[:DATA] <type>[,length]

This command specifies the data format

Usage

:FORMat[:DATA] <type>[,<length>]

[:DATA]?

<type>

 ASCii: ASCII format

 REAL: IEEE754 single precision format

 REAL: IEEE754 double precision format

 SREal: IEEE754 single precision format

 DREal: IEEE754 double precision format

32 or 64; optional for REAL; default 32, single precision format

Details

When using the ASCII, SREal, or DREal parameter, a <length> parameter is not required.

This command is used to select the data format for transferring readings over the bus. For every

reading conversion, the data string sent over the bus contains the elements specified by the

:ELEMents command. The specified elements are sent in a particular order.

The ASCII data format is in a direct readable form for the operator. Most BASIC languages easily

convert ASCII mantissa and exponent to other formats. However, some speed is compromised to

accommodate the conversion. The figure below shows the ASCII format that includes all the data

elements.
