Figure 3.4 Direct IP and Virtual COM Port Connection
In
Virtual COM
Port Mode
a PC can communicate across the network to the serial server as if the serial
ports on the serial server are the PC’s serial ports. When a virtual COM port is configured on the PC
(using Vlinx Manager) a new COM port appears in the Device Manager. Windows programs using
standard Windows API calls are able to interface to virtual COM ports. 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 (connected to serial devices via their serial ports) are connected to the
network. The serial devices communicate directly, transferring data between devices as a point-to-point
serial connection. Paired Mode is set up as shown in the following diagram and configured using Vlinx
Manager software or web interface.
