Overview
Almost all communication devices including PC are using serial transmission. In this type,
devices send and receive data in the order of each byte. The serial communication is quite
simple to implement but has weaknesses like short distance and hard maintenance.
EZL-200F lets the serial devices connect to the Internet. To communicate on the Internet,
devices should use TCP/IP protocol, so EZL-200F processes the converting serial data to
TCP/IP.
EZL-200F supports RS-422 and RS-485 as well as RS-232 including the Telnet COM Port
control option (RFC2217), SLIP (Serial Line Internet Protocol) and etc. Furthermore, MIC real
time operating system developed by Sollae Systems is loaded.
