7 Data format UPP (Universal Pyrometer
Protocol)
Via interface and suitable communication software or via “Test” function of the InfraWin
software (section “pyrometer parameters”) commands can be exchanged directly with the
pyrometer.
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 with the entry of a command with: output (e.g. the measuring value) + CR
(Carriage Return, ASCII 13), with pure entry commands with "ok" + CR. With invalid commands
the instruments answers with „no“ + 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.
Example: Entry: “00em“ + CR
The emissivity setting of the device with the address 00 is returned
Answer: “0970“ + CR means emissivity = 0.970 or 97.0%
