9.8 Address (ADR)
For the connecting of several pyrometers with RS485 with one serial interface it is nec-
essary to give each instrument an individual address for communication. First it is nec-
essary to connect each single instrument to give it an address. After that all instruments
can be connected and addressed individually. If parameters may be changed simulta-
neously on all pyrometers, the global address 98 can be used. This allows you to program all pyrometers at
the same time, regardless of the addresses that have already been assigned. If the address of a pyrometer
is unknown, it is possible to communicate with it using the global address 99 (connect only one pyrometer).
9.9
Baud rate (kBaud)
The transmission rate of the serial interface in Baud (Bd) is dependent on the length of
the cable. A standard cable length with RS232 for 19200 Bd is 7 m, with RS485 2 km.
The baud rate is reduced by 50% if the transmission distance is doubled.

Temperature display (°C / °F)
The temperature can be displayed in °C or °F.
9.11
Wait time (only available via interface commands, see section 14, Data format UPP
®
)
Using a pyrometer with RS485 it is possible that the connection is not fast enough to
receive the pyrometer’s answer to an instruction of the master. In this case a wait time
can be set to slow down the data transfer (e.g.: tw = 02 at a baud rate 9600 means a
wait time of
2 /
9600
sec).
10 Settings via interface and software
The operating and analyzing software InfraWin is included in delivery of the pyrometer. With this software all
pyrometer functions also can be used on the PC (except changing the interface or using the test current
function).
This section gives an overview about the functions of the software. Additionally there is a description of the
individual icons in the program’s help menu. Click on the F1 button after InfraWin has been loaded or click
on the ? in the menu bar.
The following descriptions refer to program version 4.0. The latest version is available for free as download
from the homepage www.lumasenseinc.com.
10.1
Connecting the pyrometer to a PC
The program InfraWin can operate up to two devices. For two devices using the RS232 interface, two PC
interfaces must be used. Two devices using RS485 may be operated simultaneously by the same interface,
if two different addresses have been properly entered (see 9.8 Address (ADR)).
10.2
Installation
For installation select the setup program “setup.exe“ from the InfraWin-CD or from the downloaded and un-
packed zip file from the internet and follow the installation instructions.
10.3
Program start
After installation and the first program start a language must be chosen (German, English, French, Italian,
Spanish. The language also can be changed in the program). On the start page the screen shows the follow-
ing icons:
