Connecting RS-485 Device

Use these ports to connect an external device of RS-485

format.

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

BYTE1 BYTE2 BYTE3

0xE5 0x86 Camera ID

BYTE4 BYTE5 BYTE6

CODE1 CODE2 *C.S.

*C.S. = Check Sum

• The data of total 6 bytes is transmitted from the

external 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
