Data format UPP

(Universal Pyrometer Protocol)
Via interface and a suitable communication software or via “Test” function of the InfraWin software (see 10.7
Basic settings
Æ
Test) commands can be exchanged directly with the pyrometer.
Note:
The ONL/OFFL switch must be in the ONL position before adjusting the
following parameters via the software (see 8.2).
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 Re-
turn, 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 emissivity), followed, if necessary for that com-
mand, by the ASCII parameter “X” and finished with CR. If this parameter “X” is omitted, then the device
answers with the current set 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 (
ε
) of the device with the address 00 is returned
Answer: “0970“ +
<
CR
>
means Emissivity = 97.0%
