• When the BO flag is “0,” the MSB is output first. When the BO flag is “1,” the LSB is output
first.
• If the check sum is enabled (parameter = 1) using the CS command parameter, each sum
value is inserted in the header sum and data sum sections in the “Conceptual Diagram” on the
previous page. If the check sum is disabled (parameter = 0), a zero is inserted in the header
sum and data sum sections. For a sample program that calculates the sum value, see
“Calculating the Sum Value” on the next page.
• If the amount of data output in response to a ME, MI, or MO command is large, not all the data
may be returned in one output request (parameter GET). In this case the END flag becomes
“0.” You must send output requests (parameter NEXT) to receive the rest of the data until the
END flag becomes “1.”
• The bits that have “–” for the name and flag are not used. The value is undefined.

• The table above shows the different types of BINARY Data.
• BINARY data comes in two types, data and file.
• Data
• Measured/computed data can be output using the FD command.
• FIFO data can be output using the FF command.
• Display data or event data can be output using the MI command.
• The data format is disclosed. See section 7.3.
• File
• Display data, event data, TLOG data, and setup data files can be used on the
DAQSTANDARD software that came with the package. For details, see the
DAQSTANDARD software manual (IM04L31A01-61E).
• Files that are in common formats can be opened using software programs that are sold
commercially.
• Other formats are written in ASCII code. A text editor can be used to open these types of
files.
• The identifier section in the “Conceptual Diagram” on the previous page contains the ID
number that indicates the BINARY Data type.
Note
BINARY data that are not indicated in the above table are considered undefined files.
