| CR001B-K4-2 Output Data Structure – ASCII(RS232.TTL)9600,N,8,1 STX (02H) | DATA(10 ASCII) | CHECK SUM (2 ASCII) | CR | LF | ETX (03H) |
[The 1byte (2 ASCII charaters) Check sum is the “Exclusive OR” of the 5 hex bytes(10 ASCII) Data characters.] For Example:DATA : 62H E3H 08H 6CH EDH, Check Sum: (62H) XOR (E3H) XOR (08H) XOR (6CH) XOR (EDH)=08H, Output: 0X02 0X36 0X32 0X45 0X33 0X30 0X38 0X36 0X43 0X45 0X440X0D 0X0A 0X03 |
