9 Data format UPP (Universal Pyrometer
Protocol)
Via interface and a suitable communication software or via “Test” function of the InfraWin
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 to the entry of a command with: output (e.g. the measuring value) + CR
(Carriage Return, 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
e
), 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 (
e
) of the device with the address 00 is returned
Answer: “0970“ + CR means Emissivity = 0.97 or 97.0%
