Chapter 1 Introduction
1.1 Product Overview
The Thor 4-ADHD series encoder is an all-in-one device that integrates encoding (MPEG-2,
MPEG-4/AVC H.264), modulation, and convert HDMI/YPbPr to a digital RF output sigal.
To meet various requirements, the 4-ADHD is also equipped with 1 ASI input, and output with 2
ASI ports and 1 IP port.
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 in public places such as the mall, market hall, theatre, hotels,
restaurants and etc for advertising, monitoring, training and educating in company, schools,
campuses, and healthcare.

This section is 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.
2.1 General Precautions
Must be operated and maintained in an area free of dust and debris.
The cover should be securely fastened, do not open the cover of the chassis when the power is on.
This will also void Thor’s manufacturer’s warranty.
After installation, securely stow away all loose cables, external antenna, and others.
2.2 Power precautions
Be careful when connecting a power source to the device.
Do not operate in wet or damp areas. Make sure the extension cable is in good
condition
Make sure the power switch is off before you start to install the device

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 4-ADHD’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 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.
