Result codes and messages
Each input record generates a result code which is sent to the user. Only one
code is sent regardless of the number of commands in the record. The reply
is in one of two formats:
• Numeric replies contain a one- or two-number code
• Verbose replies contain one or more words
Table 159 shows the codes for each reply in both formats, and explanations
for the codes.
Note 1: Verbose commands are the default and appear in upper case
characters only. Numeric commands are sent by issuing the Numeric
Results code command (explained later in this document).
Note 2: All verbose codes and messages are preceded and terminated by
the user defined Terminator and New Line characters. The default, or
reset, characters are the ASCII Carriage Return, and ASCII Line Feed.
The Numeric codes are preceded and terminated by the Terminator
character only.
Note 3: The Suppress result command (explained later in this document)
will disable the sending of these codes. If in RS-232-C DAC Host modes,
this command is ignored.
