4.3.2 USDG Data TCP Server mode
In TCP server mode, the TCP connection is initiated from the host to the EKI-1511L
device server. This operation mode supports a maximum of five simultaneous
connections for each serial port on an EKI-1511L device server from a single or
multiple hosts. However a multi-host connection simultaneously transmits the data
from a single serial port.

4.3.3 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-1511L USDG UDP Port (Default Port 5300). In the default UDP client mode,
EKI-1511L 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.
4.3.3.1 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-1511L does not receive data during established idle time, the
EKI-1511L will disconnect temporarily. When the data comes in, it will reconnect
automatically. Users do not need to reconnect.
