USER'S GUIDE
Dear User!
As a heritage of the analog technology a number of
program sources are still supplying composite PAL or
NTSC video signals (video players, local studio cameras,
etc.). The encoder series of CableWorld transmit these
analog signals into cable or IP-based broadcasting
networks in MPEG-2 packed format.
1. MECHANICAL CONSTRUCTION
The MPEG-2 Encoders are built in standard
19"x1 HU instrument frame. They are delivered
along with the following accessories:
1. Power cord
1 ea.
2. Spare fuse T 1.25 A
(placed in the fuse holder mounting)
1 ea.
3. Crossover cable with RJ45 connectors 1 ea.
The power consumption of all types is very low
therefore no special cooling or ventilation is
needed.
2. ELECTRICAL CONSTRUCTION
The devices are equipped with own switching
mode power supply. The supply voltage of the
interface circuitry is +3.3 V, but the signal
processing circuitry works with supply voltages of
+1.2 V or +2.5 V. The real power consumption is
low, the unit is suitable for continuous operation.
The device circuitry comprises high complexity
FPGA circuits, which should be configured to the
given task by the user. The device can be
configured with the software, free available for
downloading from the www.cableworld.eu web site.
The devices and the software of CableWorld Ltd
form a system, where one program can be used for
many devices, and some devices need several
programs. The programs run in Windows XP or
Vista environment, but the open system of
CableWorld allows controlling the devices by
anyone, from any environment with his own
software via IP.
3. HARDWARE AND SOFTWARE SUPPORT
The software for programming the devices can
be downloaded from the ‘Software’ page of the
www.cableworld.eu web site. The downloaded
installer exe file installs the software in the
C:\Program Files\CableWorld directory. These items
of software can be simply removed with the
‘Uninstall’ function from the PC any time, so they
can be installed for preliminary test, too.
The user’s guide of the software and the
detailed user’s guide for the device can be found in
the ‘Help’ of the software. The ‘Help’ can be
downloaded in pdf format from the ‘Software’ page
separately, too.
Programming the MPEG-2 Encoder requires
installing the SW-4888 basic software and the SW-
4901 auxiliary software (only for the CW-498x IP-
output versions). For examining the output stream
we suggest installing the SW-4811B TS Analyzer
software, but other manufacturers’ software can be
used, as well. It is useful, if the printed form of the
software Help file is available, too. In our latest
guides the important steps are emphasized with
large letters and pictures, those interested in the
details are informed with small letter descriptions.
After installing the software, the device and the
PC can be interconnected with the attached
crossover cable in 100Base-T mode for studying.
But we suggest interconnecting the device and the
PC via switch with straight cable.
