Power
Requiring device power, air-conditioning power and lighting
power are independent to each other. Device power requires AC
power 220V 50Hz. Please carefully check before running.
2.2.3 Grounding Requirement
All function modules’ good grounding designs are 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 cable’s 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.

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.
Caution:
Before connecting power cord to NDS3244S Multi-Channel Encoder, user should
set the power switch to “OFF”.
2.4 Signal Cable Connection
The signal connections include the connection of input signal cable and the connection of
output signal cable. The details are as follows:

Chapter 3 WEB NMS Operation
NDS3244S does not support front buttons and LCD, users can only 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 NDS3244S IP address; otherwise, it would
cause IP conflict. This user manual will take module 1 as an example.
3.1 login
The default IP address of NDS3244S (3 NMS ip addresses for 3 modules respectively) is
10.0.0.101, 10.0.0.102 and 10.0.0.103.
The module which closes to power is 10.0.0.101
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’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.
