TC3x Multiplexer User's Guide

6.1.4 Chopper.exe

Due to the limited memory of the module's hardware the multiplexer implementation can handle only
smaller data packages (the frames for the different ports). For this reason the chopper.exe chops large
incoming frames into blocks of maximum 100 bytes. This maximal frame size can be configured in the
simulation.ini file (refer to chapter 6.2.1 )

6.1.5 Muxtester.exe

The muxtester.exe is an application only for debug and test reasons. It simply analyzes received
frames, traces them for frame errors and writes error information to an error file. Currently it is
connected to the muxappl.exe to examine the frames sent to the module and to the modules port.exe
to analyze the frames sent out of the module into the PC multiplexer system.

6.2 Additional Modules and Files

6.2.1 Simulation.exe and Simulation.ini

Simulation.exe provides the user interface for the PC multiplexer adaptation. The PC multiplexer with
all modules belonging to the system can be started clicking the Start button. All settings, such as port
configuration and pipe names etc. are stored in the simulation.ini file. Of course the complete multi-
plexer configuration can also be stopped. All modules are closed, ports are freed etc. In addition to the
start-up, initialization or stopping procedures of the whole multiplexer system, the application simula-
tion.exe provides the functionality to switch the multiplexer on or off. A Trace window can be opened
and closed by pressing the appropriate buttons.

6.2.2 Log.exe

This is a console application which allows to decode and display the internal messages. The messages
decoded and displayed have to be explicitly sent to an instance of log.exe for display. Log.exe is a
development and debug tool which isn't used in the running multiplexer system. It simply provides the
functionality to connect log.exe e.g. instead of or in addition to an instance of port.exe to the
controller.exe to have all incoming messages displayed.

6.2.3 Send.exe

This is a command line tool which serves to send any internal messages to any possible pipe. It is not
used directly inside the running PC multiplexer system. Nevertheless it is very useful for development.
It is used to send the message "disable multiplexer".

6.2.4 Process.exe

This is also a command line tool created for development reasons and has nothing to do with the
multiplexer functionality. It is nothing but a simple task manager used to list all running processes and
provides the functionality to kill all running processes with the same name by one command (e.g. kill all
running instances of port.exe with one call). After pressing the Stop button within the application
simulation.exe all multiplexer related applications will be stopped by sending a "termination" message.
Sometimes the processes do not stop; then it is necessary to kill them via process.exe.
