CHAPTER 1
Introduction
General Description
The Thor H-AC3-CMOD-QAM-LL encoder & modulator is a portable part of the popular CMOD series of digital
HDTV encoder modulator systems formally known as VQAM. Like all CMOD systems, this platform is available
in three versions for use with over 95% of the world’s broadband TV systems. Advances in technology have
reduced component size to the scale that Thor can now integrate every system and component necessary for a
digital HDTV headend into a single handheld unit. CMOD systems are combination devices that bundle a real
time MPEG hardware encoder, DTV transport stream generator, and agile RF frequency modulator in a single
enclosure. Any HDMI live video source can now be converted to an open TV channel for insertion and
distribution over cable & antenna TV coax systems. The generated program can be viewed natively on any
television set with its built in tuner.

Safety Instruction and Installation
Safety Instructions
WARNING:To prevent fire or electrical shock, do not expose the device to rain or
moisture.
The encoder modulator is powered with a voltage of 12VDC. Please do not use
with any other power source or it can cause serious harm to the unit and will void
the warranty provided by Thor Fiber.
Therefore: Follow these simple rules
Do not replace power supply with a voltage greater than 12VDC.
Do not connect the device to the power unit if the power cord is damaged.
Do not plug the device into anything until it has been correctly installed
Do not cut the cord.
Avoid placing thedevice next to central heating components and in areas of high
humidity.
Do not cover the devicewith elements that obstruct the ventilation slots.
If the encoder modulator has been kept in cold conditions for a long time, keep it in a warm
room for a minimum of 2 hours before plugging it into a socket.
Mount the device in a vertical position with the connectors located on the top side.
If replacement parts are required, be sure the service technician has used replacement parts
specified by Thor. Unauthorized substitutes may result in fire, electric shock or other hazards.
Safety check- Upon completion of any service or repairs to this device, ask the service
technician to perform safety checks to determine that the device is in proper condition.

Installation
Follow these simple steps to avoid damaging the unit
Do not open the unit. Do not connect the unit to the powersupply before or during
assembly.Connect the unit as shown below
5 Steps for Success
1. Mount and tighten the screws and plugs
to securethe unit to the wall. Leave 10
cm of free space around from each unit.
2. Connect the signal input in the
respective connectors. The
signal source can be from a
surveillance monitor, DVD,
set-top box, CCTV and etc.
3. Optionally, connect the
loop-through RF inputcoaxial
cable.
4. Connect cable to RF output to
STB/TV.
5. Powersupply connection: a)
Connect the earth cable; b)
Connect the power plug to

the unit mains connector; c)
Connect the power plug to
the socket.
Cascade Installation
H-AC3-CMOD-QM-LL unit has 1 TV
signal to RFoutput encoded as
DVB-C DigitalTV signal.
Several units can be
cascaded in order to increase the
capacity. The maximum capacityof
a series of N units is 1xN.You can
stack as many inputs as you like
and use the loop out feature or for
larger installations you can also
use a combiner.
