Figure 12. 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.
