Display(D); Translatorsoftware - Keithley 199 Instruction Manual

IEEE-488 PROGRAMMING
3.9.21 Display (D)
The display command controls the ASCII messages that
can be placed onto the Model 199 display. Messages are
controlled with the following commands:
Da = Display character "a", where "a" represents a print-
able ASCII character. Up to 10 characters may be
sent.
D = Restores display back to normal.
Notes:
1. In order to have spaces preceding the beginning of then
message and between message words, use the @ sym-
bol to represent each space. For example, to display the
message "Model 199" starting at the second display
character (one space), send the following command
string:
2. Spaces in a command string are ignored.
3. Sending a message that exceeds 10 characters will result
in the BIG STRING terror message being displayed.
Programming Example-Enter the following statements in-
to the computer to display the message "MODEL 199":
The instrument model number will be displayed. Display
operation may be returned to normal by entering the
following statement:
3.10 TRANSLATOR SOFTWARE
The built in Translator software allows the user ~to define
hi own words in place of Keithley's defined device-
dependent commands. One word can replace a single
command or a string of commands. For example, the word
ACV can be sent in place of Fl, and the word SETUPl can
be sent in place of F3RlTZSOZlUOM2. Also, Keithley com-
mands can be translated to emulate functions of other
units. For example, the word RA, which is used by H-P
to select autorange, can be sent in place of RO. There are
certain words and characters that cannot be used as defin-
ed Translator words. These reserved words and character
make up the Translator software syntax and are listed in
Table 3-13.
