11.7.2 Data exchange via serial interface
For this you just need a 1:1 cable (or a null modem cable if you are using ComB) and an
installed terminal program. On each Windows PC you should have the program ‘Hyperterm’
already installed.
1. Start Hyperterm and enter any name for the new connection.
2. Choose the COM port which is connected to your PC.
3. Set up this port with following parameters:
Baud rate
115200
Databits
8
Parity
None
Stopbits
1
Protocol
None
4. Hyperterm is now ready to receive data. To test the connection press Print/Log at LMG,
choose ‘ComA: 115200’ as destination. If the baud rate should not be 115200 please set it
via Set. If you are using ComB do the same for it..
The mode should be set to 'one-time' and ‘output as table’.
5. Press Enter to start the transfer.
6. Hyperterm should now display the values. If not, check the correct ports, cable and all
settings. Check also that Hyperterm is ‘on-line’. If not, open the connection.
7. Hyperterm receives correct data. You can save the following data into a file via menu
‘transfer’ and ‘save text’
8. Press at LMG Print/Log again and choose now 'every cycle'. Start logging with Enter.
In Hyperterm you see now the received data which are stored in background.
9. To stop the logging press Print/Log and Enter.
10. Stop the recording of Hyperterm by closing the text file. If you open this file with any text
editor you see the logged data.
11.7.3 Country dependent numbers
Float numbers are output with a dot '.' as decimal separator. This can cause problems, when
your computer is set up to use ‘,’ as separator (like for example in Germany). In this case set
up your operating system to use the dot ‘.’ as separator.
11.7.4 Reading data into EXCEL
First make sure, that the decimal separator is set up correctly. Then start Excel and load the
file. Choose the number of lines Excel should skip to reject the header.
As column separator select a space.
Now the data from the file are read into Excel without any problems.
