another value for DA_Assoc.

 

 

 

 

 

 

 

 

Da_Freq

Used only for connection to

 

 

 

 

DART’s.

 

 

 

 

Specify in milliseconds the

 

 

 

 

interval at which you want a

 

 

 

 

wrbc/rdbc map descriptor to be

 

 

 

 

executed.

 

 

 

 

When using wrbc/rdbc’s to a

 

 

 

 

dart device set the scan interval

 

 

 

 

to 5.0s and set this parameter to

 

 

 

 

a number greater than 180000

 

 

 

 

(3 minutes). An interval of

 

 

 

 

300000 (5 minutes is

 

 

 

 

recommended).

 

 

 

 

 

 

 

 

DA_MethodΨ

Specifies the extraction method.

See section 6.3 for a list of

 

 

 

Such as Hex-ASCII to decimal

possible values.

 

 

 

number in 10's of a degree,

 

 

 

DA_BytcntΨ

Specifies the number of bytes

>= 1

 

 

 

that are to be processed by the

 

 

 

 

method specified above. For

 

 

 

 

method#6 which processes an

 

 

 

 

array of elements the

 

 

 

 

DA_Bytcnt specifies the

 

 

 

 

number of bytes that constitute

 

 

 

 

each element of the array.

 

 

 

DA_OffsetΨ

composite that is returned when

composite. No validation is

 

 

 

the slave is polled. The offset is

performed.

 

 

 

the number of bytes from the

 

 

 

 

first data byte.

 

 

 

 

 

 

 

 

DA_ElecntΨ

Number of elements that are

>= 1

 

 

 

produces by the extraction

 

 

 

 

method.
