The each byte in RTU mode  has  following format:

8-bit binary, hexadecimal 0-9, A-F

2 hexadecimal characters contained in each 8-bit eld of 
the message

4 bytes (32 bits) per parameter.

Floating point format ( to IEEE 754)
Most signicant byte rst (Alternative  least signicant byte rst)

Format of Data Bytes

2 byte Cyclical Redundancy Check (CRC)

Error Checking Bytes

1 start bit,
8 data bits, least signicant bit sent rst
1 bit for even/odd parity
1 stop bit if parity is used; 1 or 2 bits if no parity

Byte format

Communication Baud Rate is user selectable from the  front panel  between  2400, 4800, 
9600, 19200 bps.

Exception Cases : An exception  code will be generated when  the
