If you want to use a longer serial cable you have to reduce the baud rate of
the LPR-B station. Ask the Symeo Service for detailed information.

8.4 Connection inside the LPR-B station
To analyze the serial connection between your PC and the LPR-B station it is the best to
connect the serial cable inside the LPR-B station. Open the LPR-B station. Make sure that
you do not pollute anything inside the LPR-B station.
There are 4 serial ports for connection. One port is for the configuration of the LPR-B station
(S4: parameterization port) another one is the port for the distance data (S2: binary data).
Two other serial ports (S1 and S3) are not used for commissioning the system.

For analyzing the LPR-B station use first the parameterization port (S4). Connect the serial
cable with the parameterization port (S4) and the COM interface with your computer.
If you use a USB-RS232 converter make sure that all necessary drivers are
installed for this hardware.
