B.2.3 Command/Response
The command/response portion of the message contains a variable-length character sequence which conveys
command and response data.
If an RC-1160/-1260 receives a message addressed to it which does not match the established protocol or cannot
be implemented, a negative acknowledgment message is sent in response. This message is:
• >add/?ER1_PARITY ERROR'cr''lf']
(error message for parity errors)
• >add/?ER2_INVALID PARAMETER'cr''lf']
(error message for a recognized command which can not 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_CONTROLLER IN LOCAL MODE'cr''lf']
(RC-1160/-1260 in local mode, use the CM command to go to remote mode)
• >add/?ER5_CONTROLLER IN AUTO MODE'cr''lf']
(RC-1160/-1260 in auto mode, use the OM command to go to manual mode)
Note: “add” is used to indicate a valid 1 to 3 character device address in the range between 1 and 255.
B.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
