its speed.
SERIAL PORT
It selects the Pc Serial Port to be used for the connection (from 1 to 255).
SERIAL SPEED
It sets the maximum Baud Rate for the selected Pc port. By default, the Tiger Shark Remoter will show the maximum value (38400 Baud)
The communication Baud Rate set on the Pc Control Software MUST MATCH the corresponding Baud Rate set for the linked Serial Port on the Tiger Shark For example, if Serial Port 1 on the Tiger Shark runs at 4800 Baud, the same speed must be set also for the Pc Serial Port involved in the link.
Enter a mnemonic comment / character string into the ‘User Note’ field (For example: TELECOM TOWER – Radio One). Click OK to confirm, ESC to leave without saving.
14.2 DIRECT LINK THROUGH UP-LINK MODEM
Whenever connection to the Tiger Shark is achieved through two Dial-Up modems,
choose ‘MODEM’ in the communication channel configuration windows (ComChannel). Connection mode (‘Link Mode’) will be automatically set as ‘bidirectional’:
Refer to the APPENDIX of this manual for physical connection between the Modem and
the Tiger Shark , at the Remote side (Tiger Shark Serial Port 1 must be used for that purpose). On the Tiger Shark Remoter software, You must set the Serial Port used for connection to the modem and associated connection speed (that usually is 38400 Baud for Pots/PSTN modems and 9600 Baud for GSM modems). You are also requested to enter a Modem initialization string.
SERIAL PORT
It selects the Pc Serial Port to be used for the connection (from 1 to 255). In the event of an USB modem, check which ‘virtual’ Serial port is automatically selected by the Pc.
SERIAL SPEED
It sets the maximum Baud Rate for the selected Pc port. By default, the Tiger Shark Remoter will show the maximum value (38400 Baud),
The communication Baud Rate set on the Pc Control Software MUST MATCH the connected Modem Baud Rate.
INIT STRING
Enter here the modem AT initialization string. The Tiger Shark Remoter offers two pre-set strings. The shortest one (at&f&k0&c0&r1s2=255) usually fits PCI internal modems, while the longest one (at&f0&k0&c0&s0&r1s2=255) usually fits external modems.
PHONE NUMBER
Enter here the number to dial, along with Country code, Area Code, Prefix, etc.
Click OK to confirm, ESC to leave without saving.

14.3 CONNECTING A DIAL-UP MODEM
Whenever a remote control through dial-up modem is required, connect the modem to Serial Port 1, on the back of the unit. Please pay attention to the Port 1 configuration: its speed must be set to:
- 38400 Baud for Pots dial-up modems
- 9600 Baud for GSM modems.
A ‘cross’ (NULL-MODEM) CABLE is needed for connection to the modem. The following table shows the wiring diagram for the cable in both case the Modem has 9 pins or 25 Pins female SubD connectors.
Also remember to:
On a 25 pin plug connect pin 6 and 8. On a 9 pin plug connect pin 1 and 6.

Regarding the Receiving Modem (the one connected to the Shark serial port), it must have at least the following settings (modem commands are in brackets. They are related to the most common modem models):
- IGNORE CD (the usual command is &C0)
- IGNORE RTS (&R1)
- IGNORE DTR (&D0)
- Disable TX Flow Control (&H0)
- Disable RX Flow Control (&I0)
- Disable Data Compression (&K0)
You also to set the S0 and the S2 registers in the following way:
- S0=2
- S2=255
ENG
Axel Technology srl www.axeltechnology.com | BASIC CONNECTION TO A SINGLE CODER (DIRECT
LINK)
37
S0 Register represents the number of rings before Auto-Answer. It sets the number of the rings required before the modem automatically answers a call. Range: 0-255 rings. Setting this register to zero disables auto-answer mode. S0 = n, where n is the number of rings. It is advised S0=2
The S2 register (Escape Code Character) specifies the ASCII value of the character used in the escape code. (The escape code is the escape character entered three times in succession.) When the modem is in connect state and it receives the escape code, the modem enters command state. Normally, setting register S2 to 128 or above disables the escape code character. It is advised to set S2=255
You should load those settings in the modem memory, so that they are automatically loaded at the modem start-up. Please refer to the modem user guide for further reference.
For proper configuration of Tiger Shark Remoter software in order to support modem communication refer to Part TWO of this manual.
14.4 DIRECT LINK THROUGH TCP/IP
Make sure the Tiger Shark already has a valid TCP/Ip address with relevant subnet mask and IP Port Number (see next Chapter for further help).
Choose ‘TCP/IP’ in the communication channel configuration windows (ComChannel).
You will get a mask summarizing data of current TCP/IP connection:
To enter the actual IP address and IP port of the Tiger Shark to connect to, click [EDIT]. The ‘Configuration Editor’ program will open. Refer to relevant Chapter for using the Editor.
Click button. The Configuration Editor screen will load the Data Base of existing Tcp/Ip connections and will list them. In particular, in the section [GROUP_START], the Editor gives the possibility to enter a ‘mnemonic’ name for the Group one is connecting to, plus a name for the specific unit in the Group, its IP address and associated Port.

20 MANAGING TIGER-SHARK in GROUPS
Tiger Shark Coders can be managed / accessed either as single Units, or in groups. To manage Tiger Shark in Groups, You will need to assign each unit with a identification code, composed by a Device Number and a Group Number.
This give the users the highest flexibility in controlling units individually or in groups, by sharing same commands among several units or forcing an individual unit with a specific address to execute a broadcast command.
The Device Number and the Group Name will be given to each Tiger Shark using a dedicated tool, called Target Edit Manager and included in the Tiger Shark Remoter – software suite.
The same tool allows also to provide each individual unit or group with a ‘Target / Group Name’, i.e. a ‘mnemonic’ field to
make control and connection much easier. For example, a national network could assign the Group Name field to the region where the unit is in operation, and give
the Target name the name of the town hosting the broadcasting site, or the city covered by that site. Suppose you have 3 coders in the Tuscany region (the first covers Lucca, the second Florence and the third Pisa) and 4 others in the Marche (Pesaro, Ancona, Urbino, Macerata). The Target name and Group Name will be programmed for the individual machines as follows: Group name = Tuscany, Target Name = Lucca for the first coder, Group name = Tuscany, Target Name = Florence for the second coder, etc.

Connection between remote Tiger Shark units and the central control Pc may be uni-directional or bi-directional, depending on the available communication resources and the typology of controlled units. For example, the picture above shows a Satellite channel, which is typically uni-directional, two serial RS232 connections, one monodirectional (because connecting a group of equipment) and one bi-directional (linking just one unit). Up to 5 Users can be managed, each one accessing its own system tree, i.e. its own portion of system. That means, it is possible to give to each user different rights in accessing the targets and their configuration.
Group Number and Device Number correspond respectively to UECP Site Address and Encoder Address codes
20.1 FIRST STEP: COMPOSE THE ‘TREE’ INTO THE TIGERSHARK REMOTE (EDIT
MODE).
As first step, You need to ‘edit’ (draw) the system tree like on a ‘blackboard’, starting from the central Control Pc, adding connection channels and, for each ‘branch’, the associated target(s) or groups of units.
Local Host Pc is the Pc running the Tiger Shark Remoter software (i.e. the Pc you are using!). At this time, each single
element composing the system will be not configured. We just place ‘blocks’ onto a virtual ‘blackboard’, to have a proper
representation of the actual system. Later, from the Work Mode, each unit will be assigned with ‘real’ operation parameters, such as Baud Rate, Com Ports, Address, etc.
You may edit / compose 5 different system trees, one for each USER listed in the Tiger Shark Remoter panel (USER 0, USER 1, USER 2, USER 3, USER 4).
1
Select the User access (for example. User 0) and then press the Open Panel’ button: the User navigation Panel will be automatically displayed.
2
LOCK function: To prevent undesiderable access to
system configuration pages, enter a generic password
(which can be changed at user’s discretion) in the
blank field and click Lock button. To unlock, enter the SAME password and click ‘unlock’
Click Edit Mode button: Edit Mode Navigator Panel will
open ( and the ‘Edit Mode’ identificator appears at the
upper right corner).
3
Move the mouse pointer onto the Pc LocalHost icon and then click right: a
pop-up menu will appear. First, You have to add a Com Channel,
i.e. a serial link connecting the Control Pc to remote target(s). That Com Channel will be edited later.
Each Com Channel may be associated to Single Units (single targets) or Groups of Targets. Various ‘undo’ tools are also available for removal of inserted elements or system re-initialization.

20.1.1 ADDITION OF A SINGLE CODER
Having placed the communication channel, click right on ComChannel icon: a new pop-up menu will appear. To add a new single encoder, select Add New Encoder item and then select the Target version (MPX, RDS, etc)
Every time a new Target or a new Group of Target is added, a special window (Target Edit Manager) opens automatically.
It allows You to set two basic Target identification codes: a Device Number (4 characters) and a Group Number (2 characters). It permits also to associate an identification label (Target Name) which makes target identification easier across the network. The Target Name will be displayed next to the icon on the System Tree, as well as in the ‘Settings’ window in
the Tiger Shark Remoter. Please refer to paragraph “THE MNEMONIC IDENTIFIERS FOR SINGLE TARGETS
OR GROUPS”.
Be careful not to assign the same Target name or the same Group name to two different devices.
Group Number and Device Number correspond respectively to UECP Site Address and Encoder Address codes.

20.1.2 ADDITION OF A GROUP OF CODERS
After having created a new communication channel icon (see ComChannel2 in the picture), click right on that icon: a new pop-up menu will appear. To add a group of encoders, select Add New Encoder Group item and then select the coder type. A new group of encoder is a group of Targets which share the same Group number and are of the same type (i.e. they can be programmed in the same way and at the same time).
NOTE: Communication channel is automatically forced to Monodirectional (one-way) as soon as two or more
‘targets’ will share the same communication channel i.e. as soon as a New Encoder Group is added.
The ‘Group Edit Manager’ window will open automatically. It can:
Assign a specific Group identifier (Group ID) or associate current
targets to all Groups (ALL)
Assign a Group Name, i.e. a mnemonic identifier (max 20
characters).
State which configuration commands (MPX settings, Audio
Control, RDS Settings) will be accepted by this Group (i.e. which configuration can be altered from the remote side). As You can easily understand, available command configurations will depend on actual version of Tiger Sharks belonging to the Group.
In the event of RDS versions, the window will list those services
which can be altered from remote (DI, PS, RT, etc).
SET ALL button sets all available services ‘on’ CLEAR ALL button set all active settings ‘off’.
Once the window has been edited, press Confirm to save data or ESC to quit without saving modifications.
The Group Edit Manager’ window can be recalled at any moment just
double-clicking on the associated Group icon.
Group Number and Device Number correspond respectively to UECP Site Address and Encoder Address codes.

20.1.3 THE MNEMONIC IDENTIFIERS FOR SINGLE TARGETS OR GROUPS
The fields ‘Target Name’ and ‘Group Name’ in the respective Target Edit Manager and Group Edit Manager windows may be loaded with a name or an equipment label (max 20 characters) in order to make coder identification easier. Typically, identifiers are geographic identifiers or they are associated to the name of the Network or to the Frequency/channel used.
For example, entering ‘New York – TV tower’ as
Target Name, that name will appear next to the device (see picture on the left).
The same name will appear in the ‘General Settings’ window / ‘Encoder Data’ field and in the connection
summarizing table of the Tiger Shark Remoter (see picture below), once the link with the target has been
established.
NOTE: ‘Target Name’ and ‘Group Name’ are saved on the computer running the Tiger Shark Remoter. They are never installed into Tiger Shark physical memory. They serve as ‘guide’ / hint for the connection task

Follow the same procedures shown in the ‘BASIC CONNECTION TO A SINGLE CODER’ for proper configuration
of connection channels and targets.
20.3 CONFIGURATION OF A MONO-DIRECTIONAL COM CHANNEL
As already stated, a system composed by a single Pc at the head of the network and by several distant Tiger Shark units (Targets) may require mono-directional com channels, i.e. channels which do not support any data stream from the Target back to the central control Pc. Monodirectional Com channels are usually available over satellite links. In general, a Mono-directional channel may be RS-232 or Modem type. In both cases, You will need to configure which Serial Port and which speed must be used.
SERIAL PORT
It selects the Pc Serial Port to be used for the connection (from 1 to 255). In the event of an USB modem, check which ‘virtual’ Serial port is automatically selected by the Pc.
SERIAL SPEED
It sets the maximum Baud Rate for the selected Pc port. By default, the Tiger Shark Remoter will show the maximum value (38400 Baud),
The communication Baud Rate set on the Pc Control Software MUST MATCH the corresponding Baud Rate set for the linked Serial Port on the Tiger Shark. For example, if Serial Port 1 on the Tiger Shark runs at 4800 Baud, the same speed must be set also for the Pc Serial Port involved in the link.
In addition to connection speed, also a
‘packet redundancy’ factor may be set, in
order to increase robustness of the link against transmission errors.
In practice, no packet redundancy means
each transmitted racket contains ‘original’
information, not duplicated.
One packet redundancy means each data packet is followed by a second packet bearing the same information. If the first packet gets corrupted, the second is used to recover original transmitted information.
With the same philosophy, Two packets Redundancy means each data packet is followed by two redundant packets; Three packets Redundancy means each data packet is followed by three redundant packets, etc.
As one may easily understand, maximum link reliability is achieved by setting Four Packet Redundancy, even if it involves a ‘real’ (payload) connection speed which is one fifth of that selected in the ‘Serial Speed’ menu.

21 THE ‘CONFIGURATION EDITOR’: WHAT IS AND HOW TO USE IT
The Configuration Editor makes viewing or changing the Tiger Shark current settings easier, as it allows you to edit a configuration file, through an easy-to-use TEXT ONLY interface like Windows "Notepad".
Complicated system parameter settings / changes can be simply accomplished in a ‘written’ mode, through
commands/values provided in a textual (ASCII) way. For example, a simple PSN programming may be ‘written’ as follows:
PSNAME_0= "BBC ONE ",Normal PSNAME_1= "LONDON ",Normal PSNAME_2= "UK ",Normal
Furthermore, any operative configuration of the encoder (input gain, pilot level, RDS messages, RDS DataSet status, etc) may be saved at any time and recalled at Yr convenience.
You may also ‘Import’ (download) the current configuration from Your target and:
duplicate it on a new Target print-out it in a textual (ASCII) format save it in a Pc directory
The Editor can run in two different modes: off-line (i.e. there is no direct link to the encoder) or on-line (i.e. the computer running the Tiger Shark Remoter Remote Software must be communicating with the Tiger Shark).
In the Off-Line mode, You may open one of the ‘Demo’ files or edit a file previously saved. Edited files can NOT be loaded into Tiger Shark memory.
In the ON-LINE mode, with a bi-directional link You may import from the Target its current configuration, edit it and then export it again to the Target. Using a mono-directional link export toward the Target will be only achievable.
The Configuration Editor is based on standard Windows tools for text editing (copy, paste, cut, find, undo, save, open, etc) and its us is therefore simple and intuitive.
To open the Configuration Editor in the ON-LINE mode: after accessing the target in Simple or User X mode, click right on the Target icon on the Navigation tree.
In the OFF-LINE mode click on Open Configuration Editor in the Connection Manager window before connecting to the Target.
A Warning box will remind You that You have chosen the off- line work mode. As the Target is not connected, Import / Export of current Target configuration are therefore not possible.
Click OK to access next Configuration Editor window.

21.2 TYPICAL IMPORT / EXPORT TASKS
As explained, Configuration Editor allows You to import (download) current configuration from the Target in order to easily edit/modify it. Once the editing task is accomplished, the new configuration file can be easily exported to the file in order to make it effective.
This is the procedure to follow.
- With the Target connected in Bi-directional mode, click the IMPORT icon : data transfer from the Target to the computer will be engaged. This could take from a few seconds to a few minutes, depending on the link speed.
- Once the import has finished, the Configuration Editor window will display the current, full Tiger Shark configuration, starting from ‘hardware’ data (in/out levels, selected audio input, etc) and then showing RDS data for each DataSet. Keys DS1, DS2, DS3 and DSA (DataSet Alternative) give direct access to configuration data of associated DataSet.
- De-select the ‘Read Only Mode’ option
Every time a new file is loaded, it is displayed in ReadOnly mode, in order to prevent from accidental modifications. Uncheck ReadOnly box prior to start editing the file.
- Edit the file using the provided tools. Pay particular attention to text layout (spaces, punctuation, etc).
- Once finished editing the text, click TEST tool (magnifying glass ) to check correct text formatting: in the event of syntax or typewriting errors, relevant text line will be automatically highlighted in bold. Appendix A contains full syntax of the Configuration Editor.
Click EXPORT button : the edited configuration file will be automatically transferred to the Target. When file
transferring ends, Tiger Shark will be on-line again, according to new configuration loaded.
EXAMPLE
To Increase MPX output level to +5.6 dB (default is 0.0 dB) follow these steps:
With the Target connected, click IMPORT icon Wait for file loading
Go to [MPX_SETTINGS] section:
MPX_LEVEL=+0.0dBm PILOT_LEVEL=-19.8dB PILOT_PHASE=+0Deg POST_CLIPPER_GAIN=+0.0dB
Deselect the ‘Read Only Mode’ option
Type the new MPX output level:
MPX_LEVEL=+5.6dBm
Click TEST icon to check data consistency
Click EXPORT icon
In the meantime, the same configuration file my be saved (for example to load into another Target) by pressing icon
The same file can be also printed-out
Close the Configuration Editor window (Exit)

21.3 EXPORTING ONLY SECTIONS OF A CONFIGURATION
The Tiger Shark Configuration file is composed by several sections, each of them ending with an ‘End Point’ marker. You may export to the Tiger Shark only one of more sections instead of the entire file, in order to preserve some crucial
operating parameters from tampering or risk of overwriting.
In other words, when clicking ‘IMPORT’ button, always the full configuration is downloaded but, when exporting back into
the Tiger Shark, You may exclude from transferring one or ore sections, thus forcing the Tiger Shark to operate on the basis of data already in its memory.
For example, in case of a Tiger Shark version LIM+MPX+RDS, You may prevent to export the entire section associated with ‘hardware’ settings (input adjustment, pilot level, etc) with the exception of the first 3 lines (see here below) and update the Tiger Shark only for the 4 DataSets.
As explained in Appendix A, the first three lines MUST be always present in a configuration file:
TARGET_MODEL={ Tiger Shark_Rds , Tiger Shark_Mpx, Tiger Shark_Mpx/Rds, Tiger Shark_Mpx/Lim , Tiger Shark_Mpx/Lim/Rds, Tiger Shark_Rds_Group , Tiger Shark_Mpx_Group , Tiger Shark_Mpx/Rds_Group , Tiger Shark_Mpx/Lim_Group , Tiger Shark_Mpx/Rds/Lim_Group }
FIRMWARE_VERSION={ 5.2.0 } TARGET_NAME="Nome Target " (this name is ignored by the Target)
Concerning the remaining part of the file, You may omit all lines following [END_+ SECTIONNAME] identifier Also Data Sets may be removed from the Configuration File, beginning from those of major index (for example, You may
export DS1, DS2 and DS3 only, or DS1 and DS2 only, etc).
Tiger Shark presents the following default settings:
IP Address
192.168.000.020
Subnet Mask
255.255.255.000
IP Port
1327
Enter new settings in the relevant fields. For example, the picture above shows Tiger Shark programming with address
192.168.0.64, SubNet Mask 255.255.255.0 and Port 1336. Click SEND DATA to up-load new settings into Tiger Shark memory.
Before disconnecting from the Target, it is advisable to check integrity and consistency of loaded data using the ‘Reload
Data’ function, which access the Tiger Shark memory and shows its actual content. Once the task is finished, click ‘Quit’ .
At every IP data change (address, Subnet Mask, Port), You will must wait 15 seconds before the new configuration becomes operative.
Whenever turning off/on the Tiger Shark, You must wait 15 seconds before the LAN board starts-up and becomes visible on the network.
You may always check current IP settings from the front panel menu on the Tiger Shark (SYSTEM INFORMATION, submenu Tcp/Ip Address, Tcp/Ip Port and Tcp/Ip S.Mask).
NOTE: refer to UECP normative for the use of ID List and Group List fields.

23.1 THE MPX SPECTRUM
We assume MPX signal is composed by three major components:
audio signal (L and R channels)
pilot tone (19Khz)
RDS signal (57Khz)
The stereo encoding process modulates (double side-band suppressed carrier) the L-R or stereo difference signal onto a 38kHz sub carrier. Its side-bands will extend by +/- 15kHz. At the top end this will be 53kHz. Digital filter accomplishes all contents above 53 kHz are suppressed by the highest level. This precise spectral management contributes to loudness, since it ensures that no wasted energy is transmitted.
Please note that composite clipper does not degrade RDS signal quality because it is applied before the 19kHz pilot is added to the multiplex signal (if the pilot was present at the composite clipping stage, the third harmonic of the pilot caused by the clipping process will fall exactly on 57kHz, degrading the RDS).
Each component of MPX signal is generated digitally and therefore available at the highest quality.

23.2 AVAILABLE INPUTS
The Tiger Shark manages 4 input sources:
a stereo analog audio pair a stereo digital audio pair an input for external MPX an Mp3 Player on SD Card (optional)
NOTE: Mp3 Player replaces, according to user requirements, either the analog input or the digital input, according to Jumper J9, J10, J11 position on the audio input card.
Selection between sources may be achieved
manually, automatically, by internal changeover stage and silence detectors or by contact closure (GPI input).

23.4 HOW TO SELECT THE INPUT SOURCE
In the General Settings panel of the Pc Control software, You may
select the (primary) source for the Tiger Shark stereo coder:
analog audio (stereo input) digital audio (AES/EBU input) MPX = pass-through of an external Auxiliary MPX signal (by factory
default connected to AUX-1 input).
In the event of digital sources, you are also required to set audio source resolution (16 or 24 bits / sample). Primary input audio source selection may be achieved also from:
Front panel menu Web server (General Settings page)
23.5 HOW TO TURN THE AUTOMATIC INPUT CHANGEOVER ON / OFF
TURNING OFF THE AUTOMATIC INPUT CHANGEOVER STAGE
To prevent the Tiger Shark from automatically switch over a back-up source in the event of fault of Primary source (by silence detection), set ‘Secondary Input’ drop-down menu in the Audio Control page to OFF.
TURNING ON THE AUTOMATIC INPUT CHANGEOVER STAGE
To get automatic switch over an alternative source, select the alternative (secondary) source from the ‘Secondary Input’ drop-down menu in the Audio Control page.
MPX stands for ‘Auxiliary MPX input (usually factory-associated to Aux-1 input)
You also need to enable audio changeover from the Audio Input Mask in the Audio Control page.
Make sure: Force Secondary Input from General Purpose Input 1’ in the MPX page is NOT ticked.

DESCRIPTION
Check for Auxiliary Mpx Deviation
Changeover stage checks deviation of external MPX applied by default to Aux-1 input. Input signal is considered as not valid if deviation exceeds 80 kHz for repeated times.
Check for Audio Presence in Auxiliary Mpx
Changeover stage checks presence of audio part (Main + SUB) in the external MPX applied by default to Aux-1 input. Input signal is considered as not valid if audio part is lost.
Check for Pilot Presence in Auxiliary Mpx
Changeover stage checks presence of Pilot in the external MPX applied by default to Aux-1 input. Input signal is considered as not valid if Pilot is not present.
Check for RDS Presence and specific PI in Auxiliary Mpx
Changeover stage checks presence of RDS modulation in the external MPX applied by default to Aux-1 input. Input signal is considered as not valid if RDS is not present. Furthermore, if the PI box contains a valid PI (Program Identifier) code, Tiger Shark verifies that source PI equals PI stated in the box. If not, the source MPX signal is considered not valid. NOTE: to disable PI check, leave PI code = 0000.

24.1 INPUT AUDIO LEVEL CONTROL
Input level control stage is actually based on two sub-controls: sensitivity adjustment and ‘fine’ tuning, independent for channels Left and Right.
Right Gain (applies to either analog or digital sources). It may adjusted in + /- 12 dB range with 0.1 dB step. Default: 0 dB.
Left Gain (applies to either analog or digital sources). It may adjusted in + /- 12 dB range with 0.1 dB step. Default: 0 dB.
Sensitivity: different for analog and digital sources, it may adjusted in 0.1 dB steps. Analog: + 15 dBm to – 9 dBm. Digital: from 0.0 dBfs to – 24.0 dBfs.
Two buttons allows to Return automatically to Zero (RTZ) level on Input L/R Gains.
Input gains controls are automatically disabled when automatic Working Modes are engaged (Clipper MPX and LogClipper)–see next paragraphs.
24.2 SETTING THE OUTPUT PRE-EMPHASIS
(MPX panel / Preemphasis): it may be set to Off, 50uSec (as in use in European countries), 75uSec.
NOTE: Only one pre-emphasis must be kept active in the transmitting chain. It is advisable to turn OFF the Tiger Shark pre-emphasis and enable the pre-emphasis generated by the audio processor. This because a pre-emphasis filter applied at the last
step of an audio chain emphasizes ‘payload’ signal along with possible noise, thus resulting
in a degraded performance of the whole system.
It is advisable to set the right Pre-emphasis as first step, as it affects the MPX generated level and thus the whole level tuning process described in these pages.

24.3 SUMMARY OF AVAILABLE AUDIO WORKING MODES
24.3.1 INTRODUCTION
6 automatic modes plus 3 manual working modes are available. In automatic modes, Tiger Shark automatically adjusts audio input levels (L/R gains) and AGC level in order to ‘size’ the
portion of audio signal clipped by MPX Clipper (see ‘A’ amplitude portion in the picture here below, exceeding clipper trimming amplitude) and thus get control over resultant density of aired MPX signal. 3 modes (Safe, Normal or Aggressive) are available.
Clipper threshold applied to input signal. Depending on the chosen Clipper mode,
a variable portion of the signal will be cut-out by the clipper, resulting in an increased density.
In addition to a ‘brutal’ cut, user may choose 3 alternative clipping modes, described as ‘LogClipper’ modes, which
perform a smoother clipping factor following a logarithmic curve. LogClipper modes also may be set as Safe, Normal or Aggressive clipping modes, depending on the kind of desired clipping mode.
3 manual clipping modes are available (2 with no Clipper intervention, one with Clipper intervention). By choosing one
of those modes, Tiger Shark behaviour is identical to a traditional, non-automatic Stereo Generator. Input Gain controls are in these cases fully user-adjustable.
CLIPPING VS LIMITING
In addition to Clipping, THE Tiger Shark features a built-in audio limiter. While deviation overshoots are cut-out by MPX Clipper, fast changes in the input audio levels are ‘normalized’ by the Limiter stage, thus concurring to keep as much constant as possible the audio level at the MPX Clipper input. Typically, Limiter stage is proven helpful in presence of quick ‘jumps’ in input levels, such as those occuring when switching between different studios, when switching from normal audio program to Advertisement spots, etc).
2 Limiter modes are available: eee next chapter for further reference.

Linear Full Range
Manual
Tiger Shark’ behaviour is totally similar to that of an analog,
traditional stereo encoder. There is no MPX clipper intervention. There is no deviation limit. Input headroom is around 20 dB. All signal components (including filter overshoots) will contribute for the final deviation on-air.
Main signal deviation (and therefore signal ‘loudness’) will
be therefore significantly lower than by using a well-tuned Clipper.

MPX Clipper
SAFE
Auto
AGC stage is engaged and input levels are automatically adjusted, in order that only very small peaks (0.2 or 0.3 dB of amplitude) will cross the clipper threshold and they will therefore cut-off by the MPX clipper itself. This mode preserves in the highest degree original audio program.
MPX Clipper
NORMAL
Auto
AGC stage is engaged and input levels are automatically adjusted, in order that only medium peaks (0.7 or 0.8 of amplitude) will cross the clipper threshold and they will therefore cut-off by the MPX clipper itself. This will result in
an increased ‘mean’ volume, even if a slight distortion could appear with a ‘out-of-band’ energy.
MPX Clipper AGGRESSIVE
Auto
AGC stage is engaged and input levels are automatically adjusted, in order that large peaks (1.2 or 1.3 dB of amplitude) will cross the clipper threshold and they will therefore cut-off by the clipper itself. This will result in an increased density, even if distortion could appear with a consistent ‘out-of-band’ energy.

24.4 HOW TO ADJUST THE INPUT GAIN ON MANUAL WORK MODES
This section should be performed for both the analog and digital audio inputs. The Tiger Shark will store level settings for each separately allowing to switch between analog and AES/EBU inputs without resetting the input level. Note that there are different controls for calibrating digital versus analog audio inputs.
BEFORE CALIBRATION, MAKE SURE YOU HAVE PREEMPHASIS SET TO THE APPROPRIATE TIME FOR YOUR APPLICATION AS THIS WILL AFFECT THE OUTPUT LEVEL.
At this moment, Warning LED on the front panel might flash due to Audio Input overload and/or MPX signal exceeding deviation limit. Proper overall Clipper stage tuning coincides with Warning LED turning off. Therefore Audio input calibration might be not able to accomplish this condition.

24.4.1 LINEAR MODE
With a 0 dB MPX level, Nominal Input Level reference indicates the input audio level (peak level) which corresponds to 75 kHz deviation. Sensibility and Gain controls should be adjusted so that the input program peak level coincides with the 100% modulation ‘ceiling’.
Note: Setup should be performed for both the analog and digital audio inputs. The Tiger Shark will store your level settings for each input
separately allowing you to switch between analog and AES/EBU inputs without resetting the input level. Note that there are different controls for calibrating digital versus analog audio inputs.
The Sensitivity Level (Analog or Digital) parameter sets the gain for both channels. After adjustment, peak indication
hitting the Nominal Input reference point on the display or a little higher (see picture here below) is proper. This corresponds to 10 dB system headroom.
If further gain or attenuation is required, the individual left/ right Gains can be adjusting using the Input Left and
Input Right controls
An optimal calibration of Left/Right input levels is displayed here- below.
Be aware that well-defined audio peaks are achieved only with processed audio signals. Otherwise, no precise calibration of input signal will be possible.
After digital or analog input calibrating, You may set the analog level of the composite signal on the BNC connector. Please adjust the Post Gain + MPX level controls until you reach the desired modulation level.

24.4.2 LINEAR – FULL RANGE
If a better headroom / input dynamic range (than the Linear Mode) is required, LINEAR-FULL RANGE input mode is provided. No clipping and no deviation limit is applied to signal processing in this case. Input headroom ranges up to 20 dB and an overall MPX level control is not provided. Nominal input level reference is nearer to the left margin than in the Linear Mode – MANUAL .
Note: Setup should be performed for both the analog and digital audio inputs. The Tiger Shark will store your level settings for each input separately allowing you to switch between analog and AES/EBU inputs without resetting the input level. Note that there are different controls for calibrating digital versus analog audio inputs.
1) The Sensitivity Level (Analog or Digital) parameter sets the gain for both channels. After adjustment, peak indication hitting the Nominal Input reference point on the display or a little higher (see picture here below) is proper. This corresponds to around 20 dB system headroom.

24.4.3 CLIPPER MODE
Metering scale is divided into three zones.
Linear Zone
This identifies the portion of audio signal that is affected only by Low-Pass / Preemphasis filters. No alteration due to the clipping is introduced. Signal is only affected by input filters and pre-emphasis.
Clipper Zone
This identifies the portion of audio signal being clipped.
Over Zone
This identifies a ‘distortion’ zone, which is related to a ‘out-of-band’ energy. Signal ranging in this zone
should be avoided.
With a signal ranging in the Linear zone, You will need to increase sensitivity or Gain in order to get a signal hitting the Clipper Zone. In the following pages two preferred ways are described: with 100% Modulation Tone and with Processed Audio Signal.
CLIPPER MODE - CALIBRATION THROUGH REFERENCE TONE
1) Apply a Reference Tone (such as the Ref Tone generated by Falcon 15, Falcon 35 and Falcon 50 by Axel Technology) at its maximum level to the Tiger Shark analog or AES/EBU inputs. This will ensure right headroom when using pre-emphasis. The Peak Tone identifies the maximum peak value of the audio and MPX signals reached by the equipment
2) Select the INPUT Module Setup menu and adjust the Sensitivity Level (Analog or Digital) control. After adjustment, peak indication hitting the left margin of Clipper zone is proper (see picture here below). This corresponds to a around 20 dB system headroom.
3) If further gain or attenuation is required, the individual left/ right Gains can be adjusted using the Input Left and Input Right parameters.
Following this calibration procedure, audio material will be kept unaltered and only spurious signal will be clipped.
4) Enable normal audio processing on the audio processor.
Depending on the input level and on the audio material contents, audio peak will range between 1 and 8 segments on the meter reference scale. This peak increase on dynamic conditions is due to overshoot of input digital filter. An overshoot of 3-4 segments (around 1 dB) may be deemed acceptable in case of disabled Tiger Shark preemphasis and an overshoot of 6-7 segments may be deemed acceptable in case of enabled Tiger Shark preemphasis. As practical rule, if the audio peak ranges in the left half of Clipper Zone, possible overshoots will be compensated by Tiger Shark filters.
The following picture displays two acceptable calibrations:
The following picture displays two unacceptable calibrations (please, adjust Gain controls until peak ranges in the left half Clipper Zone):

MODES
72
An audio material which is Preemphasized-only (i.e. not processed) may create very high peaks (over 13 dB). In this case, no accurate modulation control can be accomplished.
CLIPPER MODE - CALIBRATION TROUGH PROCESSED AUDIO MATERIAL
This setup procedure presupposes no reference Tone is available and that Tiger Shark is fed by the output of an audio processor properly adjusted. As explained, this external audio processor must maintain program peaks at a ceiling value corresponding to 100 % modulation. Furthermore, it should add proper pre-emphasis.
Three Clipper calibration modes are possible: Protective, Normal, Aggressive.
Protective Clipper calibration is accomplished when audio peaks hit only the first two segments of the Clipper
Zone. This allows a very ‘clean’ modulation, without any
audible distortion
Normal Clipper calibration is accomplished when audio peaks hit the center point of the Clipper Zone. This allows a good ratio between loudness and distortion
Aggressive Clipper calibration is accomplished when audio peaks hit higher than the middle point of the Clipper Zone. This allows a very loud sound
REMARKS: For a safer modulation, audio peaks should never exceed the Clipper Zone.

24.5 AGC STAGE - SETTINGS AND OPERATIONS
AGC STAGE is active only whenever an automatic working mode (either ‘Clipper’, or ‘LogClipper’) is engaged.
AGC controls are grouped in the Audio Control panel
GATE It sets the intervention AGC threshold. It is rated in dBr, with reference to an audio signal generating a 100 % modulation. Default value is – 6 dBr.
SPEED It sets the AGC action speed. It is rated in dB per second.
MIN GAIN It sets the max reduction factor applied by the AGC stage to the input signal. For example, -3.6 dB means
that the input signal will be reduced by max 3.6 dB.
MAX GAIN It sets the max amplification factor applied by the AGC stage to the input signal. For example, +2.8 dB means that the input signal may be increased by 2.8 dB at the maximum.
AGC MODE In UnLinked mode, the AGC stage acts separately on the Left and Right channel (and thus may compensate for difference in levels between them) while in Linked mode both channels are subject to a unified control.
24.6 STEREO ENHANCER CONFIGURATION
The Stereo Enhancer stage compensates, in a ‘virtual’ mode, for a stereo image partially corrupted or altered by the STL.
There are 4 levels available: Off, Low, Normal and High. It is recommended to set Low or Normal levels if a Stereo Enhancer is already provided
in the audio processor or the link between the audio processor and the Tiger Shark doesn’t alter in a strong way the original signal (for example whenever they are linked by a straightforward audio cable)

25 STEREO GENERATOR - LIMITER STAGE CONFIGURATION
25.1 INTRODUCTION
Even In presence of a well-controlled signal at the output of the audio processor, the STL (satellite link, terrestrial link, ISDN, etc) may introduce errors and distortions which usually appear as undesired peaks (as high as 100 or more KHz of deviation, assuming 75 KHz mean value). Those peaks (also called ‘overshoots’) never carry ‘payload’ information and they are usually cut-off by the clipper. The Limiter stage is recommended to control those extra-threshold components (such as sudden change in the mean audio levels) lasting longer than overshoots.
Each time a signal is clipped, an ‘out-of-band’ noise which affects MPX output is generated. In presence of short, fast peaks, that noise will be not very likely appreciable. But with overshoots lasting for sufficient time, then the Limiter will help in reducing the ‘out-of-band’ energy (small clipping) and keeping the MPX output as ‘clean’ as possible.
Limiter stage and AGC stage act in a different manner. As the AGC response speed is not comparable to the Limiter intervention time, the Limiter is recommended to correct fast input variations, while the AGC performs long-term corrections.

25.2 OPERATING MODES
The LIMITER stage can be engaged at the user’ willing. It comes before the traditional Clipper or Logclipper stages and its benefits are described at the following page. Three LIMITER operating modes are available:
MODE
DESCRIPTION
OFF
The Limiter stage is disengaged
HIGH PROTECTION
Protection is given by combined action of a Limiter and a Compressor stage. Action range for the Limiter stage is around 1 to 1,5 dB. In the event the input signal has a larger level range, the Compressor stage helps reducing input level to the max one compatible with the Limiter stage. This mode privileges audio quality (= low distortion) in respect of increasing output density.
PROS: even in the event the input program is affected by unexpected changes in levels by 3 or 4 dB (such as those occurring in presence of switching between studios, advertisement breaks, etc), there are no distortions on the output.
CONS: output density can not be increased by more than around 1 dB.
LOW PROTECTION
Protection is given by Limiter stage only. Action range for the Limiter stage is around 1 to 1,5 dB. This setting is very effective when dealing with signals exceeding the Clipper threshold by 1 dB max
PROS: output density can be increased with (theorically) any limit CONS: If input signal has variations in its level of more than 1,5 dB, MPX signal density will increase
but with a noticeable distortion degree.
LOOKAHEAD
Tiger Shark introduce a Heavy-Hard limiting, using a predictive mode called “LookAhead”. This special mode allows to achieve the maximum protection over 60kHz-band, and the 19kHz and 57kHz maximum protection. This lookahead introduce a delay of 2ms, bringing the total group delay around 5ms. It is not really suggested if your target is Density and Presence in relation to the total signal quality. With Lookahead the Pilot (19kHz) is protected more than 80dB, for RDS more than 70dB and a total noise in band 60 – 100 kHz better than > 80dB
PROS: High pilot and RDS protection, low WB noise, if signal could be over 3dB CONS: Quality and Density modified.

26 STEREO GENERATOR - MPX OUTPUT SIGNAL
26.1 CONFIGURATION OF THE OUTPUT: NORMAL, PEAK TONE
Output Mode : it sets the Tiger Shark operating mode:
The Normal Operation refers to the regular operating status, with all features available. In the Peak Tone Reference mode, the Tiger Shark outputs a reference tone consisting
of a 500 Hz / 0 dBm sinusoidal signal. This tone corresponds to the maximum frequency deviation. This is helpful for an easier transmitting chain set-up.
26.2 PILOT PHASE AND LEVEL + MPX SIGNAL LEVEL
Level and phase of the MPX Pilot are adjustable from the Pc Control softwar panel as well as from the Front Panel menu and from the Web Browser.
You may also choose between a Stereo or a Mono broadcasting using the relevant drop-down menu (MPX Mode). Mono mode will turn off the Pilot and associated controls.
MPX Level it adjusts the overall level of the Stereo Composite Signal (MPX) and/or RDS signal (with or without signals injected from Aux 1 and 2 mixed into). Factory preset: 0 dBm (2.2 Vpp).
In the RDS version only, the output may be magnified by an extra-gain of 6, 12 or 18 dB (from the Front panel menu only)
Post Clipper Gain it adjusts the Gain after the clipping stage (see block diagram). It may adjusted in the + / - 12 dB range, 0.1 dB steps. Default value is 0 dB. See next paragraph.

Axel Technology srl www.axeltechnology.com | STEREO GENERATOR - MPX OUTPUT SIGNAL
77
26.3 MPX SIGNAL CALIBRATION – THE POST CLIPPER GAIN
The output MPX Composite signal is composed by:
RDS signal (whenever present) Audio components (L+R and L-R spectrums) Pilot 19 kHz
RDS and PILOT are fixed (invariable) parts in the MPX signal, while Audio Components are variable ones.
To adjust MPX output level it is recommended to start with setting desired level for fixed components in the MPX signal (Pilot and RDS) and then adjust the variable part (audio) to get 75 kHz peak deviation.
STEP 1: Adjust Pilot signal level via the MPX_Pilot Menu (recommended value: – 20 dB),
STEP 2: Adjust RDS signal level via the RDS Level menu (recommended value: –31.5 dB)
Pilot and RDS levels are expressed in Decibel (dB) with reference to the Reference Tone (500 Hz, 0 dB). If this tone is related to a Fm 75 kHz deviation, Pilot will cause a 7.5 kHz deviation (–20dB) and RDS will cause a 2 kHz deviation (–31.5 Db)
STEP 3: Once Pilot and RDS signals have been calibrated, adjust audio component via Post Clipper Gain control until the deviation hits 75 kHz reference :
The 100% modulation level (correspondent to 75 kHz with 0 dB Gain on MPX level control) is indicated by the second point in the ‘highlighted’ Zone (see picture).
75 kHz reference
The third point corresponds to a 80 kHz deviation with 0 dB Gain on MPX level control. Higher modulation levels will cause WARNING LED lighting on the front panel. That LED indicates a modulation level
exceeding 5 kHz the nominal one and/or a saturation on audio input stage.
STEP 4: Adjust the overall to apply the desired amplification / attenuation factor to nominal MPX level achieved at the Step 3.

27 RDS / RBDS GENERATOR – GENERAL SETUP
All info provided on this Chapter applies to both RDS and RBDS generation, unless differently noticed.
RBDS operation on the Tiger Shark is achieved by installing the Tiger Shark Remoter control software in
its RBDS version.
The RDS controls related to phase and levels are available from the Front Panel, while any other configuration about texts, RDS data, etc is achievable from the Pc Control Software as well as from the UECP.
Tiger Shark encoder provides two different programming modes. The first one is fully compliant to the last UECP normative.
The second one ( ‘Extended’) provides a wider range of features, which have been customized in order to make Tiger
Shark encoder more versatile and suitable for the most part of user requirements. In this case some commands are not UECP compliant When using the Remoter software, data configuration may be achieved in a textual / ASCII form (trough the Configuration Editor) or from the regular Remoter pages.
Current status of on-air RDS services can be constantly monitored from the small black screen at the upper left corner of the Tiger Shark Remoter screen.
The contents shown in the next pages refers either to the Tiger Shark in RDS version only, or to the Tiger Shark in the LIM-MPX-RDS version. Anyway, there are differences between the versions.
In the version RDS-only you may magnify the ouput level by 6, 12 o 18 dB (extra-amplification) in addition to the regular level controlled by the RDS LEVEL menu

27.3 RDS PHASE AND LEVEL ADJUSTEMENT
The RDS Level cursor regulates the RDS generation level between – 43,9 and – 20 dB, where 0 dBm corresponds to 75 KHz deviation.
RDS modulator is turned off in the Off position.
For the TIGER-SHARK – RDS version only, is available an RDS AMPLIFIER control, which adds an extra­amplification to the RDS output by 6, 12 o 18 dB. The related control is available on the Front Panel only, RDS MODULE SETUP page. This extra-amplification helps in connecting the Tiger Shark to audio processors with input level for external RDS/SCA sources set at – 20 dB
the following table lists the reationship between signal level and deviation. Default value is -31.5dB, which corresnponds to a D=2.0 KHz deviation.

For the TIGER-SHARK – RDS version only, the RDS level is expressed in mVpp units, as the level of the signal it will be mixed into is unknown. Default level is 60 mVpp (i.e. 2 KHz deviation, where 0 dBm = 2.2 Vpp).
27.4 RDS SYNC SOURCE (RDS VERSION ONLY)
The RDS Sync Source selection is available for RDS – only versions.
In the External mode, the RDS carrier locks to an external ref source. The Sync In connector on the rear panel allows synchronization of RDS signal to an external 19 KHz TTL reference signal (5 Vpp). Correct synchronization to the external reference signal will cause LED 1 on the front panel to light. Synchronization to an external MPX signal reference is achievable from AUX1 and AUX-2 connectors, too, depending on J3 jumper. TTL suitable levels: ‘0’ state < 0.5 V; ‘1’ state > 2 V See first part of this manual. Even if set on ‘External Sync’, the Tiger Shark switches automatically on the internal oscillator in the event of lack or poor quality of the external ref source.

General Purpose DataSet 1 menu comprises all the settings related to the Main network (which is braodcasting the DataSet) and to up to 10 EON (Enhanced Other Networks). It is available also another page (Services) for enabling/configuration of RDS services supported in the DataSet
29.2 RDS GROUP CONFIGURATION (‘services’ PANEL)
As in UECP protocol, Service panel allows you to enable single RDS services/features (f.i. PIN, RT, etc) and to compose the Group Sequence carried by the RDS signal.
Tiger Tiger Shark accepts all the listed groups and reaches a maximum of 64 elements. Only group 4A (automatically generated) and 15A (not supported) are excluded. This feature matches with ODA management that allows to use any group for bridging the information.
When any group is specified, the Tiger Shark generates the 0A group as default, which carries all the RDS basic services (PS, DI, M/S, TP, TA, PTY, AF). The 4A group (which carries clock information) is automatically managed by the Tiger Shark and it is not user-settable.
In the event You would like to broadcast additional services to those included in the 0A Group, You will need to broadcast a Group sequence. That sequence may be generated manually with Drag And Drop catching the corresponding number group in “Groups” and dragging the number in “Group Sequence”

29.3 EON / PSN SERVICES IN THE DATASET 1
The PSN (Program Service Number) List represents the reference List for all UECP index. It allows to associate the various PSN (i.e. RDS configurations) to Main networks and to EON networks, so that a same UECP command (for example the TA) can be brought at the same time to each Coder no matter of the network it belongs, resulting in the TA activation on the Main network and the EON-TA activation on the linked network.
To change the PSN assignment in the PSN List You just have to click the chosen PSN and drag it on the desired position. After that, enable each individual assignment by clicking on Enable box.
For example, to assign the PSN 5 to the Eon 2 (instead of the default PSN 3), click PSN5 and drag it in the current position of PSN 3. Then enable the Eon2.
NOTE: PSN List modification can be done only on Dataset unactive.
EXAMPLE If You have 3 RDS coders broadcasting 3 programs (Radio 1, Radio 2 and Radio3) and an unique TA - UECP command
brought at the same time to each coder, PSN Lists on the 3 coders will be the following:
RADIO 1
RADIO 2
RADIO 3
EON Fast Switch option (group 14B) shall be selected when a large number of groups (either Main or EON) is
braodcast, in order to make more timely a change in the status of the TA flag of a cross-referenced programme service. Some early RDS EON consumer receivers may need up to four correct type 14B groups for reliable functioning.
Therefore, if manual group mode has been selected, it is recommended to broadcast as many as possible of up to 8 type 14B groups, in order to ensure the detection of the TA switching under bad reception conditions.

29.6 ‘LINKAGE’ INFORMATION (LA, EG, ILS, LSN)
They are accessibile in the ‘Basic Services’ panel.
Linkage information provides the means by which several programme services, each characterised by its own PI code, may be treated by a receiver as a single service during times a common programme is carried. During such times each programme service retains its unique identity, i.e. the programme service must keep its designated PI code and its AF (Alternative Frequency) list(s), but may change programme related features such as PS, PTY, RT, TP and TA to reflect the common programme;
With LA=1, a service carrying codes TP=1 or TP=0/TA=1 must not be linked to another service carrying the codes TP=0/TA=0.
Linkage information is conveyed in the following four data elements:
1) LA - Linkage Actuator (1 bit)
2) EG - Extended Generic indicator (1 bit)
3) ILS - International Linkage Set indicator (1 bit)
4) LSN - Linkage Set Number (12 bits)
29.7 TP, TA, MS CONFIGURATION & THEIR REMOTE CONTROL

TP - Traffic Programme is a flag to indicate that the tuned programme carries traffic announcements. The TP flag must only be set on programmes which dynamically switch on the TA identification during traffic announcements. It can be set as Disabled or Enabled.
TA - Traffic announcement identification is an on/off switching signal to indicate when a traffic announcement is on air. To enable it, see next lines.
TA and M/S status may be:

29.9 ALTERNATIVE FREQUENCIES (AF)
The list(s) of alternative frequencies give information on the various transmitters broadcasting the same programme in the same or adjacent reception areas.This facility is particularly useful in the case of car and portable radios.
NOTE: Overall 500 alternative frequencies max can be entered for each DataSet. The alternative frequencies (AF) list can be transmitted following two methods: A Method and B Method. In both cases, lists should only contain frequencies related to the closest transmitters (i.e. frequencies with overlapping between coverage areas).
NOTE receivers are able to get which Method (A or B) is used from their data organization (coupled frequencies
or single frequencies). There is any direct ‘identifier’ for that.
The Tiger Shark offers to the user the max freedom in using Method A or Method B in the list composition and, in particular, whether freq pairs are listed in descending or ascending order within the B Method.
Receiver’s behaviour could differ from one model to the other. The examples shown in these pages are for
information purpose only and to present Tiger Shark potentialities in the AF programming. Refer to Cenelec normative for a complete treatment on AF programming.

29.10 HOW TO COMPOSE AF LISTS
First loading method (Drag & Drop) Select the AF from the available frequencies in the left window by clicking left it
and drag & drop it into the AF list. Release the mouse left button to ‘drop’ the frequency into the desired AF list.
Second loading method (preselected AF list) Highlight the AF list to be loaded by clicking on it. The selected column will turn red with a bright tone. At this point, double click desired items on the general list: they will automatically appear into the highlighted AF list.
- “U” button Arrange AFs
- “B” create Method B AF list
- “R” restore AF previous order
Clicking RIGHT You can remove ALL frequencies from the highlighted list or from ALL the lists. Lists containing at least one item (i.e. not empty) are shown in blu color.
-
To remove a frequency from the list, click LEFT and then drag it onto the ‘trash’ icon (alternatively,
click ‘Canc’ button). By clicking with the Right button of the mouse on the skeltor trashed it’s possible to
delete only a list of AF Frequency
Then it’s possible top selecrt the AF List to delete and pressing OK delete it.

29.11 AF METHODS A AND B
There are two ways to transmit lists of alternative frequencies: Method A and Method B. In both cases the lists should include only those frequencies for the nearest transmitters and repeaters (with overlapping coverage areas). Generally speaking, Method A is used when the list contains no more than 25 frequencies, and Method B when the list is longer (for a maximum of 24 lists). Method B is recommended when splitting areas or when different programs are broadcast.
NOTE: use of encoding method A or B is not explicitly assigned by a dedicated signal to the receiver, as the latter is capable of identifying which method is used by analyzing the transmitted data structure (whether or not they are organized in pairs).
METHOD A
Compile the AF1 list assigning the tuning frequency (i.e. the frequency carrying the list of alternative frequencies) in the first position, and then continue in strictly increasing order with the alternative frequencies transmitting exactly the same program.
We recommend recording the alternative frequencies (those of adjacent transmitters and repeaters with overlapping coverage areas) on each transmitter, being careful that the first position indicates the frequency carrying the list of alternative frequencies.
For example, in the situation shown in the figure three transmitters (B, D, E) intersect only in two coverage areas: between B and D, and between D and E. The following lists should be loaded in each transmitter:
Tx B lists
(tuning frequency: f Tx B)
AF1
AF2
Note that the frequency of transmitter C is not included
in the list, since the latter’s coverage area does not
overlap with that of transmitter A
f Tx B
f Tx D
f Tx D
f Tx B
Tx D lists
(tuning frequency: f Tx D)
AF1
AF2
AF3
Coverage area D partially overlaps that of both
transmitters B and E, and thus it is recommended to
load the lists for both adjacent transmitters. Be careful
to list all frequencies above the tuning frequency in
ascending order.
f Tx D
f Tx B
f Tx E
f Tx B
f Tx D
f Tx D
f Tx E
Tx E lists
(tuning frequency: f Tx E)

AF2
Note that the frequency of transmitter B has not been
included in the list, since its coverage area does not
overlap with that of transmitter E.

METHOD B
As mentioned earlier, Method B is used with high numbers of alternative frequencies and/or when the transmitter also has frequencies that broadcast different radio program at various times of day (splitting, local programming, etc.).
In the latter instance, the mobile receiver should check whether the AF is broadcasting the same content before selecting another frequency.
Each list begins with the tuning frequency (for which the list is valid) and then contains up to 12 pairs of frequencies in sequence, each containing the tuning frequency and an alternate. If there are more than 12 possible alternative frequencies, the list continues in other lists in the same manner.
The order of the frequencies in each pair follow the rules below:
- If the order is increasing, the alternative frequency broadcasts the same programming as the tuning frequency.
- If the order is decreasing, the two frequencies have different programming.
Returning to the example of transmitters B, D and E in the previous paragraph (in which the coverage areas of D and E do not overlap), two more lists will be assigned to transmitter B, sorted according to the above criteria to take into account any different programming by some of the AFs.
Tx B
(tuning frequency: f Tx B)
AF1
AF2
Notice that the tuning frequency f Tx B is repeated twice in list 1: in the first position, then paired with f Tx D. Tx B broadcasts the same program as D if f Tx B < f Tx D, and different programs if f Tx B > f Tx D.
f Tx B
f Tx D
f Tx B
f Tx D
f Tx D
f Tx B
The AF lists for the other transmitters are compiled according to the same criteria, alternating the frequency pairs. NOTE: if the same tuning frequency is used by more than one transmitter within the same network, the corresponding AF lists must not be consecutive (for instance AF 1 and AF 2). Lists for different tuning frequencies must be placed between them.

29.13 PIN – PTY SERVICES
PIN / PTY EDITOR allows you to set up to 32 different Pin / Pty / Ptyn items.
- PIN - Programme Item Number The PIN code should enable receivers and recorders designed to make use of this feature to respond to the particular programme item(s) that the user has preselected. Use is made of the scheduled programme time, to which is added the day of the month in order to avoid ambiguity.
- PTY - Programme Type This is an identification number to be transmitted with each programme item and which is intended to specify the current Programme Type within 31 possibilities. This code could be used for search tuning. The code will, moreover, enable suitable receivers and recorders to be pre-set to respond only to programme items of the desired type. The last number, i.e. 31, is reserved for an alarm identification which is intended to switch on the audio signal when a receiver is operated in a waiting reception mode.
- PTYN - Programme TYpe Name The PTYN feature is used to further describe current PTY. PTYN permits the display of a more specific PTY description (max 8 characters) that the broadcaster can freely decide (eg PTY=4: Sport and PTYN: Football). The PTYN is not intended to change the default eight characters of PTY which will be used during search or wait modes, but only to show in detail the programme type once tuned to a programme. If the broadcaster is satisfied with a default PTY name, it is not necessary to use additional data capacity for PTYN. The Programme Type Name is not intended to be used for automatic PTY selection and must not be used for giving sequential information.
NOTE: the MAIN PTY only can be programmed accordingly to the UECP protocol. The other fields (from PTY/PIN 01 to PTY/PIN 31) are related to the UECP Extended (custom) RDS programming mode.
To enter PTY/PIN:
-
select a field (MAIN PTY, PTY01, PTY02, etc) clicking on the ‘yellow’ zone: the selected raw will be displayed at the bottom of the window (f.i., the picture here above shows PTY 1 selection).
-
Select PIN Date/Time (Day, Hour, Min) and PTY from the list. Type an additional PTYN (8 char max) into the field at the bottom.
-
click the ‘Update’ button
to update the data or click
to discard it.
NOTE: Main PTY/PIN (also indicated as PTY 00) is broadcast by default. The SCHEDULER panel (see NEXT PAGES) allows You to schedule many PTY sequences.

29.14 PROGRAM SERVICE NAME (PSN)
PSN - Program Service Name is a text consisting of not more than eight alphanumeric characters which is displayed by RDS receivers in order to inform the listener what programme service is being broadcast by the station to which the receiver is tuned. An example for a PS name is "Radio 21". The Programme Service name is not intended to be used for automatic search tuning.
NOTE: MAIN PSN only can be programmed accordingly to the UECP protocol. The other fields (from PS1 to PS59) are related to the UECP Extended (custom) programming mode.
To enter PSNs:
-
select a field (MAIN PSN, PSN1, PSN2, etc) clicking on the ‘yellow’ zone: the selected field will be displayed at the bottom of the window (f.i., the picture here above shows PSN 4 selection).
-
select and remove the text displayed by default (f.i. PSNAME 03) from the field at the bottom
-
type the new PS Name (8 char max)
-
click the ‘Update’ button
to update the message or click
to discard it.

29.15 VARIABLE PS - BASIC OPERATION
Here below are provided some basic tools for the management of variable PS. For an advanced PS scheduling / programming please refer to Scheduler panel (next paragraph).
29.15.1 PS SEQUENCES
UECP Extended mode of Tiger Shark allows You to easily create and broadcast sequences composed by up to 60 PS Names. For each PS, You can also set its ‘display speed’ (related to the time it will last on the receiver display).
To enter the single PSNs componing the sequence, plese refer to the previous page.
A different ‘display rate’ can be set for each message. Available options are listed in the PSN SPEED
pop-up menu (slowest, slow, normal, fast and fastest). NOTE: the time needed for a receiver to properly receive and display a message is dependent upon
the following:
- numbers of characters in the message
- repetition rate of data group / overall number of groups carried out by RDS signal
- reception conditions at the receiver
- software implementation of PS feature Further to these conditions, it is not possible to set a precise time duration for each PSN (i.e. number
of seconds). Any way, ‘normal’ rate factor corresponds to an average display time of around 3
seconds. Please remind that fast and fastest rate factors are advisable only whenever a large
number of groups is carried out by RDS signal. See also ‘Warning’ note at the end of this Paragraph.
The ‘Stopped’ option allows You to keep constantly displayed a specific PSN. This feature is very
useful when many PS sequence are scheduled through the Scheduler panel (see next paragraph). Please make sure no stopped PSN are set in the middle of a PS sequence.
Default PS Sequence window allows to configure a PS sequence (or PS carousel) in a very easily and quickly way. Please note that this Sequence can not be scheduled (i.e., it can not be automatically changed during the day, the week, etc ).
It is intended to be on-air whenever no PS Event are scheduled (i.e. it should be used to ‘fill’ possible lacks in Event overlapping
To create a default sequence, You have just to select the last item of it, as the first item is set by default (Main PSN).
F.i., accordingly to the settings as in the picture here closed the PS sequence broadcast at all time will be: RADIO 1 / RAI / RADIO/TV / ITALIANA

29.15.2 PS SCROLLING
The Dynamic Program Service Scrolling is a special feature that bring in PS Name a Scrolling message. For setup this message enter in the
Dynamic Rds section and set the message in PS Scrolling Message. It’s
possible to set le Scrolling Repetition, the Number of Character per Step and the Scrolling Speed in the
Please, make sure PSN is enabled (Basic Tuning group) in the Main RDS SERVICE panel. The Group is 0A
WARNING: if the PS is constantly changed (as in the PS Scrolling mode), it is possible that some receivers will
display a mixture of old and new PS message on the same display. In some cases, no PS will be displayed at all. This may occurs as message byte group order is not univocally recommended by the CENELEC RDS standard and strictly depends on the coder/decoder physical implementation. Neither the RDS encoder nor the car receiver are faulty. In case of PS Scrolling selection, we therefore suggest to choose low display speeds.
Services panel provides GENERAL ENABLING of every RDS Service. Once You have configured PSN
messages MAKE SURE the related Group (Basic Services) is ‘checked’ on the Services Panel and included in
the outgoing RDS Group sequence.

29.16 THE SCHEDULER
Scheduler enables you to organize RDS broadcast on a ‘round the clock’ daily, weekly, and monthly basis. You use Scheduler to make Tiger Shark broadcasting / changing specific RDS features (PS, PTY/PIN) at specific times and dates.
The changes to a schedule are immediately saved and implemented. Your scheduling work goes into effect (i.e. ‘on air’) in max 1 minute.
The basic unit of the Event Scheduler is the event, which is an RDS feature (PS, PTY/PIN) that can be configured to launch automatically at a specified time and date or to launch cyclically at a specified interval.
The Events have two properties that define how they work: operational properties and chronological properties. Operational properties determine what the Event does (i.e. the type of event) and Chronological properties determine when the Event launches.
Scheduler programming capabilities are very flexible, allowing you to set the duration of each event, from 1 minute to 365 days per year, in 1 minute increments. Up to 64 events can be stored in the Tiger Shark memory. Event Scheduler provides the capability to configure four types of event (PS, PTY/PIN) to occur at any time.
Some examples are listed below:
- You can schedule a new PSName to be on air at a aspecified interval (f.i. form 6:00 to 12:00).
- You can schedule a specific PTY to launch at 14:00 every morning
Tiger Shark will investigate every minute for a new scheduled event and will activate it. A new scheduled event may be therefore broadcast within 1 minute. Please note that Tiger Shark will scan scheduled events from the bottom to top of the Scheduler table. It means: if two events are partially or fully overlapped in the time, Tiger Shark will execute the event
with the highest index (see NEXT pages). YOU WILL NEED THE TIGER-SHARK CLOCK ALWAYS ‘ON-TIME’ TO GET THE MOST RELIABLE SCHEDULER OPERATION
You can activate or deactivate any single event at any time using the Enable option provided for each event. NOTE:
- Change between 12- and 24-hour format is not available
- A cross-referenced Preview Bar is provided: this is a quick way to find out which item You are scheduling
This section provides you with a general working knowledge of the Scheduler features and a step-by-step programming instructions. In particular, it describes how to insert the items (PS Names, etc) that you have already created into blank event slots (raws) in the Schedule Table.
