7 Data format UPP (Universal Pyrometer
Protocol)
The data exchange occurs in ASCII format with the following transmission parameters:
The data format is: 8 data bits, 1 stop bit, even parity (8,1,e).
The device responds to the entry of a command with: output (e.g. the measuring value) + CR
(Carriage Re-turn, ASCII 13), to pure entry commands with "ok" + CR.
Every command starts with the 2-digit device address AA (e.g. "00"). This is followed by 2 small
command letters (e.g. "em" for level of emissivity ), finished with CR.
This is followed, if necessary for that command, by the ASCII parameter "X". If this parameter
"X" is omitted, then the device resets with the current parameter.
A “?“ after the small command letters answers with the respective settings (only at setting
commands, not at enquiry commands).
Example: Entry: “00em“ + <CR>
The emissivity setting (ε) of the device with the address 00 is returned
Answer: “0970“ + <CR> means Emissivity = 0.97 or 97.0%
