1. Product Description
01 PRODUCT DESCRIPTION PRODUCT DESCRIPTION 02
The NEXTO VIDEO STORAGE pro (hereinafter NVS2501) includes a 2.5”Serial ATA
(SATA) hard drive and a Li-Poly battery. The NVS2501 provides the following
functions:
1. Memory card backup
The NVS2501 contains a 2.5”SATA hard drive and a Li-Poly rechargeable battery.
The NVS2501 can copy the contents of a memory card to the internal hard drive
without a PC--even in the field where no electric power source is available.
You can copy SxS cards and Cardbus memory cards (including P2/P2E)
(using a CardBus Memory card adapter) through the ExpressCard slot
on the left side of the device. You can copy through the Cardbus slot on the top
of the device.
For IKEGAMI GFPAK, you can copy through the eSATA_host/USB_host combo port
on the bottom of the NVS2501.
For complete backup information, refer to Chapter 11 of this manual.
2. Video/Photo Preview
The NVS2501 can display video footage taken with professional video cameras,
such as the XDCAM or P2CAM, on a color TFT LCD. The NVS2501 provides a
“best effort” preview of the video clip--that is, the resolution and speed may be
lower than on a regular device. For details on Video Preview, see chapter 12.
3. Multi-Copy
NVS2501 can copy the contents of a memory card to the internal hard drive and
an USB external hard drive at the same time, allowing you to make two copies
in a single operation using this function.
For details of the Multi-Copy feature, see chapter 14.
4. Sync
The NVS2501 can synchronize the contents of a folder with the folder on an
USB external hard drive. This allows you to make a secondary copy of
the backup folder to an USB external hard drive without using a computer.
For details of the Sync function, see chapter 15.
5. Computer connection
The NVS2501 can be connected via USB2.0, eSATA, FireWire 800 (IEEE 1394b) to
a corresponding port on a computer, in order to copy data.
For details of Computer Connections, see chapter 10.
6. Button operation
All of the functions of the NVS2501 are controlled by two buttons, one for power
(On/Off) and the other for function control (control key). The power button can
also be used as a function key in some instances.
For details on Power (On/Off) and control key operation, see chapter 8.
7. Bad Sector Recovery
When a video file stored in the NVS2501 cannot be copied or edited on
a computer, the problem may be a bad sector on the hard drive. The NVS2501
has a sector recovery function which may recover the video file.
For details on Sector recovery, see chapter 16.
8. Internal/External rechargeable battery
The NVS2501 contains an internal Li-Poly battery that enables the NVS2501 to
be used without the power adapter. The power adapter is used to charge
the internal battery, supplying power to the main unit. The external battery
can be used to charge the internal battery.
For details on Charging the Internal Battery, see chapter 7.
9. Internal hard drive
The NVS2501 offers these functions for the internal hard drive:
[Hard drive format]
[Hard drive capacity check]
[Hard drive self test]
For details see chapter 9 and chapter 17.
10. Firmware upgrade
When NextoDI develops new functionality—or offers support for new video
formats--firmware is provided to users through the website’s download page.
You can download the new firmware to a memory card or the internal hard
drive of the NVS2501. You can then upgrade your NVS2501 using the firmware
update function of the NVS2501. For details, see chapter 17.

6. About the Rechargeable Battery
A "Li-Poly" (lithium-polymer) rechargeable battery is integrated into the NVS2501.
This rechargeable battery does not have the so-called "memory effect"--
the rechargeable battery can be charged whenever you want. Furthermore,
it has a higher energy content than conventional NiCd and NiMH rechargeable
batteries. Note these important instructions when handling the Li-Poly
rechargeable battery.
The rechargeable battery can be recharged 400 times.
If the battery operation time gets shorter, it may be time to replace the battery.
Consult your authorized NEXTODI dealer to replace the internal battery.
Caution
● Never damage the rechargeable battery--do not remove it from
the NVS2501. Consult the chapter on "Battery Disposal". Damaging
the wrapping of the rechargeable battery might cause an explosion
or fire.
● Never short circuit the contacts of the rechargeable battery. Never
touch the connections or electrical components inside the NVS2501
with metal objects.
● Charge the rechargeable battery regularly, even if you do not use
the product. The NVS2501 needs some "current" (a small quantity)
at all times. Due to the Li-Poly rechargeable battery technology,
it is not necessary to discharge the battery before recharging.
Recharge the battery completely, about once a month. The device
will be ready for use at any time.

09 CHARGING THE RECHARGEABLE BATTERY NVS2501 INTERFACE 10
7. Charging the Rechargeable Battery
1. Internal battery
The battery can be charged using the AC power adapter unit delivered with this
product.
①Turn off NVS2501.
②Connect the charger’s wall plug to the NVS’s "DC IN" slot.
③Plug the AC power adapter unit into a wall socket.
④The LED above the Control key shows red during the charging.
⑤When the battery is charged, the red LED turns off.
⑥If there is an error when charging, the LED blinks. If this happens,
unplug the AC adapter unit and plug it in again.
Users can charge the NVS2501 via the USB/FireWire 800 (IEEE 1394b) cable,
or the AA battery holder.
With a completely empty rechargeable battery, the charging procedure lasts
approximately 4 hours using the AC power adapter, or the FireWire 800 (IEEE
1394b) cable. With the USB cable, charging takes about 7 hours.
With the AA battery holder, charging takes about 10 hours. An AA battery pack
charges about 40% of the internal battery capacity.
Reference
● You must turn off the NVS2501 in order to charge the unit.
● The NVS2501 can be charged via USB without using the AC power adapter
included in the box. A high powered USB connection is needed, i.e. a USB
connection with its own power supply, such as the USB port of a computer or
a USB hub with a power unit.
● If the NVS2501 is operated with a notebook, you must always use the AC
power adapter unit to charge the NVS2501. Notebooks may not deliver the
necessary amount of current via USB
● The NVS2501 will operate for about two hours with a fully charged internal
battery.
● When connected to a computer using FireWire 800 (IEEE 1394b) or USB,
the NVS2501 draws power from the computer, not the internal battery.
● If the NVS2501’s battery is completely discharged, the performance of
the battery may be degraded. It is recommended that the NVS2501’s battery
be recharged before the battery gauge reaches the empty level.
● See Chapter 8 for more information on the battery gauge.
Caution
● Car charger cable should be used only for charging the internal
(or external) battery.

Back up data is stored in the "NVSPRO" folder. This
folder is created automatically. The NVS2501
generates a new folder for each memory card copy.
The name of the folder is determined by the shooting
date.
For example, 20081112.000 means the last footage
recorded on November 12, 2008. (If you copy
multiple items on a single day, the last three digits
will be changed to indicate the download sequence –
“000, 001,002, 003, etc.) The date code comes from
the video cameras. If the date setting on the video
camera is incorrect, the folder name of NVS2501 will
also be incorrect.
If a copying failure occurs, the copy is stored on your
computer as a TMP folder. The TMP folder contains
the same file names, but the data may be abnormal.
You may delete the TMP folder.

11. Data Backup(Copy) and Verify
This chapter represents the ‘Copy’ and ‘Verify’ functions.
Insert a memory card into the corresponding memory slot.
The slot for CF/MD/SDHC/SDXC/MS is located on the top side of the NVS2501.
The slot for the SxS card is located on the left side of NVS2501.
The Cardbus memory card (including P2/P2E cards) must be used with a CardBus
memory card adapter which is included in the NVS2501 box.
The Ikegami GFPAK flash memory device can be connected via the “eSATA/
USB-Host” combo slot using the USB cable.
When copying from a memory card, the NVS2501 must not be connected to
a computer. The NVS2501 can copy a memory card onto the internal hard disk via
the built-in memory slot or via the "eSATA/USB-Host" combo slot connector
with a USB cable. After the backup, the copy procedure can be verified. The data
on the memory card and the data on the hard disk are compared with one another.
This ensures that the data has been copied properly (“Verify”). You can choose
the “New Copy” or the “Verify” function according to whether the contents of
the memory card have been copied before.
● Do not connect more than one memory card or USB external HDD to
the NVS2501. Only the first one connected will be detected.
● Insert the memory card carefully. The pin may get bent if you insert
incorrectly.

When you choose the verify function, the NVS2501
compares the data stored on the hard drive to that
on the memory card. The verification logic entails
a full bit-by-bit verification, and detects any
differences.
: For verification, press the control key briefly
: Another option: press the control key for more
than 2 seconds. Select to make one more copy
of this memory card.
Two options are available for verification using left/right key selection.

The data on the memory card is compared with
the data stored on the NVS2501 hard disk to
determine whether it is new data or if the data or
a portion of the data has already been stored on
the NVS2501. According to the comparison result,
the NVS2501 operates as follows:
Make new folder and copy all the memory card data into the folder.
Before copying data, the NVS2501 verifies that its hard drive area is
safe. If a bad sector is detected, a new, safe area is found –
then copying [Fast Copy] will begin.
Fast Copy
Verify&Copy
Same as [Fast Copy] but after copying, the data on the memory card
is compared with the copied data in the NVS2501 hard drive. Each
bit is verified.

The NVS2501 allows a user to copy a memory card to both the NVS2501 hard drive
and to an USB external hard drive at the same time, making two copies of data
in a single operation. The NVS2501 provides “Multi-copy” and “Sync” functions
to make backup more reliable. Users can also choose to copy from an external USB
device (USB HDD / USB Card Reader) to the NVS2501 internal hard drive.

31 USING AN EXTERNAL HARD DRIVE MAKING TWO COPIES IN SINGLE BACKUP(MULTI-COPY) 32
Copying a memory card to both the internal hard drive and an external USB hard
drive at the same time makes two copies of data in a single operation.
The “Multi-copy” function of the NVS2501 makes backup more reliable.
14. Making Two Copies In A Single Backup(Multi-Copy)
If the proper external hard drive is connected,
the NVS2501 shows information about the drive.
Quickly [S] press the key or wait 10 seconds--
the NVS2501 will automatically go into the
“Multi-Copy” mode. (If the external USB hard
drive connects before the power is on,
the NVS2501 will go directly into “Multi-Copy”
mode)
The remaining operation is the same as the
“XCopy ready” mode. This mode can be exited
by holding and pressing the key or by removing
the USB cable from the NVS2501.
Insert the memory card when you are in the
“MCopy ready” mode. The NVS2501 detects/
parses the contents of the memory card and
asks you to confirm the mode of copy. Three
options are available as in the normal XCopy
mode. For details, see chapter 11.
: Copy: briefly press the key.
: Cancel the copy: press and hold the key
for more than 2 seconds.

Move to “SYNC” on the main menu and
select it.
Connect the USB external hard drive to the
[eSATA/USB-Host] combo port of the
NVS2501 as shown in chapter 13.
The “Sync” function synchronizes data between the [NVSPRO] folder of the
NVS2501 and the [NEXTO] folder of an external USB hard drive connected on the
“eSATA/USB Host” connector via USB cable. This function compares the folders
stored in the [NVSPRO] folder of the NVS2501 and the [NEXTO] folder of an
external hard drive. A new folder will be copied to the external hard drive only
if a folder is in the [NVSPRO] folder of the NVS2501—but not in [NEXTO] folder of
an external hard drive.
