1 Overview

1.1 Introduction

Advantech's EKI-1300 series of Industrial Device Servers are a robust, feature-rich,
and cost effective way to network-enable equipment in an industrial automation envi­ronment. The EKI-1361/1362 provides one or two serial ports, 802.11b/g/n wireless
LAN interface to connect any RS-232/422/485 devices to wireless LAN. These wire­less serial device servers provide serial-to-wireless network connectivity as an alter­native to wired Ethernet connectivity and enable virtually any serial device or
equipment to be remotely accessed, controlled, monitored, or shared on an 802.11b/
g/n wireless network.

By encapsulating serial data and transporting it over Ethernet, the EKI-1361/1362
allows virtual serial links over Ethernet IP-based networks. After Advantech Serial
Device Server Configuration Utility installed, standard serial operation calls with vir­tual COM port could be transparently redirected to the serial device servers, guaran­teeing compatibility with legacy serial devices and enabling backward compatibility
with existing software. EKI-1361/1362 also supports serial tunneling, allowing two
native serial devices to communicate over a network without any hosts or 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-1361/1362 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 802.11b/g/n wireless LAN, the EKI­1361/1362 can easily connects multiple serial devices to a network. The transmission
speed of the EKI-1361/1362 is up to 921.6 Kbps totally outstripping the competition to
meet the demand for high-speed exchange. Functionally transparent and efficient,
the EKI-1361/1362 is especially designed for remotely controlling and monitoring
devices via the Internet.

The EKI-1361/1362 provides roaming ability. EKI-1361/1362 can midgrate from AP to
AP during certain condition. In some field applications, the device can't use a fixed
physical connection, such as AGV, transportation, and cross wide space communica­tion. EKI-1361/1362 can easily installed to fulfill this requirement. With compact size
and lightweight design, EKI-1361/1362 could be installed onto the moving vehicle
without much extra loading.

2 Getting Started

2.1 Understanding EKI-1361/EKI-1362

The EKI-136X series are wireless-based, serial device servers for connecting RS­232/422/485 devices to a TCP/IP network. Once connected through EKI series, the
serial device will be able to send and receive data on a network like any other net­work device. It extends traditional 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 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 series is designed to network-enable any RS-232/422/485 serial device and
provide industry-grade hardware and easy-use software to make connecting 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 series features a lot of powerful functions such as: high speed data transfer,
access-control, auto-detection of all EKI series products, remote connection 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-1361/EKI-1362 User Manual 8

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 4096 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.

Chapter 2 Getting Started

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.

Figure 2.2 COM Port Redirector

9 EKI-1361/EKI-1362 User Manual

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.

EKI-1361/EKI-1362 User Manual 10

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. 5 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

Chapter 2 Getting Started

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 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

11 EKI-1361/EKI-1362 User Manual

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 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 series connecting or disconnecting
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.
