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.

2.1 Understanding EKI-152X series
The EKI-152X series are network-based, serial device servers for connecting RS-
232/422/485 devices, such as CNCs, PLCs, scales, and scanners, directly to a TCP/
IP network. Once connected through EKI-152X series, the serial device will be able
to send and receive data on a network like any other network device. It extends tradi-
tional COM ports of a PC with access over a TCP/IP network. Through networking,
you can control and monitor remote serial devices either over a LAN or over the
WAN. Since the EKI-152X series is connected through a TCP/IP network, you might
need to know some basic facts about networking in order to get the server hooked up
correctly.
2.1.1 Product Description
The EKI-152X series is designed to network-enable any RS-232/422/485 serial
device and provide industry-grade hardware and easy-use software to make con-
necting serial devices to an Ethernet network a surprisingly simple process. These
units immediately upgrade your existing serial devices for integration into the Internet
world. The EKI-152X series features a lot of powerful functions such as: high speed
data transfer, access-control, auto-detection of all EKI series products, remote con-
nection from different network domain, remote firmware download, and more.
After the simple installation steps to attach your network and serial device to the
appropriate connectors on the serial device servers and driver installation, you will
then be able to communicate with the serial devices via its own application software
and with the EKI serial device server. COM port redirector, TCP server mode, TCP
client mode, UDP server mode, UDP client mode and Control mode are all different
schemes to make a serial connection across using one or more Serial device server.
EKI-152X series provides dual Ethernet ports that can establish two physical Ether-
net connections. Dual connection control enables an alternative backup session that
host can connect to device server by the way of second connection while the primary
connection should be lost or dropped.

Chapter 2 Getting Started
2.1.2 COM Port Redirector (Virtual COM Port)
Advantech Serial Device Server Configuration Utility is a serial COM port redirector
that creates virtual COM ports and provides access to serial device connected to
Advantech serial device server. You can configure the serial device server and
enable the Virtual COM port using one integrated utility. Advantech Serial Device
Server Configuration Utility allows you to configure Microsoft applications to
communicate with network enabled serial device servers as easily as if they were
physically installed in or directly connected on the PC.
The Advantech redirector can create up to 255 virtual COM ports. Application on the
host can open virtual COM port to access the serial device servers at the same time.
The redirector will handle each active virtual COM port as a separate TCP
connection to Advantech serial device servers.
Figure 2.2 COM Port Redirector
2.1.2.1 Normal Mode
The Advantech redirector connects the Advantech serial device servers while an
application open the COM port and disconnects from the Advantech serial device
servers when the application closes the COM port. The redirector uses TCP network
connections to the Advantech serial device server to gain the access to the
connected serial devices.

EKI-1521/1522/1524 User Manual 8
2.1.2.2 Multi-Access Mode (Shared COM port mode)
Most of serial devices are connected directly and physically to the PC serial ports via
a cable. The operation system, ex. Windows XP, provides the COM ports that user’s
application can access, and control the serial device through the serial cable. This
means that the serial device can be connected to one host and only one application
on this host can handle input, output and control operation on this device.
If you want to run more than one applications to use a serial device, you can employ
EKI serial device servers that provide a virtual COM port for a host or multi-hosts on
an Ethernet network. EKI serial device server is located between hosts and serial
devices. Each serial port on the EKI serial device server can allow max. five host
connections through one Ethernet port or two Ethernet ports. There are two major
operation modes for Multi-Access Mode. First one is broadcast mode; EKI serial
device server handles a command from one application and replies the data from the
serial port to all applications that are connecting this serial port. Another one is polling
mode; EKI serial device server handles the command from one application and reply
to this application only. Query from other applications must be queued and wait for
current process completing.
Figure 2.3 Multi-Access Mode
By using a serial derive server to share serial device, you eliminate the separate
serial lines and serial devices that can be attached to individual hosts. Collecting the
data from these serial devices become more easily and more effectively.

Chapter 2 Getting Started
2.1.3 TCP Server Mode
In TCP server mode, you might initiate the TCP connection from host to EKI serial
device server. This operation mode support max. five simultaneous connections for
each serial port on EKI serial device server from one host or several hosts, however
multi-hosts collect the data from one serial port at the same time
Figure 2.4 TCP Server Mode
2.1.4 TCP Client Mode
In TCP Client mode, the TCP connection will be established from EKI serial device
server. This operation mode supports max.16 simultaneous connections for each
serial port on EKI-152X series to one host or several hosts. You should configure the
IP address and TCP port number of the network hosts which the EKI serial device
server connect to using Advantech Serial Device Server Configuration Utility. After
configuration, when EKI serial device server receives the data from serial port, the
device server will employ the connection to hosts which are configured.
Figure 2.5 TCP Client Mode

EKI-1521/1522/1524 User Manual 10
2.1.5 Serial Tunneling Mode
Two native serial devices can communicate over an Ethernet network without any
intermediate host PC and software programming. Serial Tunneling is very simple to
use. You can use Advantech Serial Device Server Configuration Utility to designate
one serial port as the tunneling master and another serial device server port as the
tunneling slave.
Figure 2.6 Serial Tunneling Mode
2.1.6 UDP Server/Client Mode
UDP is used primarily for broadcasting messages over a network. In the UDP server
mode, EKI-152X series access max. 8 hosts’ UDP message. In the UDP client mode,
EKI serial device servers transmit UDP message to max. 16 hosts simultaneously.
2.1.7 Control Mode
In controlling mode, the EKI serial device server presents a modem interface to the
attached serial device: it accepts AT-style modem commands to connect / disconnect
to other networking device. If you want serial device running application program to
connect/disconnect to different devices by request, you can use controlling mode.
The controlling mode provides three kinds of modem AT-style commands. The serial
devices can use these commands to control EKI-152X series connecting or discon-
necting to remote networking devices. Thus intelligent serial devices such as stand-
alone PLC will send /receive data to/from devices one by one via Ethernet.
