When to Make Adjustments
The default settings for each operation mode are designed to work for most applications and usually do not
need to be modified. However, adjustments may be required for the following situations:
•
You need to control network data packing using specific delimiter characters.
Adjust
Delimiters 1 and 2 and Delimiter process.
•
Multiple hosts will simultaneously access the attached device.
Adjust
Max Connection, Ignore Jammed IP, and Allow driver control.
•
Data will be broadcast from the serial device to multiple network destinations.
Adjust
Destination IP 1 through 4.
•
You are using Pair Connection modes to connect two serial devices over Ethernet.
Adjust
Local TCP port and Destination IP Address
Using Pair Connection Modes
For some applications, you may want to configure two serial devices to communicate directly with each
other over the network. This can be done with a pair of NPort device servers configured for Pair Connection
Master/Slave modes. Configure one device port on one of the NPorts to Pair Connection Master mode, and
one device port on the other NPort to Pair Connection Slave mode. It doesn’t matter which NPort is the
master and which NPort is the slave.
For the device port configured for Pair Connection Slave mode, designate a Local TCP port to be used for
communication. For the device port configured for Pair Connection Master mode, enter the slave’s IP
address and Local TCP port as the
Destination IP
.
Once both device ports have been configured, the attached serial devices will communicate over Ethernet as
if they were connected by a serial cable. The two NPorts can be connected by an Ethernet cable, or they can
be connected to the same network.

Setting Options: 0 to 99 minutes
Default: 7 minutes
Description: Specifies the time counter to check if the TCP
connection is alive. If there is no response from the other end of the
connection after the specified time, then the TCP connection will be
closed. A setting of 0 means disabled. This is a good practice to free
up the device’s resources.
