2 Getting Started

2.1 Understanding EKI-1521/1522/1524

The EKI-1521/1522/1524 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-1521/1522/1524, 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-1521/1522/1524 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-1521/1522/1524 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-1521/1522/1524 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-1521/1522/1524 provides dual Ethernet ports that can establish two physical
Ethernet 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.

Figure 2.1 Dual Ethernet Connections

EKI-1521/1522/1524 User Manual 6

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.

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

7 EKI-1521/1522/1524 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-1521/1522/1524 User Manual 8

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

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-1521/1522/1524 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

9 EKI-1521/1522/1524 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-1521/1522/1524 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-1521/1522/1524 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.

3.5 Operation Mode Settings

3.5.1 Virtual COM Mode

The EKI-1500 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 equipments over LAN or WAN. The EKI-1500 series 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 appli­cations.

The EKI-1500 series comes with COM port redirector (virtual COM driver) that work
with Window 2000/XP/Vista(X86) systems. The driver establishes a transparent con­nection between host and serial device by mapping the IP of the EKI-1500 serial
device server serial port to a local COM port on the host computer.

The EKI-1500 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-1500 series provides Multi-access function through Ethernet connection
path. Allow the maximum of 5 connections to open one serial port simultaneously. 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 communication may operate
incorrectly.

EKI-1521/1522/1524 User Manual 32

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-1500 series will operate in “normal
mode”. When multiple hosts open the serial port simultaneously, the EKI-1500 series
only offers control ability for the first connected host and provides data communica­tion 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, an
1500 series 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 Ethernet and
the outputs of serial port are mixed. When the EKI-1500 series 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-1500 series 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 simultaneously.
Every host can transmit data to the same serial port simultaneously, but the EKI-1500
series will process the data communication in order. The EKI-1500 series will process
the first host’s request and reply the response to the first host. The EKI-1500 serial
device server can determine the end of the serial acknowledgement via response
timeout. When EKI-1500 serial device server receives nothing 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.

d the EKI-

Chapter 3 Configuration

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-1500 series can transmit
data more efficiently. Disabling the Frame Break function, the EKI-1500 series 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-1500 series just
processes this command. Enabling “Frame Break”, if the serial port idle is longer
than the “Frame Break” period, the EKI-1500 series will assume the communication
is completed and continue the next host’s query. This is an efficient way to reduce the
waiting time and improve the performance.

3.5.2 Data Mode (USDG Mode)

The EKI-1500 series can be Data server or Data client either. Both operations sup­port TCP and UDP protocol. The EKI-1500 series makes your serial devices behave
just like networking devices. You can issue commands or transmit data from serial
devices, which connected to the EKI-1500 series, to any devices that are connected
to the Internet.

The EKI-1500 series 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-1500 series, you must ascertain your application software supports
standard networking application programming interface (API) such as: WinSock
Socket.

33 EKI-1521/1522/1524 User Manual

You might select “USDG Mode” as the following figure to change the mode of the port
to TCP server/client or UDP mode.

Protocol

The EKI-1500 series 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 conversation.

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 connections. There are also
custom sockets that users and developers define for their specific needs. The default
TCP/UDP port of the EKI-1500 series is 5300. The example 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 network
device. So, the data listen port can’t be set the same value. You can transmit/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.

EKI-1521/1522/1524 User Manual 34

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-1500 series does not receive data over an established idle
time, the EKI-1500 series will disconnect temporarily. When the data comes to the
EKI-1500 series, it will reconnect automatically. Users do not need to reconnect.

Enable Time Sharing

The EKI-1500 series provides Multi-access function through Ethernet connection
path. Allow the maximum of 5 connections to open one serial port simultaneously. 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 communication 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-1500 series will operate in “normal
mode”. When multiple hosts open the serial port simultaneously, the EKI-1500 series
only offers control ability for the first connected host and provides data communica­tion 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 EKI­1500 series 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 Ethernet and
the outputs of serial port are mixed. When the EKI-1500 series receives data from
serial port, the data will also be transmitted to the connected hosts simultaneously.

Chapter 3 Configuration

Round-Robin Mode

Enabling “Response Timeout” parameter, the EKI-1500 series will operate in “Round­Robin mode”. 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 simultaneously, but the EKI-1500

3.5.3 Control Mode (USDG Mode)

In controlling mode, the EKI-1500 series 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 dynamically, you can use controlling mode.

The “Control mode” provides three kinds of modem AT-style commands. The serial
devices can use these commands to control the EKI-1500 series to connect/discon­nect to remote networking device. Thus, intelligent serial devices such as standalone
PLC will send /receive data to/from devices one by one via Ethernet.

Please refer to the Data Mode (USDG Mode) to setup the Data Listen Port, Com­mand Listen Port, and Data Idle Timeout.

Hangup Character

The default character is “+”. After you have connected to another serial device via
EKI-1500 series, you may need to disconnect. Then you can use the command "+++"
to disconnect. To do this leaves your keyboard idle (don't press any keys) for at least
several seconds, then press "+" three times. You can set "Guard Time" to define the
idle time. Be sure that you have to press "+" over the idle time.

Redirector

4.1 Setting COM Redirector (Virtual COM port)

Advantech COM port mapping software is a serial COM port redirector that creates
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.

4.1.1 Auto Mapping

Right click the serial device name on the sub-tree of Device Server List area and
select the “Auto Mapping” function.

The serial ports that can be assigned to virtual COM will be shown in this window.
Select the serial ports you wish to map or click the <Select All> button and press
<Map Selected Ports> button. The selected serial ports will be mapped to virtual
COM ports in sequential order.

<Map it> to establish the virtual COM port on the host.

EKI-1521/1522/1524 User Manual 52

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 auto­matically. When the connection is working again, the host's commands will be auto­matically 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.

EKI-1521/1522/1524 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.

Chapter 4 Setting COM Redirector

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.
