AWK-1121/1127 Web Console Configuration
3-28
TCP Server Mode
In TCP Server mode, the AWK
-1127
serial port is
assigned an IP:port
address that is unique on
your TCP/IP network. It waits for the host
computer to establish a connection to the
attached serial device. This operation mode also
supports up to four simultaneous connections, so
multiple hosts can collect data from the attached
device at the same time.
Data transmission proceeds as follows:
1. A host requests a connection to the
AWK-1127 serial port.
2.
Once the connection is established, data
can be transmitted in both
directions—
from the host to the device,
and from the device to the host.
When Mode is set to TCP Server on a serial port’s Operation Modes page, you will be able to configure
additional settings such as TCP alive check time, Inactivity time, and Max connection.
TCP Alive Check Time
Setting Description Factory Default
0 to 99 min. This field specifies how long the AWK-1127 will wait for a
response to “keep alive” packets before closing the TCP
connection. The AWK-1127 checks connection status by
sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no
response to the “keep alive” packets.
1 to 99: If the remote host does not respond to the packet
within the specified time, the AWK will force the existing TCP
connection to close.
7 min.
