P r o d u c t O v e r v i ew
DiviCatch RF refers to all RF-enabled DiviCatch devices. This manual covers
DiviCatch RF-C and DiviCatch RF-T/H devices.
ENENSYS' DiviCatch RF was designed to catch a live modulated signal or an
MPEG2 Transport Stream from any application and turn it into a USB2.0 link to be
received by a laptop equipped. DiviCatch RF is equipped with an RF tuner and a
demodulator for signal analysis. DiviCatch RF also integrates an ASI input to allow
for MPEG2 TS monitoring and analysis.
When connected to an MPEG2 source, DiviCatch is able to record it on the hard
drive of a PC (provided that source is valid), and also to monitor displayed services.
DiviCatch is self-powered. It gets its power from USB bus, thus does not require
any external power supply.

Any PC equipped with USB2.0 interface and an application running on Windows
OS (Windows 2000 or Windows XP), at least PIII @ 300MHz supported by 256 MB
RAM.
Depending on bit rates to process and analyze, higher configurations may be
required, especially with DiviCatch RF devices. The more analysis modules are
started, the more memory and CPU are used: Always check CPU and memory
usage. Recommended configuration for all types of streams is CPU @ 1.66GHz and
0,99GB RAM.
Depending on bit rates to record, hard drive speed is a determinant factor. For
input bit rates lower than 80Mbps, a 5400 RPM disk is enough. For higher
throughputs, it is recommended to mount a faster disk (7200 RPM or above, with
eventually Serial ATA or SCSI interface).
DirectX 9.0 (or higher) library is required so that audio/video services can be
displayed in the Analysis window. DirectX 9.0 is provided with Windows XP. It can
also be downloaded and installed from Windows' website.

Install DiviCatch software from Companion CD. Execute the setup file from the folder ENENSYS
Software\DiviCatch\GUI and follow instructions.
NOTE: It is important that no DiviSeries device is attached to the computer during the installation.
P l u g D i v i C a t c h f o r t h e f i r s t t im e (Windows XP or Windows 2000 only)
– Once the installation process has completed, connect the DiviCatch RF device to a USB2.0 port on the
computer using the USB cable shipped with the DiviCatch RF device.
– Windows system finds new hardware and launches a new hardware wizard automatic driver installation
wizard. Choose “No, not this time”, and click Next. Then choose “Install the software automatically”, and
click Next. Continue until installation is complete.
– Wait for a couple of seconds (no need to unplug/replug); Windows system will re-enumerate the
device and will ask for a second driver installation. Same as previous step and continue until
install is complete.
– When driver installation is done, DiviCatch RF led gets red. Then launch the application
(DiviCatch RF led gets orange).
V e r y i n t e r e s t i n g r e m a r k s . . .
• Driver installation is only valid for the very USB2.0 port the DiviCatch RF device is connected to. If
DiviCatch RF is connected to any other USB2.0 port, Windows system will start another device
enumeration and behave as if a new USB device was detected. Companion CD will not be required and
Windows re-enumeration wizard will self complete. In order to be able to use the DiviCatch RF device
from any USB2.0 port, installation must be done for each USB2.0 port.
• DiviCatch application is not workable when no DiviCatch device is connected to the USB2.0 port of the PC.
• If you have purchased the GPS option, check the “GPS drivers” box at installation time without the GPS
receiver being connected to the PC.
•Meaning of LED colors on device:
OFF: no driver installed, happens when DiviCatch RF is plugged for the 1st time.
Red: Driver installed and device is recognized
Orange: DiviCatch application is launched (SW and device are connected), DiviCatch is ready to run
Green: receiving a stream (slow blink=188, fast blink=204 bytes/packet TS)

is saved into the profile, allowing you to have your own frequencies on different
stations.
D i v i C a t c h R F - T / H – S i g n a l t u n i n g
Note: The portable antenna provided with the product is intended as a “starter”
antenna. Depending on environmental conditions and network topology, this
antenna may not be powerful enough to tune to all signals. If this is the case, it is
recommended that a more powerful antenna (offering gain) is used.
The DiviCatch RF-T/H must lock the DVB-T or DVB-H input signal. The Tuning
section in the RF-T/H panel lets you specify all the necessary information to tune
the device to the desired signal.
● Channel bandwidth: Specify the channel bandwidth
occupied by the multiplex you would like to connect
to. Choose between 5, 6, 7 or 8 (expressed in MHz).

Analysis modes: DVB and ATSC
Two modes for interpreting MPEG2-TS signalling are available: DVB and ATSC. DVB
Mode is used for interpreting PSI/SI signalling, and ATSC mode is used for interpreting
PSIP/SI signalling. Switching between modes is performed through the TS Mode drop-
down list
General use
All tabs can be detached for a more comfortable viewing through a drag-and-drop of
the tab outside of the TS analysis section. This viewing is especially useful to real-
time monitor a specific table at the same time as a different table or RF parameter.
All tabs can be detached and become independent windows. Close a detached tab to
reintegrate it to the list of tabs inside the TS Analysis section.
“Programs” tab displays all the services
contained within the stream. In this
case, 3 programs are detected
(“Cambodia”, “Kenya” and “USA”
