Introduction
1.1 ND-8511(D) Overview
ADLINK ND-8511(D) is a 1-port RS-232/422/485 to Ethernet data
converter. It is a compact sized communication module that allows users to
control serial devices (RS-232/422/485) over a TCP/IP-based Ethernet
network.
Users may connect host computer systems (Windows98/ME/2000/XP or
Linux OSs) to a native serial port through a TCP/IP Ethernet. With one
asynchronous serial port connection on one end and a 10/100 Mbps
Ethernet connection on the other, ND-8511(D) also allows any device that
primarily supports the asynchronous communications protocol to attach to
a network. ND-8511(D) works like an add-on single-port serial board to PC
servers, but with advantages of the TCP/IP network protocol. With the ND-
8511(D), users are able to control asynchronous serial devices from
virtually any location.
Serial devices connects through a virtual Ethernet link of the, but are
recognized as a real COM port by Windows. ND-8511(D) can be used with
existing applications, and comes with a utility program providing a simple
step-by-step installation procedure and maintenance wizard that gives
users easy access to asynchronous device.

2 •Introduction
1.2 Protocol Support
The ND-8511(D) uses the Internet Protocol (IP) for network communications
and the Transmission Control Protocol (TCP) to assure that no data is lost
or duplicated. Other supported protocols are:
•ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and
SNMP for network communications and management.
•TCP, UDP, and Telnet for connections to the serial port.
•TFTP for firmware and web page updates.
•IP for addressing, routing, and data block handling over the
network.
•User Datagram Protocol (UDP) for typical datagram applications in
which devices interact with other devices without maintaining a
point-to-point connection
•SMTP for e-mail transmission
1.3 Features
The ND-8511(D) connects serial devices to Ethernet networks using the IP
protocol family:
•ATM Machines
•CNC Controllers
•Data Collection Devices
•Universal Power Supply (UPS) Management Units
•Telecommunications Equipment
•Data Display Devices
•Security Alarms and Access Control Devices
•Handheld Instruments
•Modems
•Time/Attendance Clocks and Terminals
The ND-8511(D) connects devices through a TCP data channel or through
a Telnet connection to computers or another Device Server. Datagrams can
be sent by UDP. The ND-8511(D) contains a web [http] server that allows
presentation of custom content and can be easily configured through the
server.

Installation
2.1 Install ND-8511(D) Configuration Utility
2.1.1 Install the Utility
1. Insert ADLINK ALL-IN-ONE CD into your CD-ROM drive.
2. Because the ND-8511(D) configuration utility (Installer) need Microsoft
.NET Framework component for operation, please install the
component first. In the ADLINK ALL-IN-ONE CD, three versions of
Microsoft .NET Framework component are provided “ADLINK ALL-IN-
ONE CD -> NuDAM -> ND-8511 -> Microsoft .NET Framework”.
Please select the correct language version for your system.
3. Go to the “ADLINK ALL-IN-ONE CD -> NuDAM -> ND-8511” directory,
Click the ND-8511(D) configuration utility (Installer.msi) to open the
installation wizard window.
4. Respond to the installation wizard prompts.
2.1.2 Install the Patch
1. After installing the ND-8511(D) configuration utility (Installer), please go
to “ADLINK ALL-IN-ONE CD -> NuDAM -> ND-8511” directory and
click the patch file for the configuration utility (ND-8511.exe).
2. Installation wizard will ask you to set the installation directory of the
patch file, please make sure that the directory must be the same of

10 •Installation
the installation directory of the ND-8511(D) configuration utility
3. Respond to the installation wizard prompts.
2.1.3 RUN the Installer
1. Click the Start button on the Task Bar and select
“Programs\Installer\Installer” to start the ND-8511(D) configuration
utility. The utility main dialog box displays.
2. To search for devices, click the Search icon or select Search Network
from the Action menu. (The default settings are IP: 192.168.0.1, Net
Mask: 255.255.255.0, Gateway: 192.168.0.254. Users can change
host’s IP to 192.168.0.xxx to be the same Domain as the ND-8511, and
then click the Search icon to find the ND-8511).
2.1.4 Assign IP Address
After find ND-8511 as the description on Section 2.1.3, users can now
change its IP setting, and search for the ND-8511 again. The following
dialog box shows a device found on the network.

Installation •11
If the ND-8511(D) device doesn't show up after searching, then the device
might not have a valid IP address assigned. Please use the Assign IP
Address feature to set a specific IP address on the device. To do this,
please follow the procedures in “Section 2.1.8 Serial Port Login” to assign
the correct IP address.
To change the IP address, first select the device from the list, then click the
Assign IP icon or select Assign IP Address from the Action menu. The
hardware address and IP address are loaded into the Assign IP Address
dialog box.
Enter the new IP Address and click OK. The new IP Address will appear in
the main window.
2.1.5 Test the IP Address
To test the IP Address, select the device from the main window list, then
click the Ping icon, or select Ping from the Action menu. The Ping Device
dialog box shows the IP Address of the selected device. Click the Ping
button and the results will be displayed in the Status window. Use the Clear
Status button to clear the window so you can Ping the device again. Click
the Close button to close the dialog box and return to the main window.

12 •Installation
2.1.6 Opening a Configuration Window
To configure the unit via a Web browser, first click on one of the devices
listed in the window, then click the Web icon. The Web-Manager window
displays in your browser.
To configure the unit via a Telnet session, first click on one of the devices
listed in the window, then click the Telnet icon. The Setup Mode window
displays.
2.1.7 ARP and Telnet
The unit’s IP address must be configured before a network connection is
available. If the unit has no IP address, you can use Address Resolution
Protocol (ARP) method from UNIX and Windows-based systems to assign
a temporary IP address. If you want to initially configure the unit through the
network, follow these steps:
1. On a UNIX or Windows-based host, create an entry in the host's ARP
table using the intended IP address and the hardware address of the
unit, which is found on the product label on the bottom of the unit. arp -s
191.12.3.77 00:20:4a:xx:xx:xx
Note: For the ARP command to work on Windows 95, the ARP table on
the PC must have at least one IP address defined other than its own.
2. If you are using Windows 95, type ARP -A at the DOS command prompt
to verify that there is at least one entry in the ARP table. If the local
machine is the only entry, ping another IP address on your network to
build a new entry in the ARP table; the IP address must be a host other
than the machine on which you are working. Once there is at least one
