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.

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.
