Chapter 1 Product Overview

1.1 Outline

DHP400 DTV head-end processor is the new generation of intelligent headend

processing equipment. This 1-U case comes with 6 independent module slots. Each

module can be configured individually based on the applications including

encoding, decoding, trans-coding, multiplexing, descrambling and modulating

processing and the combination of all these functions. It supports multiple input

and output interfaces and signal formats. With its powerful performance and low

cost, DHP400 is especially adequate for the new generation CATV system.

1.2 Features

Support Web management, Updates via web

Support flexible combination of different type of modules

Support up to 6 modules

Redundancy power supply (optional)

Support 1 ASI output (MPTS2)

Support 2 GE output, 512 SPTS (UDP, RTSP/RTP) output from GE1, 8 MPTS

Chapter 3 Installation Guide

3.1 Acquisition Check

When user opens the package of the device, it is necessary to check items

according to packing list. Normally it should include the following items:

DHP400 Head-end processor

User’s Manual

Power Cord

If any item is missing or mismatching with the list above, please contact local

dealer.

3.2 Installation Preparation

When users install device, please follow the below steps. The details of

installation will be described at the rest part of this chapter. Users can also refer

rear panel chart during the installation.

The main steps of the installation include:

Checking the possible device missing or damage during the transportation

Preparing relevant environment for installation

Installing DHP400 head-end processor

Connecting signal cables

Connecting communication port (if it is necessary)

3.2.2 Environment Requirement

Item Requirement

Machine Hall Space

When user installs machine frame array in one machine hall, the

distance between 2 rows of machine frames should be 1.2~1.5m and

the distance against wall should be no less than 0.8m.

Machine Hall Floor

Electric Isolation, Dust Free

Volume resistivity of ground anti-static material: 1X107~1X1010,

Grounding current limiting resistance: 1M (Floor bearing should be

greater than 450Kg/㎡)

Environment

Temperature

5~40℃(sustainable ), 0~45℃(short time)

installing air-conditioning is recommended

Relative Humidity 20%~80% sustainable 10%~90% short time

Pressure 86~105KPa

Door & Window

Installing rubber strip for sealing door-gaps and dual level glasses

for window

Wall It can be covered with wallpaper, or brightness less paint.

Fire Protection Fire alarm system and extinguisher

Power

Requiring device power, air-conditioning power and lighting power

are independent to each other. Device power requires AC power

220V ±10% 50/60Hz or 110V ±10% 50/60Hz. Please carefully

check before running.

3.2.3 Grounding Requirement

DHP400 Head-end Processor User Manual 7

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.

Coaxial cables’ outer conductor and isolation layer should keep proper

electric conducting with the metal housing of device.

Grounding conductor must adopt 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 2 ends of grounding wire well electric conducted

and be 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.

3.2.4 Frame Grounding

All the machine frames should be connected with protective copper strip. The

grounding wire should be as short as possible and avoid circling. The area of the

conduction between grounding wire and grounding strip should be no less than

25mm2.

3.2.5 Device Grounding

Connecting the device’s grounding rod to frame’s grounding pole with copper

wire.
