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. Figure 2.1 Dual Ethernet Connections EKI-1361/EKI-1362 User Manual 8 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. 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. 9 EKI-1361/EKI-1362 User Manual Getting Started 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 2.1.2 COM Port Redirector (Virtual COM Port) 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 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 2.1.3 TCP Server Mode Getting Started 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 a maximum of 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.

For more detailed information for setting, please refer to chapter 3.4 and chapter 3.5. 5.6.1 Basic Port Configuration EKI-1361/EKI-1362 User Manual 48 Baud Rate User can choose the regular baud rate from the drop down list or key in any particular baud rate manually. Parity The EKI serial device server provides five options for parity: None, Odd, Even, Space, and Mark. Data Bits The EKI serial device server provides four options for data bits: 5, 6, 7, and 8. Stop Bits The EKI serial device server provides three options for stop bits: 1, 1.5, and 2. Flow Control The EKI serial device server provides four options for flow control: None, XON/ XOFF, RTS/CTS, and DTR/DSR. 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 applications. 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 conection between host and serial device by mapping the IP of the EKI-152X series serial 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. 49 EKI-1361/EKI-1362 User Manual Web-Based Configuration Type The EKI-152X series serial device server offers three kinds of serial interfaces, RS-232, RS-485 and RS-422. User can use any of the three serial interfaces according to user's requirements. Chapter 5 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 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 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 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 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 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 "RoundRobin mode". Each serial port supports up to five simultaneous connections, so multiple hosts can transmit/receive data to/from the same serial port simultane- EKI-1361/EKI-1362 User Manual 50 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 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. 51 EKI-1361/EKI-1362 User Manual Web-Based Configuration 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. Chapter 5 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 acknowledgement via response timeout. When EKI device 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 device can transmit 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 communication is completed and continue the next host's query. This is an efficient way to reduce the waiting time and improve the performance. 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: 102465533. 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 device 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 device does not receive data over an established 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 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 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 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 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 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. EKI-1361/EKI-1362 User Manual 52 Data Pack Data pack means you can set condition of receiving data from serial port to be a package according to your application. There are four options to set the data packing: by data size (Byte), by time interval (ms), by character timeout (4 Bytes), or by end of character. 53 EKI-1361/EKI-1362 User Manual Web-Based Configuration Round-Robin Mode Enabling "Response Timeout" parameter, the EKI device 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 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 acknowledgement via response timeout. When EKI device 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 device can transmit 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 communication is completed and continue the next host's query. This is an efficient way to reduce the waiting time and improve the performance. Auto Connect Peer IP If enabling this option, EKI device will connect to TCP/IP which are set at Peers page automatically after boot up. 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 (including local port and peer port) of network devices which you want to connect. Chapter 5 5.6.2.3 USDG Control Mode In controlling mode, the EKI device 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 device 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 USDG Data 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 device, 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: <Guard Time>+++<Guard Time> Control Mode is designed for use with legacy operating systems, such as MSDOS, that do not support TCP/IP Ethernet. By connecting one of EKI's serial ports to the MS-DOS computer's serial port, it is possible to use legacy software originally designed to transmit data via modem, but now transmit the data over the Ethernet. Dial-in (Use TCP connect to serial port of EKI) EKI listens for a TCP/IP connection request from the remote host. when a TCP connection is coming, there will have prompt string "RING" shows on serial port site. After the system prompting the "RING" string, user can use "ATA" command to accept the connection or just ignore it. After accepted the connection, EKI will enter data mode. Dial-out (From serial port connect to specific TCP host target) User can user the AT Command "ATD <IP>#<TCP port>" to connect to a specific TCP target host from serial port. when the TCP connection is accepted by the remote host, EKI will show "CONNECT" string to serial port and enter data mode. EKI-1361/EKI-1362 User Manual 54 The "+++" command cannot be divided. The "+" character can be changed in Hang-up Character, and the guard time, which prefixes and suffixes the "+++" in order to protect the raw data, can be changed in Guard Time (ms). See picture. AT Commands EKI supports the following common AT commands used with a typical modem: AT command Description ATA Answer ATD Dial up the IP address#Port No. ATE ATE0=Echo OFF ATE1=Echo ON (default) ATH On-hook ATZ Reset and Recall user's settings AT&F Restore factory's Default settings Example 1 (Local connect to remote) 55 EKI-1361/EKI-1362 User Manual Web-Based Configuration Note! Chapter 5 Disconnect from serial port When EKI is in data mode, user can type the hangup character triple times, such as "+++". EKI will shut down the TCP connection and back to command mode, and shows "NO CARRIER" to indicate the connection has been shut down. Disconnect from remote TCP connection When EKI shows "NO CARRIER" on serial port, it means the TCP connection has been shut down. EKI will back to command mode automatically. Example 2 (Remote connect to local) 5.7 Monitor You can monitor the serial ports settings, statistic, and the connected IP address by click on Monitor function on the main menu. EKI-1361/EKI-1362 User Manual 56 Chapter 5 You can set the e-mail server and SNMP Trap server in the Setting page, and set the event type in the Event page. 5.8.1 E-mail Alert Consult your ISP or Network Administrator for the proper SMTP mail server settings. The auto warning functions may not work properly without proper settings. 57 EKI-1361/EKI-1362 User Manual Web-Based Configuration 5.8 Auto Warning (Alarm) 5.8.2 SNMP Trap You need to set the proper IP address of SNMP Trap Server. And choose the Trap Version; there are "SNMP v1" and "SNMP v2c" options. 5.8.3 System Event Cold Start This refers to starting the system from power off. When performing a cold start, the EKI device will send an e-mail, or send a SNMP trap after success rebooting. Warm Start This refers to restarting the system without turning the power off. When performing a warm start, the EKI device will send an e-mail, or send a SNMP trap after restarting the system. Authentication failure The user types a wrong password from Console or Administrator. When authentication failure occurs, the EKI device will send an e-mail, or send a SNMP trap. IP Change The user changes the EKI device's IP address. When the IP address changes, the EKI device will send an e-mail, or send a SNMP trap after restarting the system. Password Change The user changes the EKI device's password. When the password changes, the EKI device will send an e-mail, or send a SNMP trap after restarting the system. Ethernet 1 Down The Ethernet 1 port has link failure condition. When the Ethernet 1 links fail, the EKI device will send an e-mail, or send a SNMP trap immediately. Ethernet 2 Down The Ethernet 2 port has link failure condition. When the Ethernet 2 links fail, the EKI device will send an e-mail, or send a SNMP trap immediately. EKI-1361/EKI-1362 User Manual 58 Note! All new configurations will take effect after rebooting. The reboot function is located on the main menu of the Web Configuration. 5.9 Change Password You can change the serial device server password on here: If you have set a password via the configuration utility or Telnet or serial console, when you access the web configuration, you need to key in the password. Do not need to enter the user name in the dialog. 59 EKI-1361/EKI-1362 User Manual Web-Based Configuration DCD Change The DCD (Data Carrier Detect) signal has changed, also indicating that the modem connection status has changed. For example, a DCD change to high also means "Connected" between local modem and remote modem. If the DCD signal changes to low, it also means that the connection line is down. When the DCD signal changes, the EKI device will send an e-mail, or send a SNMP trap. DSR Change The DSR (Data Set Ready) signal has changed, also indicating that the data communication equipment's power is off. For example, a DSR change to high also means that the DCE is powered ON. If the DSR signal changes to low, it also means that the DCE is powered off. When the DSR signal changes, the EKI device will send an e-mail, or send a SNMP trap. Chapter 5 5.8.4 Serial Port Event If you want to disable the password protection, just change the password to the default "None" (leave the new password column blank), Be sure to press the "Save" button and reboot the serial device server to make the change effective. 5.10 Import/Export Device Settings You can Import or Export the serial device server all setting as the ".conf" file format.
