IS 320 • IGA 320 Manual Data format UPP  27

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

(

arriage

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 () 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

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
