Response Syntax
The following table shows the types of responses for various commands.
The XL100 returns a response (affirmative/negative response) to a command that is
delimited by a single terminator. The controller should follow the one command to one
response format. When the command-response rule is not followed, the operation is not
guaranteed.

Multiple Negative Response Syntax
• If there is an error in any one of the multiple commands that are separated by sub
delimiters, multiple negative responses are returned.
• The response is generated for each erroneous command.
• If there are multiple commands that have errors, the negative responses are
separated by commas.
• The error position number is assigned to the series of commands in order starting with
“1” assigned to the first command.
For a description of error numbers and error messages, see chapter 8, “Error Messages.”
