About File Sharing
Workgroup name
This is the name given to a set of computers that are connected on a network and share resources
such as a printer or files. Windows automatically assigns the workgroup name when you set up a
network.
Shares
When settings are set to default, each USB device connected to the Device is given a folder, called
a “share”. If a USB hard drive connected to the Device has more than one partition, then each
partition will be allocated a share. You can also configure a “share” to be a sub-folder or file on the
USB device.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often
different operating systems such as Windows or Linux have different file systems. The file sharing
feature on your Device supports File Allocation Table (FAT) and FAT32.
Common Internet File System
The Device uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS
compatible computers can access the USB file storage devices connected to the Device. CIFS
protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to
your systems specifications for CIFS compatibility).
16.1.2.2
About Printer Server
Print Server
This is a computer or other device which manages one or more printers, and which sends print jobs
to each printer from the computer itself or other devices.
Operating System
An operating system (OS) is the interface which helps you manage a computer. Common examples
are Microsoft Windows, Mac OS or Linux.
TCP/IP
TCP/IP (Transmission Control Protocol/ Internet Protocol) is a set of communications protocols that
most of the Internet runs on.
Port
A port maps a network service such as http to a process running on your computer, such as a
process run by your web browser. When traffic from the Internet is received on your computer, the
port number is used to identify which process running on your computer it is intended for.

9100) protocol.
The following OSs support Device’s printer sharing feature.
Microsoft Windows 95, Windows 98 SE (Second Edition), Windows Me, Windows NT 4.0, Windows
2000, Windows XP or Macintosh OS X.

Before You Begin
Make sure the Device is connected to your network and turned on.
1
Connect the USB device to one of the Device’s USB port. Make sure the Device is connected to your
network.
2
The Device detects the USB device and makes its contents available for browsing. If you are
connecting a USB hard drive that comes with an external power supply, make sure it is connected
to an appropriate power source that is on.
Note: If your USB device cannot be detected by the Device, see the troubleshooting for
suggestions.

The Media Server Screen
The media server feature lets anyone on your network play video, music, and photos from the USB
storage device connected to your Device (without having to copy them to another computer). The
Device can function as a DLNA-compliant media server. The Device streams files to DLNA-compliant
media clients (like Windows Media Player). The Digital Living Network Alliance (DLNA) is a group of
personal computer and electronics companies that works to make products compatible in a home
network.
The Device media server enables you to:
Publish all shares for everyone to play media files in the USB storage device connected to the
Device.
Use hardware-based media clients like the DMA-2500 to play the files.
Note: Anyone on your network can play the media files in the published shares. No user
name and password or other form of security is used. The media server is enabled
by default with the video, photo, and music shares published.
To change your Device’s media server settings, click
Network Setting > USB Service
> Media
Server
. The screen appears as shown.
