EKI-1521/1522/1524 User Manual 2
1.1 Introduction
Advantech's EKI-1521, EKI-1522, and EKI-1524 series of Industrial Device Servers
(the following manual will use EKI-152X series instead of complete model name) are
a robust, feature-rich, and cost effective way to network-enable equipment in an
industrial automation environment. The EKI-152X series provides one, two, or four
serial ports, two independent Ethernet ports, a wide range of power inputs, and a
compact slim design, making them an ideal solution for connecting multiple asyn-
chronous RS-232/422/485 serial devices to an Ethernet network.
The two Ethernet ports allow the EKI-152X series to establish two separate Ethernet
connections to two Ethernet domain or two Ethernet Switches in the same domain.
Through dual Ethernet connections, the EKI-152X series greatly improves the device
connectivity reliability, increase system stability, and simplify the redundant configura-
tion.
By encapsulating serial data and transporting it over Ethernet, the EKI-152X series
allows virtual serial links over Ethernet and IP (TCP/IP, UDP/IP) networks. After
Advantech Serial Device Server Configuration Utility installation, standard serial
operation calls are transparently redirected to the serial device servers, guaranteeing
compatibility with legacy serial devices and enabling backward compatibility with
existing software. EKI-152X series also supports serial tunneling, allowing two native
serial devices to communicate over a network without any hosts and programming.
As a result, you can extend limited distance, point-to-point, direct serial connections
within the plant, throughout the factory, the facility, the office building, or across the
global enterprise.
The EKI-152X series provides an impressive list of features and functions enabling
multiple industrial devices to be connected, controlled, configured, managed, and
updated over a network. With serial ports and two auto-sensing Ethernet ports, the
EKI-152X series can easily connects multiple serial devices to a network.
The transmission speed of the EKI-152X series is up to 1.2M bps totally outstripping
the competition to meet the demand for high-speed exchange. Functionally transpar-
ent and efficient, the EKI-152X series is especially designed for remotely controlling
and monitoring devices via the Internet.
Types of supported devices:
 Human Machine Interface (HMI)
 Programmable Controller(PLC)
 Flow meters
 Temperature / pressure monitoring equipment
 Gas leak detection device
 Scales
 Power monitoring equipment
 Data Acquisition Modules
EKI-152X series provides various TCP/UDP operations: COM port redirection (Virtual
COM port), TCP server/ client and UDP mode. Serial devices can be connected by
means of multi-access modes.
