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. Obs
erve all electrical
codes dictating the maximum current allow
ed 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.
•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
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. B
e 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.

Configuration by Windows Utility
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 5.
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
Locate and run the setup program on the NPort Document & Software CD. Look for a file named
Npadm_Setup_[Version]_Build_[DateTime].exe (e.g., “Npadm_Setup_Ver1.8_ Build_07041316.exe”). You
may also download the latest version of NPort Administrator from Moxa’s website at:
http://www.moxa.com/support/download.aspx?d_id=1317
Run NPort Administrator when the installation is complete.
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.
www.ipc2u.ru
www.moxa.pro

NPort 5000 Series Getting Started
2-8
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.
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.
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 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.
When you are ready to restart the device server with the new settings, click OK.

2-9
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 3and Chapter 4.
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.

The following parameters need to be set correctly on the device port to ensure proper communication with your
device. Refer to your device’s documentation for the appropriate settings.
Parameter Setting Factory Default Description Necessity
Baudrate 110 bps to
230400 bps
115200 bps The data transmission rate to and from the
attached serial device.
Required
Data bits 5, 6, 7, 8 8 The size of each data character. Required
Stop bits 1, 1.5, 2 1 The size of the stop character. Required
Parity None, Even,
Odd, Space,
Mark
None The parity that will be used. Even and Odd
parity provide rudimentary error-checking;
Space and Mark parity are rarely used.
Required
Flow control None, RTS/CTS,
DTR/DSR,
Xon/Xoff
RTS/CTS The method used to suspend and resume
data
transmission to ensure that data is not
lost. RTS/CTS (hardware) flow control is
recommended.
Required
FIFO Enable, Disable Enable Controls whether the device port’s built-in
128-byte FIFO buffer is used. When
enabled, the FIFO helps reduce data loss
regardless of direction.
Required
Interface* RS-232
RS-422
2-wire RS-485
4-wire RS-485
RS-232 The serial interface that will be used. The
options that are available depend on the
specific model of device server.
Required
*Supported interfaces vary by model; refer to your NPort’s datasheet for a list of supported serial interfaces.

The serial communication 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 configure network
parameters. On the Serial 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.
Modify the parameters as needed. When you are ready to restart the device server with the new settings, click
OK.
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.
Specifying the Target Device Server
In NPort Administrator, click COM Mapping in the Function panel to open the COM Mapping window.
Right-click on an empty line in the COM Mapping window. Select Add Target in the pop-up menu to assign your
device server as the mapping target.

Assigning COM Port Number to Device Port
The COM Mapping screen shows a list of available device ports on the network. Right-click the target device
port and select COM Settings in the pop-up menu.
On the Basic Settings screen, select the COM port number that will be mapped to the device port. You can
map multiple COM ports at the same time by selecting the Auto Enumerating check box to number the COM
ports automatically.

On the Serial Parameters screen, adjust the settings to match your device. These settings, which are only
used for serial printers, must also match the settings on the device port. Click OK when you are satisfied with
your changes.
Advanced Settings
(See Chapter 5for 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.
