Foreword
Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer, Statement
of Conditions and Safety Warnings.
Netsys’ NH-310C is the latest technological innovation of HomePNA3.1 Ethernet over coaxial cable end point. NH-310C is designed
for home and office applications that leverage the two most popular networ connections for home use: 10/100Mbps Ethernet
connection and coaxial cable connection.
It is a norm that homes and offices are equipped with wired networ that simply transfer small files and shared applications, but the
need for triple play services li e transferring large multimedia files such as music, video, photo and deliver high speed VOIP data
are ever increasing.
This is why NH-310C is designed to be a cost effective home networ ing solution. With the data transmission up to 200Mbps and
distance can withstand 60dB of the attenuation; it meets the growing demand for high speed multimedia services. With plug & play,
this simply eliminates the pain in modification and high infrastructure cost. Most importantly, to be able to support point-to-point and
point-to-multipoint applications allow networ ing for any locations such as home, office, sports center, buildings, apartments, hotels,
resorts and other places that need a high bandwidth networ .
Caution:
The NH-310C is for indoor applications only. This product does not have waterproof protection, please do not use in outdoor
applications.

Chapter 3. Installation
3.1 Hardware Installation
This chapter describes how to install the modem and establish the networ connections. You may install the modem
on any level surface (ex. a table or shelf). However, please ta e note of the following minimum site requirements
before you begin. NH-310C needs paste four rubber feet on the bottom to avoid scratching, please refer to
Appendix E: Attaching Rubber Feet.
3.2 Pre-installation Requirements
Before the start of actual hardware installation, ma e sure to provide the right operating environment, including power
requirements, sufficient physical space, and proximity to other networ devices that are to be connected. Verify the
following installation requirement:
• Power requirements: 5-12VDC / (1A or above)
• The device should be located in a cool dry place, with at least 10cm / 4in of space at the front and bac
for ventilation.
• Place the device away from direct sunlight, heat sources, or areas with a high amount of
electromagnetic interference.
• Chec if networ cables and connectors needed for installation are available.
• Avoid installing this device with radio amplifying station nearby or transformer station nearby.

3.3 General Rules
Before ma ing any connections to the modem, ta e note the following rules:
• Ethernet Port (RJ-45)
All networ connections to the end point Ethernet ports must be made using Category 5 UTP or above for 100
Mbps, Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling maybe use between the MUX or HUB and an end node.
• HCNA Port (Coaxial connector)
All Home networ connections we recommend use RG-59 75Ω coaxial cable and lin establish under -160dBm/Hz
noise floor.
• ulti-Splitter
All Home networ connections could be use Multi-Splitter or use mix of them as you would li e to connect an end
point device.
Multi-Splitter

3.4 HCNA Connections
The modem has been designed to operate on the coaxial cable installed in homes throughout the world. They utilized
the same cable and connectors commonly used for television.
The modem has 2 x Ethernet ports. One port is used to connect to the ISP to provide Internet access and the other
port is used to connect devices such as HUB, concentrator, bridge or router. The device attached to these ports must
support auto-negotiation.
The 2x Coaxial connector are used to connect to TV or coaxial wall soc et to another modem that connect its RJ-45
to the LAN card of another set of PC, noteboo , or other internet access device or coaxial connector to TV or set top
box.
The modem’s coaxial connector must support the transmission of data up to 200Mbps across the existing coaxial
cable and lin establish under -160dBm/Hz noise floor. But ma e sure that the connector is inserted properly and
loc .
Ethernet cable used must conform to FCC standard to ensure data integrity and it should not exceed 100meters
(328feet).
The NH-310C supports up to 10(maximum) NH-310C Endpoints.

Appendix A: Cable Requirements
A CAT 3, 4 or 5 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the modem. A
10Base-T cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of
the 10Base-T cable is referred to as an RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2,
3 and 6 for data transmission purposes. (Table A-1)

Appendix C: Troubleshooting
Diagnosing the odem’s Indicators
The endpoint can be easily monitored through its comprehensive panel indicators. These indicators assist the networ
manager in identifying problems the hub may encounter. This section describes common problems you may
encounter and possible solutions.
1. Symptom: POWER indicator does not light up (green) after power on.
Cause: Defective External power supply
Solution:
Chec the power plug by plugging in another that is functioning properly. Chec the pow
er
adapter
with another device. If these measures fail to resolve the problem, have the unit power
supply replaced by a qualified distributor.
2.
Symptom: Lin indicator does not light up (green) after ma ing a connection.
Cause: Networ interface (ex. a
networ adapter card on the attached device), networ cable, or switch
port is defective.
Solution:
2.1 Verify that the endpoint and attached device are powered on.
2.2 Ma e sure the cable is plugged into both modems and corresponding device.
2.3 Verify that the proper cable type is used and its length does not exceed specified limits.
2.4 Chec the modem on the attached device and cable connections for possible defects.
2.5 Replace the defective modem or cable if necessary.
