The GF-EM-100 is an easy-to-use Ethernet-to-Serial Converter that allows you to connect any existing RS232-based Device to the 10BaseT Ethernet LAN. There are several ways in which you can communicate with the GF-EM-100:

COM port redirection - If you want to continue using existing PC/Windows software (that was meant to communicate with your Serial Device directly, via the RS232), then our Virtual Serial Port Driver (VSPD) is the solution for you. VSPD creates a number of Virtual Serial Ports on your PC. Each port works exactly like a normal hardware port but in reality reroutes the data via the TCP/IP network. With the VSPD installed you can continue using your PC software as if your Serial Device was still attached to the PC’s Serial port.

Direct Socket Communications - If you are creating your own PC software, then you can communicate with the GF-EM-100 directly. Modern software design packages like Visual Basic from Microsoft make it extremely easy to send and receive UDP packets. Our Application Note Using VB to communicate with the GF-EM-100 provides a detailed information on this subject.

Virtual Serial Link - If you are using a non-PC device to communicate with the GF-EM-100 or your PC is not running Windows, then you can use two GF-EM-100s to form a virtual serial link over the TCP/IP network. This way you will still have a simple RS232 interface on both sides of the link.
