RS-485 Protocol
Data Communication Format
•Data Length: 1 Byte (8 Bit)
•Start/Stop Bit: 1 BIT
•Parity Bit: None
•Baud rate: 9,600 bps
Format
BYTE 1 BYTE 2 BYTE 3 BYTE 4 BYTE 5 BYTE 6
0xC5 CODE1 CODE2 CODE3 CAM_ID *C.S.
*C.S. = Check Sum
•The data of total 6 bytes is transmitted from the external
•BYTE 6 : The value of Check Sum from ‘BYTE 1 ’ to ‘BYTE 5 ’.
ex) In case of transmission, 0xC5, 0x5F, 0x02, 0x00, 0x0A”
C.S. = 0xC5 +0x5F +0x02 +0x00 +0x0A = 0x0130 therefore, C.S. = 0x30
