Setup and Connections
Using VESR9xx Serial Servers in Direct IP Mode
A
Direct IP
connection allows applications using TCP/IP or UDP/IP socket
programs to communicate with the COM ports on the serial server. In this
type of application the serial server is configured as a TCP or UDP server.
The socket program running on the PC establishes a communication
connection with the serial server. The data is sent directly to and from the
serial port on the server.
To set up a Direct IP Mode connection:
1.
Connect the serial server to the network and a serial device as described
in previous sections.
2.
Configure the serial server with the appropriate network settings (using
Vlinx Manager or the web interface).
3.
Configure your software application with the appropriate IP address and
port number to communicate with the serial device(s).
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.
