Code
Data
cks
CR
Address:
3 Bytes, decimal
Code:
1 Byte, command parameter, upper case character for read
command, lower case character for write command
Data:
data field, max. 6 Bytes; can be absent depending on code
cks:
1 Byte, checksum, defined as sum over all ASCII codes of the fields
address, code and data, modulo 64 plus 64.
CR:
Carriage Return (0Dh, 13d)
Data Formats:
BOOLEAN
1 Byte
STRING:
max. 6 Bytes
UNSIGNED INT:
6 Bytes with leading zeros
FLOAT:
6 Bytes, exponential format
4 Bytes mantissa (means mantissa value x 1000)
2 Bytes exponent, offset 20
FLOAT-values are transmitted in hPa (mbar)!
Example: Value "460016" in a float type data field means 4.6x10
-4
mbar.
Interface-Parameters:
9600 baud, 8 data bits, 1 stopbit, no parity
