Chapter 1 - Introduction

1.1 Product Overview

NDS3524C encoder modulator is DEXIN’s a all-in-one device integrating MPEG2 encoding and
modulating to convert audio/video signals into DVB-C/T/ATSC/ISDB-T RF out. It support 4 HDMI
inputs, and its pay-as-you-grow modular design (maximum support 8 HDMI inputs) and flexible
configuration are making it extremely scalable, very reliable with high performance. The signals
source could be from STB, satellite receiver, closed-circuit television cameras and antenna etc. Its
output signal is to be received by TVs or STBs etc.
The signal source could vary from satellite receivers, closed-circuit television cameras, Blu-ray
players, and antenna (off air). Its output signals are to be received by TVs, STB, etc. with the
correlated standard the unit is set to encode with (ATSC, DVB-T, DVB-C).
The 4-ADHD units are widely used everywhere such as the mall, market hall, theatre, hotels,
restaurants, stadiums, race tracks, ampitheatres and etc. for advertising, monitoring, training and
educating in company, schools, campuses, and healthcare.

2.5 Grounding Requirement

 It is important to keep this device grounded to ensure all of the modules function correctly.

Correctly grounding the device will also help prevent any electrical interference, lightening.
Etc. Also it helps reject minor interference that may disrupt the devices ability to function
smoothly. General rule of them, make sure the device is grounded when installing anywhere.

 Always use copper wire. When applied correctly the ground must be wrapped well to

ensure maximum conduction so it can reduce any high frequencies. The copper ground wire
should also be as short and thick as possible

 Installer must make sure that the two ends of the ground are well conducted and have

appropriate anti-rust properties.

 It is prohibited to use any other device as part of the grounding electric circuit.

 The area of the conduction between the ground wire and device’s frame should be no less

than 25 ㎡.

Chapter 4 - WEB NMS Operation

For setting configurations you can use the front panel; also you are able to control and set the
configurations on any computer by connecting the device to the web NMS Port. You should ensure that
the computer’s IP address is different from the THOR HDCOAX-4 IP address; otherwise, it would
cause an IP conflict.

4.1 Login

The default IP of this device is 192.168.0.136. We can modify the IP through the front panel.
Connect the pc and the device with net cable, and use ping command to confirm they are on the same
network segment.
E.G. the PC IP address is 192.168.99.252, we then change the device IP to 192.168.99.xxx (xxx can be
0 to 255 except 252 to avoid IP conflict).
Use any web browser to connect the device with the PC by inputting the Encoder & Modulator’s 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 “LOGIN” to start the device setting.

other heat-sink bores if necessary

 Checking the AC input within the power supply and ensure it is working, the connection

is correctly installed before switching on device

 Checking the RF output levels to stay within a tolerable range, if it is necessary
 Checking all signal cables have been properly connected
 Frequently switching on/off device is prohibited; the interval between every switching

on/off must be greater than 10 seconds.

Conditions needed to unplug power cord

 Power cord or socket damage.
 Any liquid that got into the device.
 Any stuff that could cause a circuit short
 Device in damp environment
 Device has suffered from physical damage; i.e. it fell off a rack.
