UNITED ELECTROTECHNOLOGIES
DATA COMMUNICATION CONCEPT TRAINER (DCCT)
Communication systems have very much evolved to become an integral part of life. Equipments like Mobile phones and systems like GPS are no more considered luxuries but have become basic necessities. Thanks for the data communication systems, that have shrunk the earth, thereby providing access to anyone & anything to any corner of the world.
Having such a situation, wherein the presence of the data communication systems is very much felt in every aspect of life, there arises a strong need for the upcoming engineers to excel in the basics & concepts of data communication.
To address the need of the time, here is United Electrotechnologies, with all its expertise & enormous exposure of the real world of technology and in an effort of sharing its experience with the young engineers presents, the Data Communication Concept Trainer (DCCT) system. The DCCT system excels in its simple, user-friendly & self-explanative way of teaching the basic concepts in a practical way.
UE-DCCT System Set-up
MCS51 based Controller Card
Keyboard Controller using 8279
Serial Communication using 80C51’s in built UART
RS 232 Communication port for 8051 UART using MAX-232
RS 485 Communication port for 8051 UART using 75174 and 75175
Display 20*4=80 Character LCD.
Bus Expansion Standard address, data, Control signals, interrupts and extra chip selects using 60-Pin male FRC Connector (P4)
Downloading Hex codes from the PC into the memory (NVRAM)
Implementation with simple Embedded Systems for ease of understanding
Memory - EPROM of 32K - Static RAM of 32K - NVRAM of size 8K
Add on Card – Communication Module
Serial Communication – using Two 8251 USART’s
Parallel Communication – using Intel 8255
Programmable Internal Timer – using Intel 8254
RS232 Communication port for 8251 USART using MAX-232
Analog Modulation and Demodulation unit using FSK technique XR2206/ XR2211
Fiber Optic Interface using FO TX and RX modules
This environment allows the students to use the H/W for learning the MCS-51 series Microcontroller programming by downloading the example programs through the serial port & executing them. The same features also allow the H/W to be used in academic projects.
