•Windows Utilities: NPort Administrator; Device Search Utility and Windows Driver Manager
•Web Console
•Quick Setup Wizard*
•Serial Console**
•Telnet Console
* Does not support 5100/5200/IA5000 series
** Only available for NPort Series that has RS-232 interface.
Installing Your NPort Device Server
This section describes how to connect an NPort device server to your serial devices for the first time. We
cover Wiring Requirements, Connecting the Power, Grounding the NPort Device Server, Connecting to the
Network, Connecting to a Serial Device, and LED Indicators.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort Device Server.
Wiring Caution!
Calculate the maximum possible current allowed in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowed for each wire size. If the current goes above the
allowed maximum, the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Please be cautious when handling the NPort device server. When plugged in, the NPort’s internal
components generate heat, and consequently the casing may feel hot to the touch. When installed with
other components, make sure that there is at least a 2-cm clearance on all sides of the NPort device server
in order to allow proper heat dissipation.
You should observe the following:
•Use separate paths to route wiring for power and devices. If the power wiring and device wiring paths
must cross, make sure the wires are perpendicular at the intersection point.
NOTE
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.

NPort 5000 Series User Manual
8
•You can use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wires that shares similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separate.
•Where necessary, it is strongly advised that you label wires to all devices in the system.
Connecting the Power
Connect the power line with the NPort’s power input. If the power is properly supplied, the “Ready” LED will
show a solid red color until the system is ready, at which time the “Ready” LED will change to a green color.
Grounding the NPort Device Server
Note: This section only applies if your NPort’s power input is on a terminal block.
Grounding and wire routing help limit the effects of noise caused by electromagnetic interference (EMI). Run
the ground connection from the ground screw to the grounding surface before connecting the devices.
WARNING
NPorts with a power terminal block are intended to be mounted to a well-grounded mounting surface such
as a metal panel.
Type of Power Terminal Block
Shielded Ground (SG)
Applicable Products
The Shielded Ground (sometimes called
Protected Ground) contact is the left most
contact of the 7-pin power terminal block
connector when viewed from the angle
shown here. Connect the SG wire to an
appropriate grounded metal surface.
NPort IA5000 Series
The Shielded Ground (sometimes called
Protected Ground) contact is the left most
contact of the 8-contact power terminal
block
connector when viewed from the angle
shown here. Connect the SG wire to an
appropriate grounded metal surface.
NPort IA5000A Series
The Shielded Ground (sometimes called
Protected Ground) contact is the left most
contact of the 3-pin power terminal block
connector when viewed from the angle
shown here. Connect the SG wire to an
appropriate grounded metal surface.
NPort 5200/5400 Series
NPort 5200A Series
The Shielded Ground (sometimes called
Protected Ground) contact is the second
contact from the right of the 5-pin power
terminal block connector located on the rear
panel of NPort 5600 VDC models. Connect
the SG wire to the earth ground.
NPort 5600 Series

NPort 5000 Series User Manual

Connecting to the Network
Connect one end of the Ethernet cable to the NPort’s 10/100M Ethernet port and the other end of the cable
to the Ethernet network. The NPort device server will indicate a valid connection to the Ethernet in the
following ways:
•The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.
•The Ethernet LED will flash when Ethernet packets are being transmitted or received.
ATTENTION
NPort IA5000/IA5000A/5600-8-DT series NPorts have two Ethernet ports that can be used to create an
open chain of NPort IA5000/IA5000A/5600-8-DT device servers. Be careful not to connect the Ethernet
ports of the two device servers at the ends of the chain.
In other words, NPort IA5000/IA5000A/5600-8-DT series NPorts do NOT support closed chains.
Connecting to a Serial Device
Connect a serial data cable between the NPort and the serial device. Serial data cables must be purchased
separately. They are not provided with the NPort.

RS-485 Port’s Adjustable Pull High/Low Resistor
For some applications, you may need to use termination resistors to prevent the reflection of serial signals.
When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Refer to Appendix B for detailed instructions on how to set the pull
high/low resistor values for different models.
Configuration by Windows Utility
ATTENTION
Before installing and the configuring the NPort Administration suite, make sure your user privilege is set as
system administrator.
NPort Administration Suite is an integrated software suite that bundles NPort Administrator and the IP Serial
Library, providing everything you need to manage, monitor, and modify your NPort from a remote location.
With NPort Administrator, you can easily install and configure your NPort device server over the network.
Five different sets of functions are provided to ease the installation process: Configuration, Monitor, Porting
Monitor, COM Mapping, and IP Address Report.
In this section, we will cover only the “configuration of general settings” using NPort Administrator. For
more detailed information on how to use this suite of useful utilities, refer to Chapter 6.

NPort 5000 Series User Manual
12
You may also use the web console, serial console, or Telnet to configure the device server. Refer to the
section Configuration by Web Console, Configuration by Serial Console, and Configuration by
Telnet Console for additional information on using these consoles.
Installing NPort Administrator
Download and run the setup program from Moxa’s support website (https://www.moxa.com/support/). You
may find it in the Resource section under your product page. Run NPort Administrator when the installation
has been completed.
Searching for Device Servers over a LAN
The Broadcast Search function is used to locate all NPort 5400 device servers that are connected to the
same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP
address, all NPorts connected to the LAN will be located, regardless of whether or not they are part of the
same subnet as the host.
In NPort Administrator, click Search to search your LAN for NPort device servers. When your unit appears
in the search results, you may click Stop to end the search. You may also wait a few more moments for the
search to complete.

NPort 5000 Series User Manual
13
The Configuration screen will list the NPort device servers that were found on the LAN. If your unit cannot
be found, you may have a network problem. Check all cables and verify that your PC and device server are
on the same LAN. If you still have problems, try connecting the device server directly to your PC.
Before configuring the NPort, you will need to unlock the NPort first. Right-click the unit in the Configuration
screen and select Unlock in the pop-up menu. Before configuring the NPort, you will need to unlock it first.
Right-click the unit in the Configuration screen and select Unlock in the pop-up menu.
The default login is:
Username: admin
Password: moxa
For the NPort 5100, 5200, and IA5000 Series, only the password is required to log in.
Adjusting General Settings
Right-click your unit in the Configuration screen and select Configure in the pop-up menu. If your device
server is password protected (the default username is account and the default password is moxa), first
select Unlock in the pop-up menu, and then click the Network tab in the configuration window. Select the
Modify checkbox for items you would like to modify. The device server must be assigned a unique IP
address that is valid for your network. Both fixed and dynamic IP addresses are supported. Consult with
your network administrator if you are not sure how to set these parameters.
Also, For the NPort 5100, 5200, and IA5000 Series, only the password is required to log in.
When you are ready to restart the device server with the new settings, click OK.
Static IP Addresses
For most applications, you will assign a fixed IP address to the device server. To assign a static (fixed) IP
address, the IP Configuration parameter must be set to Static, which is the default setting. You may then
modify the IP Address and Netmask parameters.
Dynamic IP Addresses
For certain network environments, your device server’s IP address will be assigned by a DHCP or BOOTP
server. In this case, instead of assigning the device server’s IP address, you will need to configure the
device server to receive its IP address from the appropriate server. Set the IP Configuration parameter to
DHCP, BOOTP, or DHCP/BOOTP, depending on your network environment. The IP Address and
Netmask parameters will be unavailable for editing since these parameters will be assigned automatically.
If you are not sure whether you need to configure your device server for a dynamic or static IP address,
consult the administrator who set up the LAN.

Verifying Network Settings
If your device server has been configured correctly, you should be able to ping its IP address from your PC.
First, make sure that your PC and device server are on the same subnet, and then ping the device server’s
address. If no response is received, check your cables and network settings.
Configuring Device Port Operation Mode
This section covers configuration of a device port’s operation mode. The operation mode determines how
the device port will interact with the network. Which operation mode you select will depend on your specific
application. Refer to the chart at the end of this section for guidance on selecting the most appropriate
operation mode. For additional information on each operation mode, refer to Chapter 4 and Chapter 5.
Adjusting Operation Mode Settings
The operation mode parameters for each device port can be configured through NPort Administrator. Open
your device server’s configuration window using the same method you used to adjust the network
parameters. On the Operating Mode screen, select the Modify check box and then select the device port
that you wish to configure. Click Settings to configure the selected device port.

Mapping COM Port to Device (only required when operation
mode is set to Real COM or RFC2217)
This section covers how to map the COM ports on a Windows PC to NPort device ports. The mapping will
allow Windows software to access serial devices over the network as if they were local COM devices,
providing instant device networking without software migration. COM mapping is supported in Real COM and
RFC2217 modes only.
The following instructions are for device ports operating in Real COM mode. For device ports operating in
RFC2217 mode, follow the instructions for your particular driver. Real COM mode also supports TTY port
mapping on Linux and UNIX systems.

Advanced Settings
(See Chapter 6 for detailed information about NPort Administrator’s Advanced Settings.)
Tx Mode: In Hi-Performance mode, the driver immediately issues a “Tx Empty” response to the program
after sending data to the NPort. In Classical mode, the driver sends the “Tx Empty” response after
confirmation is received from the NPort. Classical mode is recommended if you want to ensure that all data
is sent out before further processing.
FIFO: Tells the driver whether or not to use FIFO transmission.
Network Timeout: Specifies when an open, close, or serial parameter change operation will time out.
Fast Flush: When enabled, the driver flushes only the local buffer on the host for a Win32 PurgeComm()
function call. When disabled, both the local and remote buffers are flushed. If your application uses
PurgeComm() and it performance seems sluggish, try enabling Fast Flush.
Always Accept Open Requests: Even if the driver cannot establish a connection with the NPort, the user's
software will still be able to open the mapped COM port, the same as with an onboard COM port.
Ignore TX Purge: The application can use Win32 API PurgeComm to clear the output buffer and terminate
outstanding overlapped write operations. Select Ignore TX Purge if you do not want the output buffer to
be purged.
Apply Change
Right-click COM Mapping in the Function panel. Select Apply Change in the pop-up menu to save the
current COM mapping settings. Your application will now be able to access the target serial device using the
COM port.
