HDD Mode Menu
In addition to ejecting the hard drive caddy and connecting it to a PC or Mac via USB you can also connect
the DN-400 directly to a computer via an IEEE-1394 FireWire connection.
Some important things to be aware of before using this feature of the DN-400. Connecting 2 or more
IEEE-1394 devices to a computer at the same time may cause problems with the FireWire communication.
To avoid this please remove any other IEEE-1394 connections from the DN-400 and the computer first. Also
FireWire connections do not work reliably over long distances so keep the cable length short, under 5m.
IEEE-1394 6pin Power; ensure the cable connector is inserted the correct way around otherwise short circuit
damage may result to either the computer or the DN-400 port.
HDD Mode Menu will set the DN-400 up as an external IEEE-1394 (Firewire) drive, for direct drag and drop
file transfer to a PC or MAC. The DN-400 drive will show up on the desktop of the MAC or in the My
Computer window of a Windows PC. The recorded files appear in the root directory of the DN-400 drive, and
are numbered with the track number that appears in the LCD display when you are recording or playing back
the track.
The DN-400 uses a FAT32 file structure, so large tracks are broken down into 2 GB files which are named in
sequence. For example if Track 02 is 1 hour in duration it will appear as follows:
dv02.dv (2 GB) - dv02 is the file name for Track 02
dv02_01.dv (2 GB) - Each 2 GB section is given a sequential _xx numeric extension
dv02_02.dv (2 GB)
dv02_03.dv (2 GB)
dv02_04.dv (2 GB)
dv02_05.dv (2 GB)
dv02_06.dv (77 MB) - The last file in the sequence is likely to be smaller than 2GB.
Connecting to a PC / MAC
NB: Although your PC / MAC may see the DN-400 as an AVC compliant DV Device it is not intended to be
operated as such. The AVC command set is not supported.
Connect the DN-400 IEEE-1394 output to a PC or MAC.
To set the DN-400 into HDD Mode firstly press the Menu button so that it is illuminated.
You will see the display change to the HDD Mode Menu.
Press the Next (▲) Button to select ENTER and the display will show the HDD Enable Confirmation Screen

The PC / MAC should recognise that an external IEEE-1394(FireWire) HDD has been connected.
The DN-400 can then be used like an external drive.
See Connecting to a PC / Connecting to a MAC for more details.
To return the DN-400 to front panel VTR Mode either use “Safely Remove Hardware” with a PC, or with a
MAC use “Eject” or Drag the DN-400 Drive Icon to “Trash”. Once un-mounted the DN-400 display will return
to Track Display.

DV devices can sometimes conflict with one another, it is not a common occurrence but it can happen. When
conflicts occur one DV device may not recognize the other, or the output from one is switched off by the
other. “Set Full Syt” will overcome conflicts of this type, so if you have a conflict with another DV device
switch Set Full Syt to Enable. See also Set Channel Output menu.

Convert DV to AVI Menu
The DN-400 has a built in file conversion utility which can convert .dv files to .avi files (type 1 or type 2). You
can choose the format that best suits your Non Linear Editing platform.
HDV (.M2T) Tracks cannot be converted to .avi files by the DN-400 or with the supplied software.
N.B. Check free space first the DN-400 requires enough free drive space to create a converted .avi
file. For example a 1 GB .dv file will require at least another 1 GB of free space on the DN-400 drive for the
.avi file to be created. The converted AVI file will not be displayed on the track list, but it will be available to
drag and drop to a computer for editing etc.
The conversion takes about 60% real time, i.e. A 1 hour track will take around 36 minutes to convert.
N.B. You can convert files more quickly using the DV File Converter program that is supplied with the
DN-400, see page 33 for more details.
Press the Menu Button, to enter menu mode
Press the REW (◄◄) Button to navigate the menus until CONVERT DV TO AVI is displayed
Press the Next (▲) Button to enter the CONVERT DV TO AVI menu

The conversion process will start - once complete CONVERSION DONE will be displayed
Press the Next (▲) Button to select OK - and then press the Menu Button to exit.

Set Output Channel Menu
Occasionally DV device outputs will conflict. It is not a frequent occurrence but when it happens it is possible
to change the Output Channel of the DN-400 to overcome the conflict. For example if another DV device has
the same output channel as the DN-400 this will result in a conflict, which will mean that the DN-400 output is
blocked. Please change the output channel of the DN-400 to solve the problem.
The default output channel of the DN-400 is 1, this is fine for recording from a DV Device and monitoring /
playing back to an analogue monitor. However, if you want to output DV from the DN-400 into another DV
Device you may need to select channel 63 here instead.
N.B. When the DN-400 is set to channel 63 you cannot playback a track to analogue outputs, until the
connected DV device (camera, mixer etc) is switched off or disconnected.
Press the Menu Button, to enter menu mode
Press the REW (◄◄) Button to navigate the menus until SET OUTPUT CHANNEL is displayed
Press the Next (▲) Button to enter the SET OUTPUT CHANNEL menu
Use FWD (►►) or REW (◄◄) to change the output channel number - in this case we have selected 1
Press the Next (▲) Button to confirm the setting
Then press the Menu Button to leave menu mode
Scan HDD Surface Menu
Hard Disk Drive Surface scan is a utility which checks the disc surface for errors and bad sectors. It is not

changed the removable drive.

To run Surface Scan press the Menu Button to enter menu mode.
Press the REW (◄◄) Button to navigate the menus until SCAN HDD SURFACE is displayed
Press the Next (▲) Button twice to start the HDD Surface Scan.
