53 EKI-1321/1322 User Manual
Chapter 5 Web Configuration
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 con-
versation. Each node on a TCP/IP network has an IP address, and each IP address
allows connections 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.
Each port has its own data listen port to accept connected request of other network
device. So, the data listen port can't be set the same value. You can transmit/receive
data to/from device via the data listen port.
Command Listen Port: Each port has its own command listen port to accept
connected requests of other network devices, thus the command listen port can't be
set the same value. You can use 'AT command' to change the port set- ting via the
command listen port. The Command Listen Port must be different from the Data Lis-
ten port.
Response Timeout: Please refer to the description in chapter 4.8.2
Frame Break: Please refer to the description in chapter 4.8.2
Auto connect Peer IP: EKI-1321/1322 will connect to TCP/IP which are set at Peers
page automatically after boot up.
Pack Condition: There are 3 types of pack condition by length, time or specific char-
acter. “By size”: the system will collect the data with fixed size and send out accord-
ing 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.
Port Data Buffering: EKI-132x series provide the function of data buffering to avoid
the data lost.
Media: There are three types. None is no data buffering. RAM is to buffer the data in
RAM storage. SD Card is to buffer the data in SD card if you plug-in the SD card in
EKI-132x series devices.
When Data Full: When buffering space is full, you can select to “STOP” or “OVER-
WRITE” the buffering data.
MAX Buffering Size: The storage size will be used for data buffering.
Peers for Receiving Data (max. 16 sets): You can set maximum 16 Ethernet
devices which you want to connect. You need to fill out the IP address and Port num-
ber of Ethernet devices you want to connect. You also need to fill out the local port,
you can choose your prefer local TCP port or key in zere "0" to let EKI-1321/1322
decide itself.
