This section describes the output format of the BINARY data that is disclosed. For the
BINARY output format, see "BINARY Output" on page 5-2. For other BINARY data
types, see "Identifier" on page 5-3.
The measured data is output using signed 16-bit integer; the computed data is output
using signed 32-bit integer. These integers can be understood as physical values by
adding the decimal point and the unit.

• The FD (FD1) command is used to output the most recent measured/computed data.
• The FF (FEGET, FERESEND, and FEGETNEW) command is used to output the
FIFO data. The decimal point position and unit can be determined using the FE
command.
• The ID number of the output format is 1. See "Identifier" on page 5-3.
