Introduction

1.1 Overview

This manual provides the necessary information to use the EKI-1528 and EKI-1526. The Advantech EKI-1500 series of serial device servers consist of fast and cost-effective device servers between serial RS-232/422/485 and Ethernet interfaces.

The two Ethernet ports allow the EKI-1528/1526 to establish two separate Ethernet connections to two Ethernet domains or switches in the same domain. Through dual Ethernet connections, the EKI-1528/1526 greatly improves the device connectivity reliability, increases system stability, and simplifies redundant configuration.

By encapsulating serial data and transporting it over Ethernet, the EKI-1528/1526 allows virtual serial links over Ethernet and IP (TCP/IP, UDP/IP) networks. After Advantech Serial Device Server Configuration Utility (including COM port redirector driver) 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. The EKI-1528/1526 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-1528/1526 provides various operation modes including COM port redirector (Virtual COM port), TCP server mode, TCP client mode, and UDP mode. These units upgrade your existing device for integrating into the Internet world, and make your serial devices behave just like the networking devices.

The EKI-1528/1526 provides rich configuration methods: web browser console, Telnet console, serial interface console, and Windows utility. Each method ensures quick and effective installation. The EKI-1528/1526 also supports automatic IP configuration protocol including DHCP and BOOTP.

Getting Started

2.1 Understanding the EKI-1528/1526

The EKI-1528/1526 is network-based, serial device server for connecting RS-232/422/485 serial devices, such as PLCs, CNCs, scales, and scanners, directly to a TCP/IP network. Once connected through the EKI-1528/1526, the serial devices will be able to send and receive data on a network like any other network devices. 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-1528/1526 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.

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-1500 serial device servers. 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.

The EKI-1528/1526 provides dual Ethernet ports that can establish two physical Ethernet connections. Dual connections enable 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.

2.1.1 COM Port Redirector (Virtual COM)

Advantech serial device server configuration utility is a serial COM port redirector that creates virtual COM ports and provides access to the serial devices connected to Advantech serial device servers. 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 to 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.

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.

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 same serial device, you can employ EKI-1500 serial device servers that provide a virtual COM port for a host or multi-hosts on an Ethernet network. EKI-1500 serial device server is located between hosts and serial devices. Each serial port on the EKI-1500 serial device server can allow the maximum of 5 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; the EKI-1500 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; the EKI-1500 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.

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.

2.1.3 TCP Client (Data Mode)

In the TCP Client mode, the TCP connection will be established from the EKI-1500 serial device server. This operation mode supports a max. of 16 simultaneous connections for each serial port on the EKI-1500 serial device servers to one host or several hosts. You should configure the IP address and TCP port number of the network hosts which the EKI-1500 serial device server connect to using Advantech Serial Device Server Configuration Utility. After configuration, when EKI-1500 serial device server receives the data from serial port, the device server will employ the connection to hosts which are configured.

2.1.4 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.

2.1.6 Control Mode

In the control mode, the EKI-1500 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 the control mode.

The control mode provides three kinds of modem AT-style commands. The serial devices can use these commands to control the EKI-1500 serial device server 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.

Delay Time (ms)

When you enable the delay time, the serial port will postpone the received data for the time interval you set, and then send the received data to the TCP/IP network.

Ignore Purge

Some application program will purge the serial port while it is the first time opens this serial port. You can ignore the purge command by enable this option.

Disable Character Timeout Detection

Enable this option will disable the serial port character timeout detection.

Disable Multiple Connection

Enable this option will disable the multi-access function, thus the only one TCP connection is allowed on this serial port.

Note! These settings are just for some special application cases. We recommend do not enable the advanced settings in normal usage.

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-1528/1526 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-1528/1526 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-1528/1526 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-1528/1526 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-1528/1526 will operate in "normal mode". When multiple hosts open the serial port simultaneously, the EKI-1528/1526 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 EKI-1528/1526 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-1528/1526 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-1528/1526 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-1528/1526 will process the data communication in order. The EKI-1528/1526 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.

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-1528/1526 can transmit data more efficiently. Disabling the Frame Break function, the EKI-1528/1526 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-1528/1526 just processes this command. Enabling "Frame Break", if the serial port idle is longer than the "Frame Break" period, the EKI-1528/1526 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-1528/1526 can be Data server or Data client either. Both operations support TCP and UDP protocol. The EKI-1528/1526 makes your serial devices behave just like networking devices. You can issue commands or transmit data from serial devices, which connected to the EKI-1528/1526, to any devices that are connected to the Internet.

The EKI-1528/1526 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-1528/1526, you must ascertain your application software supports standard 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.

Protocol

The EKI-1528/1526 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-1528/1526 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.

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-1528/1526 does not receive data over an established idle time, the EKI-1528/1526 will disconnect temporarily. When the data comes to the EKI-1528/1526, it will reconnect automatically. Users do not need to reconnect.

Enable Time Sharing

The EKI-1528/1526 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-1528/1526 will operate in “normal mode”. When multiple hosts open the serial port simultaneously, the EKI-1528/1526 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 EKI-1528/1526 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-1528/1526 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-1528/1526 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-1528/1526 will process the data communication in order. The EKI-1528/1526 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.

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-1528/1526 can transmit data more efficiently. Disabling the Frame Break function, the EKI-1528/1526 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-1528/1526 just processes this command. Enabling "Frame Break", if the serial port idle is longer than the "Frame Break" period, the EKI-1528/1526 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.

Peer Number

Set the number of network device which you want to connect. You can set maximum sixteen network devices which you want to connect. You need to fill out the IP Address and Port of network devices which you want to connect.

3.5.3 Control Mode (USDG Mode)

In controlling mode, the EKI-1528/1526 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-1528/1526 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-1528/1526, 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.

Guard Time

The default value is 1000 ms.

Example: + + +

The following commands are available for EKI-1528/1526.

The COM ports in the "Virtual Com Ports" listing are now available for use by Windows applications.

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

Select the serial port on the serial device server and the host COM that you want to map. Press

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 does not be re-established again unless the COM redirector or host is restarted.

Dual Ethernet Redundancy

The EKI-1500 serial device sever 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.

4.1.3 Manual Direct Mapping Virtual COM Port

Click the button on the Quick Took bar, you can add a target by selecting the

Device Type and inputting the IP address without physically connecting the serial device server to the network.

4.1.4 Remove the Virtual COM Port

If you want to remove the virtual COM port, you can remove them one by one or group remove ports.

Individual Remove

Right click on COM port you have mapped before and select "Remove This Port".

Group Remove Port

Right click on Virtual Com Ports on Device Server List Area and select "Group Remove Port", you can choose which ports you want to remove.

4.2 Running Diagnostic Test

The purpose of this test is to make sure the communication from host PC to serial device server is OK. If there is still an error, you can check the communication from the EKI-1500 serial device server to the devices.

If the test is selected, an external test will be done to check that the connection signals for each port are working properly. For the test, you will need to connect each port to a loopback tester (provided in the package). The loopback test only applies to RS-232 mode. The test is divided into two parts: Signal test and Communication Parameters test.

Note! Before you do this diagnostic test, you must complete the process of virtual COM port mapping (which is described in chapter 4.1).

Click "Simple Serial Test" on the Tools menu,

Select which COM port you want to run diagnostic test, and then press "Test" button to process the testing.

Signal Test

■ RTS -> CTS: check the RTS and CTS signal between two ports
■ DTR -> RI: check the DTR and RI signal between two ports
■ DTR -> DSR: check the DTR and DSR signal between two ports
■ DTR -> DCD: check the DTR and DCD signal between two ports

Communication Parameters Test

■ Baud rate: 50bps \~ 921.6kbps

Data bit: 5, 6, 7, 8

■ Stop bit: 1, 1.5, 2

■ Parity: Odd, Even, None, Space, Mark

When the test is finish, it will show the test result, the click "Exit" button to return to the utility window.
