INTRODUCTION TO BHARAT ELECTRONICS LIMITED PROJECT REPORT ABOUT COMBAT MANAGEMENT SYSTEM BLOCK DIAGRAMS OF CMS TEST PLAN FOR MMIC CONCLUSION
BHARAT ELECTRONICS LIMITEDINTRODUCTION
Bharat Electronics Limited (BEL) was established in 1954 as a Public Sector Enterprise under the administrative control of Ministry of Defense as the fountainhead to manufacture and supply electronics components and equipment. BEL, with a noteworthy history of pioneering achievements, has met the requirement of state-of-art professional electronic equipment for Defense, broadcasting, civil Defense and telecommunications as well as the component requirement of entertainment and medical X-ray industry. Over the years, BEL has grown to a multi-product, multi-unit, and technology driven company with track record of a profit earning PSU. The company has a unique position in India of having dealt with all the generations of electronic component and equipment. Having started with a HF receiver in collaboration with T-CSF of France, the company's equipment designs have had a long voyage through the hybrid, solid state discrete component to the state of art integrated circuit technology.
BEL was among the first Indian companies to manufacture computer parts and peripherals under arrangement with International Computers India Limited (ICIL) in 1970s.

Test plan for MMIC
MMIC is a part of DMFC used in Combat Management System. MMIC which stands for man machine interface card is an important tool for establishing effective communication between different parts of the system on - board ship and also various controls. To develop a test software for the testing of the MMIC card of the CMS 17 using assembly language programming of 87C51 microcontroller and C programming.
Basic Aim of The Project
Approach to test the MMIC
Using Assembly Language Programming Test program for effective chip select for suitable LED indication To establish communication between ADC and PPI for obtaining bearing and gain To test the serial port communication
Using C Programming
To send the data to serial port COMPORT for effective LED indication and check for loop back the data using serial port. Also create features for further additions in future.
