Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic o ...
's first Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1 ...
international standard for real-time data transmission.
*An Ethernet-based industrial networking protocol developed in-house by LSIS guarantees real-time transmission and is registered as an international standard. (IEC 61158-3-21: 2010, IEC 61158-4-21: 2010, IEC 61158-5-21: 2010, IEC 61158-6-21: 2010, IEC 61784-2: 2010, IEC 62439-7)
*An embedded Ethernet switch with two ports enables the network expansion in a daisy chain without the need for an additional external switch, easy installation and wiring reduction.
*With 100Mbit/s/1Gbit/s transmission speed, electrical and optical media can be used together.
*Supports transmission modes such as Unicast
Unicast is data transmission from a single sender (red) to a single receiver (green). Other devices on the network (yellow) do not participate in the communication.
In computer networking, unicast is a one-to-one transmission from one point in ...
, Multicast
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with ...
and Broadcast.
*Supports "Store & Forward”and “Cut Through” switching.
