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

User not only can use front buttons to set configuration, but also can 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 NDS3542’s IP

address; otherwise, it would cause IP conflict.

4.1 Encoder 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 the default Username and Password are “admin”.) and then click “LOGIN” to
start the device setting.
