:BORDer? Query byte order
Short-form format: :form:bord?
Response message:NORM or SWAP
This command is used to control the byte order for the IEEE754 binary formats. For normal byte order,
the data format for each element is sent as follows:
Byte 1 Byte 2 Byte 3
Byte 1 Byte 2 •••
For reverse byte order, the data format for each element is sent as follows:
Byte 4 Byte 3 Byte 2
Byte 8 Byte 7 •••
The "#,0" Header is not affected by this command. The Header is always sent at the beginning of the data
string for each measurement conversion.
The ASCII data format can only be sent in the normal byte order. The SWAPped selection is simply ig-
nored when the ASCII format is selected.

40 END
Line 10 Two commands in this program message; the first reverses the binary byte order, and the sec-
ond queries the byte order.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the byte order (SWAP).
