Overview
With the development of Internet technologies, demands for data communication
through the Internet keep increasing. However, to have data communication through
the Internet, users must use TCP/IP protocol which is the basic communication protocol
of the Internet. In other words, to connect a device to the Internet, the user must
implement TCP/IP protocol. To implement TCP/IP protocol, the user must implement
TCP/IP protocol by themselves, port open TCP/IP, or use an OS. However, these
methods are quite burdensome in terms of time, cost, and technology.
As a family of serial to TCP/IP protocol converters, ezTCP series manufactured by
Sollae Systems provide TCP/IP communication functions (Internet communication
functions) "only through serial port connection." The ezTCP series perform TCP/IP
protocol processing on data received from the serial port, and send the processed data to
the Internet. Similarly, the ezTCP series perform TCP/IP protocol processing on data
received from the Internet and sends the processed data to the serial port.
EZL-300W Lite(it is pronounced as “lait”), which is one of ezTCP products, provides
TCP/IP communication through IEEE802.11b (wireless LAN). In other words, like
other ezTCP products, EZL-300W Lite TCP/IP-processes data received from the serial
port and sends the processed data to the wireless LAN network. And EZL-300W
Lite(hereafter ezTCP) TCP/IP-processes data received from the wireless LAN network
and sends the processed data to the serial port.
ezTCP supports the infrastructure network through the Access Point (AP) and also
provides an "ad-hoc" network function supporting peer to peer communication without
any AP.
As ezTCP provides DHCP as well as TCP/IP/UDP, ezTCP can be applied to cable
networks.
