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.

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)
3.2.1 Device’s Installation Flow Chart Illustrated as follows：

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.
3.3 Wire’s Connection

DHP400 Head-end Processor User Manual 8
3.3.1 Power cord connection
The power socket is located on the right of rear panel, and the power switch is on
the left of front panel. User can plug one end of the power cord to the socket and
insert the other end to AC power. When the device solely connects to protective
ground, it should adopt independent way, say, share the same ground with other
devices. When the device adopts united way, the grounding resistance should be
smaller than 1Ω.
Caution: Before connecting power cord to DHP400 head-end proccesor, user
should set the power switch to “OFF”.
3.3.2 Signal and NMS Cable Connection
The signal connections include the connection of input signal cable and the
connection of output signal cable.

Chapter 4 Web NMS Management
This device does not support the LCD operation, and the modification can only be
operated under Web NMS.
4.1 Login
The factory default IP address is 192.168.000.136 and users can connect the
device and web NMS through this IP address.
Connect the PC (Personal Computer) and the device with a net cable, and use ping
command to confirm they are on the same network segment. For instance, the PC
IP address is 192.168.000.252, we then change the device IP to 192.168.000.xxx
(xxx can be 0 to 255 except 252 to avoid IP conflict).
Launch the web browser an input the device IP address in the browser’s address
bar and press Enter.
It will display the Login interface as Figure-1. Input the Username and Password
(Both the default Username and Password are “admin”. And then click “Sign In” to
start the device setting.
