37 EKI-1526(TI) | 1528(TI) User Manual
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-1528 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-1526(TI) | 1528(TI) 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 trans-
mit data from serial devices, connected to a EKI-1526(TI) | 1528(TI) 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 serial device
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 serial
device server using the Advantech Serial Device Server Configuration Utility. After
configuring the devices, when the EKI serial 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.
