Chapter 1 Product Outline
1.1 Outline
NDS3542D multi-input modulator is DEXIN’s all-in-one device which integrates
demodulation, trans-mux and modulation in one case to convert signals into RF
output. It is a 1-U case which supports 4 tuner inputs to receive signal from satellite,
cable or terrestrial. To meet customers’ various requirements, NDS3542D is also
equipped with 2 ASI input, and output with 2 groups separate ASI ports and 4 MPTS
UDP IP port. The output modulated signals are to be received by TVs, STB and etc.
The USB port is designed to record encoded video (TS) and save it in ts files in the
USB Keys or Hard Disks, and then the ts files can be playback through the USB port.
The four CAMs/CIs accompanied and BISS modules can descramble the programs
input from 4 Tuner inputs. Its pluggable structure design greatly facilitates the
change of modules (demodulator) as needed.
1.2 Features
Support 4 DVB-C/T/T2/S/S2 Tuner and 2 ASI input ports
Support accurate PCR adjusting
Support PSI/SI editing and inserting
PID Remapping
Excellent RF output performance index, MER≥42db
4*DVB-C RF out
2 separate ASI&IP (4*MPTS over UDP) mirror 4 RF output
4 CAM decrypt multiple programs from 4 Tuner input
Support BISS descrambling
Record encoded TS and playback TS files (*.ts) through USB port
Support LCD display and keyboard
Support Web management, Updates via web and USB

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:
NDS3542D Multi-input Modulator 1pcs
User’sManual 1pcs
RF/Loopout Cables 4 PCs
ASICable 1pcs
PowerCord 1pcs
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 modulator
Connecting signal cables
Connecting communication port (if it is necessary)

Power
Requiring device power, air-conditioning power and
lighting power are independent to each other. Device
power requires AC power 100-240V 50-60Hz. 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.
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.
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 NDS3542D Modulator, user should set the power
switch to “OFF”.
