Chapter 1 Introduction
1.1 Product Overview
WT-ISDB-2ME series products are ’s all-in-one devices which integrate encoding
(MPEG-2, MPEG-4/AVC H.264) and modulation to convert V/A signals etc to digital RF
output.
Delay problem has been greatly reduced to achieve an extremely low value from the
encoding progress to the decoding terminals.
It adopts inner drawer-type structural design which greatly facilitates the change of
encoding modules (HDMI/CVBS/SDI/YPbPr/…) as needed. To meet customers’various
requirements, WT-ISDB-2ME is also equipped with 1 ASI input, and output with 2 ASI
ports and 1 UDP IP port.
The signals source could be from satellite receivers, closed-circuit television cameras,
Blue-ray players, and antenna etc. Its output signals are to be received by TVs, STB and
etc with corresponding standard.
With its various inputs available, our WT-ISDB-2ME series products are wildly used in
public places such as metro, market hall, theatre, hotels, restaurants and etc for advertising,
monitoring, training and educating in company, schools, campuses, hospital… It’s a good
choice to offer HD channels and more.

carefully check before running.
2.5 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 mm2.

Guard Interval
In communications, guard intervals are used to ensure that distant 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 keys to select and press ENTER to confirm.
FEC
This term refers to Forward Error Correction and its rates include 1/2, 2/3, 3/4, 5/6, and

Chapter 4 WEB NMS Operation
User not only can use front buttons to set configuration, but also can control and set the
configuration in computer by connecting the device to web NMS Port. User should ensure
that the computer’s IP address is different from the WT-ISDB-2ME’s IP address; otherwise,
it would cause IP conflict.
4.1 login
The default IP address of this device is 192.168.0.136. (We can modify the IP through the
front panel.)
Connect the PC (Personal Computer) and the device with net cable, and use ping command
to confirm they are on the same network segment.
I.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 web browser to connect the device with 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.
