EKI-1500 Serial Device Servers Excellent Functionality
Advantech's EKI-1000 series have two product categories, one is EKI-1500 Serial Device Servers, and the other is EKI-1300 Wireless Serial Device Servers. Both of them have included new advanced Multi-Access functionality for advanced capability. Furthermore, EKI-1500 Serial Device Servers combine 2 x Ethernet ports which have simultaneous Dual-LAN redundancy functionality for industry-proven reliability. There are some EKI-1000 series Frequently Asked Questions (FAQ) for further understanding.
  Dual Ethernet for Unrivaled Redundant Networking
  EKI-1521/1522/1524/1528/1526 provides Dual Ethernet connections for building reliable and redundant networking. Through the EKI-1521/1522/1524/1528/1526, users can establish 2 physical networks in the same domain, one for the primary connection, and the other is a backup host that can connect to the device servers directly when the primary connection fails. Furthermore, the 2 Ethernet ports can be set to two different networking domains to support different network applications.
 
  * Backup Line Redundancy
  In this case, one PC has two Ethernet cards for the same or different domains to link to EKI-1500 Serial Device Servers. The two Ethernets are both active, where one is for the primary connection, and the other is an alternative backup host that can connect to the device servers directly when the primary fails.
  * Simultaneously Connection Redundancy
  An exclusive new feature for Advantech's Serial Device Servers is support for simultaneous connection redundancy. In this case, both LAN's are connected to multiple hosts (max 5) and If either of the two connections fail, the other LAN will continue the communications between the Serial Devices and the Hosts.
 
  Through Dual Ethernet redundant connections, EKI-1500 Serial Device Servers greatly improve connectivity, reliability, system stability, and simplify redundant configurations, regardless of whether the devices are in the same domain or not.
