4.2 Data Format
4.2.1 Program Data Elements
The controlling PC uses Program Data Elements to send information to the device.
Program Data Elements are defined by IEEE488.2-1992. The device accepts the
following elements:
<CHARACTER PROGRAM DATA>
A <CHARACTER PROGRAM DATA> element is used to convey parameter information
best expressed mnemonically as a short alpha or alphanumeric string. Characters

to the device. Characters used within this element are not case sensitive.
Examples: 5 , -23.5 , 123E-3 , +0.123
<NONDECIMAL NUMERIC PROGRAM DATA>
A <NONDECIMAL NUMERIC PROGRAM DATA> element is used to send numeric
integer values to the device. Characters used within this element are not case
sensitive.
Examples: #H1E , #036 , #B11110 (hexadecimal, octal, binary representation of 30)
<STRING PROGRAM DATA>
A <STRING PROGRAM DATA> element allows any character in the ASCII code to be
transmitted as a message.
Examples: Hello , ”Good luck” , ’How are you?’
