By disabling the Frame Break function, the series devices will wait for a "Response
Timeout" period, whether or not the device has transmitted data. During this period,
the host commands are queued and processed in the order received.
If Frame Break is enabled, the serial port idle is longer than the Frame Break period.
The EKI-1500 Series assumes the communication is completed and continues with
the next query. This is an efficient way to reduce waiting time and improve
performance.

USDG Data Mode
The EKI-1526NL-CS | 1528NL-CS Series can function either as Data server or Data
client. Both operations support TCP and UDP protocols. The Series allows you to
treat your serial devices as if they were networking devices. You can issue
commands or transmit data from serial devices, connected to a EKI-1526NL-CS |
1528NL-CS Series device, to any devices that are connected to the Internet.

USDG TCP Client Mode
In TCP Client mode, the TCP connection is established from the EKI console server.
This operation mode supports a maximum of 16 simultaneous connections for each
serial port on EKI-15xx series to one host or several hosts. You can configure the IP
address and TCP port number of the network hosts connected to the EKI console
server using the Advantech Console Server Configuration Utility. After configuring the
devices, when the EKI console server receives the data from the serial port, and the
device server connects to the hosts which are configured.
In USDG Data TCP Client mode, you may need to enable the peer numbers you
would like to receive. You can set a maximum 16 network devices to which you may
connect. You need to fill out the IP Address and Port (including local port and peer
port) of each network device to which you want to connect.
