TCP Server
Setting Value Notes Necessity
TCP port valid port number
The TCP port that other devices
must use to contact this device. To
avoid conflicts with standard TCP
ports, the default is set to 4001.
Required
valid IP
Allows contact with only the
specified remote IP address.
Destination IP
addr
blank
Allows contact with any remote
networked device.
Optional
Delimiter 1
(Hex)
ASCII code for
the 1
st
delimiter
Optional
Delimiter 2
(Hex)
ASCII code for
the 2
nd
delimiter
Once the NPort receives both
delimiters through its serial port,
it immediately packs all data
currently in its buffer and sends
it out the NPort’s Ethernet port.
Note: Delimiter 2 is optional. If
left blank, then Delimiter 1 alone
trips clearing of the buffer.*
Optional
blank (or 0)
Disabled.
Force transmit
(ms)
1 – 65535
Forces the NPort’s TCP/IP
protocol software to try to pack
serial data received during the
specified time into the same data
frame. *
Optional
blank (or 0)
Disabled.
Inactivity time
1 – 65535 ms
TCP connection is automatically
closed by this device if the serial
port is idle for the given time.
Optional
0
TCP connection is never closed
by this device.
TCP alive check
time
1 – 99 min.
TCP connection is automatically
closed by this device if there is no
TCP activity for the given time.
Optional
*
If the size of the serial data received is greater than 1K, the NPort will
automatically pack the data and send it to the Ethernet.
TCP Client
The TCP Client operation mode is designed for use with serial devices that act as
clients. That is, they actively request that a TCP connection be established with
another device. Once the connection is established, data transmission can
proceed in both directions.
