4 Installation of the components for the PC Mux
4.1 Hardware Installation
The following chapters describe the two different possibilities how to realize the physical connection
from the application (PC) to the module.
4.1.1 Using virtual COM Ports
Creating virtual COM ports avoids the installation of 7 COM ports (8 Port serial card) in your PC. The
applications (e.g. terminal programs) must be connected to the 3 virtual COM Ports. The multiplexer
internally connects these 3 Ports to 3 other virtual Ports and maps them onto the one serial Port which
is physically connected to the DSB35 or TC35T. See chapter 4.2.1 to install the virtual ports.
Figure 2: Example configuration of the COM Ports when using virtual COM Ports
Note
:
When using virtual COM Ports RTS/CTS are not passed to the application. So data transfer is not
possible.
