level glasses for window
Wall 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 power 100-240V 50-60Hz. Please
carefully check before running.
2.2.3 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.
Coaxial cables outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
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

HP8516T 8 CH Mux DVB-T Modulator User’s Manual
7
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 25mm2.
2.2.4 Frame Grounding
All the machine frames should be connected with protective copper strip. The
grounding wire should be as short as possible and avoid circling. The area of the
conduction between grounding wire and grounding strip should be no less than 25mm2.
2.2.5 Device Grounding
Connecting the device’s grounding rod to frame’s grounding pole with copper wire.
2.3 Wire’s Connection
The grounding wire conductive screw is located at the right end of rear panel, and the
power switch, fuse, power supply socket is just beside ,whose order goes like this,
power switch is on the left ,power supply socket is on the right and the fuse is just
between them.
Connecting Power Cord
User can insert one end into power supply socket, while insert the other end to AC
power.
Connecting Grounding Wire
When the device solely connects to protective ground, it should adopt independent
way, say, share the same ground with other devices. When the device adopts united
way, the grounding resistance should be smaller than 1Ω.

Chapter 3 Web-based NMS Management
Users can only control and set the configuration with the web Brower in the PC.
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 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
are defaulted as “admin”.) and then click “LOGIN” to start the device setting.
