Advantech EKI-1528-DR - Figure 4.3 USDG TCP Client Mode; USDG Data Mode; USDG TCP Client Mode

EKI-1500 Series User Manual 40
If the Frame Break function is disabled, EKI-1500 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 perfor-
mance.
4.3 USDG Data Mode
The EKI-1500 Series can funciton as either a Data TCP server or a Data TCP client.
Both operations support TCP and UDP protocol. The EKI-1500 Series allows you to
treat your serial devices as if they were networking devices. You can issue com-
mands or transmit data from serial devices, connected to a EKI-1500 Series device,
to any devices that are connected to the Internet.
4.3.1 USDG TCP Client Mode
In TCP Client mode, the TCP connection is established from the EKI-1500 Series
device server. This operation mode supports a maximum of 16 simultaneous connec-
tions for each serial port on EKI-1500 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-1500 Series device server using the Advantech Serial Device Server Configura-
tion Utility. After configuring the devices, when the EKI-1500 Series device server
receives the data from the serial port, and the device server connects to the hosts
which are configured.
Figure 4.3 USDG TCP Client Mode
In USDG Data TCP Client mode, you may need to enable the peer numbers you
would like to receive. You can set a maximum sixteen 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.
