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.
Configure the serial server with the appropriate network settings (using
Vlinx Manager or the web interface).
Configure your software application with the appropriate IP address and
port number to communicate with the serial device(s).
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
