Chapter 2 Installation Guide
2.1 Acquisition Check
When users open the package of the device, it is necessary to check items according to packing
list. Normally it should include the following items:
NDS3208 8 in 1 MPEG-2 Encoder
User‟s Manual
Analog Audio/Video Composite Input Cable
ASI Cable
Power Cord
If any item is missing or mismatching with the list above, please contact local dealer.
2.2 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 content of this chapter including:
Checking the possible device missing or damage during the transportation
Preparing relevant environment for installation
Installing Encoder
Connecting signal cables
Connecting communication port (if it is necessary)

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

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 50Hz. Please carefully check before running.
2.2.3 Grounding Requirement
All function modules‟ good grounding designs are 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 cable‟s 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.

2.2.4 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.
2.2.5 Device Grounding
Connecting the device‟s grounding rod to frame‟s grounding pole with copper wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel, and the power
switch, fuse, power supply socket is just beside ,whose order goes like this, power switch is on
the left ,power supply socket is on the right and the fuse is just between them.
Connecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC power.
Connecting Grounding Wire
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 NDS3208 8 in 1 MPEG-2 Encoder, user should
set the power switch to “OFF”.
2.4 Signal Cable Connection
The signal connections include the connection of input signal cable and the connection of
output signal cable. The details are as follows:

2.4.4 Unbalanced audio and CVBS video input connection
User can firstly find the CVBS input connector on the device according to the connector mark
described on the rear panel illustration, and then connect the analog CVBS video and
unbalanced audio cables (in the accessories). One end is connected to the signal source
equipment while the other end to the encoder‟s CVBS input port. The encoder‟s Analog
Composite Video input port and its connection are illustrated as follows:
