7 Data format UPP (Universal Pyrometer
Protocol)
Via interface and suitable communication software or via Test function of the InfraWin
software (see
Basic settings
Test) 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 ), 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
( ) of the device with the address 00 is returned.
Answer:
“0970“
+ CR means Emissivity = 0.97 or 97.0%

XXXX = value of ambient temperature, 4-digit, hex
XXXX e.g. FFEC corresponds to -20 degrees
- 99
