2.1 Understanding Serial Device Servers The EKI serial device servers are network-based, serial device servers for connecting 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 network device. It extends traditional COM ports of a PC with access over a TCP/IP network.
Chapter 2 EKI-1351 and EKI-1352 has an 802.11b/g transceiver in addition to its serial and Ethernet ports. Each serial port is connected to the serial communication port of a device. The wireless transceiver connects to another wireless device or to an Access Point (AP). Getting Started 2.1.
2.1.2.1 Normal Mode The Advantech redirector connects the Advantech serial device server while an application open the COM port and disconnects from the Advantech serial device server 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. 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 via a cable.
Chapter 2 Getting Started 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 Server Mode In TCP server mode, you might initiate the TCP connection from host to EKI serial device server. This operation mode support max.
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 maximum 16 (EKI-1521, EKI-1522, and EKI1524) or maximum 4(EKI-1351 and EKI-1352) simultaneous connections for each serial port on EKI serial device sever 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 connect to using Advantech serial device server utility.
Two native serial devices can communicate over a Ethernet network without any intermediate host PC and software programming. Serial Tunneling is very simple to use. You can use Advantech serial device server utility to designate one serial port as the tunneling master and another serial device server port as the tunneling slave. Chapter 2 2.1.5 Serial Tunneling mode Getting Started 2.1.6 UDP Server/Client Mode UDP is used primarily for broadcasting messages over a network.
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 modem AT-style commands.

2.3 Connecting Hardward Next, we will explain how to find a proper location for your EKI serial device server, and then explain how to connect to the network, hook up the power cable, and connect to the EKI device server serial port. 2.3.1 Choosing a Location Due to its versatility and innovative design, EKI serial device server can be : Fixed to a panel mount Fixed to a DIN-rail. 2.3.1.1 Panel/Wallmounting The EKI serial device servers can be attached to a wall using the included metal brackets.
Chapter 2 2.3.1.2 DIN-rail Mounting You can mount the EKI serial device server on a standard DIN rail. The DIN-rail kit is screwed on the industrial switch when out of factory. If the DIN-rail kit is not screwed on the industrial switch, please screw the DIN-rail kit on the switch first. First, hang the EKI serial device sever to the DIN-rail with angle of inclination. See below figure. Getting Started Figure 2.14 DIN-rail Step 1 Then, let the device down straight to slide over the rail smoothly.
2.3.3 Wireless Connection EKI-1351 and EKI-1352 operate in the 802.11b/g WLAN environment, which is created by an access point working with 802.11b/g protocols. Locate your access point and connect to the Ethernet network first. Then build up the connection between the access point and the EKI-1351 and EKI-1352. While the host PC can not connect to EKI-1351 and EKI-1352, you might switch the EKI-1351 and EKI-1352 as Diag mode. 2.3.3.
