2.1 Understanding EKI-1351/1352 The EKI-1351/1352 is network-based, serial device server for connecting RS-232/422/485 devices, such as CNCs, PLCs, scales, and scanners, directly to a TCP/IP network. Once connected through EKI-1351/1352, 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 monitor remote serial devices either over a LAN or over the WAN.
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.

Chapter 3 3.3.1 Wireless Basics 3.3.1.1 Wireless Basic Information l Firmware Version: Here is the firmware version of the wireless module embedded in the EKI-1531 and EKI-1352. The wireless module firmware might affect the wireless connection. Write down the version number and provide to our customer service if you have wireless connection problems. MAC Address: The MAC address is for the local system to identify and locate each serial device servers.
3.3.1.3 Wireless Basic Settings l Region: Set the region. Each region has its default channel range. When you choose a specific region, the optional channel range and numbers in the below drop-down menu will be changed automatically. l Mode: There are two kinds of basic service set (BSS) in this drop-down menu. l l 802.11b/g Infrastructure mode : For infrastructure BSS usage, you should set up the SSID of the specific access point (AP). Or just choose .ANY.
Chapter 3 Data Rate: The data transmission rate is determined by the device and access point. If there is a restriction for the device or AP, a fixed data rate has to be chosen. Otherwise, we suggest the “Automatic” choice. l SSID: You can input the AP SSID here. If you doesn’t know which access point is the most appropriate one, just set ”ANY” for an automatic search. 3.3.1.
3.3.2 Wireless Authentication EKI-1351 and EKI-1352 now support WEP (Wired Equivalent Privacy) encryption operation mode. WEP is a kind of standard to encrypt the data frame. We will enhance other encryption mode in future. l Authentication Type: There are three kinds of types in this drop-down menu. l l l Open System: No encryption for network communication. You can neglect the key setting on the right side. WEP Share Key: Both communication devices use the same key as encryption.
Chapter 3 Hexadecimal 64 bits Up to 5 random characters on the keyboard Up to 10 random hexadecimal characters (0 ~ 9, a ~ f) 128bits Up to 13 random characters on the keyboard Up to 26 random hexadecimal characters (0 ~ 9, a ~ f) l Key Index: This lists the supported encryption keys that you can choose from l Key Value: You can set up the key value in this index.
3.3.3 Wireless Advanced The tab identifies several parameters that are related to the 802.11b/g wireless network. We strongly suggested the default settings are not changed unless necessary. If you want to recovery to factory value, you click the “Reset to factory default value”. Parameters Default Value Range Beacon Interval 100 0~65535 RTS Threshold 2347 0~2347 Fragment Threshold 2346 256~2346 Preamble Long Long/Short 3.3.3.
3.3.3.2 RTS Threshold RTS Threshold is the frame size above that an RTS/CTS handshake will be performed before attempting to transmit. RTS/CTS ask for permission to transmit to reduce collisions, but add considerable overhead. Disabling RTS/CTS can reduce overhead and latency in WLANs where all stations are close together, but can increase collisions and degrade performance in WLANs where stations are far apart and unable to sense each other to avoid collisions.
3.4.1 Setting Serial Port Parameters Description: You can give a more detailed description on the function of the port for easier management and maintenance. Descriptions have a limit of 128 characters. Type: The EKI-1351/1352 offers three kinds of serial protocols, RS-232, RS-422 and RS-485. You can use any of these three serial protocols according to your requirements. Baud Rate: The EKI-1351/1352 supports baud rate from 50 to 921.6Kbps. Total throughput up to 1.
Chapter 3 Stop Bits: The EKI-1351/1352 provides three options: 1, 1.5 and 2. Flow Control: The EKI-1351/1352 provides four options: None, XOn/XOff, RTS/ CTS, and DTR/DSR. Note When you have finished the configuration of these settings for each category, please press the “Apply” button in order to make these settings effective on all serial device servers. (Will restart your serial device server immediately) 3.4.
Host Idle Timeout (10~255 seconds): 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 connectived device. Note The default value of "Host Idle Timeout" is 255 seconds. EKI-1351/1352 provides Multi-access function through 802.11b or 802.11g WLAN.
Frame Break is a very import parameter for Round Robin mode. This parameter is a smart way to reduce inefficient waiting time and EKI-1351/1352 can transmit data more efficiently. Disabling the Frame Break function, EKI-1351/1352 will wait for data until "Response Timeout" setting time is reached. During this period, the commands from hosts will be queued and EKI-1351/1352 just processes this command.
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. 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.
Chapter 3 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 4 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.
Please refer to the TCP/UDP server operating 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-1351/1352, 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.
The EKI-1351/1352 serial device server provides the advanced settings for some special applications which need critical time requirements. In normal applications, these settings are recommended not to be set to avoid the unusual action happened. Chapter 3 3.4.5 Advanced Setting Configuration 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.
3.5 Security Configuration 3.5.1 Accessible Function Allow any IP to access. If this function is enabled, any PC can access data from this serial device server.
