7.1.3.2 Command and Query Format
Commands must be sent in ASCII format and terminated with either a carriage return
(<cr>), linefeed (<lf>), or both. Commands are not case sensitive. Each query returns a
response. If an error is detected the response will include an error flag.
Command or Query field:
Unless otherwise specified, commands are typically con-
verted to queries by appending a question mark to the command. Table 7.1.3.5 lists all
of the CPG 2500 command or query keywords.
Data field:
The data field is either in ASCII {string} or numeric {value} form. In the case
of multiple data fields, commas are required to separate the fields. Queries do not have
a data field. String (text) or value (numeric) data are acceptable in any of the following
formats:
Examples of {string} data:
ON, OFF, mBar, inHg
Examples of {value} data:
1, 1.0, -5.678, 25.68324e-5
7.1.3.3 Command Set Definitions
In this manual a data entry made up of alpha characters is defined as a string, as op-
posed to data containing only numbers, such as “Enter 1 for ON or 0 for OFF” where 1
and 0 are defined as values.
Command:
Any command or query listed in Table 7.1.3.5. For commands that take
boolean data the following strings are acceptable:
0
1
False True
No
Yes
Off On
Separator:
Space (SP).
Data:
ASCII representations of numbers, {value}, or alpha characters, {string}, data as
defined above. When sending code a literal variable replaces the brackets and the en-
closed character(s) shown in the following examples.
Termination:
Linefeed (LF) or carriage return (CR) is used to signal the end of a com-
mand statement. For IEEE-488.2 operation “EOI” is an acceptable alternative.
Always send commands in one of the following formats:
1. [Command] [Termination];
2. [Command] [Separator] [Data] [Termination];
