4.2.1. Virtual COM Mode

The Virtual COM software emulates a serial port with Internet or LAN topology. In the Virtual COM

Mode, COM port data (RS232) is encapsulated to Ethernet data format. By creating a virtual COM

port on a PC, the Virtual COM driver redirects communications from the virtual COM port to the

destination IP address (and the designated port number) by encapsulated COM data into IP data.

Fig 5. illustrates a Virtual COM connection diagram.

SW5002 can be configured in the TCP server mode (PC as a client) with a unique IP and Port number,

and SW5002 waits passively for the PC to establish a connection to. After the connection is

established, PC can communicate to serial devices through SW5002.

Configure SW5002 to be TCP server

Using one of the three configuration methods (Telnet, Web, and console), User can configure SW5002

to be as TCP Server as following.

 Disabled the IP filter (default)

 Set the port number (default port is 4660 for COM1, 4661 for COM2).
