EKI-1500 Series User Manual
4.3.3.2
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. The port range is 1024-
65533. If an unknown caller wants to connect to the system and request services,
they must 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 can allow
connection on one or more TCP port. The well-known TCP ports are those that have
been defined; for example, port 23 is used for Telnet connections. There are also
custom sockets that users and developers define for their specific needs. The default
TCP/UDP port of the EKI-1500 Series Port1 is 5300, Port2 is 5301, etc. Users can
adjust them according to preference or application. Each port has its own data listen
port to accept the connection requests of other network device. The data listen port
cannot be set to the same value. You can transmit/receive data to/from devices via
the data listen port.
4.3.3.3
Command Listen Port
Each port has its own command listen port to accept connection requests from other
network devices, so the command listen port cannot be set to the same value. The
Command Listen Port is different from the Data Listen port. <Default Port is 5400>

USDG 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 a serial device running application program to connect/disconnect to dif-
ferent devices on request, this function is available through the USDG Control mode.

4.4.1
Hangup Character
The default character is “+”. After you have connected to another serial device an via
EKI device, you may need to disconnect, using the command “+++”. To do this, press
“+” three times and wait for the Guard timeout <default value is 1000ms>; the device
will disconnect. You can set “Guard Time” to define the idle time.
