4Introduction
The domo IP Hardware Decoder is a professional digital video decoder
designed to receive multicast audio/video streams from Ethernet networks
and output decoded video in composite and S-Video formats, as well as
stereo audio. The IP decoder is designed to be used with domo
NETSTREAM and other domo streaming video products such as the CRX
Central Receiver.
The domo IP Hardware Decoder (NETIPHW2) is a 19’’ Rack product that
incorporates two video decoders into a single chassis. The unit is designed
to receive streaming video services from Ethernet networks and decode
these back to video for connection to monitoring equipment in control room
facilities. The IP Hardware Decoder incorporates low delay decoding
technology as well as optional AES decryption for security.
The NETIPHW2 decoder has two physical Decoder cards fitted. At first
release each decoder supports one channel of decoding. However, in the
future, as an upgrade, it will be possible for each Decoder card to decode
two channels of video. This will enable one NETIPHW2 to decode and
output up to 4 Video / Audio services.
The IP Hardware decoder complements the domo SOLO4 and SOLO2
product range, which enable the user to build wireless digital microwave
video systems. The standard domo SOLO4 and SOLO2
Encoder/Transmitter and Receiver/Decoder products have been designed
to provide rugged point-to-point links for high quality full frame rate video,
and audio, even in non line of sight and urban environments.

5Warranty and Support
5.1 Warranty Cover
domo offers a 12 month standard product warranty. During this period,
should the customer encounter a fault with the equipment we recommend
the following course of action:
•Check the support section of the website for information on that product and
any software/firmware upgrades. If fault persists;
•Call our support line and report the fault. If fault persists and you are
informed to return the product please obtain an RMA number from the domo
support department, and ship the equipment with the RMA number
displayed and a description of the fault. Please email the support section
the airway bill/consignment number for tracking purposes.
•If you have extended warranty provisions then domo will send an immediate
advance replacement to you. Under most circumstances this must be
returned once the fault item is repaired.
Depending on the nature of the fault domo endeavour to repair the
equipment and return it to the customer within 14 days of the item arriving at
our workshops.
Obviously it is impossible to cater for all types of faults and to manage 100%
replacement part availability, and delays are sometimes inevitable. This is
why domo recommend that its customers take out an extended warranty
(which includes advanced replacement of faulty items), and/or hold a basic
level of spare parts, which can be held by domo on the customer’s behalf.
Please contact domo for details of packages that can be tailored to meet
your individual needs, whether they are service availability, technical
training, local geographic support or dedicated spares holdings.

7.5 Installation Notes
The domo IP Hardware Decoder is a professional digital video decoder
designed to receive multicast audio/video streams from Ethernet networks
and output decoded video in composite and S-Video formats, as well as
stereo audio. The IP decoder is designed to be used with domo
NETSTREAM and other domo streaming video products such as the IP
Insertion Node and CRX Central Receiver. The NET IP Hardware decoder
is optionally equipped with two channels allowing it to decode two video
services simultaneously.
The domo SOLO2/SOLO4 IP Decoder is designed to be mounted in an
equipment rack or shelter and must not be exposed to the elements. The
receiver is not splash resistant, nor waterproof, so it should not be exposed
to moisture.
The IP Decoder is self-cooling; however it should be mounted in a ventilated
environment. Forced air cooling is not required. Adequate clearance on
either side the receiver (5cm) should be allowed for ventilation. In a 19inch
rack mounted environment domo recommends leaving 1U clearance above
and below the NETIPHW2 unit to ensure the unit does not overheat.
7.6 Network Requirements
The IP Hardware decoder should be connected to an Ethernet network with
the following characteristics.
Capacity
The network should have sufficient capacity to support the streaming of
video services.
Each domo video service occupies between 600kb/s and 4.8MB/s
depending on mode. Typical occupation is 2.4Mb/s. Therefore the network
must have sufficient capacity to support these services and also any other
data on the network.
Protocols
The network should support multicast UDP streaming protocols. Any
firewalls or routers should be programmed to allow multicasts through.
Multicasting on General Purpose Networks and WANs
Streaming on Local Area Networks does not usually present problems,
especially if the number of streams is proportioned to the network capacity,
and only layer 1 switches, and/or a single layer 2/3 switch are in use.
However, when multicasting on large networks with multiple streamers and
routers, care should be taken to avoid re-multicasting packets and creating a
sort of feedback loop where the all the network capacity is instantly used up.
By choosing the right TTL value for multicast packets and setting up routers
correctly, multicasting on larger LANs and WANs is possible.
Contact your IT department or the domo technical support for more details
on these subjects.

7.7 Initial IP Setup
This step is only required if the IP address of the unit is not known. This
procedure allows the user to give a temporary IP address to the Ethernet
port marked Main. This port can then be used to access the unit’s browser
interface and do a complete setup.
1) Connect the Ethernet port marked Main to the same network as the PC
used as controller. Alternatively, connect the PC directly to the port. The
IP decoder Ethernet ports feature MDI/MDIX automatic cable cross-
over, supported by most modern PC’s. This makes it unnecessary to
use a crossover Ethernet cable in most cases.
2) Connect a domo serial port control cable to the port marked RS232
Control. Connect the other end to the control PC.
3) On the PC, start a terminal program such as TeraTerm. Set the serial
port parameters as follows:
Baud Rate: 9600
Data: 8 bit
Parity: None
Stop bit: 1
Flow Control: None
4) Power on the system as described in the next section. If the terminal is
setup correctly, boot messages will be printed on the terminal window.
Wait until the boot procedure is complete, and messages are no longer
printed.
5) About one minute after the unit has booted, it will print the following:
“INIT: no more processes left in this runlevel”
6) At this point, start pressing the Enter button on the PC keyboard, until
the following message is printed: “New IP address? [type Yes]”
7) Type Yes, ensuring that the ‘Y’ is uppercase, and ‘es’ is lowercase.
Press Enter.
8) The following message will be printed: “Please enter new IP address,
then press Enter”. Enter a valid IP address and press Enter.
9) If the address is accepted, the message “New IP address has been
set” will be printed. Otherwise an error message will be printed. The
netmask is automatically set to 255.255.255.0.
10) The unit can now be accessed via a web browser running on the control
PC (assuming the PC is on the same subnet) by using the address that
has just been entered.
The IP address that has just been set is temporary, and will be lost when the unit
is powered off. To make any permanent settings, use the browser interface.

17
7.8 Powering on the System
All external connection to the IP Hardware Decoder products should be
made, as described in the previous sections, before proceeding to power on
the system.
On powering the IP Hardware Decoder, the system will boot in approx. 45
seconds, although a blue screen will be visible on the video outputs within a
few seconds of applying power.
The LED’s on the unit’s front panel show the progress of the boot sequence.
There are two LED’s for each decoder card fitted in the unit.
Refer to section 7.3 for meaning of LED’s.

18
7.9 Using the Browser Controller
Each channel within the IP Hardware Decoder is controlled from a standard
web browser running on the user’s PC or laptop. In order to access the IP
Decoder’s browser interface, the first step is to make sure the PC or laptop
is on the same subnet as the IP Decoder.
The default IP address for each IP Decoder card is set up at the factory
according to customer’s system requirements. Details of the addresses are
included in the documentation.
The following connection example assumes the IP address is 192.168.2.40.
To connect to this port, the user’s computer should be set to an address on
the same subnet, for example 192.168.2.1, with a mask value of
255.255.255.0. After setting these values, the connection can be tested by
sending a ping to the IP Decoder from the user’s computer. If the ping is
successful, connection via the browser can be attempted.
In the browser window, type the following in the URL bar: 192.168.2.40. The
controller’s main page should appear as shown below. When a link is
clicked, the user will be asked to login.
The username is admin, the password is vegemite.
If the IP Insertion Node and IP Decoder settings are left to their defaults, it
should now be possible to play a stream. Select the View Streams link in the
controller, and a list of available streams should appear.

19
7.10 Playing a Stream
Clicking on the View Stream link on the main page will show the Stream List.
The actual view depends on how many streams are visible on the network.
The image below shows three available streams.

20
To play a stream, the first step is to scan the required multicast to see how
many services it carries. Click on the Scan button, and within two or three
seconds a list of available services will appear.
If the streamer has RS232 link capabilities (like the domo IP Insertion Node or Central Receiver) the link
between the streamer and the IP Decoder will be automatically established at this point.
