2. SERıAL COMMUNıCATıON 1) Serial communication is common method of transmitting data between a computer and a peripheral device such as a programmable instrument or even another computer. 2) Serial communication transmits data one bit at a time, sequentially, over a single communication line to a receiver. Serial communication used by many devices for instrumentation; numerous GPIB-compatible devices also come with an RS-232 based port. This method is used when data transfer rates are very low or the data must be transferred over long distances 3) Serial communication is popular because most computers have one or more serial ports, so no extra hardware is needed other than a cable to connect the instrument to the computer or two computers together.

3. HOW DOES SERıAL COMMUNıCATON WORKS Serial communication requires that you specify the following five parameters: 1) The speed or baud rate of the transmission 2) The number of data bits encoding a character 3) The sense of the optional parity bit (whether to be used or not, if yes then odd or even) 4) The number of stop bits 5) Full or half-duplex operation

4. SERıAL COMMUNıCATıON STANDARTS 1) RS-232 // Msp430 includes RS-232 2) RS-423 3) RS-485 4) USB 5) Fire Wire 6) Ethernet 7) MIDI 8) PCI Express 9) SPI & SCI 10) IIC 11) IrDA
