Command Errors and Alarms

If a command received by the device is not recognized or the data is invalid, an error message will be in the

sent in response to any valid RS-232 command.

RS-232 Command Set

A packet without a command is interpreted as a status query. The addressed device responds with a status
only response packet.
Except where noted, a setting command without its parameter queries the command setting. The response
packet data will include the requested data. In general, the query response data will be in the same format
as the parameter for setting the command. For example, the query temperature setpoint command 'SET'
will respond with '<nnn>' as the response '<data>'.
Otherwise, the command is a set command. If the data was set, a status only response packet will be sent.
If the data was not set, the response packet will include an error (<command error>) message indicating
why the data was not set.
All commands are upper case. Spaces are optional. Lower case letters are converted to uppercase when
received.
