3. 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 8 cPCI Page 10 Appendix E Silk Screen Appendix E Silk Screen D l LUT LITU LITU LTC T l NET NTT NETU NETII i 0 i i i l WI WU BURITI Il il Tz i 12 LETNI NTT penne II D Ds II I CO m M m m U DODDODDOOOOOOO00000000D00ODDOOOOO0 0000000000 IS 1 T D ns 0 DONOS DRGOGOON GOO GODOAB ROB AOOOGO 0000000000 i T l 1 0 o 0 1z 1 I lo 1 AM DD 1 o WA RUN DUNN 1 Ie pe Sealevel Systems COMM 8
