Chapter 22Getting Started
EKI-1351/EKI-1352/EKI-1521/1522/1524 User Manual 82.1 Understanding Serial Device ServersThe EKI serial device servers are network-based, serial device servers for connect-ing four RS-232/422/485 devices, such as CNCs, PLCs, scales, and scanners,directly to a TCP/IP network. Once connected through EKI serial device servers,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/IPnetwork. Through networking, you can control an monitor remote serial deviceseither over a LAN or over the WAN. Since the EKI serial device servers areconnected through a TCP/IP network, you might need to know some basic factsabout networking in order to get the server hooked up correctly.2.1.1 Product DescriptionThe EKI serial device servers are designed to network-enable any RS-232/422/485serial devices and provide industry-grade hardware and easy-use software to makeconnecting serial devices to an Ethernet network a surprisingly simple process.These units immediately upgrade your exiting serial devices for integration into theInternet world. The EKI serial device server feature a lot of powerful functions suchas: high speed data transfer, access-control, auto-detection of all EKI seriesproducts, remote connection from different network domain, remote firmwaredownload, and more.After the simple installation steps to attach your network and serial device to theappropriate connectors on the serial device servers and driver installation, you willthen be able to communicate with the serial devices via its own application softwareand with the EKI serial device server. COM port redirector, TCP server mode, TCPclient mode, UDP server mode, UDP client mode and Control mode are all differentschemes to make a serial connection across using one or more Serial device server.EKI-1521, EKI-1522, and EKI-1524 provide dual Ethernet ports that can establishtwo physical Ethernet connections. Dual connection control enables an alternativebackup session that host can connect to device server by the way of second connec-tion while the primary connection should be lost or dropped.
9 EKI-1351/EKI-1352/EKI-1521/1522/1524 User ManualChapter 2 Getting StartedEKI-1351 and EKI-1352 has an 802.11b/g transceiver in addition to its serial andEthernet ports. Each serial port is connected to the serial communication port of adevice. The wireless transceiver connects to another wireless device or to an AccessPoint (AP). 2.1.2 COM port redirector (Virtual COM port)Advantech COM port mapping utility is a serial COM port redirector that createsvirtual COM ports and provides access to serial device connected to Advantechserial device server. Advantech COM port mapping utility is integrated withAdvantech serial device server configuration utility. You can configure the deviceserver and enable the Virtual COM port using one integrated utility. Advantech serialdevice server utility allows you to configure Microsoft applications to communicatewith network enabled device servers as easily as if they were physically installed in ordirectly connected on the PC.The Advantech redirector can create up to 255 virtual COM ports. Application on thehost 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 TCPconnection to Advantech serial device servers.
EKI-1351/EKI-1352/EKI-1521/1522/1524 User Manual 102.1.2.1 Normal ModeThe Advantech redirector connects the Advantech serial device server while anapplication open the COM port and disconnects from the Advantech serial deviceserver when the application closes the COM port. The redirector uses TCP networkconnections to the Advantech serial device server to gain the access to theconnected serial devices.2.1.2.2 Mutli-Access Mode (Shared COM port mode)Most of serial devices are connected directly and physically to the PC serial ports viaa cable. The operation system, ex. Windows XP, provides the COM ports that user’sapplication can access, and control the serial device through the serial cable. Thismeans that the serial device can be connected to one host and only one applicationon 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 employEKI serial device servers that provide a virtual COM pool for a host or multi-hosts onan Ethernet network. EKI serial device server is located between hosts and serialdevices. Each serial port on the EKI serial device server can allow max. of 5 hostconnections through one Ethernet port and two Ethernet ports. There are two majoroperation modes for Multi-Access Mode. First one is broadcast mode, EKI serialdevice server handles a command from one application and replies the data from theserial port to all applications that are connecting this serial port. Another one is pollingmode. EKI serial device server handles the command from one application and replyto this application only. Query from other applications must be queued and wait forcurrent process completing.
11 EKI-1351/EKI-1352/EKI-1521/1522/1524 User ManualChapter 2 Getting StartedBy using a serial derive server to share serial device, you eliminate the separateserial lines and serial devices that can be attached to individual hosts. Collecting thedata from these serial devices become more easily and more effectively. 2.1.3 TCP Server ModeIn TCP server mode, you might initiate the TCP connection from host to EKI serialdevice server. This operation mode support max. 5 simultaneous connections foreach serial port on EKI serial device server from one host or several hosts, howevermulti-hosts collect the data from one serial port at the same time.
EKI-1351/EKI-1352/EKI-1521/1522/1524 User Manual 122.1.4 TCP Client ModeIn TCP Client mode, the TCP connection will be established from EKI serial deviceserver. This operation mode supports maximum 16 (EKI-1521, EKI-1522, and EKI-1524) or maximum 4(EKI-1351 and EKI-1352) simultaneous connections for eachserial port on EKI serial device sever to one host or several hosts. You shouldconfigure the IP address and TCP port number of the network hosts which the EKIserial device connect to using Advantech serial device server utility. Afterconfiguration, when EKI serial device server receives the data from serial port, thedevice server will employ the connection to hosts which are configured.
13 EKI-1351/EKI-1352/EKI-1521/1522/1524 User ManualChapter 2 Getting Started2.1.5 Serial Tunneling modeTwo native serial devices can communicate over a Ethernet network without anyintermediate host PC and software programming. Serial Tunneling is very simple touse. You can use Advantech serial device server utility to designate one serial portas the tunneling master and another serial device server port as the tunneling slave. 2.1.6 UDP Server/Client ModeUDP is used primarily for broadcasting messages over a network. In the UDP servermode, EKI serial device server access max of 8 hosts’ UDP message. In the UDPclient mode, EKI serial device servers transmit UDP message to max of 16 hostssimultaneously.
EKI-1351/EKI-1352/EKI-1521/1522/1524 User Manual 142.1.7 Control ModeIn controlling mode, the EKI serial device server presents a modem interface to theattached serial device: it accepts AT-style modem commands to connect / disconnectto other networking device. If you want serial device running application program toconnect/disconnect to different devices by request, you can use controlling mode. The controlling mode provides three modem AT-style commands.

EKI-1351/EKI-1352/EKI-1521/1522/1524 User Manual 242.3.3 Wireless ConnectionEKI-1351 and EKI-1352 operate in the 802.11b/g WLAN environment, which is cre-ated by an access point working with 802.11b/g protocols. Locate your access pointand connect to the Ethernet network first. Then build up the connection between theaccess point and the EKI-1351 and EKI-1352. While the host PC can not connect toEKI-1351 and EKI-1352, you might switch the EKI-1351 and EKI-1352 as Diag mode.2.3.3.1 Diag ModeSet the switch of EKI-1351 and EKI-1352 to Normal Mode, then power on.Wait for 10 to 20 seconds until the signal quality is stable.Adjust the switch to Diag Mode, then wait for 5 seconds until the signal link is blinking.Return the switch to Normal Mode , then EKI-1351 and EKI-1352 will reboot automatically with Diag Infrastructure Mode. Now EKI-1351 and EKI-1352 will automatically search the field site for access points and create a connection to the one with best signal quality.Start the Configuration Utility tool on your host (ensure your host PC and the possible access points that EKI-1351 and EKI-1352 can connect to, are in the same network). Find the EKI-1351 and EKI-1352 on the network.Reset the network setting as required. (About Network settings, please refer to section 3.2.3 of the manual)After the connection is ready, you can follow the steps shown in chapter 3 to config-ure and set virtual port mapping through network and access point.You can check the signal access quality with the wireless signal strength LED indica-tor. Adjust the antenna of the ADAM module to optimize communication quality.2.3.4 Power ConnectionThe EKI serial device server supports dual +12 ~ 48 VDC power inputs and power-fail relay output.You can connect an alarm indicator, buzzer or other signaling equipment through therelay output. The relay opens if power input 1 or 2 fails ( “Open” means if you connectrelay output with an LED, the light would be off).
