When this value is specified as the DA_Field value then DA_Method,

 

DA_Bytcnt, DA_Offset, DA_Elecnt must also be specfied.

 

Appendix B.4. DA_Method Parameter Values and Notes

The DA_Method specifies a method for interpreting a range of bytes when the DA_Field=special.

Method #

Description

 

Each byte is valid when it contains only one of the following ASCII characters.

 

{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F }

Method 1:

Each byte being parsed is considered to be a hexadecimal digit with the most

significant digit being the left-most byte.

 

 

The four bytes 30 31 32 33 (hex) are therefore interpreted as the hexadecimal

 

number 0123 and the decimal value is equal to 291.

Method 2

As method 1, but used for humidity's and temperatures which are transmitted as the

number of tenths of a unit – Thus the 4 bytes yield the decimal number 29.1 °F/%.

 

 

Each byte is regarded as containing a hexadecimal digit in ASCII format.

 

Example: incoming byte contains 41(hex). -> regarded as the hexadecimal digit 'A' in

Method 3

ASCII format.

 

The hex digit is converted to a series of 8 bits. In this example the bits are 00001010

 

with the msb being the left-most.

Method 4

As Method 3 except that the decimal value of this digit is written to the Data Array. In

this example the number 10 would be written to the Data Array.

 

Method 5

There is no translation - the raw bytes are written to the data array.

 

Processes an array of elements using method 1 translation. The raw data being

Method 6

parsed is considered to consist of DA_elecnt elements each consisting of DA_bytecnt

 

bytes.
