Data format UPP (Universal Pyrometer
Protocol)
Software commands can be exchanged directly with the pyrometer through an interface using
suitable communication software or by using the “Test” function located in the “Pyrometer
Parameters” window of the InfraWin software package.
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) no handshake;
•
The device responds to the entry of a command with output (such as the measuring value)
+ CR (
C
arriage
R
eturn, ASCII 13), to pure entry commands with “ok” + CR, or “no” + CR.
•
Every command starts with the 2-digit device address AA followed by two lower case
command letters and finished with CR.
Example Read Command:
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%
•
The ASCII parameter “X” indicates a change to be made in a parameter. When used, the
command contains the new value.
Example Write Command:
Entry: “00emXXXX“ +
<
CR
>
The parameter used for the emissivity setting (
ε
) with the address 00 is changed.
Answer: “00em0853“ +
<
CR
>
changes the Emissivity to 0.853 or 85.3%
•
A “?” after the lower case command letters answers with the limits of the respective
settings (only at setting commands, not at query commands).
Example Read Limits Command:
Entry: “00em?“ + ˜CR!
Answer: Could be 00 <CR>, which means that E can vary between 0.050 and
1.000 (or 5% and 100%)
