Chapter 1 Introduction

Moxa’s NPort W2004 Series of wireless serial device servers give you an easy way to connect
your RS-232/422/485 serial devices to a WLAN. The 4-port NPort W2004 is ideal for
environments where a LAN is not available, or where serial devices are moved frequently.

NPort W2004 User’s Manual Introduction

Overview

Moxa’s NPort W2004 wireless device server is the ideal choice for connecting your
RS-232/422/485 serial devices—such as PLCs, meters, and sensors—to a Wired Ethernet LAN
and Wireless LAN. Your communications software will be able to access the serial devices from
anywhere over a local LAN, WLAN, or the Internet. Moreover, the WLAN environment offers an
excellent solution for applications in which the serial devices are moved frequently from place to
place.

NPort W2004 wireless serial device servers support automatic IP configuration protocols (DHCP)
and manual configuration via a handy web browser console. Both IP configuration methods ensure
quick and effective installation, and the NPort Windows Driver Manager Utility makes Port
Mapping very convenient to configure.

An external antenna increases the range of the wireless connection. Users can position the
adjustable antenna for maximum signal strength or even replace the antenna with their own for
additional flexibility and scalability. This feature is particularly useful when a serial device is
connected in a high interference area. As an added feature, a signal strength indicator is located on
the front panel to make it easier to troubleshoot connection problems.

NPort W2004 wireless serial device servers ensure the compatibility of network software that uses
a standard network API by providing TCP Server Mode, TCP Client Mode, and UDP Mode. The
Real COM/TTY drivers allow software that works with COM/TTY ports to be set up to work over
a TCP/IP network in no time. This excellent feature preserves your software investment and lets
you enjoy the benefits of networking your serial devices instantly.

To make your management task easier, the NPort W2004 Series provides additional features, such
as password authentication, IP filter, WEP support for 64-bit and 128-bit encryption, and SNMP
support.

NPort W2004 User’s Manual Getting Started

Wiring Requirements

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your device.

Wiring Caution!

Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes 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!

Be careful when handling the device. When plugged in, the device’s internal components
generate heat, and consequently the casing may feel hot to the touch.

You should also pay attention to the following items:

! 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.

! 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 shares similar electrical characteristics can be
bundled together.

! Keep input wiring and output wiring separate.
! Where necessary, it is advisable to label the wiring to all devices in the system.

Connecting the Power

Connect the 12-48 VDC power line with NPort W2004’s power jack. When the power is supplied
properly, 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.

Connecting to the Network

Connect one end of the Ethernet cable to NPort W2004’s 10/100M Ethernet port and the other end
of the cable to the Ethernet network. If the cable is properly connected, NPort W2004 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.

NPort W2004 User’s Manual Getting Started

Connecting to a Serial Device

Connect the serial data cable between NPort W2004 and the serial device. Serial data cables are
optional accessories for NPort W2004. Refer to Chapter 1 under Optional Accessories in the
Ordering Information section for information about the RJ45-to-DB25 and RJ45-to-DB9 cables.

LED Indicators

LED Indicators—The front panel of NPort W2004 has eleven LED indicators, as described in the
following table.

in increments of 20%. The bottom LED of these 5 will be lit
when the WLAN links to the access point.

Chapter 3 Initial IP Address Configuration

When setting up your NPort W2004 for the first time, the first thing you should do is configure the
IP address. Select one of the initial IP Address configuration methods to configure NPort W2004’s
IP Address. For more details about network settings, see the Network Settings section from
Chapter 5, Web Console Configuration.

This chapter covers the following topics:

! Serial Console (19200, n, 8, 1)

NPort W2004 User’s Manual Initial IP Configuration

Installation Procedure for First-time Users

STEP 1: After removing NPort W2004 from the box, use a cross-over Ethernet cable to connect

directly to your computer’s Ethernet port.

STEP 2: Attach the power adaptor to the NPort W2004 and then plug the adaptor into an

electrical outlet.

STEP 3: Use the Web console to configure the NPort W2004 via the Ethernet port.

NOTE

We recommend that you use the web console to configure NPort W2004. See Chapter 5 for
instructions on how to use the web console.

Factory Default IP Address

NPort W2004 is configured with the following default IP addresses:

LAN:

Setting static IP
IP Address 192.168.126.254
Netmask 255.255.255.0

# If the Ethernet port is unable to get an IP address from the DHCP server, then the IP
address/netmask will revert to 192.168.126.254/255.255.255.0.

WLAN:

Setting static IP
IP Address 192.168.127.254
Netmask 255.255.255.0

# If the WLAN port is unable to get an IP address from the DHCP server, then the IP
address/netmask will revert to 192.168.127.254/255.255.255.0

NOTE

If you forget the IP address, you can use the NPort Search utility (from your PC) to locate the
NPort W2004 unit over the network. You will be able to view the IP address on the screen.

NOTE

NOTE

Only one Network Interface can be used at the same time. If the Ethernet Link is active, then the
WLAN will be disabled. If the WLAN is active, then the Ethernet Link will be disabled.

The default login parameters are: username = admin, and password = blank.
