Terminal Mode Commands MN/KST2000L.IOM
7.2.3 Command/Response
The command/response portion of the message contains a variable length character
sequence, which conveys command and response data. If a KST-2000L receives a
message addressed to it, which does not match the established protocol or can not be
implemented, a negative acknowledgement message is sent in response. This message is:
>add/?ER2_INVALID PARAMETER'cr''lf']
(error message for a recognized command which cannot be
implemented or has parameters which are out of range)
>add/?ER3_UNRECOGNIZABLE COMMAND'cr''lf']
(error message for unrecognizable command or bad command
syntax)
>add/?ER4_CONVERTER IN LOCK MODE'cr''lf']
(controller in LOCK mode, must go to ENABLE mode first or user
is directing redundancy commands to the offline unit)
>add/?ER5_NOT SUPPORTED BY
HARDWARE'cr''lf']
(the command is a legal command but it is not supported by the
current hardware configuration)
>add/?ER9_HARDWARE NOT OPERABLE'cr''lf']
(This error is issued when hardware prevented the system from
carrying out the users remote command request.)
7.2.4 End Character
Each message is ended with a single character which signals the end of the message:
• “cr” Carriage return character for commands
• “]” End bracket for responses
