-1-
This optional communications is for reading measured data, parameters, and storage data of IR-AH
series handheld radiation thermometers by a personal computer.
By this communications, parameters cannot be programmed to your thermometer by a personal
computer.
Start-stop synchronizing system RS-232C
Half-duplex communications system
Transmission speed 9600bps
Start bit 1 bit
Data length 7 bits
Parity bit Even
Stop bit 1 bit
Character code ASCII
BCC (Block check code) None
Data transmission procedure None
1. General
2. Communications specifications
During measurement, any answer to the data being received is not executed due to
the speed of the CPU.
Caution
This communications is onlyfor "Reading" and "Answer".

3. Communications procedures
R:
Reading
A: Answer
Reference
"ETX" is added when the data is one, or added to the last data when plural data are
answered to 1 command.
"ETB" is added to data before the last data when plural data are answered to
1 command.
Reference
A sub-command in the "Reading" command returns as the sub-command in the
answer.
This format is applied to the data positively transmitted from your thermometer, too.
Reference
Error data No.: First data position (the position counted from the position next to
"STX") where an error was detected
Make sure not to use "BCC code" due to the specifications of CPU and capacities of
ROM/RAM.

3.2 Data expression
Data is expressed by the format with fixed length of character between " =", "," and "ETX (ETB)".
3.3 Numeric data
Data is characters with fixed length and right justified. (except Para. [4.3.1 Reading model number] with
left justified)
Numeric figures exist before and after a decimal point.
The following list is for treatment of positive sign, negative sign, and “0” at receiving and transmitting.
Item Condition Contents
Sign At receiving Positive sign: “ + ” or “space ( )” is acceptable. Negative sign: “ – ”.
“ + ” or “ – ” is placed just left to a numeric figure.
At transmitting Positive sign “ + ” is expressed by “space ( )”
Negative sign “ – ” is placed just left to a numeric figure.
“0” at
higher digits At receiving “0” (zero): “0” or “space ( ) ” is acceptable.
At transmitting “0” (zero): Zero-suppressed
Data length
At receiving Variable length
When no data exists, a positive answer returns assuming that no setting
is changed.
At transmitting Fixed length Refer to [4. Communications format].
ASCII commands ASCII codes
STX 02h
ETX 03h
ETB 17h

CR 0Dh
3. Communication procedures
The following data are not acceptable as numeric figures.
"12 3", "- 234", "-.123", "123 ", "123. " etc.

4. Details of format
Add control codes when following commands are used for communications items
(Refer to [3.1 Basic communications format].)
For numeric data, refer to [3.3 Numeric data].
Reference
PV command is not for reading. Data is transmitted from your thermometer positively.
Caution
In the standard measurement of your thermometer
, PV command is
transmitted
at the
releasing Meas key.
In the continuous measurement, PV command is transmitted at every display renewals.
Reference
If the integral includes a sign, it becomes
2digits.
Reference
Aspace is inserted in the most significant
digit.
When the data status is "1" or "2",
