CONTROL BOARD AND DISPLAY SCH0223AR1
DESCRIPTION
The control board SCH0223AR1 manages the operational logic of the amplifier: switching on and off, power
supply and fans, alarms and protections, remote control, human-machine interface. There are managed by a
modern and powerful 16 bit micro-controller (MB90F543), made by Fujitsu, which is the main part of the
board.
Picture 1 shows the block diagram.
88
It 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 and
keys) are interfaced.
- Power Supply
The board is powered with a continuous +24V voltage from which the +5V voltage powering the most of the
chips (micro-controller, operational amplifiers, display, etc.) is derived by means of a switching converter (see
IC19). A +12Vdc voltage is obtained from it as well, by means of a linear conversion provided by the
integrated 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.
- Connectors
On the board SCH0223AR1 there are several connectors used as interfaces for the peripherals of the apparatus
and the ports for external communication.
POWER SUPPLY
The connectors J1, J6, J8 e J12 are connected to the power supply powering the RF amplifier modules. The
number of power supply used changes depending on the amplifier, up to four power supply. They are connected
in the order shown in Table 1 below. Remaining connectors, if any, are left unused.
Table 1: Interface connectors for the power supply
Through this connection, each power supply provides the two levels of voltage and current acquired by the
micro-controller by means of an internal ADC. Besides the connectors allow the control board to turn on or
off the individual power supply (for instance when an alarm occurs). The used power supply are protected

agaimst voltage surges or temperature increases. If one of these events occurs, the power supply is switched
off and the event is signalled to the micro-controller through the connection with the control board.
RF AMPLIFICATION
The J3 connector interfaces the control board with the RF amplification section. Through this connector the
micro-controller acquires the sample of forward and reflected power, unbalancing (if any), and temperature
of the critic amplification area. It also allows to inhibit the transistors in case of reflected power alarm, by
means 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 critic
area.
RS485
The J11 connector (10 pin socket) is directly wired to a DB9 female connector placed on the rear panel of the
apparatus. This communication bus allows to connect the amplifier to the control (Amplifier Control) module
of a high-power transmitter composed by several individual amplifiers. In this case, each amplifier and the
Amplifier 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 Remote
Control Unit (RCU) made by Elettronika S.r.l. This unit allows to monitor and control the remote transmitter
from 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 rear
panel, along with the description of the lines.

TELEMEASURES
The J9 telemeasure connector (10 pins socket) is directly wired on a DB9 female connector placed on the
rear panel. There are input and output digital lines (TTL level) and analog output lines on this connector, which
are 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 the
rear panel, as well as the meaning of the various lines, is shown in table 3 below (the directions refers to the
position of the micro-controller on the board).

Table 3: Description of the telemeasures connector
The input stage of the digital controls has an internal pull-up towards the 5V power supply voltage. To use this
lines it only takes setting a switch to close to earth, when closed, the relevant control (turning on or off) is
enabled 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. It
is possible to use several serially connected switches to make an interlock chain. Usually all switches are
closed 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 of
JP1 and JP2 connector, RMS power is selected. Otherwise, if there are two jumpers on pins 2 and 3 of the same connectors, peak power
is selected.

Picture 2: Usage of the digital input signals of the telemeasures connector
AGC / EXCITER
The connector called J10, as the telemeasures connector and the RS485 bus, is wired to a DB9 female
connector placed on the rear panel of the amplifier. This connectors allow the implementation of an automatic
gain control between an exciter and the amplifier. A voltage signal related to the forward output power
supplied by the amplifier is provided through two pins of the AGC connector. Connecting one of these to the
relevant input pin of the exciter, this can pursuit a given voltage level, so that the output power is always
constant. In order to avoid that, in case of an alarm decreasing the forward power, the exciter strongly
increases the output level due to the AGC, thus damaging the amplification stages, the connector is provided
with 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 rear
panel, 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 as
well) and the protection for interlock alarm is activated for the amplifier, which is switched off. Note that in
case 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 (see
user manual).
Picure 2 shows a usage for the digital input signals to turn on and off the amplifier and for the interlock alarm.

Table 4: Description of the AGC connector
RS232
The DB9 female connector on the front panel is an external communication RS232 serial port, through which
a PC can be connected directly to the amplifier in order to perform operations such as the remote control (by
means 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.

MISCELLANEOUS
The J2 (called AUX), J4, J5 and J17 connectors are not used and are there only for future updates. The SW1
dip-switches are partially used for the configuration of the correct mode for the micro-controller. The other
switches are not used. It is important that the position of the dip-switches is left unchanged, because changing
it may set a wrong mode for the micro-controller, affecting the work of the whole amplifier.

FIRMWARE UPDATE
The micro-controller MB90F543 is provided with a built-in Flash memory containing the firmware. The
firmware can be updated to later versions without removing the apparatus from the rack and/or replacing the
chip.
To upgrade it, connect a PC to the RS232 socket on the front panel of the apparatus by means of a cable
DB9 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 file
by 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 firmware
begins on the EKAFlash window. Picture 3 shows this window while a firmware is being updated.
