87Picture 1: Simplified block diagram of the control and display boardCONTROL BOARD AND DISPLAY SCH0223AR1DESCRIPTIONThe control board SCH0223AR1 manages the operational logic of the amplifier: switching on and off, powersupply and fans, alarms and protections, remote control, human-machine interface. There are managed by amodern and powerful 16 bit micro-controller (MB90F543), made by Fujitsu, which is the main part of theboard.Picture 1 shows the block diagram.
88It can be seen that the micro-controller is the heart of the control system, to which the various peripherals(power supply, serial ports, telemeasure socket, AGC port, RF amplifier module, ROM, clock, display andkeys) are interfaced.- Power SupplyThe board is powered with a continuous +24V voltage from which the +5V voltage powering the most of thechips (micro-controller, operational amplifiers, display, etc.) is derived by means of a switching converter (seeIC19). A +12Vdc voltage is obtained from it as well, by means of a linear conversion provided by theintegrated circuit IC8. From this, a -12Vdc voltage is obtained by means of the integrated circuit IC5. The-12V voltage is also used to adjust the contrast of the display.- ConnectorsOn the board SCH0223AR1 there are several connectors used as interfaces for the peripherals of the apparatusand the ports for external communication.POWER SUPPLYThe connectors J1, J6, J8 e J12 are connected to the power supply powering the RF amplifier modules. Thenumber of power supply used changes depending on the amplifier, up to four power supply. They are connectedin the order shown in Table 1 below. Remaining connectors, if any, are left unused.Table 1: Interface connectors for the power supplyThrough this connection, each power supply provides the two levels of voltage and current acquired by themicro-controller by means of an internal ADC. Besides the connectors allow the control board to turn on oroff the individual power supply (for instance when an alarm occurs). The used power supply are protectedCONNECTOR POWER SUPPLY N°J1 1J6 2J8 3J12 4
89agaimst voltage surges or temperature increases. If one of these events occurs, the power supply is switchedoff and the event is signalled to the micro-controller through the connection with the control board.RF AMPLIFICATIONThe J3 connector interfaces the control board with the RF amplification section. Through this connector themicro-controller acquires the sample of forward and reflected power, unbalancing (if any), and temperatureof the critic amplification area. It also allows to inhibit the transistors in case of reflected power alarm, bymeans of a totally hardware, thus extremely fast protection.Depending on the apparatus, this connector may also allow to enable or disable the cooling fans of the criticarea.RS485The J11 connector (10 pin socket) is directly wired to a DB9 female connector placed on the rear panel of theapparatus. This communication bus allows to connect the amplifier to the control (Amplifier Control) moduleof a high-power transmitter composed by several individual amplifiers. In this case, each amplifier and theAmplifier Control are connected to the same 4-wires RS485 bus and each of them as a unique address(which can be set by means of the keys and the display) for correct communication.In case of single (stand-alone) amplifier, the RS485 connector can be used for connection to the RemoteControl Unit (RCU) made by Elettronika S.r.l. This unit allows to monitor and control the remote transmitterfrom any site provided with PSTN or GSM1 phone connection.Table 2 shows the wiring between the J11 connector on the board and the DB9 female connector on the rearpanel, along with the description of the lines.1 For more details about the control system contact the distributor or the manufacturer.PIN N°ON DB9PIN N°ON J11 DESCRIPTION11 Not used23 Rx-35 Rx+47 +5V59 GND62 Not used74 Tx-86 Tx+98 Not usedTable 2: Description of the RS485 connector
90TELEMEASURESThe J9 telemeasure connector (10 pins socket) is directly wired on a DB9 female connector placed on therear panel. There are input and output digital lines (TTL level) and analog output lines on this connector, whichare used to monitor and control the amplifier by means of a general-purpose remote control system.The correspondende between the pins of the J9 connector on the board and the DB9 female connector on therear panel, as well as the meaning of the various lines, is shown in table 3 below (the directions refers to theposition of the micro-controller on the board).PIN N°ON DB9PIN N°ON J9 TYPE DIRECTION DESCRIPTION1 1 Analog Output Forward power2 3 Analog Output Reflected power3 5 Analog Output Temperature4 7 Digital InputInterlock:0V = Interlock Alarm5V = Normal59 - -Ground6-7 2-4 Digital Output Free Contact(closed when amplifier is in alarm)8 6 Digital Input Turning-on control(usually high, active when low)9 8 Digital Input Turning-off control(usually high, active when low)Table 3: Description of the telemeasures connectorThe input stage of the digital controls has an internal pull-up towards the 5V power supply voltage. To use thislines it only takes setting a switch to close to earth, when closed, the relevant control (turning on or off) isenabled and the switch may be switched open again (impulse controls).The interlock pin may be used as protection so that the amplifier is switched off the digital input level is low. Itis possible to use several serially connected switches to make an interlock chain. Usually all switches areclosed and the interlock level is low, thus the amplifier is on. If even only one of the switches is opened, the(*)(*)(*) You can select by means of two jumpers on the board (JP1 and JP2) RMS or peak power. If there are two jumpers on pins 1 and 2 ofJP1 and JP2 connector, RMS power is selected. Otherwise, if there are two jumpers on pins 2 and 3 of the same connectors, peak poweris selected.
91Picture 2: Usage of the digital input signals of the telemeasures connectorAGC / EXCITERThe connector called J10, as the telemeasures connector and the RS485 bus, is wired to a DB9 femaleconnector placed on the rear panel of the amplifier. This connectors allow the implementation of an automaticgain control between an exciter and the amplifier. A voltage signal related to the forward output powersupplied by the amplifier is provided through two pins of the AGC connector. Connecting one of these to therelevant input pin of the exciter, this can pursuit a given voltage level, so that the output power is alwaysconstant. In order to avoid that, in case of an alarm decreasing the forward power, the exciter stronglyincreases the output level due to the AGC, thus damaging the amplification stages, the connector is providedwith two digital output lines called AGC Alarm. Under alarm conditions, this lines are brought by the micro-controller at a low level, so that the exciter can stop the AGC.Table 4 shows the connection between the J10 connector on the board and the DB9 connector on the rearpanel, along with the description of each pin (the direction of the pin is referred to the position of the micro-controller on the board).level of the interlock signal becomes high (this line has a pull-up towards the +5V power supply voltage aswell) and the protection for interlock alarm is activated for the amplifier, which is switched off. Note that incase the interlock protection is not used, the pin 4 of the DB9 telemeasure connector and the earth pin (pin 5)must be short circuited. Otherwise it is possible to disable the monitoring of the interlock chain from menu (seeuser manual).Picure 2 shows a usage for the digital input signals to turn on and off the amplifier and for the interlock alarm.
92Table 4: Description of the AGC connectorRS232The DB9 female connector on the front panel is an external communication RS232 serial port, through whicha PC can be connected directly to the amplifier in order to perform operations such as the remote control (bymeans of an adequate software2) and the update of the microcontroller firmware.The used communication protocol is asynchronous, at a 19200bps speed, 1 start bit, 8 data bits, 1 stop bit,no parity. No hardware flow is used. The connector is DCE type and the pin used are shown in Table 5.PIN N° ON DB9 123456789DESCRIPTION -TxDRxD-GND----MISCELLANEOUSThe J2 (called AUX), J4, J5 and J17 connectors are not used and are there only for future updates. The SW1dip-switches are partially used for the configuration of the correct mode for the micro-controller. The otherswitches are not used. It is important that the position of the dip-switches is left unchanged, because changingit may set a wrong mode for the micro-controller, affecting the work of the whole amplifier.2 For more information about this application contact the distributor of the manufacturer.PIN N°ON DB9PIN N°ON J10 TYPE DIRECTION DESCRIPTION11- -Ground23DigitalOutputAGC Alarm0V = Alarm5V = Normal35DigitalOutputAGC Alarm0V = Alarm5V = Normal47- -Not used59 - -Not used62 - -Not used7 4 - - Nout used8 6 Analog Output Forward power9 8 Analog Output Forward powerTable 5: Description of the RS232 connector
93FIRMWARE UPDATEThe micro-controller MB90F543 is provided with a built-in Flash memory containing the firmware. Thefirmware can be updated to later versions without removing the apparatus from the rack and/or replacing thechip.To upgrade it, connect a PC to the RS232 socket on the front panel of the apparatus by means of a cableDB9 male - DB9 female (pin-to-pin).Launch on the PC the EKAFlash application, select the serial port in use of the PC and choose the update fileby pressing the ... key and click on Download button.Eventually, turn off the amplifier from the main switch and then turn it on again. The upgrade of the firmwarebegins on the EKAFlash window. Picture 3 shows this window while a firmware is being updated.Picture 3: The EKAFlash window while updating a firmware
