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.
