3.1 Acquisition Check
When user opens the package of the device, it is necessary to check items according to packing
list. Normally it should include the following items:
NK3316/32 IP QAM Modulator
User’s Manual
Power Cord
If any item is missing or mismatching with the list above, please contact local dealer.
3.2 Installation Preparation
When users install device, please follow the below steps. The details of installation will be
described at the rest part of this chapter. Users can also refer rear panel chart during the
installation.
The main steps of the installation include:
Checking the possible device missing or damage during the transportation
Preparing relevant environment for installation
Installing NK3316/32 IP Mux-Scrambling QAM Modulator
Connecting signal cables
Connecting communication port (if it is necessary)
3.2.1 De ice’s Installation Flow Chart Illustrated as follows：
3.2.2 Environment Requirement
Item Requirement
Machine Hall Space
When user installs machine frame array in one machine hall, the
distance between 2 rows of machine frames should be 1.2~1.5m and
the distance against wall should be no less than 0.8m.

Power
Requiring device power, air-conditioning power and lighting power
are independent to each other. Device power requires AC power
220V ±10% 50/60H or 110V ±10% 50/60H . Please carefully
check before running.
3.2.3 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 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.
3.2.4 Frame Grounding
6
NK3316/32 IP QAM M odula tor User Manual
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.
3.2.5 De ice Grounding
Connecting the device’s grounding rod to frame’s grounding pole with copper wire.
3.3 Wire’s Connection
3.3.1 Power cord connection
The power socket is located on the right of rear panel, and the power switch is on the left of
front panel. User can plug one end of the power cord to the socket and insert the other end to
AC power. 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.
Caution: Before connecting power cord to NK3316/32 IP QAM Modulator, user should set
the power switch to “OFF”.
3.3.2 Signal and NMS Cable Connection
The signal connections include the connection of input signal cable and the connection of output
signal cable.

Chapter 4 Web NMS Management
This device does not support the LCD operation, and the modification can only be operated
under Web NMS.
4.1 Login
The factory default IP address is 192.168.0.136 and users can connect the device and web NMS
through this IP address.
Connect the PC (Personal Computer) and the device with a net cable, and use ping command to
confirm they are on the same network segment. For instance, 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).
Launch the web browser an input the device 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.
