1. IMPORTANT SAFETY PRECAUTIONS INFORMATION

READ THE FOLLOWING WARNINGS

BEFORE YOU USE YOUR DEVICE

WARNING

The following safety precautions must be observed to prevent fire or electric shock
hazard. Safety precautions include but are not restricted to the following:

Power supply / Mains cord

 Operate the unit only within the voltage range defined as appropriate by the

any way.
 Do not place the mains cord next to heating devices. Do not pull it, place heavy objects
on it or damage it in any way. Keep it out of reach of children.
 Ensure that the device is plugged in a properly grounded socket. Insufficient grounding
may cause electrocution.
 Always carefully disconnect all plugs by pulling on the plug and not on the cord. Make
sure the unit's power switch is turned off before removing the cord from an outlet.
 Disconnect the mains cord when the unit is not in use for long periods of time or during
storms.
 Do not connect the unit to a multiple-outlet to avoid plug overheating.

Disassembling

2. INTRO

Congratulations on purchasing the HCL-804CT. You now own a high quality, professional
DTV headend. To get the most out of your purchase, please take the time to carefully read
through this manual.

3. INSTRUCTIONS

3.1 - DESCRIPTION

The HCL-804CT is a very powerful, all-in-one device, able to receive up to 8 independent
HDMI sources and convert them in 4 x DVB-T/C RF output channels while making Gbit IP
streaming simultaneously. It supports “pool” technology, meaning that the user is able to select
any program from any of the 8 inputs and assign it to any of the 4 RF + IP outputs providing
great flexibility.

The embedded web server of the HCL-804CT provides a very friendly user interface as well
as the ability of remote or local control of the device via Ethernet.

Its small size and its powerful features renders the HCL-804CT the ideal solution in cases went
we want to distribute HDMI sources coming e.g. from a STB or DVD player to a CATV
installation using the DVB-T/C and IP technology.

3.2 - FEATURES

 8 x independent HDMI inputs
 4 x RF output DVB-T/C (software selectable)
 Gbit IP streaming (up to 64 x SPTS / 4 x MPTS)

 “Pool” technology

 MER value > 40dB
 Very clean RF spectrum
 PCR re-stamping
 Very friendly user interface
 Wall or rack mountable
 Compact size
 5 year warranty

3.2.1 - Auto-reset functions and watchdog

During the normal operation of the HCL-804CT, the main CPU monitors all the internal parts
in order to ensure that the device works normally. In case of an internal error or module failure,
the HCL-804CT immediately initiates the recovery procedure by resetting the appropriate
module or the device. Finally, watchdog timers ensure that the device will be reset in case of
CPU failure.

3.2.2 - “Pool” technology

The HCL-804CT supports “pool” technology, meaning that the user is able to select any TV
or Radio program from any input and assign it to any of the 4 outputs providing great flexibility.

3.2.3 - DVB-T or DVB-C compliant

The user is able to software select the modulation standard, between DVB-T and DVB-C, of
the HCL-804CT without the need of any firmware upgrade.

3.2.4 - IP streaming

The HCL-804CT is able to make IP streaming of all programs coming from the 8 x HDMI
inputs simultaneously with the RF modulation using UDP or RTP protocol, multicast or
unicast.

The max. output bitrate can be up to 480 Mpbs in “IP only” mode.

3.2.5 - Smart cooling

The HCL-804CT uses “Smart Cooling” technology in which the fan increases/decreases its
speed according to temperature variation. In case the temperature is lower than 25oC the fan
stops working to expand its lifetime. In case of fan failure or over temperature (>65oC) the
device stops working to protect itself.
