-1-
This optional communications is for monitoring measuring condition by communications and for
setting and reading parameters of IR-FA series fiber optic thermometers (Model: IR-FAIS,
IR-FASS, IR-FAQHS, IR-FACRS) through a personal computer.
In this communications, the transmission speed is variable but other parameters are fixed.
Also, for the connection with multiple thermometers, it is necessary to set an address to each
thermometer. For the setting of the address, refer to the separate instruction manual IR-FA series Fiber
type radiation thermometer (INST.No.INE-378-P) and IR-FACR series Fiber type radiation
thermometer (INST.No.INE-414-P).

Warning
(1)
Insert a driver to the concave part at
the upper side of the terminal board.
(2)
Lift the driver shank up and push up the
metal hook with the tip of the driver.
(3)
Insert a lead wire to the opening of the
lower side of the terminal board.
(4)
The lead wire is fixed by removing the
driver.
Caution
When connecting the optical connector of the fiber
optic assembly to the optical connector of the
thermometer, make sure to turn it with your hand.
(Never turn it by using a tool like as pliers.)

4.3 Data expression
Numeric data
Data is characters with fixed length and right justified.
Sign
At receiving: “ + ” or “space ( )” is acceptable
At transmitting: “ – ” is placed just left to a numeric figure. “ + ” is expressed by “space ( )”
“0” at higher digits
At receiving: “0” (zero) or “space ( ) ” is acceptable.
At transmitting: “0” (zero) is suppressed except specified parameters.
