9 Data format UPP (Universal Pyrometer
Protocol)
You can communicate directly with the pyrometer through the interface and a suitable
communication software or via the “Test” function of the InfraWin software.
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
(
C
arriage
R
eturn, 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 "X” parameter. If the
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 (
δ
) of the device with the address 00 is returned
Answer: “0970“ +
;
CR
=
means Emissivity = 0.97 or 97%
