Connection layout of plug module
Quick start with ‚TERATERM‘
TERATERM is an universal, efcient terminal program which you can
nd in the installationversion on the enclosed CD. TERATERM is a free
ware; you can nd 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 soft
-
ware should automatically take place in Windows XP. If driver les are
required, these are available on the CD in the directory „Driver“ for dif
-
ferent operating systems.
In rare cases, when the installation of hardware does not work at the
rst attempt, 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 connected 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 response, the USB adapter should reply back the version string:
As per the revision status of the software the contents can vary, if nee
-
ded, but a response must come.
If you can not establish the connection here, then check the hardware
in Windows control panel and also all other settings mentioned before.
After the connection to the module is functional, rst you must initialise
the adapter:
T11200 <CR>
To start the reading, the operating voltage to the sensor must be swit
-
ched 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 rst set of measured values.
