The AUTV/3500LD series represents the 3,5kW TV Transmitters operating in the IV/V Band for Common amplification process (separate amplification available) of the Vision and Sound carriers. This Transmitters family has been designed to offer to the customer high performances, high reliability and greater simplicity in their operation and maintenance procedures. The Vision and Sound signal processing is provided for all TV Standards and all types of Audio applications (Mono & Dual sound - NICAM) together with colour systems such as PAL - NTSC - SECAM. Thanks to the amplitude and phase pre-correction circuit, it is possible to cancel the distortions in the output stage, thus cutting down the operating costs. The RF transposition in the driver is carried out by a synthesizer with various possibilities of accuracy and stability as well as precision offset locked by internal or external frequency reference. The RF amplifier is made up by three RF modules installed in a power rack, the modules are dedicated for the Vision and Sound carriers common amplification. The amplifiers employ solid state LDMOS technology in order to obtain wide band, reliability, and high efficiency. Each RF module has a built-in switching-mode power supply unit, self-protected against overcurrents and overvoltages, as well as overtemperature and VSWR for RF parameters. The cooling system is fully contained into the transmitter. The control unit provides full management of the transmitter without the presence of the operator, the system includes a central controller and several peripheral units installed in each RF module and rack. The control device includes a fault finding system to detect equipment malfunctions and locate the faulty subassembly which needs to be replaced. The interlock circuit is independent on the software and remains always operational whether computer control is present or not. The operator interface is made by a high resolution LCD graphic display and a simple keyboard, the menu is very friendly and easy to use. The Control Unit can be fully controlled in REMOTE mode via link or via modem in RS232 or other interface. The equipment design allows the soft degradation (RF power loss) for several transistors faults. 12 TECHNICAL CHARACTERISTICS RF SECTION Frequency range Output power Vision / Sound power ratio Out stage technology Vision / Sound amplification Standards Sound transmission Harmonics and spurious emission Intermodulation products from vision and sound Frequency stability 470 - 860MHz 3,5kW PEP 10/1 single sound - 20/1/0.2 dual sound Solid State LDMOS Common G, K, I, M FM single sound - Dual sound coding IRT - NICAM 728 In compliance with CCIR rec. < = 56dB 2,5ppm (option 0,05ppm) VISION SECTION Video input Nominal input level Return loss DC Restoration White limiter BNC 75W connector 1Vpp ± 6dB > = 30dB Clamped to the blanking level without affecting the burst At 90% picture signal without affecting the chrominance Transmission characteristics Sideband spectrum response Amplitude frequency response Group delay variation without receiver pre-correction and TV demodulator in flat Non linearity distortion (10 to 75% mod.)

The number of the Slaves changes depending on the output power of the amplifier. The communication between Master and Slaves is made via RS485 standard. The Master board reads the overall parameters of the equipment (Forward and Reflected power and Unbalancing), polls (interrogaes in sequence) the local boards, shows on the display the values requested by the user, indicates alarm conditions, if any, and allows to change some of the operating parameters of the apparatus. Besides it realizes a serial data interface to an external system able to analyse the working parameters of the equipment, using the RS232 and RS485 communication protocols. 1.2 FUNCTIONS At start-up, the display of Amplifier Control module shows an informational message concerning the equipment and its firmware version. - Main menu The main menu has: a list of the amplifier modules, the measure of some parameters of the power in antenna, a window with icons to show the alarm status (Alarm Status Window) and some general information, that is date, time, temperature inside the module and, for FM equipment, transmission frequency. The following picture is an exact representation of the main menu screen. 16 In the Amplifier List, next to each module, the following symbols can be found: if the communication with the slave is correct and then ON if the amplifier module is ON OFF if the amplifier module is OFF if the communication with the slave is interrupted The UP and DOWN arrow keys allow to select one of the slave, the alarm list, or a menu allowing to change some settings of the control module and the apparatus; the RET key is used to confirm the selection. In the main and slave menu the Alarm Status Window (which position is indicated by an arrow in the picture below) is shown: the gate symbol displays the status of the INTERLOCK, in case of alarm this icon blinks and the buzzer ringgs. The INTERLOCK signal is a control available to the user to manage an ON/OFF sensor. When the relevant PIN is grounded, the Master board does not signal any alarm, as soon as the PIN is left floating, an alarm is detected; the rotating screw symbol shows that the FANS work normally; in case of alarm this icon blinks and the buzzer rings; the bell symbol appears in case of alarm detected by the control module or the amplifier. It blinks if the alarm condition is terminated and the alarm itself can be displayed in the Alarm List. If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, the general 17 alarm LED and the alarm icon blink until the Alarm List is checked to see the type of alarm occurred. Besides, if an alarm for any of the powers of the signals in antenna occurs, the relevant measure in the Antenna window of the display and the relevant LED on the front panel of the Master module blink until the measure decreases below the threshold level, determined by the nominal power of the amplifier. If the slave modules are working and an INTERLOCK or FANS alarm occurs, aside from the indication explained above, the amplifiers are switched off. This happens immediately after an INTERLOCK alarm, or about 7 seconds after a FANS alarm is detected. In case the amplifiers are communicating but switched off, or they are not communicating and the INTERLOCK alarm contact is open, a WARNING condition occurs: buzzer on and blinking ALARM LED on the front panel; while if it is the FANS alarm contact to be open, the icon of the alarm appears in the box. Further to any of these two alarms it is possible to choose whether to turn off the amplifiers or not. In fact, there is a submenu of the Settings menu which allows to choose whether to turn off the amplifiers connected to the control module as a consequence of an INTERLOCK and FAN alarm. - Slave menu By selecting one of the slaves, it is possible to see all the parameters of that amplifier module in two pages. The first one shows voltages and currents Power Supply, the second one shows RF Powers: forward and reflected power, temperature and, for some amplifiers, unbalancing and input power. The UP and DOWN keys allow to scroll the local measures of all the slaves, page by page. The ESC key is used to go back to the main menu. The following pictures show the menu screen of one amplifier. Note that no numerical value is shown for amplifiers which are not communicating with the control module. 18 - Alarm List By selecting the Alarm List, 26 pages listing the latest 130 alarms saved are shown. Each page shows 5 alarms, each contained in a box providing the following information: progressive number of the alarm, starting with the most recent; number of the module in which the alarm occurred, following the Blk. Message (the indication AC means that the alarm occurred in the Amplifier Control module); parameter in alarm, date and time of the alarm. Next to the parameter showing the alarm type there may be a bell symbol. In case it is not here, the alarm event has been communicated by an amplifier connected to the control module. These events are different and on option of the Settings menu allows to choose whether they are displayed or not in the alarm list. The saved alarm can be deleted by keeping simultaneously pressed the UP and DOWN keys. The ESC key is used to go back to the main menu. The picture shows a page of the list, containing both alarms and general events. 1.3 PROGRAMMING MODE The Settings menu gives access to programming mode. As shown below, the menu offers a list of settings next to a window showing the default parameter set, or the one selected previously, when the pointer is moved on the relevant options. The menu under the cursor is accessed by pressing the RET key. This is shown by the Enabled Menu. Once 19 the menu is accessed, it is possible to change the value of the displayed fields or select a function by means of the arrow keys. The RET key is used to confirm the selection (an acoustic signal should be heard). The ESC key (or no key pressed for more than 7 seconds) sends back to the setting list. Pressing it again (or pressing no key for more than 10 seconds) brings back to the main menu. Every selection made in the Settings menu is stored into the EEPROM until it is changed again, this allows to remember the settings status after an equipment reset. Description of the submenus included in Settings. SUBMENU OPERATION Clock / Date Update the time and date shown in the main menu box. FWD Read Mode Selection of the analogue voltage signal (PEAK or RMS) to convert and display the Forward power in antenna. A message in the main menu screen confirms current choice. Remote Control It is possible to remotely control the apparatus, thus to monitor the parameters shown on the display of Amplifier Control module and check the status of the transmitter. This is done through RS232 or RS485 standard serial communication, digital and analog inputs through the DB25 telemetering connector on the rear panel of the Amplifier Control module. If the Local mode is set in this menu, the control module and the apparatus can only be controlled locally, and a remote command is ignored. If Remote is set instead, the REMOTE LED on the front panel of the module lights up after going back to the main screen. From then on, incoming remote commands from either the serial port or the telemeasuring connector on the rear panel are handled (Note 1). 20 Serial Comm Selects the remote control via serial port. RS232 MODE: the RS232 mode allows a direct access to the equipment via PC and a remote access via modem or switched telephone line. RS485 MODE: the RS485 mode allows a remote access to the equipment via modem over switched telephone line or GSM network. It allows the connection to the Remote Control System, designed to monitor several apparatuses located at the same site. Buzzer Enables / disables the buzzer during normal operation. FAN Alarm Select OFF to have the amplifiers turned off further to a FAN alarm; if ON is selected, they will stay on. INT Alarm Select OFF to have the amplifiers turned off further to a INTERLOCK alarm; if ON is selected, they will stay on. LOG Mode Select only alarms to store in the EEPROM and display in the module LOG only detected alarms; select all events to store and display also any event detected by any amplifier and sent via RS485 to the control module. Working Timer Updates the counter of the working time of the transmitter. Once this menu has been enabled, the counter reset option appears in the window. Backlight If Switch Off is selected and no key is pressed for 8 minutes, the back light of the display is turned off; select always ON to have it always on. Frequency This menu only exists in the firmware for Amplifier Control of FM transmitters. The working frequency can be selected within a range from 88 to 108MHz, this allows to optimise the display of the Forward power sent to the antenna. Thresholds info Shows for some seconds the alarms thresholds of the powers sent to the antenna. Release info Shows for some seconds information concerning the transmitter and the firmware version. Note 1: to control the apparatus from remote, consider that pins n. 1 and n. 14 of the telemetering connector on the rear panel of Amplifier Control module are used to receive the ON (pin n. 1) and OFF (pin n. 14) commands, both impulsive and stationary. The digital level on these contacts is usually high, becoming low when the remote control is active. When a remote command to turn off the amplifiers is received while the transmitters is ON, the LED ON of the frontal panel blinks. 21 1.3 POWER CALIBRATION - FWD Power calibration Disconnect the antenna and connect a wattmeter to the antenna connector. Give power to the amplifier until you will read on the wattmeter a value corresponding to the equipment nominal power. Then turn the trimmer A (see mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the A analog input measure) until you read approximately the same FWD power value on the display. - REF Power calibration Disconnect the antenna and connect a wattmeter to the antenna connector. Connect the Forward power monitoring cable to the Reflected power input connector. Give power to the amplifier until you will read on the wattmeter a value corresponding to 10% of the equipment nominal power. Then turn the trimmer B (see mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the B analog input measure) until you read approximately the same REF power value on the display. - UNB Calibration Connect a wattmeter before the dummy load. Give power to the amplifier then turn off one slave module: you will read an amount of unbalancing power on the wattmeter. Turn the trimmer C (see mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the C analog input measure) until you read approximately the same UNB power value on the display. 1.4 RS232 AND RS485 PIN TABLES PIN N° SYGNAL TYPE IN/OUT FUNCTION PIN N° SYGNAL TYPE IN/OUT FUNCTION Digital Output TX232 Digital Input RX2_485B- Digital Input RX232 Digital Input RX2_485A+ GND GND VDC +5V Digital Output TX2_485Z- Digital Output TX2_485Y+ RS232 - DB9 Connector (Front panel) 22 RS485 - DB9 Connector (Rear panel) 1.5 TELEMEASURING PINS TABLE PIN N° SIGNAL TYPE IN / OUT FUNCTION Digital Digital Output Digital Output Digital Output Digital Output Digital Output Digital Output AGC alarm TTL: GND = AGC alarm, +5V = no AGC alarm Digital Output GND 10 Analog Output 11 Analog Output 12 Analog Output 13 Analog Output REMOTE ON/OFF TTL: GND = REMOTE ON +5V = REMOTE OFF REMOTE AMPLIFIER ON/OFF TTL: if REMOTE ON then GND = AMPLIFIER OFF +5V = AMPLIFIER ON 14 Digital Input 15 Digital Output 16 Digital Output 17 Digital Output 18 Digital Output 19 Digital Output AGC alarm TTL: GND = AGC alarm, +5V = no AGC alarm 20 GND 21 +5V 22 Analog Output FWD Power [0,+ 5V] 23 Analog Output REF Power [0,+ 5V] 24 Analog Output UNB Power [0,+ 5V] 25 Analog Output 23 1.6 OTHER TABLES SYGNAL TYPE IN/OUT FUNCTION Analog Input FWD Power monitoring Analog Input REF Power monitoring Analog Input UNB Power monitoring BNC Connectors PIN N° SYGNAL TYPE IN/OUT FUNCTION GND Digital Output AGC alarm TTL: GND = AGC alarm, +5V = no AGC alarm Digital Output AGC alarm TTL: GND = AGC alarm, +5V = no AGC alarm Analog Output FWD Power (range 0 - +5V) Analog Output FWD Power (range 0 - +5V) AGC Connector 24 BNC SYGNAL TYPE IN/OUT Contact Digital Input Body GND FUNCTION FANS control Switch or TTL: closed/GND = no FANS alarm open/+5V = FANS alarm FANS CONTROL Connector PIN N° SYGNAL TYPE IN/OUT FUNCTION Digital Output TX1_485Z- Digital Output TX1_485Y- GND Digital Input RX1_485B- Digital Input RX1_485A+ RS485 - DB9 Connector (Amplifiers communication) PIN N° SYGNAL TYPE IN/OUT FUNCTION GND VDC +24V 24VDC LOAD FAN Connector 25 Front panel Status LEDs Alarm LEDs RS232 Socket LCD Display Function keys RF Monitor connector ON/OFF Switch 26 RS232 MICROPROCESSOR CONTROLLED SYSTEM DESCRIPTION Rear panel RF Input connector Main Power supply socket with Fuse-Holder by 10A Driver1 Power socket Driver2 Power socket Fans Power socket GND Fuse by 1A Fuse by 8A 24Vdc Connectors 10 AGC Socket 11 Telemeasures socket 12 Fans Control connector 13 RS485 Socket (Amplifiers Communication) 14 RS485 Socket (Remote Control) 15 Interlock connector 16 Power measurement connector 12 10 16 13 14 11 15 DESCRIPTION 27 28 Component list APG012C - Amplifier Control Part Name Code Description Qty CON0145 05504 05525 PAN0066 CON0153 0552B 02880 SCH0239AR0 SCH0110BR0 SCH0152AR0 SCH0241AR0 E0031 07926 02843 02695 02856 07925 07524A 02018 02035 08500 02700 02790 02871A C0814 V0761 CON0145R0 POST.

The amplifier has been designed to offer to the customer high performances, high reliability and greater simplicity in his operation and maintenance procedures. The amplifiers modules employ all solid state LDMOS technology in order to obtain high gain, wideband performances, very good linearity, reliability and high efficiency. The equipment design allows the soft degradation (RF power loss) for several transistor faulty: in fact the output combiner uses RF power resistors for unbalancing power dissipation. The unit is enclosed in a cabinet for 19- 6U rackmounting. 54 1.2 TECHNICAL CHARACTERISTICS RF GENERAL PROTECTION THR.

In any case, the area should be as clean and well-ventilated as possible. Always allow for at least 2 cm of clearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacers on the bottom cover plate. If you install the apparatus in a rack, provide adequate clearance above and below. Do not locate the apparatus directly above a hot piece of equipment. 2.2 PRELIMINARY OPERATIONS Correct installation of the equipment is important for maximum performance and reliability. Antenna and earth connections must be installed with the greatest care. The equipment adjustment isnt need, because the unit is completely adjusted by our technical staff. This is the installation procedure: 1. connect the power supply cable of the exciter to the auxiliary socket on the rear panel of the amplifier; 2. connect the power supply cable of the amplifier to the electric network (230VAC). If there is the Isolator Transformer, the amplifier is provided with cable and plug; 3. connect the exciter / antenna cables respectively to the RF IN and RF OUT on the rear panel of the amplifier. Monophase cabling Three-Phase cabling WARNING!!! FOR ELECTRICAL SAFETY REASONS AND IN ORDER TO KEEP THE APPARATUS SAFE, THE GROUND TERMINAL OF THE APPARATUS MUST BE CONNECTED TO THE EXISTING GROUNDING SYSTEM AND NOT BY USING THE SHIELD OF THE OUTPUT COAXIAL CABLE. 58 When the apparatus is put within a combined system it is directly connected to the input splitting and output combining systems. Before fully powering the apparatus, check that the output connections of the coaxial cable to the antenna system are working. In order to this it is possible to check the indication of the reflected power at low power levels. Only if the SWR indication on the display is 0, the output power can be slowly increased. At maximum output power, some watts might be shown as reflected power. 2.3 TELEMEASURING SOCKET CONNECTIONS PIN N° DB9 Socket SIGNAL TYPE IN / OUT FUNCTION Analog Output FWD Power Analog Output REF Power Digital Output Temperature Digital Input GND 6-7 Digital Output Free contact (closed when alarm) Digital Input 0V = ON 5V = Normal Digital Input 0V = OFF 5V = Normal Interlock 2.4 RS232, RS485 AND AGC SOCKET CONNECTIONS PIN FUNCTIONS TxD RxD GND RS232 - DB9 Socket PIN FUNCTIONS Rx- Rx+ 5V GND Tx- Tx+ RS485 - DB9 Socket 59 PIN N° SIGNAL TYPE IN / OUT FUNCTION GND Digital Output 0V = Normal 5V = AGC Alarm Digital Output 0V = Normal 5V = AGC Alarm Analog Output FWD Power Analog Output FWD Power AGC - DB9 Socket 2.5 PREVENTIVE MAINTENANCE To ensure maximum performance and minimum repair trouble, we strongly recommend you to follow the below stated headlines for preventive maintenance: 1. check antenna installation and ground connection at regular intervals; 2. keep your apparatus clean and dry externally: this will ensure continuous functioning of the front panel controls; 3. if the apparatus has not been used for a long period of time combined with exposure to extreme environmental conditions, open the unit and make a visual inspection. Remove salt, water or ice with a moist cloth before turning the apparatus on. Check that the cooling fans are running freely. 4. for general maintenance and top performance, call an authorized service technician to give the apparatus and the complete antenna/earth connection installation a general check every 12-18 months; 5. check at regular intervals that the air intake located on the front panel is free of dust. If there is visible dust, remove it by means of a soft brush. 60 Front panel LCD Display Function keys Status LEDs RF Monitor connector Main switch RS232 Socket DESCRIPTION 61 Rear panel DESCRIPTION 62 Breaker Power supply socket Auxiliary socket Fuse RS485 Socket AGC Socket Telemeasure socket RF Input connector RF Output connector _______________________________________________________________________________________________ Section 3 - Operation Contents: 3.1 Operation 3.2 Display 3.3 Menus 63 3.1 OPERATION At startup, after initial image, the display shows the main screen with the RF powers as in Figure 1: Figure 1: Main screen The user may turn on and off the amplifier by means of the switch on the front panel. The control board turns on all the power supplies, the exciter (if any), and internal cooling fans. While the amplifier is working, the micro-controller monitors continuously the most important parameters: power supply voltages, absorbed currents, high power zone temperature, forward and reflected powers, unbalances (if any). Each measure is associated to a maximum threshold beyond which the amplifier is immediately put in protection status by turning off one or more power supply, depending on the failed block. In order to prevent a temporary problem to trigger a definitive protection status, the failed block is turned on again, after some seconds, for up to five times. If it goes beyond the protection threshold for more than five times, it is declared as FAILED and it will no longer be turned on. In this case, the amplifier will have to be turned off manually by means of the switch on the front panel, then turned on again after performing the needed maintenance. On the front panel there are also three LEDs labelled ON, REMOTE and ALARM. Their meanings are explained in Table 1. LED COLOUR MEANING MEANING WHEN BLINKING The amplifier has been turned on locally but it has been turned off by remote ON Green The amplifier is on REMOTE Yellow Re mo te c o ntro l i s It never blinks enabled ALARM Red An alarm is present It never blinks Table 1: Meanings of the three LEDs on the front panel Screenshots in this manual are indicative, so they can be different from those on your equipment. 64 3.2 DISPLAY The control board is provided with a modern pixels graphic display with blue background. Normally it always shows a title bar (on the top line) and a status bar (on the bottom line). The title bar, see Figure 2, shows the name of the amplifier (TV Amplifier) and the current time. If the amplifier is a single unit coupled externally with other units in a high power transmitter, the title bar shows the amplifier number (slave address) too. Figure 2: Title bar The status bar (Figure 3) indicates the forward and reflected powers and the temperature. It also contains two symbols for the interlock (lock) and the alarm (bell). Figure 3: Status Bar The bell symbol is continuously displayed in case of alarm. It blinks if there has been an alarm which has ended but has not yet been seen by the user. It stops blinking once the Log has been checked. The interlock symbol is displayed only when this function is enabled. It may be either a close lock, as in Figure 3, when there is no alarm (interlock chain closed) or an open lock in case of alarm (interlock chain open). Since the status bar is always showed on the display, regardless of the screen, the user may monitor at any time the most important parameters and the presence of alarms while moving between different screens. 3.3 MENUS The user may see or modify locally some configuration parameters using the four buttons on the front panel. All screens areorganized in a hierarchical menus and the user may move between them in a simple and intuitive way. To see the menu its sufficient to press the ESC key (see Figure 4). 65 Figure 4: Main menu The display only shows three items at a time: all the items can be scrolled by the UP and DOWN arrow keys. Any item can be chosen by selecting it and pressing the RET key. Menu entries with an arrow on the right open sub-menus when chosen. Thus there is a hierarchical structure as in Figure 5. To go back from a submenu to the previous menu, press the ESC key. If the ESC key is pressed in the main menu, the RF powers screen is accessed. Figure 5: Hierarchical menu structure All menu items are described in detail below. 66 - RF Powers This is the main screen showing the RF powers of the amplifier: forward power, reflected power, unbalances, if any. For forward power a level bar is displayed. See an example in Figure 1. - Power Supply This screen shows all the signals coming from two power supply. To check the next (previous) power supply press the UP (DOWN) key. For each power supply, the voltage, the absorbed current and the status (ON or OFF) are shown. Figure 6: Power supply screen - Log/Alarms The control board is provided with an external EEPROM and a clock. Any alarm or switching event with the time at which it occurred is saved in the EEPROM. The Log/Alarms sub-menu allows to manage this log. It is possible to see the events stored in the log by selecting Log/Alarms View Log/Alarms. All events can be scrolled by pressing the UP and DOWN keys. For example, the event shown in Figure 7 is the turning on of the amplifier by means of the local switch. For every event/alarm a short description and the date and time at which it occurred is displayed. Figure 7: Event stored in the log 67 In case of alarm, the value of the measure which caused the alarm is saved into the log. In case of alarm still existing after five turning-on attempts, the parameter is marked as FAILED. Table 2 is the list of all the events which can be logged. EVENT DESCRIPTION Local ON Amplifier turned on by means of the local switch Local OFF Amplifier turned off by means of the local switch Remote ON Amplifier turned on remotely Remote OFF Amplifier turned off remotely Interlock open Interlock chain open Interlock closed Interlock chain closed Power Supply ON Power supply on Fwd Pwr xxxxW Alarm for forward power Ref Pwr xxxxW Alarm for reflected power UnbY xxxxW Unbalancing alarm V1 xx.xV Power supply voltage alarm I1 xx.xA Power supply current alarm Table 2: Events managed and logged by the control board The log may be completely deleted by selecting Log/Alarms Clear Log/Alarms. Amplifier can store in the log details about alarms and generic events. You can change this behaviour selecting Log/Alarms Log/Mode menu item. - Working Timer The control board has a working timer which is always enabled while the amplifier is working (i. e. there is at least one power supply working). The menu entry Working Timer View Timer allows to check the hours for which the timer has been enabled. Working Timer Timer Reset resets the timer. - Thresholds This is a screen showing the alarm threshold of each signals monitored by the control board. The list can be scrolled by means of the UP and DOWN keys. 68 - RMS/Peak The control board can monitor both the RMS and peak powers, the first used in digital systems. The menu entry Settings RMS/Peak allows to choose the power to be displayed and monitored. This menu is present only in certain amplifiers. - Date/Time This screen allows to set the current date and time. The setting is changed by pressing the arrow keys, then pressing the RET key to move to the following value and eventually save the changes. To go back to the previous menu and discard any change made, press the ESC key. Figure 8 shows an example of this screen. Figure 8: Date and time setting screen - Display The menu entry Settings Display allows to change some settings of the display, such has back light, contrast and screensaver. The back light and the contrast are set by means of the UP and DOWN arrow keys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. Figure 9 shows an example of this screen. With Settings Display Screensaver you can set an interval time after which display backlight is turned off. When display backlight is off, press any key to switch it on. Figure 9: Display contrast setting screen 69 - Frequency (only for some Amplifiers) The forward and reflected RF powers is measured by means of a directional coupler. In order to compensate for the effect due to the sampling made by the coupler, it is possible to set the frequency by menu entry Settings Frequency. The setting can be changed by pressing the arrow keys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. Set the video carrier frequency. - Slave Address The amplifier may be used either in stand-alone mode or as a slave of a master in a high power multiple units transmitter. In the latter case an unique address for each amplifier has to be specified, in order for all of them to communicate with the master on the same RS485 bus. The menu entry Settings Slave Address allows to choose the stand-alone mode or set a slave address by means of the UP and DOWN arrow keys. The changes made are saved by pressing the RET key or discarded pressing the ESC key. An example of this screen is shown in Figure 10. Figure 10:Slave address setting screen - Remote The amplifier may be controlled either locally, by means of the keys and display, or remotely. There are three possibilities for remote control: - using a direct serial connection between amplifier RS232 connector and a PC RS232; - using the remote control device manufactured by Elettronika S.r.l. (RCU), on the RS485; - using a general-purpose control system connected to telemeasures. You can enable / disable remote control choosing menu item Settings Remote. When remote control is enabled, the yellow REMOTE LED on the front panel is lit. - Interlock One of the pins of the telemeasure connector, located on the rear panel, is used for the interlock alarm. It is an input line which turns off the amplifier in case of alarm. The interlock check can be enabled or disabled using 70 menu item Settings Interlock. When it is enabled, the status bar shows the lock symbol (see Figure 3), which is close if the interlock chain is closed (no alarm) or open if it is open (alarm). - Firmware Release The menu entry Settings Firmware Release allows to display the firmware version number and the hardware release of the amplifier. - Serial Number The menu entry Settings Serial Number allows to display the serial number of the apparatus. 71 This page is intentionally blank 72
