shop#2017. TERATERM is a free ware; you can find the license requirements
and copyright note in the installation directory.
Connect the sensor module to the USB adapter. If necessary, use the adapter
cable supplied with the adapter.
Now connect the USB adapter to the PC. The installation of the driver should
automatically take place in Windows. If driver files are required, these are
available on the ZIP in the directory „Driver“ for different operating systems.
In rare cases, when the installation of hardware does not work at the first att
-
empt, you can intervene in the control panel. Further hints on this can be found
in the FAQs on the CD. After th hardware is operational, the message „The new
hardware can now be used“ appears on the screen.
Now install the terminal program TERATERM from the enclosed CD and start
the program. Select the interface under „Serial port“ where the device is con-
nected and set the following communication parameters:
Then carry out the following settings under „Terminal settings“:
After this, the system should be operational.
Reading the values
Note: <CR> means “pressing the carriage return key”.
First test the connection with the hardware: For each character sent, the red
LED on the USBAdapter shortly blinks. If the device answers a
telegram, the green LED also blinks. First send the character V <CR>. In res

ponse, the USB adapter should reply back the version string:
As per the revision status of the software the contents can vary, if needed, but
a response must come.
If you can not establish the connection here, then check the hardware in Win-
dows control panel and also all other settings mentioned before.After the con-
nection to the module is functional, first you must initialise the adapter:
T11200 <CR>
To start the reading, the operating voltage to the sensor must be switched on:
IRT78004 <CR>
After this command, the LED near the probe connection glows red and it shows
that the operating voltage is present at the measuring probe.The sensor replies
with 8 characters, in the example it is :3F3944C1. These are the first set of
measured values.
