KK da LO i Jw DI te LI Pi1 5 4 k wi Figure 1 Asynchronous Communications Bit Diagram This special bit is called the parity bit Parity is a simple method of determining if a data bit has been lost or corrupted during transmission There are several methods for implementing a parity check to guard against data corruption Common methods are called E ven Parity or O dd Parity Sometimes parity is not used to detect errors on the data stream This is refereed to as N o parity Because each bit in asynchronous communications is sent consecutively it is easy to generalize asynchronous communications by stating that each character is wrapped framed by pre defined bits to mark the beginning and end of the serial transmission of the character The data rate and communication parameters for asynchronous communications have to be the same at both the transmitting and receiving ends The communication parameters are baud rate parity number of data bits per character and stop bits i e 9600 N 8 1 Sealevel Systems COMM 850 PCI Page 9 Appendix E Silk Screen Appendix E Silk Screen 4 90 60 2 D KA oF oe 7104 Made in USA C7 RI R4 EE BB es R2 R5 BB es EBBBEBBEBEE CB R6 BSE BBa R3_R7 Se ZE 160850 CASI EBBE BABE HEB C6 a 0000 B B000 a D i CE U4geaaaaa Go USggegees p _BEBBABB EBEBBBE a R9 013 ET LV VE EE SEE
