*C.S.
*C.S. = Check Sum

•
The data of total 6 bytes is transmitted from the exter-
nal RS-485 device to the camera.
•
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
C.S. = 0xC5 +0x5F +0x02 +0x00 +0x0A = 0x0130
therefore, C.S. = 0x30
