Protocol mode:
Settings:
1 = Slave Addr = 0
2 = Baudrate = 400000
3 = Data Control =
P
4 = Data Poll*10ms = 10
5 = Flow Control = N
Using this setting it will be possible to directly access the interface via TCP/IP and to directly address the
I2C-Slave by means of corresponding commands such as WRITE and READ.
WRITE: 0x02,0x00,0x0A,0x03,0x50,0x02,0x00,0x00,0x57,0x00,0x01,0xnn,0x03
0x02 STX
0x00,0x0A Len (10 Bytes) follows
always 2 Byte
0x03 function code (with all messages)
0x50 Slave Address
0x02 Count Internal Address
0x00,0x00 Internal Address 0x00,0x00
Count(0-4 Byte)
0x57 W = WRITE
0x00,0x01 write 1 byte
always 2 Byte
0xnn Byte to write
0x03 ETX
READ: 0x02,0x00,0x09,0x03,0x50,0x02,0x00,0x00,0x52,0x00,0x02,0x03
0x02 STX
0x00,0x09 Len (9 Bytes) follows
always 2 Byte
0x03 function code (with all messages)
0x50 Slave Address
0x02 Count Internal Address
0x00,0x00 Internal Address 0x00,0x00 Count(0-4 Byte)
0x52 R = READ
0x00,0x02 read 2 byte
always 2 Byte
0x03 ETX
MSG : no ACK/NAK (function code = 0x00)
NAK only (function code = 0x01)
ACK only (function code = 0x02)
ACK and NAK (function code = 0x03)
