2. Communication LMS to PC with MST

MST Provides a simple data connection. The Hardware connection between PC and LMS is
shown in section B3.

Please select 

Options

 in the start window and set your connection parameters.

Note:       

Always select 9600Bd . MST will automatically use the highest Baud rate possible

when started.

The Software is now ready.

Within the 

Start

 button you will have several applications which can be started.

For every application MST_Demo will create a configuration file in the MST home directory. This
configuration file is a text file and can be edited with every editor.

In this quick start manual the application 

Record LMS scan data

 and 

Play back LMS scan data

are discussed. The other applications follow the same idea by principle.
