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

Exposure time t

X = 0 ... 6 (decimal)

0 = intrinsic time constant of the device
1 = 0,01 s

3 = 0,25 s

5 = 3,00 s

2 = 0,05 s

4 = 1,00 s

6 = 10,00 s

X = 0 ... 9 (decimal)

0 = Maximum value storage off
1 = 0.01 s 4 = 1.00 s

7 = external deletion

2 = 0.05 s 5 =

5.00 s

8 = automatically deletion

3 = 0.25 s 6 = 25.00 s

External clearing:

AAlx

Clearing the max. value storage
(only with lz = 7, external)

Analog output:

X = 0 or 1

0 = 0 - 20 mA; 1 = 4 - 20 mA
