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.

2.1.6
UDP Server/Client Mode
UDP is used primarily for broadcasting messages over a network. In the UDP server
mode, EKI series access max. 8 hosts’ UDP message. In the UDP client mode, EKI
serial device servers transmit UDP message to max. 16 hosts simultaneously.
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 kinds of modem AT-style commands. The serial
devices can use these commands to control EKI series connecting or disconnecting
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.
