Exception response codes:

01 - Illegal function

02 - Illegal data address

03 - Illegal data value

06 - Busy, rejected message. The message was received without errors, but the instrument is being

programmed from the keypad (only for requests accessing setup registers).

NOTE When the character framing, parity, or redundancy check detects a communication error,

processing of the master's request stops. The instrument will not act on or respond to the message.
