NET232-DCE (female)
Intelligent Ethernet to Serial Cable Adapter $99

The NET232 is an intelligent plug-and-play RS232-to-Ethernet cable adaptor that enables any device or machine with a serial port, to become Ethernet network and Internet enabled.   Go from Ethernet to serial with the NET232.  It features a powerful built-in device server, so you can access your serial device from anywhere in the world over internet!  The NET232 is easily configured via a web page, and can also be set up through the serial port. You can use DHCP, AutoIP or assign a Static IP address to the NET232!

There are two basic modes of operation, "Redirector" and "Serial Tunneling".

Redirector Mode:  In Redirector Mode, only one NET232 is needed per serial device.  ComPort Redirector Software (free with purchase) is installed on your Windows PC to create a "virtual" COM Port (e.g. COM3).  You can then use this COM port in your Software application just as you would any physical COM port attached to your PC.  Create a virtual COM Port for every NET232 device on your network and connect to them all from a single PC!

Serial Tunneling Mode:  In Serial Tunneling mode, two NET232's are used to create a "Serial Tunnel" over Ethernet. This can be thought of as cable replacement. Each NET232 is configured to have a remote IP address that is the other NET232 in the pair.  No software is required to be loaded on a PC.  This is also an excellent option for non-windows PCs or computers.  Now you have an infinite length RS232 cable that is connected over the internet.
