R1.1, July 2021
5.2 Command Line Interface (CLI)
The EMCH is providing a low level command line interface (CLI) which allows to set certain
operational parameters and to display run time information from the MCH and the system.
5.2.1 COM-Settings
The CLI can be accessed over the front MicroUSB port. To establish a connection to a host PC,
use a serial terminal program e.g. Terra-Term, HTerm, Putty, e.g.
Configure the COM port settings as followed:
Table 3: COM port settings
If the terminal is opened, press enter to see if the connection is established successfully.
You can now type “help” to see the list of available commands. Press enter to call the
previous command again.
NOTE: Depending on your operating system, you need to download and install the FTDI-chip
driver manually. Drivers can be downloaded at http://www.ftdichip.com/FTDrivers.htm.
Installing the driver automatically by the windows update may take up to a few minutes.
