1. Overview
1.1. Overview
Along with the development of the Internet, the demand for data communication
functions has increased recently. Data communication over the Internet requires using
TCP/IP, the Internet communication protocol. That is to say, in order to connect a
system to the Internet, TCP/IP protocol must be implemented. It is possible to
implement TCP/IP by directly implementing the protocol, porting public TCP/IP, or
using Operating System (OS). However, all these methods impose burdens on the
developer in time, cost, and technology.
ezTCP series, a Serial ↔ TCP/IP protocol converter product group of Sollae Systems,
enables you to use TCP/IP communication (the Internet communication) function simply
by “connecting the cable to a serial port”. ezTCP sends data from the serial port to the
Internet network after TCP/IP processing, and vice versa.
EZL-410 in ezTCP product group is a product that provides TCP/IP communication
through wired or wireless LAN. In other words, like other ezTCP products, EZL-410
sends data from the serial port to the wired or wireless LAN after TCP/IP processing and
vice versa.
EZL-410 has 4 serial ports therefore it provides TCP/IP function to 4 serial devices.
It provides not only DHCP but also PPPoE, so that it can be applied to the cable network
and the xDSL network.
As EZL-410 provides SSL security function, it can be used in a system that requires a
high level of security.
It is a modular type and 3.3V power is required.
