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
manufacturer.
•Occasionally check the power connector and remove dirt or dust that may
have accumulated.
•Use only the mains cord that comes with your unit.
•Do not operate the unit or plug in the mains cord if it is broken, split, or
damaged in 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 proper grounded socket. Insufficient
grounding may cause electrocution.
•Always carefully disconnect all plugs by taking off the plug and strictly
forbitten to pull the cord in order to disconnect the unit . 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
•This unit contains parts that cannot be repaired by the user. Do not
disassemble or try to repair it as this will void all warranties. Please contact
the manufacturer if you experience any problems with your unit.
Water/humidity
•Do not keep the unit in a humid place or near water.
•Do not plug/unplug the unit with wet hands.
Fire
•Never place a candle or another source of fire on the unit as it may fall and
start a fire.
•If the mains cord or the power connector is damaged or destroyed, or if there
is a sudden loss of picture during operation, or if you notice a strange smell or
there is smoke, immediately switch the unit off, disconnect the mains cord and
contact the manufacturer’s technical support department.

Installation / Storage
•This unit contains high precision pieces of electronics. To ensure optimal
performance and avoid damage, do not store it in any location where it may
collect dirt, duct, lint, etc. Do not expose it to extreme heat or cold (e.g. in
direct sunlight, near a heater or in the car during the day). Place the unit in a
secure place to avoid falls.
•Before moving the unit, always unplug all cords first.
•When installing the unit, make sure that an outlet is within easy reach. In case
of malfunction, switch the unit off and unplug the power cord. When the unit
is not in use for a long period of time, make sure that the mains cord is
disconnected.
Connectivity
•Before connecting the unit to other electronic devices, always switch off and
unplug all devices.
Maintenance
•Do not spill liquids on the unit. Do not use any diluents or volatile liquid to
clean the unit. Instead, use a soft slightly damp cloth and allow the unit to dry
completely before using again.
Handling
•Do not poke your finger into the openings on your unit.
•Never put paper, metal parts or other objects into the openings of your unit. If
you suspect that there are foreign parts in your unit, switch it off and unplug
the mains cord. Contact the manufacturer’s technical support department.
•Do not step on or place heavy objects on top of the unit. To avoid hardware
damage, handle all buttons, connectors and switches gently.
2. INTRO
Congratulations on purchasing the DFL-100H. You now own a high quality,
semiprofessional DTV modulator. To get the most out of your purchase, please take
the time to read carefully through this manual.
3. INSTRUCTIONS
3.1 DESCRIPTION
The DFL-100H is a very powerful, all-in-one device, able to receive up to 2
independent HD sources and to convert them in 2 x DVB-T/C RF output channel. The
embedded web server of the DFL-100H 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 makes the DFL-100H the ideal solution to
distribute HD sources coming from e.g. a STB or DVD player to a CATV installation
using the DVB-T/C signals.

•Auto NIT & SDT Configuration
•Low power consumption
•MER value > 45dB
•Very clean RF spectrum
•PCR re-stamping
•Custom NIT & SDT
•Very friendly user interface
•Wall mountable
•Compact size
•5 year warranty
3.2.1 Auto-reset functions and watchdog
During the normal operation of the DFL-100H , 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 DFL-100H 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 DVB-T or DVB-C compliant
The user is able to software select the modulation standard, between DVB-T and
DVB-C, of the DFL-100H without the need of any firmware upgrade.

Status - Inputs 1.2.
In these fields, the user is able to see the status of each HD input e.g. if the H.264
encoder is running or if it is in idle state, its Service name, its Service ID, video/audio
PID and LCN number.
Outputs –Modulator
In these fields, the user is able to see the status of all the RF output of the device such
as modulator state, RF output frequencies and modulation settings.
System
This section provides general information of the device, like internal status of all
device’s modules, CPU temperature and fan state as well as error codes for
troubleshooting purposes.
