Operation
digits (0 to 9) which convey information about the
selection within the category. For example, the
ASCII sequence D2 means “in DISPLAY category,
select VALUE.” The command is like pressing the
[DISPLAY] key to select VALUE.
Floating Point Entries. These entries (also shown in
the table) are ASCII character sequences of arbitrary
length, always terminated with a semicolon (;). The
first character is a letter which designates the category
of the entry. The following ASCII characters - before
the semicolon - define a floating-point number includ-
ing at least one decimal digit (0 to 9) and optional
characters (+ - . e E). Any space character is ignored.
The character e or E is recognized as “exponent” in
E-format notation. For example, any of the following
three entries will set the test frequency to 100 Hz:
F0.l; F1e-1; F100.0E-3;
NOTE: The 2-byte command P2 is recommended as
the first command in a remote programming sequence
because it resets all selections to their power-up (de-
fault) conditions.
3.11.8 Legacy Digibridge IEEE-488
Commands
The legacy IEEE-488.1 Digibridge commands are
supported by the IEEE-488 interface board for com-
patibility with software and drivers written for the
original Digibridge IEEE-488.1 interface boards.
