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 envi-

ronment. 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 wire-

less serial device servers provide serial-to-wireless network connectivity as an alter-

native 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 vir-

tual COM port could be transparently redirected to the serial device servers, guaran-

teeing 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 program-

ming. As a result, you can extend limited distance, point-to-point, direct serial con-

nections 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 EKI-

1361/1362 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 communica-

tion. 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.

2.1 Understanding EKI-1361/EKI-1362

The EKI-136X series are wireless-based, serial device servers for connecting RS-

232/422/485 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 net-

work device. It extends traditional COM ports of a PC with access over a TCP/IP net-

work. 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 immedi-

ately 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 dif-

ferent 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.

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 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.

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-1361/EKI-1362 User Manual 10

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.

11 EKI-1361/EKI-1362 User Manual

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. 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

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 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-1361/EKI-1362 User Manual 12

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.

virtual COM ports and provides access to serial devices connected to Advantech

serial device servers. Your serial device applications can communicate with serial

devices connected to Advantech serial device servers without software changes.

Since the virtual COM ports work like standard Windows COM ports, your application

software sees no difference between a local serial device and one connected to a

Advantech serial device server.

COM redirector utility and Virtual COM port Management utility are integrated into

one utility with same GUI. Advantech Serial Device Server Configuration Utility can

create all Virtual COM ports using “Auto Mapping” function. You can map the Virtual

COM port by yourself.

Auto Reconnect Property

Sometimes, the connection between Advantech serial device server and HOST is

interrupted by network traffic or powered-off by accident. In such a situation, the host

has to reconnect to Advantech serial device server. The function "Auto Reconnect" is

for this purpose, if the Advantech serial server loses the connection to its host, the

COM redirector will try to re-establish the connection while the host’s AP access the

virtual COM port. The COM redirector DOES NOT re-establish the connection auto-

matically. When the connection is working again, the host's commands will be auto-

matically received by the Advantech serial device server again. Reconfiguration is

not necessary, so this function enhances the reliability of the system.

If the function is disabled, the connection can not be re-established again unless the

COM redirector or host is restarted.

Serial device server has two Ethernet ports. You can select two Ethernet port to

establish two Ethernet connections with one virtual COM port. It means that COM

redirector will use one connection with the COM port on device server to

communicate. If this connection failed, COM redirector will establish another Ethernet

connection to communicate with device. The switch time will be 3 seconds ~ 5

seconds depending on the network traffic and host status.

If you don’t use the redundant function, just select the correct IP address in the IP

address 1 field.

Note If you set the wrong IP address, COM redirector will still try to connect the

device. It might cause the system performance low or other issue.

5.6.2 Operation Mode

5.6.2.1 Virtual COM Mode

The EKI serial device server extends traditional COM ports of a PC to Ethernet

access. Through Ethernet networking, users can control and monitor remote serial

devices and equipment over LAN or WAN. The EKI device server comes with a COM

port redirector (Virtual COM driver) that transmits all serial signals intact. This means

that your existing COM-based software can be preserved, without modifying to fulfill

the needs. The Virtual COM mode allows user to continue using RS-232/422/485

serial communications software that was written for pure serial communication appli-

cations.

The EKI series comes with COM port redirector (virtual COM driver) that work with

Window 2000/XP/Vista(X86) systems. The driver establishes a transparent con-

EKI-1361/EKI-1362 User Manual 50

nection between host and serial device by mapping the IP of the EKI-152X seriesse-

rial device server serial port to a local COM port on the host computer.

The EKI series provides Multi-access function through Ethernet connection path.

Allow the maximum of 5 connections to open one serial port simultaneously. In this

mode, all connection has to use the same serial setting. If one serial setting of these

connections is different from others, the data communication may operate incorrectly.

Host Idle Timeout

The “Host Idle Timeout” setting monitors the connection between the host and

the device. If the “Host Idle Timeout” setting time is reached, the device server

will release the resources allocated to the port mapping. This prevents a stalled

host from affecting the connective device.

The EKI device provides Multi-access function through Ethernet connection

path. Allow the maximum of 5 connections to open one serial port simultane-

serial setting of these connections is different from others, the data communica-

tion may operate incorrectly.

There are two operating mode of Multi-access function. One is Normal mode;

another is Round-Robin mode.

Normal mode

Disabling “Response Timeout” parameter, the EKI device will operate in “normal

mode”. When multiple hosts open the serial port simultaneously, the EKI device

only offers control ability for the first connected host and provides data commu-

nication function for others. Each serial port supports up to five simultaneous

connections, so multiple hosts can transmit/receive data to/from the same serial

port simultaneously. Every host can transmit data to the same serial port, and

the EKI device will also transmit data to every hosts. When the multiple hosts

transmit data to the same serial port at the same time, the received data from

Chapter 5 Web-Based Configuration

Ethernet and the outputs of serial port are mixed. When the EKI device receives

data from serial port, the data will also be transmitted to the connected hosts

simultaneously.

Round-Robin mode:

Enabling “Response Timeout” parameter, the EKI device will operate in “Round-

Robin mode”. Each serial port supports up to five simultaneous connections, so

multiple hosts can transmit/receive data to/from the same serial port simultane-

ously. Every host can transmit data to the same serial port simultaneously, but

the EKI device will process the data communication in order. The EKI device will

process the first host’s request and reply the response to the first host. The EKI

device serial device server can determine the end of the serial acknowledge-

ment via response timeout. When EKI device serial device server receives noth-

ing from serial port after the setting of response timeout, the device will reply the

acknowledgement to the host and then process the next host’s request. While

the connected hosts are more and “Response Timeout” is long, the process

time is much longer.

Frame Break is a very import parameter for Round Robin mode. This parameter

is the smart way to reduce inefficient waiting time and the EKI device can trans-

mit data more efficiently. Disabling the Frame Break function, the EKI device will

wait “Response Timeout” period, whether the device have transmitted the data.

During this period, the commands from hosts will be queued and the EKI device

just processes this command. Enabling “Frame Break”, if the serial port idle is

longer than the “Frame Break” period, the EKI device will assume the communi-

cation is completed and continue the next host’s query. This is an efficient way

to reduce the waiting time and improve the performance.

5.6.2.2 Data Mode (USDG Mode)

The EKI device can be Data server or Data client either. Both operations support

TCP and UDP protocol. The EKI device makes your serial devices behave just like

networking devices. You can issue commands or transmit data from serial devices,

which connected to the EKI device, to any devices that are connected to the Internet.

The EKI device allows most 5 host PCs accessing data simultaneously via polling

networking architecture. You can use it according to your application. If you want to

access the EKI device, you must ascertain your application software supports stan-

dard networking application programming interface (API) such as: WinSock Socket.

You might select “USDG Mode” as the following figure to change the mode of the port

to TCP server/client or UDP mode.

EKI-1361/EKI-1362 User Manual 52

Protocol

The EKI device provides TCP/IP and UDP two protocols. In settings, you can

choose either TCP mode or UDP mode according to your application.

Data Listen Port

The TCP/UDP port number represents the source port number, and the number

is used to identify the channel for remote initiating connections. Range: 1024-

65533. If an unknown caller wants to connect to the system and asks for some

services, they need to define the TCP/UDP port to carry a long-term conversa-

tion. Each node on a TCP/IP network has an IP address, and each IP address

can allow connections on one or more TCP port. The well known TCP ports are

those that have been defined; for example, port 23 is used for Telnet connec-

tions. There are also custom sockets that users and developers define for their

specific needs. The default TCP/UDP port of the EKI device is 5300. The exam-

ple initial 5300 is System Port, and 5301 is Data Port. But users can adjust them

by one's preference or application.

Each port has its own data listen port to accept connected request of other net-

work device. So, the data listen port can’t be set the same value. You can trans-

mit/receive data to/from device via the data listen port.

Command Listen Port

Each port has its own command listen port to accept connected request of other

network device. So, the command listen port can’t be set the same value. You

can use ‘AT command’ to change the port setting via the command listen port.

The Command Listen Port should be different from the Data Listen port.

Data Idle Timeout

The default is 60 seconds. If you want to keep connection continually, you can

disable the Data Idle Timeout. Data idle Time is the time period in which the

device waits for data. If the EKI device does not receive data over an estab-

lished idle time, the EKI device will disconnect temporarily. When the data

comes to the EKI device, it will reconnect automatically. Users do not need to

reconnect.

Enable Time Sharing

The EKI device provides Multi-access function through Ethernet connection

path. Allow the maximum of 5 connections to open one serial port simultane-

ously. In the mode, all connection has to use the same serial setting. If one

serial setting of these connections is different from others, the data communica-

tion may operate incorrectly.

There are two operating mode of Multi-access function. One is Normal mode;

another is Round-Robin mode.
