Problems While Using DS-510

This page explains the troubleshooting procedures to resolve problems you may experience while using DS-510.



The USB device is not displayed in SX Virtual Link.

If the USB device is not displayed in SX Virtual Link, you need to check the cable connection as well as the network settings between DS-510 and your computer.

Solution Please check the LED status of DS-510 and the Ethernet Hub DS-510 is connected to. If the LED indicates improper status, replace the AC plug and other cables, and reboot the connected devices.

Solution It takes up to 30sec for DS-510 to get ready after it is powered on. Please wait until DS-510 becomes ready and then click the Refresh button in SX Virtual Link again.

Solution Please add SX Virtual Link to the exception list in your security software. Please refer to the FAQ on our website ( https://www.silextechnology.com/ ) for details on adding an application to the exception list.

Solution First, check the IP Address of your computer.
To check the IP Address, use the Windows Command Prompt.
  1. Select Start - All Programs - Accessories - Command Prompt.
  2. When the Command Prompt is started, execute the ipconfig command.
Example of executing the ipconfig command

Microsoft Windows [Version 6.1.7601]

C:\Users\username>ipconfig (Press Enter)

       IPv6 Address . . . . . . . . . . . . . . . . : 2001:db8::x:x:x:x
       Temporary IPv6 Address. . . . . . . . : 2001:db8::z:z:z:z
       Link-local IPv6 Address. . . . . . . . . : fe80::x:x:x:x%4
       IPv4 Address . . . . . . . . . . . . . . . . : 192.168.0.10 (IP address of computer)
       Subnet Mask . . . . . . . . . . . . . . . . : 255.255.255.0
       Default Gateway . . . . . . . . . . . . . . : fe80::x%4
                                                             192.168.0.254

Check that the IP Address of the computer is a proper address for communicating with the IP Address of DS-510.
If the computer and DS-510 are in the same network segment but use a different network number in their addresses, you need to change either the address of the computer or DS-510. Also, if there is a router between the computer and DS-510, check that the default gateway address is properly configured.

Solution First, turn off DS-510 and open the Windows Command Prompt.
Ping the IP address of DS-510.
  1. Select Start - All Programs - Accessories - Command Prompt.
  2. When the Command Prompt appears, execute the ping command.
Example of executing the ping command when the IP address of DS-510 is 192.168.0.20

If there is a reply while DS-510 is turned off, it means there is another network device using the same IP address as DS-510. In such a case, change the IP address of either DS-510 or the other network device.

Solution Check the LEDs on the USB device to see if it is powered on.  If the USB device is not powered on, confirm the AC adaptor is connected properly.
Also, if the USB device is a bus-powered device, it may require power exceeding the maximum power capability of DS-510 (e.g. HDD drive, etc.).   In that case, please use the AC adaptor bundled with the USB device.


Solution Please see the Web page of DS-510.
If the message "An over-current was detected and the USB port shut down. Please reboot the device server." is displayed, Bus power has been cut off.
In such a case, unplug all USB devices from DS-510 and reboot it.

If you are using USB devices that run on USB Bus power, it is recommended to avoid using two or more devices at once, so that the total power used does not exceed the maximum power capability of DS-510.

Solution Please confirm the proper cable connection between DS-510 and the USB devices. If there is a spare USB cable, replace the cable and see how it works.


An error occurs after USB device is connected using SX Virtual Link.

When USB devices are properly displayed in SX Virtual Link but an error occurs when they are connected, you need to check the USB device specification as well as the computer settings.

Solution Please connect the USB device directly to your computer and see how it works. If the USB device still does not work properly, the device driver may not have been installed to your computer correctly. See the operation manual that came with the USB device and re-install the device driver again.


DS-510 does not switch to ECO Mode even though the specified time period has passed.

Solution Please make sure that the "ECO Mode" setting is set to ENABLE.
For details on the ECO Mode setting, refer to Extended Settings.

Solution Because SX Virtual Link regularly communicates with DS-510, DS-510 will not switch to ECO Mode if SX Virtual Link is running.

To allow DS-510 to switch to ECO Mode, shut down all computers with SX Virtual Link installed or close SX Virtual Link on each computer. For details, refer to About ECO Mode.


Printing using the print server feature does not function.

Solution When the IP address of DS-510 changes, please also change the corresponding printer port setting on Windows.

When using the print server feature, it is recommended that you set a static IP address to DS-510 or set your DHCP server to always assign a static address to DS-510.

Solution Please restart DS-510 if you have changed the USB port your printer is connected to while in ECO Mode.


Frame dropping or sound skipping occurs when I use a Web camera or USB speaker.

Solution When you use isochronous devices such as Web camera, USB speaker, etc, please connect them directly to DS-510.

Solution For isochronous devices such as Web cameras or USB speakers, etc, it is recommended to use a Gigabit Ethernet network.
