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, 100baseTX and
/1000Base-T RJ-45.
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. (For 601/601n, only USB1 indicator will flash.) 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.
3.2. Wireless connection
This section only applies to 601n/604n/612.
3.3.1. 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 an access need 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, 601nv2/604nv2/612 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.
3.3.2. Set Wireless Configuration Using Control Center
1. Install USB Device Server Control Center. It is available in the 601n v2/604n v2 /612 USB Device
Server Product CD.
2. Start USB Device Server Control Center and Auto-searching USB device server window will appear.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
If the wireless parameters are not correct or not set yet, you have to use LAN to
access USB Device Server Control Center.
3. If the tool finds USB device servers in your local area network, then you have to select a server
from the server list.
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).

10. Click Submit to save your settings. And the server will reboot.
11. 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
601n/604n. 601n/604n will then connect to your wireless network. 601n/604n will detect if a network
cable is plugged-in or not. If a network cable is plugged-in, 601n/604n will always connect to the network
through the network cable. Otherwise it will always connect to the network through wireless module.
Once 601n v2/604n v2 /612 connects to the network, either by network cable or by wireless module, all
operations to use USB device server are exactly the same.
3.3. Assigning an IP Address to the Server
3.3.1. 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.
3.3.2. IP Address
Unless you are assigning an IP address using DHCP, you must obtain an unused IP address
from your network administrator.
3.3.3. 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
3.3.4. Server Names and Server Name Rules
The default server name of the Server is “KC601” (for 601) or “KC601n” (for 601n) or “KC604n” (for 604n)
or “KC611” (for 611) or “KC612” (for 612) or “KC612ac” (for 612ac). If you put two or more Servers in
your local area network, to avoid using the same server names you have to change the server names by
using the Control Center or the Server’s web pages. If your server name is longer than 15 characters, the
Server uses only the first 15 characters.

3.3.5. 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.
3.3.6. 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.
4. Double click the highlighted server (or click the “Configure Server” button) to get the server’s web
pages. Click CONFIG icon.

Chapter 4 Using the USB Device Server
4.1. 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 601/601n/604n/611/612 USB device server.
4.2. 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 601/601n/604n/611/612/612ac 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.
4.3. 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.

4.4. 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.
1. Insert the CDROM into the CD drive and run the “autorun” program.
2. Follow the instructions of the installation program to install driver.
3. When the installation program asks you to plug-in the USB device, run the “Control Center”.
4. In the Control Center, click the USB device server that has the desired USB device attached.
5. Click the desired USB device as the following figure.
6. Click the “Connect” button. Then the message “Manually Connect by your_computer_name” will
be shown, as the following figure.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
7. Now, the installation program will detect the USB device and continue to install driver.
8. 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.
4.5. Using the USB Device Server
1. In the Control Center, click the USB device server that has the desired USB device attached.
2. Click the desired USB device.
3. Click the “Connect” button. Then the message “Manually Connect by your_computer_name” will
be shown.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
4. 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.
5. Then, just use the USB device as if it is connected directly to your PC’s USB port.
6. 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.
4.6. 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.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
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.
1. In the Control Center, click the USB device server that has the desired printer (or MFP) attached.
2. Click the desired printer (or MFP).
3. Click the “Auto Connect Printer” button and choose “Set Auto-Connect Printer”.
The following figure will appear.
4. 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.
5. 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.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
6. 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.
7. 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.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
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”.
4.7. Network Scanner
For NetUSB scanning, we recommend you use Network Scanner as the following steps.
1. In the Control Center, click the USB device server that has the desired MFP (or scanner) attached.
2. Click the desired MFP (or scanner).
3. Click the “Network Scanner” button. Then you can see that the Control Center will automatically
do a “connect” operation. The following window will appear.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
4. Choose one of TWAIN or WIA item. Click “OK”. The following window will appear.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
5. Follow the usual steps to do scanning.
6. After the scanning, close the “Auto-Connect Scanner” window. At this moment, Control Center
will automatically do a disconnect.
4.8. USB Storage
You must use “manually connect” for USB storage. After you connect a USB storage, like the following
picture, your PC will have a new disk. If the USB storage is a flash drive, the new disk is a “removable disk”.
You can see the storage icon in the system tray.
Then just use the new disk as a general disk. After you finish the disk operations, click the storage icon in
the system tray and choose “Safely remove USB Mass Storage Device” to remove the USB storage, as the
following figure.
Then, in the Control Center, click the USB storage device and click the “Disconnect” button to disconnect
the USB storage device.

© 2019 KCodes Corporation. All rights reserved. 6 Series User’s Manual V1.0
4.9. Request to Connect
If a USB device is manually connected by any other user, basically you can not connect that device.
However, we offer another mechanism called “Request to Connect” to solve this inconvenience. For
example, there are two computers –TESTES and TEST. Now the owner of “HP Photosmart 2600” is TEST.
Then, the TESTES computer wants to use this HP printer. The user on the TESTES computer can click the
“Request to Connect” button in the Control Center. The following window appears.
At this moment, the user on the TEST computer will see the following window, indicating that another
computer –TESTES is requesting to use the HP printer.
The user will choose to accept or reject. If accepted, the Control Center on TEST will automatically
disconnect the device and the Control Center on TESTES will automatically connect that device.
