Chapter 2 Installation Guide
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 free of dust or dirty.
The cover should be securely fastened, do not open the cover of the products when the
power is on.
After use, securely stow away all loose cables, external antenna, and others.
2.2 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

It can be covered with wallpaper, or brightness less paint.
Fire Protection
Fire alarm system and extinguisher
Power
Requiring device power, air-conditioning power and lighting
power are independent to each other. Device power requires
AC 110V±10%, 50/60Hz or AC 220V±10%, 50/60Hz. Please
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.

Chapter 3 WEB NMS Operation
3.1 Encoder login
The default IP address of this device is 192.168.0.136. 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 1 to 254 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.
