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 simply want a serial device to communicate directly to another
serial device over the network. You can use a pair of NPort 5600-8-DT device servers to
accomplish this, with Pair Connection Master and Slave modes. Simply set one device port to Pair
Connection Master mode and the other device port to Pair Connection Slave mode. It does not
matter which device port is master and which is slave.
For the device port in Pair Connection Slave mode, designate a Local TCP port to be used for
communication. For the device port in 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 device servers can be connected by
an Ethernet cable, or they can be connected to the same network.

Description: This is the time limit for keeping the connection
open if a host does not respond to “TCP alive check”
packets. If the host does not respond within the specified
time, the connection will be closed. A setting of 0 means
that the connection will remain open even if the host never
responds.
