Chapter 1 Product Outline
1.1 Outline
NDS3107Cmultiplexer is an enhanced TS re-multiplexer for digital TV broadcasting
head-end system. It can multiplex up to 8 ASI and 512 IP input and output TS through 2
groups of separate ASI output port and two GE port for two separate IP outputs. The
multiplexer has all the functions of normal TS multiplexer, including programs
multiplexing, PID re-mapping etc. Also the multiplexer can insert EPG (Electronic Program
Guide), and data casting information into each output stream. In conclusion, its high
integration and cost effective design make this device widely used in the CATV
Broadcasting system.

Chapter 2 Installation Guide
2.1 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:
NDS3107C Multiplexer
User’s Manual
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 includes:
Checking the possible device missing or damage during the transportation
Preparing relevant environment for installation
Installing multiplexer
Connecting signal cables
Connecting communication port (if it is necessary)
2.2.1 Device’s Installation Flow Chart Illustrated as following：
2.2.2 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

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 50Hz. Please carefully check before running.
2.2.3 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.
ASI 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
NDS3107C Multiplexer User Manual

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 is solely connected 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 NDS3107C multiplexer, 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:
2.4.1 ASI In and ASI out connection:
ASI Input Connection
User can find ASI input port on the device according to connector mark described in the rear
panel illustration, and then connect the ASI cable (in the accessories). One end is connected to
the Multiplexer’s ASI input port, while the other end is connected to Encoder’s ASI output port
or ASI output port of other equipment.
ASI Output Connection
NDS3107C Multiplexer User Manual
User can find ASI output port on the device according to connector mark described in the rear
panel illustration, and then connect the ASI cable (in the accessories); one end is connected to the
Multiplexer’s ASI output port and the other end to the Modulator’s ASI input port or ASI input
of other equipment. Multiplexer’s ASI cable illustrated as follows:

Chapter 3 Operation
NDS3107C multiplexer’s front panel is user operation interface. The detailed operations go as
follows:
Keyboard Function Description:
MENU: Canceling presently entered value, resuming previous setting; Return to previous menu.
ENTER: Activating the parameters which need modifications, or confirming the change after
modification.
LEFT/RIGHT: To choose and set the parameters.
UP/DOWN: Modifying activated parameter or paging up/down when parameter is inactivated.
LOCK: Locking the screen / canceling the lock state. After pressing lock key, the system will
question the users to save present setting or not. If not, the LCD will display the current
configuration state.
At the page of 5.2 “Load default CFG”, user can firstly press “ENTER” key, consequently
system resumes factory parameter setting.
