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.
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.
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.
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.
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 this section, we will give you an overview of EKI-1521/1522/1524 hardware and installation. 2.2.1 LED Indicators There are LEDs display the power status, network status, and serial communication status located on the front panel of EKI-1521, EKI-1522, and EKI-1524, each of them has its own specific meaning as below table.

EKI-1521/1522/1524 provides Multi-access function through one Ethernet connection path or dual Ethernet connection paths. Allow the maximum of five connections to open one serial port simultaneously. In the mode, all connections have 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 kinds of Multi-access function. One is Normal mode; another is RoundRobin mode.
3.4.3 Setting TCP/UDP Server/Client Operating Mode Parameters EKI-1521/1522/1524 provides various operating modes. Selecting the "USDG Mode" as the following figure to change the mode of the port to TCP server/client or UDP mode. Before setting the TCP server mode, you have to check the serial port setting in advance. Mode: There are two kinds of operation modes: Data Mode and Control Mode. To use TCP server operating mode correctly, you have to select Data Mode.
Protocol: TCP and UDP. Enable Time sharing: This function is the same with the Multi-Access function. Please refer to the virtual COM operating mode setting. Peers to Receiving Data: 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.
3.4.4 Setting Control Operating Mode Parameters The “Control mode” is a very special operating mode. The EKI-1521/1522/1524 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.
Table 3.1: AT Commands List Function ATDT “Forms a TCP connection to the specified host. Ex: ATDT 192.0.55.22:5201 In above example, the EKI serial device server forms a raw TCP connection to the networking device (192.0.55.22). The TCP port is 5201.” ATA Answering an incoming call +++ Returns the user to the command prompt when entered from the serial port during a remote host connection.
Allow any IP to access. If this function is enabled, any PC can access data from this serial device server. Specified IP which can access If you want to restrict access to certain PCs, you can list their IP addresses in this area. The limit is 32 PCs. 3.5.2 Port Monitor Advantech Serial Device Server Configuration Utility provides an excellent function to monitor the serial port status. User can check the status of the serial ports.

Chapter 4 Setting COM Redirector 4
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.
Chapter 4 43 EKI-1521/1522/1524 User Manual Setting COM Redirector The COM ports in the “Virtual Com Ports” listing are now available for use by Windows applications.
4.1.2 Manual Mapping Right click the serial device name on the sub-tree of Device Server List area and select the “Manual Mapping” function. ADAM series, EDG series, and EKI wireless series have only one IP address. Select the serial port on the device server and the host COM that you want to set. Press
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.
4.1.3 Manual Direct Mapping Virtual COM Port Click the button on the Quick Took area, 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. Individually Remove Right click on COM port you have mapped and select “Remove This Port”.
Chapter 4 The purpose of this test is to make sure the communication from host PC to EKI1521/1522/1524 is OK. If there is still an error, you can check the communication from the EKI-1521/1522/1524 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.
2. Select which COM port you want to run a 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.
