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 25mm

- Guard interval

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.

Chapter 6. Troubleshooting

Televés’ ISO9001 quality assurance system has been approved by CQC organization. For guarantee the products’ quality, reliability and stability. All Televés products have been passed the testing and inspection before ship out factory. The testing and inspection scheme already covers all the Optical, 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. Maintenance needed

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

In this menu is possible to edit the LCN of each program (in order to be listed correctly the Hierachy Information must be set to “a-1, a-2 or a-4”, the same on each unit of the same network). The LCN can be set by any order, in the image above it can be observed that the unit 2 will have program 1, 3 and 4 and unit 1 will have program 2.

List aspect with LCN List aspect without LCN

On these two images it can be seen the two possible ways to list the programs:

• With LCN – the programs are listed in order according with the LCN con guration set above.

• Without LCN – the programs list will depend on the TV/STB and it can be based on:

- Alphabetic order

- Mux frequency

- First the HD programs, listed based on the mux frequency

- Then the SD programs, listed based on the mux frequency
