9. Camera Control Command Protocol
(For RS-232, RS-422, and RS-485)
9.1 Communication Format
The communication data format from PC to Camera
Data of total 6 bytes is transmitted from PC to camera.
Format:
Byte1 Byte2 Byte3 Byte4 Byte5 Byte6
0xC5 Code1 Code2 Code3 CAM_ID C.S.
Description: (Refer to 9.2 PC Command)
(a) Byte 1: Camera realizes the protocol comes from the PC.
(b) Byte 2: The data is changeable according to the PC Command.
(c) Byte 3: The data is changeable according to the PC Command.
(d) Byte 4: The data is changeable according to the PC Command.
(e) Byte 5: Camera’s ID (Identification) number to communicate (0 ~ 255).
It will be impossible to communicate when there’s a difference between the
value of CAM_ID and the given value of the Camera’s ID.
(f) Byte 6: The value of Check Sum from ‘Byte 1’ to ‘Byte 5’.
Ex.: In case of transmission, ‘0xC5, 0x5F, 0x0C, 0x00, 0x00‘
0xC5 + 0x5F + 0x0C + 0x00 + 0x00 = 0x130
Therefore, C.S. = 0x30
