4.6.3.3 USDG UDP Server/Client Mode
The USDG UDP mode is primarily used for the broadcasting of messages over a
network. In UDP server mode, data is transmitted from the Host connected to the
EKI-1361 & EKI-1362 Series USDG UDP Port (Default Port 5300). In the default
UDP client mode, EKI-1361 & EKI-1362 Series device servers simultaneously
transmits UDP messages to a maximum of 16 peers.
USDG Data mode supports Data Idle Timeout, Data Listen Port, and Command
Listen Port parameters.
4.6.3.3.1 Data Idle Timeout
The default is 60 seconds. If you want to keep connection continually, you can
disable the Data Idle Timeout. Data idle Time is the time period for which the device
waits for data. If the EKI-1361 & EKI-1362 Series does not receive data during
established idle time, the EKI-1361 & EKI-1362 Series will disconnect temporarily.
When the data comes in, it will reconnect automatically. Users do not need to
reconnect.
4.6.3.3.2 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-1361 & EKI-1362 Series Port1 is 5300. 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.
4.6.3.3.3 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>.
