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.
CSE-H21 in ezTCP product group is a product that provides TCP/IP communication
through Ethernet. In other words, like other ezTCP products, CSE-H21 sends data from the
serial port to the LAN after TCP/IP processing and vice versa.
As CSE-H21 has 2 RS232 ports, it can be connected to two RS232 devices in the same
time. And it is easy CSE-H21 to attach to user systems because of its compact size.
Because it has SSL and SSH function, user can communicate more safely. And it provides
DHCP and PPPoE functions, so that it can be applied to the cable network and the xDSL
network. And it has DDNS(Dynamic DNS) function, so it can be used more easily in the
internet.
It can be operated wide range temperature condition and its serial ports are isolated
electrically and there is surge protection function on the Ethernet port, so it is very suitable
for noisy industrial environment.
It also provides debugging function, so user can solve the problem with ours.
