Data Message Escape Sequence
In order to remain synchronized with the host in the case of buffer overflows or other communications errors, the
pyrometer uses an escape character for Header byte values that occur in the binary data being sent. The Message
Header Escape character (ESC) is 0x80. Byte values within the message payload which are in the range 0x80-0x85
are preceded by the escape character.
Example : The Ambient Temperature Header, 0x84, occurs in the binary data and is escaped with the ESC character,
0x80:

Data Message Descriptions
Temperature Message
Header Byte: 0x81
Message Format: 0x81 <Temperature 32 bit IEEE>
Description: Target temperature in degrees C.
Example: Target temperature of 674.05 C.
Message: 81 44 28 80 83 00
(Note the insertion of an ESC character, 0x80, due to the presence of the framing character 0x83 in the data.)
Current Message
