Chapter 1 Introduction 1.1 Product overview
EPS-SDM1004R is a MPEG2 encoder and DVB-T modulator. This unit integrates 4 AV sources into a RF network within the frequency range of 30~960MHz. The source could be from a variety of devices including satellite receivers, closed-circuit television cameras, Blue-ray players, and PC’s etc. It is equipped with a 1 RF input which acts as a combiner with other RF frequencies. This unit enables the distribution of an external source over a coax RF system. The signal from the external source can then be viewed via a terrestrial digital set top box. Typical applications include pubs, clubs, sporting venues, resorts, hospitals etc.

2.2 Installation Precautions This section to explain the cautions the users must know in some case that possible injure may bring to users when it’s used or installed. For this reason, please read all details here and make in mind before installing or using the product. General Precautions ;
Must be operated and maintained free of dust or dirty.
;
The cover should be securely fastened, do not open the cover of the products when the power is not off.
;
After use, securely stow away all loose cables, external antenna, and others.
Power precautions ;
When you connect the power source, make sure if it may cause overload.
;
Avoid operating on a wet floor in the open. Make sure the extension cable is in good condition
;
Make sure the power switch is off before you start to install the device
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.
;
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 25 m2.

Guard Interval In communications, guard intervals are used to ensure that distinct transmissions do not interfere with each other. These transmissions may belong to different users (as in TDMA) or same user (as in OFDM). The purpose of the guard interval is to introduce immunity to propagation delays, echoes and reflections, to which digital data is normally very sensitive. There are four possible options provided to be selected. They are 1/4, 1/8, 1/16, 1/32. User can shift the LEFT/RIGHT key to select and press ENTER to confirm.
Guard Interval 1/8 1/16 1/32 ¾
FEC This term refers to Forward Error Correction and its rates include 1/2, 2/3, 3/4, 5/6, and 7/8. After entering FEC submenu, the LCD display would show them, users just need press LEFT and RIGHT buttons to choose and press ENTER button to confirm.
FEC 1/2 2/3 3/4 5/6

Chapter 4 WEB NMS operation User not only can use front buttons for setting configuration, but also can control and set the configuration in computer by connect to web NMS Port. User should ensure that the computer’s IP address is different from the NDS3542’s IP address; otherwise, it would cause IP conflict.
4.1 login The default IP of this device is 192.168.0.136. We can change the IP from the front panel of the device. Then connect the pc and the device with Net Cable, and use ping command to confirm these two are in same Network or not. Here PC IP address is 192.168.99.252 so we change the Device IP to 192.168.99.xxx (xxx can be 0 to 255 except 252 to avoid conflict with PC IP address), then we need to use Web browser to connect the device with our PC. Put the IP of the device in the browser and Enter. When we connect the device it will display Login screen as Figure-1. Put the Username and Password (The default Username and Password is ‘admin’ and ‘admin’ respectively) then click on ‘Login’ to open the device setting.
