NETmc Marine DVRi Manual rev. 5.3 May 2010 2 of 43
1. Introduction
NETmc Marine has been designing and manufacturing digital video recorders (DVR) since the late
1990s. The DVR Inspector range, which includes the portable DVRi Peli, is its top of the range
single channel recorder specifically designed for the offshore survey, ROV and commercial diving
markets.
The DVR Inspector is designed to encode standard composite video signals, either PAL or NTSC, in
to fully compliant MPEG 1 or MPEG 2 digital video files. These single channel DVRs are robust,
simple to use, rack mountable and have a proven track record of reliability. Audio can be included
in the video files by plugging a microphone into the appropriate socket on the rear of the unit. The
complete video file is then stored directly to hard drive; the hard drive can be the internal drive, an
attached drive or, when available, the removable SATA drive. As the units are all fitted with USB
and network connections, the external drive can use either of these modes of connection.
The quality of the video files is selectable in the setup screen, where the required format (MPEG 1
or 2) and bit rate (1-6 Mbps) can be chosen.
For those users requiring more portability, NETmc Marine supplies the DVRi Peli – a single channel
portable, robust unit which incorporates a built-in high resolution monitor, keyboard and mouse.
DVRi Peli units are ideal for diver or mini ROV operations.
NETmc Marine’s range of equipment also includes a variant of the DVR Inspector designed to
accept an HD SDI signal from the new HD cameras that are now becoming available. This unit
converts the HD signal to SD MPEG: in this way the ROV pilot sees the high definition picture, but
the size of the video files created is the same as with standard composite, ensuring that the files are
readily transferable / playable on any PC. However, as the signal going to the encoder is so good,
the image at SD MPEG is far better than with a composite input.
All of the products in this range can be used as stand-alone recorders. The controls are simple and
operation could not be easier. However, it is when these products are integrated with external
software packages, such as Coabis, Scope or E-Inspect, that their flexibility becomes apparent.
Such software packages turn the DVR Inspector range of products into high level inspection tools,
where file naming, selection of storage location and control of the recorder are all done remotely
over a network.
Digital video recording is fast becoming the industry standard for video acquisition and the DVR
Inspector range of products is now the DVR of choice for many oil companies and inspection
companies for the production of integrated video and data in the structural integrity monitoring
market.

2. System Description
2.1 DVR Inspector. Hardware Description and Connections
The DVRi is a single channel rack mountable recorder running on a Windows platform. It is housed
in 2U high casing and encompasses a removable hard disk drive accessed via the front panel; other
hard drive options are available. All connections to the recorder are on the rear panel as shown
below, as is the on/off button for the internal power supply unit and the cooling fan outlet. The power
supply switch must be in the on (1) position for the recorder to function; it is good practice, but not
essential, to switch the internal power supply off when the recorder is not in use.
NOTE: The DVR Inspector is designed to function with the connections / settings described
in this manual. Please contact NETmc Marine Support team (see Section 5) before
attempting to connect any external equipment not described below.
Audio input:
Audio input to the DVR Inspector is either via the line in RCA sockets (e.g. from a diver comms
system) or via a dynamic microphone (see typical image below) plugged into the ¼” (6.35mm) mono
jack socket.
Frequency response: 80Hz – 12kHz
Impedance: 600 Ω
Sensitivity: -76dB @ 1kHz
¼“ (6.35mm) plug
NETmc Marine DVRi Manual rev. 5.3 May 2010 4 of 43
On the front panel of the recorder is found the main ON button, the receptacle (where fitted) for the
removable drive and a small LCD screen beside which there are 4 black buttons, these buttons are
for the control of the menus that are displayed on the screen. These screens are primarily displaying
status indicators and so, under normal circumstances, the operator need not concern themselves
with them.
Some newer models also have
microphone / headphone
2.2 DVRi Peli. Hardware Description and Connections
NOTE: The DVRi Peli is designed to function with the connections / settings described in this
manual. Please contact NETmc Marine Support team (see Section 5) before attempting to
connect any external equipment not described below.
NETmc Marine DVRi Manual rev. 5.3 May 2010 5 of 43
Audio input:
Audio input to the DVRi Peli is either via the line in RCA sockets (e.g. from a diver comms system)
or via a standard microphone (see typical image below) plugged into the ¼” (6.35mm) mono jack
socket.
Frequency response: 80Hz – 12kHz
Impedance: 600 Ω
Sensitivity: -76dB @ 1kHz
¼“ (6.35mm) plug
Please ensure that no cables etc have been left on the surface of the DVRi Peli before closing the
lid, as this could damage the monitor.
2.3 Installation of Inspector with removable drive
1. Install the DVRi in a 19” rack giving consideration to the height at which the unit is mounted
to facilitate the easy removal of the hard drive.
Note1: It is essential that sufficient space be allowed behind the recorder to allow the
power supply-cooling fan to function correctly.
Note2: If networking the DVRi, all network connections must be made and the network be
live before switching on the DVRi, otherwise no streaming video will be available.
NETmc Marine DVRi Manual rev. 5.3 May 2010 6 of 43
2. If the video signal is first being routed via a composite monitor, ensure the impedance switch
on the monitor is set to open, otherwise no picture will be seen on the DVRi screen.
3. Make all the necessary connections at the rear of the recorder, including power cable,
keyboard and mouse; the required connections will vary depending on the video signal being
input, display devices being used etc.
4. Switch on power supply at rear of recorder, position 1.
5. Insert a hard drive in to the receptacle at the front of the machine. Do this GENTLY.
Although the drives are ‘Hot Swappable’ we advise that drives are only inserted or removed
when unit is powered OFF.
6. Press the “power on” button on the front panel. The two LEDs on the front of the removable
drives should be on. The Green LED is a power indicator and the Red LED is a status
indicator for the fan, if the Red LED is on the fan is OK, if it is blinking then the fan is not
working correctly.
Note: This is not a “power off” switch.
2.4 To Power-down the DVR Inspector/ DVRi Peli
• Close all desktop applications
• Click START from the Windows Tool Bar
• Select SHUTDOWN
• With Shutdown selected, click OK
This will close Windows and switch off the PSU
DO NOT REMOVE MAINS CONNECTION BEFORE SHUTDOWN

3.2 LCD Screen Display (not applicable to DVRi Peli)
This display on the small LCD screen on the front panel of the DVR Inspector also updates as the
unit powers up.
First displayed is an initial screen containing NETmc Marine’s contact details:
As the operating system kicks in, and Windows comes alive, the display goes through the following
stages:
As soon as the unit is fully functioning, the 2
nd
line of the display shows ENC = and digits that are
incrementing.
NOTE: This is a useful indicator if you any problems occur with your DVR Inspector. If the 2
nd
line
is frozen or shows ENC = any other text, it suggests that the underlying encoder system has
become upset. Please note down the text and contact NETmc Marine Support as described in
Section 5 below.

3.4.1 Black Box Recording
Black box recording is an optional extra. This option allows a separate, continuous recording of the
whole operation, for example for health and safety purposes, independent of whether the video is
currently recording. This button will only be enabled if you have purchased the Black Box option.
The following images indicate whether the Black Box is enabled or not:
ENABLED DISABLED
Recording
If the Black Box option is enabled, clicking on this button will start recording. The button will now
look like this:
The presence of a green tick in the status bar is also necessary for Black Box recording. This
indicates that the housekeeping system is functioning, whereby old files are deleted to make way for
new ones, enabling continuous recording. If no green tick is present, the disk will eventually
become full and recording will stop.
Unless otherwise arranged, the Black Box will record to a separate 120 gigabyte hard disk drive
called the D: Drive. Depending on the quality settings chosen, the Black Box allows continuous
recording for between 33 hours (highest quality settings) and 213 hours (lowest quality settings.)
Black Box files are automatically saved under the time and date recorded and can be accessed
through Windows.

3.5 Set-up Page
After clicking the SETUP button you will see the following screen. Here you can configure the
recorder; setting the video format and compression rate, the length or size of the video files (PKTS)
and allocating the storage path and file names.
NOTE: Units with SDI input have a different set-up page (see Appendix xi)
The set-up settings of the DVRi can be changed, however the unit will have been shipped from the
factory configured with the optimal settings for your application– it is recommended that these be left
as shown above (settings for MPEG1) or at least a note is made of them to enable the unit to be
configured as it was when it left the factory.
NETmc Marine DVRi Manual rev. 5.3 May 2010 13 of 43
NETmc Marine DVRi Manual rev. 5.3 May 2010 14 of 43
A description of each parameter in the set-up screen is given below:
Application:
Enable keyboard Shortcuts This enables or disables the use of keyboard shortcuts.
See appendix (iii) for a list of short cuts.
Always on top Keeps the video recorder display on top of any other windows that
may be open.
Enable Preview Automatically starts the live video on start-up
Grey “SETUP” box this is for engineer configuration only
Device:
Enable Remote Access Allows network control
Format:
MPEG1 Select to record in MPEG1 format
MPEG2 * Select to record in MPEG2 DVD format.
MPG2HD* Select to record in MPEG2 high definition.
MPEG4 * Select to record in MPEG4.
*. These options are only available if there is a suitable encoder installed.
NOTE: The selection of the format does not just depend on the desired quality of the video;
consideration should also be given to how you will view the data at a later date. For instance should
you wish to view the data over the Internet then you may wish to use the lowest compression rate
available.
Source:
BNC – Click this if video is coming in via the BNC connector on the rear panel i.e. Composite
input.
Y/C – This option is no longer available
PAL – Click here if input video is in the European format PAL
NTSC – Click here if input video is in the American / Asian format
Quality:
This section allows the selection of bit rate – as specified in procedure or by experiment.
Video Storage Format:
MPEG only This setting will only record raw mpeg files
Pkt with embedded nav– With this option enabled, and a Navigation string being input to the
recorder, each MPEG file will be tagged with positioning data, this
then enables the video to be integrated in to a GIS system at a later
date.
Note: For structural inspections there is no benefit to ticking this box
as generally there is no acoustic positioning data available.
Although certain types of software (e.g. Coabis) require the use of
pkt to enable enhanced editing features.
Maximum Segment Size:
Each section of video recorded can be broken down into discreet video clips to aid reviewing and
managing the files. These sizes of each clip can be set by time or volume of data. Should you wish
to be able to download a file to a certain type of media e.g. a floppy disc, then you would select file
size as the controlling factor and set the size to fit your disc.
If on the other hand you wish to store the video by time then select that option and put in the
number of seconds you want the file to be.
The size of file chosen will depend very much on the project in hand, but should probably be no less
than 5 minutes; otherwise the number of files recorded may become excessive and difficult to
manage.

3.7 Replaying the data
3.7.1 Using Windows Media Player™
Replaying on the DVRi
• Go to the Desktop
• Click on “My computer”
• Click on the drive to which you are storing the video
• Open the video folder there
• Double click on the video file you wish to check; this
will automatically open up in Windows Media Player
However, we recommend preserving the DVRi for
recording only and replaying data through another
channel.
Replaying via a network, NAS device, or SATA drive (USB to Sata
adapter
• Go to the Desktop
• Click on “My computer”
• Click on the drive to which you are storing the video
• Open the video folder there
• Double click on the video file you wish to check; this will automatically open up in Windows
Media Player
NOTE: Using Windows Media Player it will only be possible to play one video segment at a time.
NOTE2: If files were recorded in MPEG2 format, then a codec will be required. This is available to
download from our website. See
www.netmcmarine.co.uk/file_downloads.htm - (Elecard is our
preferred codec for viewing MPEG2 files.) A symptom that a codec is required is a black screen -
with audio but no picture.
If the video was recorded to a removable drive you will need to insert the drive in to the USB caddie
and connect this to your PC. Once the storage unit is connected to the USB port of your PC, a new
drive will appear on your desktop. Follow the same options as above.
3.7.2 Using the NETmc Player
another way to view the video is with the NETmc Marine viewer –this can be downloaded from our
website - see
www.netmcmarine.co.uk/file_downloads.htm . Download Video Viewer and also
Elecard to view MPEG2 files.
To use the special player, click on
the “3HEAD PLAYER TOOL” shortcut. (This is called the 3 head player
as it can be used with our 3 channel
DVR PRO as well).
You now have access to a very powerful viewer
and editing software package which can play
multiple contiguous files and edit across them
using the “MARK IN” and “MARK OUT” buttons.
This edited video can then be saved as a new
file.
There is also the facility to take additional
“SNAPS” during review.

Appendix iv: COABIS Interfacing
This section explains how to configure the Coabis digital video interface for the NETmc Marine DVR
rface. First, you must connect and
o footage and still
d images.
To command a DVRi from a Coabis system you will need:
A PC to run Coabis
A network card in that PC
An IP address on your coabis machine in the same range as the DVRi
A cross-over network cable (or hub/switch and 2 cables) to link PC & DVRi
Once you have Coabis installed on your PC – connect its network cable to the DVRi – either via a
cross-over cable, or by using a network hub/switch.
Set the IP address of the Coabis box to be in the same range as the DVRi.
Typically, DVRi units will have an IP of 192.168.1.serialno (i.e. serial number 37 will be 192.168.1.37)
and a subnet mask of 255.255.255.0.
The coabis PC should have the same subnet and its IP address should start with 192.168.1.? – with ?
being anything which is not already in use on the network – and not the same as the DVRi.
If your Coabis PC is also part of a corporate IT network – you may need to get a second network card
installed – alternatively you can configure the DVRi to join the corporate network. Permission and

The Coabis PC is connected to the Overlay by means of a Null Modem Cable.
Configuring the Encoder
On the encoder, run the DVRi Setup shortcut. From the DVRi set-up screen, ensure the following are
set:
AddFileNo, AddSeqNo option MUST be checked.
Everything else MUST be unchecked.
The video output format and quality settings are at the discretion of the end-user.
The coabis PC and the DVRi must be able to view the storage location for the digital video.
Therefore, if the video being stored to the DVR is internal or caddie drive – these must be “shared” so
others can see them over the network.
This is done by using the windows explorer on the DVRi and simply ‘right-clicking’ the drive you wish
to share. Select “Sharing” – enable sharing and enter a share name of your choice.
When setting up paths to this location within Coabis, use the UNC naming convention – which is two
back-slashes then the IP address of the unit with the share then back-slash the share name. We
recommend the share name is “Coabis” e.g.
\\192.168.1.37\coabis

Coabis Setup
Firstly go to Baseline – Basics – Directories, and set DV-A, DV-G and DV-R as shown below.
NB: 192.168.1.xx should be replaced with the IP address of the DVRi.

Overlay Setup
NB: If Coabis fails to connect to the overlay, try changing the Port.

Appendix v: Recording to a networked Server / NAS
Sometimes, it may be more desirable to save digital video data to a central network available storage
facility – rather than storing the data locally on the DVRi (either on its internal disk or on its caddie
drive).
Examples of network storage can be
A NAS box
A server with storage attached or in built
Another PC on the network with a lot of storage
The setup procedure for this is:
On the network storage unit – create a shared directory where you want the video files to go.
This is typically named “Coabis”
It should contain the required 3 sub directories as defined in section v (typically “routine”, “anoms”
and “grabs”)
You then configure the Coabis PC to direct video and grabs to \\network_storage_IP\coabis
with the
appropriate subfolder.
e.g. – if the IP of the NAS box or server is 192.168.1.1, you would enter into Coabis:
\\192.168.1.1\coabis\anoms
\\192.168.1.1\coabis\routine
\\192.168.1.1\coabis\grabs
Permissions
The DVRi units ship with
User = Administrator
Pwd = (no password)
If the NAS or Server uses different credentials for its Administrator login, then there will be a problem
and no video files will be recorded. (You may get some .ssn files, but no .mpeg and no .pkt files)
To solve this either:
- change the Administrator password on the NAS / server to blank
- or, change the logon settings of the mediaNET despatcher on the DVRi (see next section)
It is vital that the DVRi has permission to write to the NAS box or server.

Appendix vii: Real time file duplication
If network connections are not reliable – or if a user wishes to save data to 2 different locations
simultaneously – it may be desirable to record video data to the local caddie drive on the DVRi – and
also to
another location on the network.
one between the DVRi and another storage device.
We can verify and confirm correct operation of these tools with our software and systems – currently,
the products we have tested and are happy with are:
Robocopy
If you use any other utility, we will not be able to support you – so take care in your selection if you do
not have IT support elsewhere.
Use of Robocopy:
You should download or be supplied a copy of Robocopy by our integrator.
Copy it to a directory on the DVRi (e.g. c:\robocopy)
Create a .cmd file and configure it to run in the “startup” folder of windows.
The contents of the .cmd file should be:

Appendix ix: Integrated Overlay configuration
Rackmount DVR Inspectors
DVRi units can now be shipped with optional integrated overlay / screenwriter.
The overlay is physically fitted inside the DVRi removing the need for a separate physical unit and
minimizing rack space required. But it is treated as a separate entity - with the connectors
presented externally – which allows the user to by-pass the overlay if required.
The DVRi overlay is a 2 data input system – and only 2 data inputs are possible at any one time e.g:
- Overlay Manager and NAV, or
- NAV and Inspection Data, or
- Inspection DATA and CP
- etc
Connections
Whichever data input system is used, in order to enable overlay – the input video signal should be
first routed to “Overlay In” – and then from ‘Overlay Out’ to the regular video input to the DVRi (using
the supplied BNC to BNC cable).
Latest DVR Versions
Older versions of DVRis

should be plugged into either of the overlay
data ports on the

Only 1 external overlay data input is offered – this is the only serial connector on
The video signal is also permanently routed via the overlay so there is no need for a BNC jumper
cable as described above.
Overlay Commands
The overlay characters are generated by either using the Overlay Manager software from the DVRi
screen – or by injecting serial commands into one of the overlay serial ports on the back of the DVRi.
Typically, this will be a cable to a Coabis, Scope or E-Inspect workstation on Serial 1 – while Serial 2
might be reserved for CP or other information.
The cable used should be a 9way fe m cable.
The wiring is as follows:
