Chapter2 Basic Installation
2.1 Connecting the Hardware
1. Make sure that your USB devices are switched off and that the Server’s Power Adapter
is disconnected.
2. Connect the USB devices to the USB ports with the USB cables.
3. Connect the Server to the network with a twisted-pair category 5 cable, 10baseT or
100baseTX.
4. Turn on the USB devices and make sure it is ready for use.
5. Connect the Power Adapter to the Server. The power indicator will light up and USB1
and USB2 indicators will flash in turn. When the Link indicator lights up, the Server is
correctly connected to the network. When USB1 and USB2 indicators stop flashing, the
Server starts to work normally.
2.2 Wireless connection
This section only applies to DN-13021/DN-13023.
2.2.1 Preliminary
Before you can access wireless network, wireless parameters should be set correctly.
You have to setup the first wireless parameter set through LAN (wired) connection.
Wireless access can be set as infrastructure (station) mode, which need an access
point to route network messages with the same SSID.
Wireless access can be secured by WEP (64/128), WPA-PSA (TKIP/AES), and
WPA2-PSK (AES).
In infrastructure mode, if network administrator wants to change any security related
parameters, DN-13021/DN-13023 should be changed first, and then access point. If
parameters mismatch causes wireless access is not allowed, you have to modify those
parameters through LAN connection.
In infrastructure mode, the maximal transfer rate is 150 MBits depending on access
point’s capability.
2.2.2 Set Wireless Configuration Using Control Center
1. Install USB Device Server Control Center. It is available in the DN-13021/DN-13023 USB
Device Server Product CD.
2. Start USB Device Server Control Center and Auto-searching USB device server window
will appear.

6
3.
If the wireless parameters are not correct or not set yet, you have to use LAN to access USB
Device Server Control Center.
4. If the tool finds USB device servers in your local area network, then you have to select a
server from the server list.
5. Double click the highlighted server (or click the “Configure Server” button) to get the
server’s web pages. Click CONFIG icon.

7
6. Login with administrator ID (default: admin) and its password (default: admin).
7. Click Wireless icon.
8. In order to join an existing wireless network, you have to set the correct SSID, and the
correct security method with the correct key information.
9. If the wireless network is secured by WEP64 or WEP128, key index and WEP key must
be set correctly.

8
10. If the wireless network is secured by WPA-PSK or WPA2-PSK, the key formats, shared
key and encryption must be set correctly.

9
11. Click Submit to save your settings. And the server will reboot.
12. You have now finished the procedure of setting the wireless parameters.
After properly configuring the wireless parameters, you can remove the network cable and
reboot the DN-13021/DN-13023. DN-13021/DN-13023 will then connect to your wireless
network. DN-13021/DN-13023 will detect if a network cable is plugged-in or not. If a network
cable is plugged-in, DN-13021/DN-13023 will always connect to the network through the
network cable. Otherwise it will always connect to the network through wireless module. Once
DN-13021/DN-13023 connects to the network, either by network cable or by wireless module,
all operations to use USB device server are exactly the same.
2.3 Assigning an IP Address to the Server
2.3.1 Preliminary
If you have a DHCP server on your network, your Server will receive an IP address
automatically. The IP address will then appear on the Control Center or on the page of
configuration report that you printed earlier. If your DHCP server does not give an IP
address to the Server, the Server will use the automatic private IP addressing IP:
169.254.0.0. ~ 169.254.255.255
If you are not working in a DHCP network, you need to manually set the Server’s IP
address.

10
2.3.2 IP Address
Unless you are assigning an IP address using DHCP, you must obtain an unused IP address
from your network administrator.
2.3.3 Methods for Setting the IP Address
You can set the IP address of your Server using one of the following methods, depending on your
network operating environment:
Automatic IP Address Assignment
Manual IP Address Assignment
2.3.4 Setting the IP Address Using DHCP
Follow the instructions below to get an IP address using DHCP:
1. Edit or create a scope in the DHCP manager of the DHCP daemon. The entries included
in this scope should contain the following parameters:
range of IP addresses
subnet mask
default router IP address
DNS server IP address
lease duration
2. Activate the scope. The Server automatically gets the DHCP parameters. If you are using
DNS, you may include at least one DNS server IP address in the DHCP scope or manually
set the DNS server IP address using Server’s web pages or the Control Center.
2.3.5 Setting the IP Address Using the Control Center
1. Install the Control Center. The Control Center is available on the Product CD.
2. Start the Control Center and Auto-searching Server window will appear.
3. If the tool finds multiple Servers in your local area network, then you have to select one
Server from the Server List.

11
4. Double click the highlighted server (or click the “Configure Server” button) to get the
server’s web pages. Click CONFIG icon.
5. Login with administrator ID (default: admin) and its password (default: admin).

12
6. Click the button corresponding to your choice of IP setting methods (static or dynamic
using DHCP). When assigning a static IP address you also have to define Subnet Mask.
7. Click Submit to save your settings. And the Server will reboot. You have now finished the
procedure of setting the IP address.

Chapter3 Using the USB Device Server
3.1 Introduction
The goal of this produce is to provide the USB device server in a single product. We developed a
new technology called “NetUSB” to achieve this goal. Basically, the “NetUSB” is a “USB over IP”
technology that transparently redirects all USB packets to TCP/IP network channel. “NetUSB”
allows you to use USB devices as if they were connected directly to your PC although they are
actually remotely connected to the USB device server.
3.2 Connect & Disconnect
“NetUSB” allows you to use USB devices as if they were connected directly to your PC although
they are actually remotely connected to the USB device server. The “connect” operation is a
software operation that simulates an actual USB device plug-in. That is to say, when you do a
“connect” operation in the Control Center, PC can then detect a USB device’s plug-in, although
actually you do not plug in any USB device. Similarly, the “disconnect” operation is a software
operation that simulates the disconnection of the USB device. Once the connect operation is
successful, the operations to use that USB device are just the same as if the USB device is
directly connected to the PC.
If a USB device is “connected” by a PC, we say that PC has the ownership of the USB device.
Only one PC can get the ownership of a USB device at the same time. Therefore, if a USB
device is connected by one PC, no other PC can connect this USB device until this USB device
is disconnected.
3.3 Subnet Issue
Before using the NetUSB technology, you must first make sure that your PC can access USB
device server via TCP/IP. The simplest way to do this is using “Control Center” to search for the
USB device server on the network and change its IP address to be the same subnet as your PC.
If the server and your PC are not in the same TCP/IP subnet, Control Center will show the server
in red, as the following figure. You must change the IP address (or using DHCP) of the server so
that the server and your PC are in the same subnet. Control Center will show these servers in
blue, meaning you can access these servers by the NetUSB technology.

3.4 Installation of USB Device Driver
Some USB devices, like printers or MFPs (multifunction printers), require to install
vendor-supplied driver (usually on CDROM). For those USB devices that do not need to install
driver, please skip this section.
A. Insert the CDROM into the CD drive and run the “autorun” program.
B. Follow the instructions of the installation program to install driver.
C. When the installation program asks you to plug-in the USB device, run the “Control Center”.
D. In the Control Center, click the USB device server that has the desired USB device
attached.
E. Click the desired USB device as the following figure.
F. Click the “Connect” button. Then the message “Manually Connect by
your_computer_name” will be shown, as the following figure.

15
G. Now, the installation program will detect the USB device and continue to install driver.
H. After the installation is completed, click the USB device in the Control Center and then click
the “Disconnect” button to disconnect the USB device.
Now the driver of your USB device is installed.
3.5 Using the USB Device Server
A. In the Control Center, click the USB device server that has the desired USB device attached.
B. Click the desired USB device.
C. Click the “Connect” button. Then the message “Manually Connect by
your_computer_name” will be shown.

16
D. Now, PC will detect the plug-in of the USB device. The “connect” operation is a software
operation that simulates an actual USB device plug-in. That is to say, when you do a
“connect” operation in the Control Center, PC can then detect a USB device’s plug-in,
although actually you do not plug in any USB device.
E. Then, just use the USB device as if it is connected directly to your PC’s USB port.
F. After you finish using the USB device, click the USB device in the Control Center and then
click the “Disconnect” button to disconnect the USB device. Other PCs can not “Connect”
the USB device until you “Disconnect” that USB device. That is to say, only one PC is
allowed to connect the USB device at the same time.

17
3.6 Auto-Connect Printer
The method described in section 4.5 is so-called manual-connect, which means users must
manually connect the USB device before using that device, and must manually disconnect the
USB device after using the device, otherwise nobody else can connect this device. However, for
printers and scanners (and MFPs), the USB device server supports auto-connect so users don’t
need to manually connect/disconnect. This and the next sections show you how to do this.
After the driver is installed as described in section 4.4, you can see a newly created printer in the
Control Panel’s “Printers and Faxes”. Follow the steps below to do a NetUSB auto-connect
printing.
A. In the Control Center, click the USB device server that has the desired printer (or MFP)
attached.
B. Click the desired printer (or MFP).
C. Click the “Auto Connect Printer” button and choose “Set Auto-Connect Printer”.
The following figure will appear.

18
D. Choose the desired printer. The desired printer must be the Windows printer (this is a logical
printer) that matches the printer attached on the USB device server (this is a physical
printer). Then click the “Apply” button.
E. Then, the printer will be marked as an “Auto-Connected Printer” in red. If you choose
“Auto-Connected Printer List” in the “Tools” menu, you can see a newly created item that
describes the association between the Windows printer and the physical printer on the
server.

19
F. Then try to issue a print job to the desired printer. You will see the Control Center will
automatically do a connect operation. Then, the print job will be issued to that printer.
G. Even you already properly setup an auto-connected printer, the Control Center must be
running (in the background) while a print job is issued. This means you’d better run the
Control Center every time after you login Windows. In order to skip this manual operation,
you can make the Control Center be run automatically after you login Windows. To do this,
choose the “Configuration” item in the “Tools” menu. The following window will appear. Click
on the check box and then on the “OK” button. This feature is enabled by default.
If you would like to break the association between the Windows printer and the physical printer,
just click on the association and click the “Delete” button in the “Auto-Connected Printer List”.

3.7 Network Scanner
For NetUSB scanning, we recommend you use Network Scanner as the following steps.
A. In the Control Center, click the USB device server that has the desired MFP (or scanner)
attached.
B. Click the desired MFP (or scanner).
C. Click the “Network Scanner” button. Then you can see that the Control Center will
automatically do a “connect” operation. The following window will appear.
