Chapter 1. Introduction
1.1 Product overview
Ref. 554501 and Ref. 554601 are respectively a wall mount and a rack, DVB-T
modulation integrated device to convert HD A/V signals to DVB-T RF out in
the frequency range of 30~960 MHz. It has equipped with 2 encoder slot, and
1 RF input. The signals source could be from satellite receivers, closed-circuit
television cameras, Blue-ray players, and antenna etc. its output signal is to be
received by a DVB-T standard TV, DVB-T STB. The device can be used in public
place such as metro, market hall, theatre, hotels, resorts, etc for advertising. It
also can be used for monitoring, training and educating in company, schools,
campuses, hospital…be sides that it’s a good choice for bars to oer HD sports
channels, for VIP entertainment channels, and more.

2.2 Installation precautions
This section to explain the cautions the users must have to avoid any injures
when using or installing the product. For this reason, please read all details here
before installing or using the product.
General Precautions
Must be operated and maintained free of dust or dirty.
The cover should be securely fastened, do not open the cover of the products
with the power on.
After use, securely stow away all loose cables, external antenna, and others.
Power precautions
When you connect the power source, make sure it will not cause any overload.
Avoid operating on a wet oor in the open. Make sure the extension cable is
in good condition.
Make sure the power switch is o before you start to install the device.
Grounding Requirement
All function modules’ good grounding is the basis of reliability and stability of
devices. Also, they are the most important guarantee of lightning arresting and
interference rejection. Therefore, the system must follow this rule.
Grounding conductor must be a copper conductor in order to reduce high
frequency impedance, and the grounding wire must be as thick and short as
possible.
Users should make sure the both ends of grounding wire are electric
conducter and antirust.
It is prohibited to use any other device as part of grounding electric circuit.
The area of the conduction between grounding wire and device’s frame
should be no less than 25mm2

In communications, guard intervals are used to ensure that distinct
transmissions do not interfere with one another. These transmissions may
belong to dierent users (as in TDMA) or same user (as in OFDM).
The purpose of the guard interval is to introduce immunity to propagation
delays, echoes and reections, to which digital data is normally very sensitive.

Electronic and Mechanical criteria which have been published by Televés. To
prevent potential hazard, please strictly follow the operation conditions.
Prevention Measure
Installing the device at the place in which environment temperature between
0 to 45 °C
Making sure good ventilation for the heat-sink on the rear panel and other
heat-sink bores if necessary
Checking the input AC within the power supply working range and the
connection is correct before switching on device
Checking the RF output level varies within tolerant range if it is necessary
Checking all signal cables have been properly connected
Frequently switching on/o device is prohibited; the interval between every
switching on/o must greater than 10 seconds.
Conditions need to unplug power cord
Power cord or socket damaged.
Any liquid owed into device.
Any stu causes circuit short
Device in damp environment
Device was suered from physical damage
Longtime idle.
After switching on and restoring to factory setting, device still cannot work
properly.

In this menu is possible to edit the Transport Stream ID, Original Network ID (each unit has to have a dierent TSID and ONID), assign a Network name (the same in
all units of the same network) and more. After each change is necessary to press Update NIT.
By pressing “Add” you will have access to the menu of the next images:
7.3.2 NIT, Hierarchy and LCN Conguration
