Once connected through EKI-1321/1322, serial device will be able to send and receive data through cellular ISP 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 Figure 2.4 TCP Server Mode 9 EKI-1321/1322 User Manual Getting Started 2.1.3 TCP Server Mode Chapter 2 2.1.2.
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 four simultaneous connections for each serial port on EKI-1321/1322 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.
UDP is used primarily for broadcasting messages over a network. In the UDP server mode, EKI-1321/1322 access max. of 8 hosts’ UDP message. In the UDP client mode, EKI serial device servers transmit UDP message to max. of 4 hosts simultaneously. Chapter 2 2.1.6 UDP Server/Client Mode 2.1.

5.8.2 Setting Virtual COM Operating Mode Parameters The Advantech serial device servers extend 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. Advantech serial device servers come 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.
EKI-1321/1322 provides Multi-access function through cellular WAN. 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. Normal mode: Disabling “Response Timeout” parameter, EKI-1321/1322 will operate in “normal mode”.
Pack Condition: There are 3 types of pack condition by length, time or specific character. “By size”: the system will collect the data with fixed size and send out according to your setting. “By interval”: the system will collect the data in fixed interval and send out. “By end-character”: the system will send out the package when it find the coming of specific character. RVcom Number: 0 means disable RVcom function. There can have maximum of 5 peers.
EKI-1321/1322 User Manual Web Configuration 53 Chapter 5 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 connec- tions. 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. Each node on a TCP/IP network has an IP address, and each IP address allows connections on one or more TCP port.
5.8.4 Setting Control Operating Mode Parameters 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 “+++” 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.
5.8.5 Setting RFC2217 Operating Mode parameters RFC-2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection between a host computer and a serial device by mapping the serial port on the EKI-132x to a local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Listen Port: This is the TCP port number assignment for the serial port on the EKI132x.
Short Message Service (SMS) is a telecommunications protocol that allows sending "short" (160 characters or less) text messages. It is available on most digital mobile phones and some personal digital assistants with built-in wireless capability. GSM technology offers the benefit of using SMS (short message service) as an easy way to communicate over the mobile network. Chapter 5 5.8.
