CW-4956
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 in order to supply the external data
streams as soon as possible. The connection with 100
Mbit/s rate can be used until the transport streams fit
in this data rate, beyond this, change to gigabit data
rate. In the first tests simple switches can be used, but
we suggest using switches that are suitable for
managing IGMP messages as soon as possible.
The factory setting for the 64-Channel IPTV
Remultiplexer inpu
t is IP address 10.123.13.101, for
the output is IP address 10.123.13.102. When using
several devices, set different IP addresses as soon as
possible to avoid IP address conflict. Users find help in
descriptions
CW-Net.pdf
which can be downloaded from the 'Papers' page of
the web site. The basic parameters of the CW-4956
(IP Address, MAC Address, etc.) can be set in the Full
version of the SW-4956 software on the System
Configuration page.
Probably, transmitting the transport stream over
IP network holds surprises even for users having
good networki
ng knowledge. The most important
knowledge is summarised in the publication 'Transport
Stream Managing over IP' (TSMoIP.pdf).
Important note: The gigabit system of CableWorld
is a very advanced, high performance system, where
the
transport
streams
commands are transmitted in a common network;
decreasing your expenses and increasing the potential
of remote control. The transport streams and the
control commands are selected according to the Port
numbers. The user's job is, assigning the Port number
range to be used for transmitting the TS and
programming it in the device. The device control must
be performed outside the TS Port Interval. The device
control can be totally disabled by the transport streams
outside the TS Port Interval.
In
the
CableWorld's
transmission is performed by FPGA circuitry, so the
data rate is not limited by the performance of the
internal processors, and the gigabit data rate can be
utilized up to 100%.
4. PUTTING THE DEVICES IN OPERATION
After unpacking remove the protection foil from the
stainless steel cover of the device. Connect the device
to the specified mains voltage and switch on the power
switch. After a few seconds (max. 60 sec) the device is
ready to operation.
Programming the device and saving the settings is
required only when putting the device in operation first
or when modifying the settings.

5. TECHNICAL DATA
The technical data of the devices are published
in their data
sheets, which are available at the web
site www.cableworld.hu.
The novelty of the A CW-4956 is, that besides
the UTP cable, the optical cable connection is also
possible. When optical cable is used, remove the
protecti
ve plug from the SFP housing, then gently
slide the SFP module according to the required
transmission (distance and wavelength) in place. The
supply voltage of the module is +3.3 V, the maximum
current consumption is 300 mA. After connecting the
optical cable the device will prefer the optical
transmission and will switch over to the UTP input
only, if the communication is unsuccessful.
The consumption of the optical modules is high, so
if the optical input is not used, do not store the module
plugged in the SFP connector. After removing the
module, put back the protective plug.
Additional technical data:
The CW-4956 is equipped with loop-through ASI
inputs, but despite the plastic BNC house, the external
parts (shield) of both the input and output BNC
connectors are connected to the device frame. The
isolating transformer here is used only for balancing
the signal.
