Data Transfer to Computer
Figure 5-8 Data Transferred in TDF M Format
See Table 5-1 on page 304 for an example of how data is sent to the
computer using the TDF M format.
TDF B (B-Format): Return Binary Numbers in Measurement
Units (output only)
The binary (B) format transmits data in measurement units, as binary
numbers. This format provides the fastest data transfer and requires
the least amount of memory to store data. Each data point is
transferred in binary as two 8-bit bytes; the most significant byte is
sent first, followed by the least significant byte. Binary data can also be
easily converted into measurement data. If speed and memory are
important considerations, you may prefer B-format to P-format.
Unlike A-block and I-block formats, the B-format does not send a
header. The data is sent immediately, and the end-or-identify message
(EOI) is sent with the last byte.
