11 Data format UPP  (Universal Pyrometer Protocol)
Via interface and suitable communication software or via “Test” function of the InfraWin software (see 7.7
Basic settings  Test) commands can be exchanged directly with the pyrometer.
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 level of emissivity

), finished with CR
This is followed, if necessary for that command, by the ASCII parameter "X". If this 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 97.0%
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

: AAezX 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
Clear times of the
maximum value
storage: AAlzX 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: AAasX X = 0 or 1 0 = 0 - 20 mA; 1 = 4 - 20 mA
Reading basic
temperature range: AAmb Output: XXXXYYYY (hex 8-digit, °C or °F)
XXXX = beginning of temp. range
YYYY = end of temp. range
Reading temperature
sub range: AAme Output: XXXXYYYY (hex 8-digit, °C or °F)
XXXX = beginning of temp. range (°C or °F)

Setting of temperature
sub range: AAm1XXXXYYYY XXXX (hex 4-digit) beginning of temp. range (°C or °F)
YYYY (hex 4-digit) end of temp. range (°C or °F)
Address: AAgaXX XX = (00 ... 97)
00 ... 97 = regular device addresses
99 = Global address with response
98 = Global address without response
(only setting commands!)
