Direct IP and Virtual COM Port Connection
In
Virtual COM
Port Mode
the serial ports on the serial server appear to
applications running on the host PC as if the serial ports were physically
located on the host PC. When a virtual COM port is configured on the PC
(using Vlinx Manager), a new COM port appears in the Device Manager.
Windows programs are able to interface to the virtual COM port using standard
Windows API calls. When a program on the PC opens the new COM port, it
communicates directly with the remote serial device connected to the serial
server.
In
Paired Mode
, two serial servers are used to provide a virtual cable
connection between two remote serial devices using the Ethernet network. The
end serial devices communicate data and handshake information directly, as if
they were physically connected in a point-to-point serial connection. Paired
Mode devices are set up as shown in the following diagram and configured
using Vlinx Manager Software or web interface.
