Reading out Measuring Data
You can transfer the measuring data to a PC. To do this, connect the PC to the RS232 interface of TTI-22
and use a terminal program or connect the PC to the Ethernet interface of TTI-22 and use a web browser.
8.1
Transferring Measuring Data via RS232
For transferring the data, connect the RS232 interface on the rear side of TTI-22 with the RS232 interface of
the PC.
1.
Connect the interfaces of TTI-22 and the PC with a data cable (e.g. a three-wire shielded cable with
the lines TXD, RXD and GND).

Interface connection
Caution:
The instruments earlier TTI-22 features another interface connection with the wires 2 (RXD) and 3
(TXD) crossed. Therefore you cannot use the interface cable of these instruments for TTI-22 unless you
use an adapter which crosses RXD and TXD. We recommend using the appropriate cable with the above
specified interface connection (see Fig. 8 - 1).
2.
Make sure that the interface parameters of TTI-22 and the PC match each other.
3.
Configure the TTI-22 interface in the menu 2 Edit Configuration > 4 RS232 Config. as follows:

4.
Select the same interface settings in the terminal program on your PC as you set for RS232.
5.
To request data, use your terminal program to send the according command to TTI-22 (see Table
8.1).
Each command consists of two words followed by a <CR> character (carriage return, 13hex), e.g.
"GET DATA <CR>". Make sure that you set your terminal program accordingly.
The response of TTI-22 consists of several lines separated by <CR> (carriage return) and <LF>
(line feed) (see Table 8.1).
