No Error (OK) Responses
Valid commands with no response data and empty lines will be
acknowledged by the “no data OK” response:
OK
TABCRLF
>
Where OK
TAB
identifies the no error response terminated by the
character (>) and
CRLF
added for better readability in terminal
applications.
Data returned by a command begin with OK
TAB
(no error prefix) and is
terminated by the regular response terminator character (>).
For example: a successful
READ VERSION
command returns:
OK
TAB
W1.0.4
CRLF
>
Error Responses
Unknown commands, commands with invalid numbers or types of
arguments, and commands which are unable to immediately perform
their function are acknowledged by the response:
FAIL
TAB
xxx {“text”}
CRLF
>
Where character FAIL identifies the error response and xxx represents
the decimal error code followed by the optional text message string
separated by double-quote characters and terminated by the
CRLF
>.
In case of an error response, status of the instrument should be acquired
by the status command. If the instrument is unable to continue to
operate properly, for example, because of a motor stall or a sensor fault,
you must reset the instrument.
