Figure 18. Direct IP and Virtual COM Port Connection
USING VESR9XX SERIAL SERVERS IN VIRTUAL COM PORT MODE
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.
To set up a Virtual COM Port Mode connection:
1. Connect the serial server to the network and a serial device as
described in previous sections.
2. Configure the serial server for VCOM operation (using Vlinx Manager).
3. Configure your software application to communicate via the virtual
COM port.
USING VESR9XX SERIAL SERVERS IN PAIRED MODE
When using serial servers 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 set up as shown in the following diagram and configured
using Vlinx Manager software or web interface.
