Advantech EKI-1352, EKI-1351 manual Serial Tunneling Mode, UDP Server/Client Mode, Control Mode

2.1.5Serial 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.

2.1.6UDP Server/Client Mode

UDP is used primarily for broadcasting messages over a network. In the UDP server mode, EKI-1351/1352 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.

2.1.7Control 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 kinds of modem AT-style commands. The serial devices can use these commands to control EKI-1351/1352 connecting or discon- necting to remote networking devices. Thus intelligent serial devices such as stand- alone PLC will send /receive data to/from devices one by one via Ethernet.
