8 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
(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 "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 ( ) of the device with the address 00 is returned
Answer: “0970“ + CR means Emissivity = 0.97 or 97%
Description
Command Parameters
Reading temperature
value:
AAms
Output: XXXXX (dec., in 1/10 °C or °F)
(77770 = Instrument’s temperature too high
88880 = temperature overflow)
Reading temperature
value repeated:
AAmsXXX
XXX = 000...999 (XXX = number of measuring values)
Emissivity:
AAemXXXX
XXXX = (0100 ... 1000‰) (decimal)
Transmittance:
AAetXXXX
XXXX = (0100 ... 1000‰) (decimal)
Ambient temperature
compensation:
AAutXXXX
XXXX = value of ambient temperature, 4-digit, hex XXXX
e.g. FFEC corresponds to -20 degrees - 99
dez
= FF9D
hex
means: automatic, no manual compensation
