SW5001 Wireless Serial Server

2.2.1. Virtual COM Mode

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

COM data is converted to Ethernet format. By creating a virtual COM port on a PC, the Virtual COM

driver redirects communications from the virtual COM port to an IP address (and the designated port

number). Figure 2 illustrates a Virtual COM connection diagram.

TCP Server in Virtual COM Mode

SW can be configured in the TCP server mode (with respect to the device as “Client”) with a unique IP

and Port number, and it waits passively for the computer to establish a connection with the serial device

(the client). After the connection is established, data can flow in both directions at the same time.

Configuring SW to TCP server

Using one of the four configuration methods (Telnet, Web, console and LCM controller), one may configure

SW to a TCP Server.

1. IP filter disabled (default)

2. Default SW port number 4660

3. If IP filter is enabled, only the source IP assigned is allowed to be connected to SW.

TCP Client of Virtual COM Mode

SW can be configured to TCP Client mode (with respect to a Host) to establish a TCP connection to an

application server, or the Remote Control Host. Once the connection is complete, multiple hosts of SW

can exchange data with several devices at the same time.
