parameters are incorrect. To prevent<br />
a total failure of the compression sequence<br />
the encoder attempts an automatic<br />
reset. In actual fact, this is by<br />
far the easiest and frequently most efficient<br />
trouble shooting method available.<br />
After all, who hasn’t been asked by<br />
support staff “Have you tried turning it<br />
OFF and ON again?“ Come to think of it,<br />
why don’t all electronic devices behave<br />
like that?<br />
LINK: This LED indicates that a network<br />
cable is connected to the IP output.<br />
ACT: Each outgoing data packet<br />
prompts this LED to flash, just like with<br />
network switches.<br />
PWR: This LED becomes active as<br />
soon as the device is switched on and<br />
powered.<br />
FIBER: As soon as a fibre-optic cable<br />
is attached to the device this status<br />
LED lights up. The FIBER interface is<br />
available as an option and our test encoder<br />
was not equipped with one.<br />
The 10 LEDs do a tremendous job in<br />
always keeping you informed about the<br />
current status of the encoder. A short<br />
glimpse is all you need to find out if an<br />
error has occurred. We cannot praise<br />
this feature highly enough, because we<br />
SW-4901<br />
3. The SW-4901 software is a generic application<br />
for CableWorld devices. It can be<br />
used to configure every networking aspect<br />
of the CW-4412, including the IP streaming<br />
options. The SW-4901 application is very<br />
structured and the first tab will simply allow<br />
the user to configure the correct IP address<br />
to establish the communication link to the<br />
device. The Query button will then test if<br />
such connection has been established and<br />
lists a sum-up of the device. If you don’t<br />
remember what the correct IP address is,<br />
don’t be ashamed – it happens to all of<br />
us. CableWorld included a neat Search<br />
function, which will detect the device in the<br />
network.<br />
4. The second tab allows setting up the<br />
network: which ports are to be used for<br />
management and streaming and, of course,<br />
you can set the desired IP address of the<br />
CW-4412.<br />
5. The IP Receiver Platform tab is of no use<br />
for the CW-4412 and can be ignored for this<br />
device. It allows setting up incoming IP<br />
Transport Streams.<br />
6. It is the TS Sender Platform tab, which<br />
has to be configured, in case IP output<br />
is desired on the CW-4412. Because the<br />
CW-4412 has two independent encoders,<br />
the two upper groups, Transport Stream<br />
Sender 1 and 2 are to be used. Configuration<br />
is extremely self-explanatory, as all<br />
required fields are presented with corresponding<br />
names. If you want quick results,<br />
just hit the Send TS button, as all preestablished<br />
values are perfectly reasonable.<br />
You may want to change from “Send<br />
TS to Multicast” to “Send TS to IP”, in case<br />
Unicast is needed.<br />
7. The Schematic Diagram tab shows a picture<br />
explaining the common setup and the<br />
last two tabs for Special Settings and the<br />
SW-4800 Controller are best left for Cable-<br />
World <strong>eng</strong>ineers, in case there is a problem<br />
with the networking module.<br />
know that in most cases technicians<br />
have no end of other tasks to take care<br />
of, so they’ll appreciate that there’s no<br />
need to dig into several layers of status<br />
menus to see what’s going on. A quick<br />
look must do. And with the CW-4412 it<br />
actually does.<br />
The only way to operate and control<br />
the CW-4412 is from a PC, which is why<br />
we started out with visiting the manufacturer’s<br />
website at http://www.cableworld.eu<br />
to download the required software.<br />
Some may wonder why essential<br />
software is not provided on CD or DVD<br />
any longer, but these days manufacturers<br />
can reasonably assume that buyers<br />
of their products have Internet access,<br />
and this way the latest software release<br />
can be made available at any point in<br />
time. If our opinion is anything to go by,<br />
3<br />
4<br />
that’s the only way to go in this day and<br />
age. But we digress…<br />
In our case it was not even necessary<br />
to download new software, since the<br />
test unit came with the latest firmware<br />
release which cannot only be controlled<br />
with specially developed PC software<br />
but also through the newly integrated<br />
web interface, which can be accessed<br />
from any standard web browser. We<br />
tried out Internet Explorer, Firefox and<br />
Chrome and found no fault with any<br />
of them. All can be used to set up and<br />
control the CW-4412 as required.<br />
There’s only one little downer that we<br />
should not keep secret: Current smartphones<br />
and tablets cannot be used<br />
to control the CW-4412 because Java<br />
Runtime – which would be essential for<br />
that – is lacking. In addition, the imple-<br />
