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 in each power
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings,
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 2 cm clearance on all sides of the NPort device server in order to allow proper
heat dissipation.

WARNING

a metal panel.

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

You should observe the following:

• Use separate paths to route wiring for power and devices. If 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 wiring that sh a res similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separate.

• Where necessary, it is strong ly advised that you label wiring to all devices in the system.

wire and common wire. Observe all electrical codes

Connecting the Power

Connect the power line with the NPort’s power inp u t. If the power is properly supplied, the “Ready” LED will
show a solid red color until the system is ready, at which time the “Read y” 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 prior to connecting devices.

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 w hen connected to a 100 Mbps Ethernet network.

• The Ethernet LED maintains a solid orange color w hen connected to a 10 Mbps Ethernet network.

• The Ethernet LED will flash when Ethernet packets are being transm itted or received.

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 u sing termination resistors, it is important to set the pull h igh/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

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.

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 n etwork 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 popup menu. If your device server
is password protected, first select Unlock in the popup menu, and then cl ick 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.

NPort 5000 Series Getting Started

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 se t u p 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 ca bles 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 3 and 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 chec k box and then select the device port that you wish to
configure. Click Settings to configure the selected device port.

The serial communication parameters for each device port can be configured through NPort Administrator.
Open your device server’s configuration window using the same met h od 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 se rver 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 an empty line in the COM Mapping window and select Add Target in the pop-up menu to assign
your device server as the mapping target.

your changes.

Advanced Settings

(See Chapter 5 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 E mp ty” 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 performance seems sluggish, try enab ling 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. Selecting Ignore TX Purge if you do not want the output buffer to
be purged.

IP Address Report

When NPort products are used in a dynamic IP environment, users must spend more time with IP management
tasks. For example, if the NPort works as a server (TCP or UDP), then the host, which acts as a client, must
know the IP address of the server. If the DHCP server assigns a new IP address to the NPort, the host must
have some way of determining the NPort’s new IP address.

NPort products help out by reporting their IP address periodically t o the IP location server, in case the dynamic
IP has changed. The parameters shown below are used to configure the Auto IP report function. There are two
ways to develop an “Auto IP report Server” to receive NPort’s Auto IP report.

1. Use D evice Server Administrator’s IP Address Report function.

2. Auto IP report protocol, which can receive the Auto IP report automatically on a regular basis, is also
available to help you develop your own software. Refer to Appendix E for details about the Auto IP report

protocol.
