CAN (Controller Area Network) is a communication standard primarily intended for use in automotive industry. It enables the
microcontroller to communicate to a car device without using a host PC. In addition, such communication is widely used in industrial
automation. The MCP2551 circuit is used for communication between the CAN controller (MCP2510) and the taget device. The
MCP2510 circuit is a stand-alone CAN controller which communicates to the microcontroller using SPI communication. To enable
connection between the microcontroller and MCP2510, it is necessary to set switches 6, 7 and 8 on the DIP switch SW2 as well as
switches 4, 5 and 6 on the DIP switch SW4 to the ON position.

USART (8QLYHUVDO6\QFKURQRXV$V\QFKURQRXV5HFHLYHU7UDQVPLWWHU) is one of the most common ways of exchanging data between
the PC and peripheral units. The RS232 serial communication is performed through a 9-pin SUB-D connector and the microcontroller
USART module. The UNI-DS3 provides one RS232A port. Use switches marked as RX232A and TX232A as well as RX232B and
TX232B on the DIP switch SW3 to enable port RS232A. The microcontroller pins used in such communication are marked as follows:
RX - UHFHLYHGDWDOLQH and TX -WUDQVPLWGDWDOLQH. Data rate goes up to 115 kbps.
In order to enable the microcontroller’s USART module to receive input signals which meet the RS232 standard, it is necessary to
adjust voltage levels using an IC circuit such as MAX232.
)LJXUH: RS232 module and microcontroller connection schematic
As mentioned above, the UNI-DS3 development system is a
universal tool which makes it suitable for use with different
microcontrollers. The position of pins used for RS232
communication is not the same for all microcontrollers. In
order to enable different microcontrollers to make advantage
of RS232 communication it is necessary to select appropriate
microcontroller pins to be used for such communication. DIP
switch SW3 is used as a communication line selector.
The method of connecting the RS232 communication module
depends on the MCU card placed into the DIMM-168P socket.
All MCU cards are described at the end of this manual and it is
clearly stated which pins are used for RS232 communication
with microcontrollers. For example, for the 8051 MCU card,
switches 5 (RX232A) and 6 (TX232A) on the DIP switch
SW3 are used. For the ATmega128 MCU card, switches 5,
6, 7 and 8 on the DIP switch SW3 may be used. Which of
these four pins are to be used here depends on which pins
on the ATmega128 microcontroller you want to use for RS232
communication. In case pins RE0 and RE1 are used, switches
5 (RX232A) and 6 (TX232A) on the DIP switch SW3 should be
set to the ON position. In case pins RD2 and RD3 are used,
switches 7 (RX232B) and 8 (TX232B) on the DIP switch SW3
should be set to the ON position.

communication standard is the ability to exchange data between distant points (up to 1200 m) and high tolerance to accompanying noise.
The UNI-DS3 development system features a connector used for connecting devices which use RS485 communication. The LTC485

The MMC/SD connector is used to enable memory cards to be interfaced with the microcontroller. To enable communication between
memory card and microcontroller, it is necessary to adjust their voltage levels. Memory card is powered by the 3.3V power supply
voltage (VCC3) generated by the REG2 voltage regulator, whereas the microcontroller’s power supply voltage is 5V (VCC). In case
the MCU card is powered with 5V power supply voltage, it is necessary to remove jumpers J17, J18 and J19. As a result, resistors
start acting as a voltage dividers. In this case, such divider is used to lower the microcontroller’s power supply voltage from 5V to
3.3V. To enable communication between microcontroller and memory card, switches 4, 5 and 6 on the DIP switch SW4 should be
set to the ON position.

A digital-to-analog converter is a module used to convert a digital code into an analog voltage signal. The UNI-DS3 development
system is equipped with the MCP4921 circuit which acts as a 12-bit digital-to-analog converter. This circuit provides a high accuracy
of conversion as well as a high-quality signal despite noises occuring when it is used in industrial applications. It communicates with
the microcontroller via SPI serial communication. In order to establish connection between these two circuits, it is necessary to set
switches 3 and 4 on the DIP switch SW3 to the ON position. It is also necessary to enable serial communication by setting switches 4
and 6 on the DIP switch SW4 to the ON position.
The function of jumper J15 is to determine voltage reference to be used in digital-to-analog conversion. By setting jumper to the 4.096
position, the MCP4921 circuit will be powered with the 4.096V voltage. By setting jumper J15 to the VCC position, the MCP4921 circuit
will be powered with the 5V power supply voltage.

An A/D converter is used for converting an analog signal into the appropriate digital value. A/D converter is linear, which means that
converted number is linearly dependent on the input voltage value. The MCP3204 circuit is used as an A/D converter on the UNI-DS3
development system. Voltage to be converted is brought to the A/D converter input pins which converts it into a 12-bit number. The
result of conversion is transferred to the microcontroller by means of serial communication. To make this transmission possible, it is
necessary to set switch 2 on the DIP switch SW3 as well as switches 4, 5 and 6 on the DIP switch SW4 to the ON position.
A voltage reference supplied on the Vref pin of the MCP3204 circuit is used to determine maximum input analog signal, whereas jumper
J15 is used to determine this voltage reference. When jumper J15 is in the 4.096 position, the 4.096V voltage is used as a voltage
reference. Otherwise, when jumper J15 is in the VCC position, then the 5V power supply voltage is used as a voltage reference.
