8.4 Baud rate
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.
8.5
Wait time (tw)
Using a pyrometer with RS485 it is possible that the connection is not fast enough to
receive the pyrometer’s answer to a command of the master. In this case a minimum
delay time (tw) can be set. The pyrometer waits this time until it answers a master in-
quiry (e.g.: tw = 02 at a baud rate 9600 means a wait time of
2 /
9600
sec).
9 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.
Note: Before adjusting the parameters “emissivity”, “exposure time” and “analog output” via
the software, the online Ù offline switch (DIP-switch Nr. 4) must be set to the “online”
position in the pyrometer!
9.1
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 8.3 Address).
9.2
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.
9.3
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:
