The “Virtual Serial Ports” functionality for the client can be enabled or disabled by setting or clearing the tick in the Serial
selection box.
A port name can be chosen in the selection box under Com Port of Client and can be added to the port list with Add . It
should be noted that only client serial ports that actually exist can be used. The currently selected entry can be deleted
from the list with Remove .
Apply activates the configuration. The first time this is done for a client, the CP-Link 3 Remote Serial Port Enumerator is
installed first, and then the CP-Link 3 Virtual COM Port driver for each virtual interface. In each case, the installation is
done using the “Found New Hardware Wizard”. The virtual interfaces only appear when the TCP/IP connection to the
client is established.
The current status of the virtual serial interfaces is read and displayed in the list with Refresh . In particular, the list shows
the mapping between COM Ports of the Client (COM Port of Client ) and the virtual COM Ports on the Host ( COM Port on
Host ).
The port names are usually found at the associated device terminal. Serial devices that are connected internally, such as
a serial touchscreen, are documented in the device description (e.g. a label on the rear of a Panel PC).
Note
COM port must be available
A virtual COM port can only be installed when a connection to the client does in fact
exist and the port is available.
