NH-310S is an Ethernet over coax Slave. It is designed to connect with NH-310H EoC Managed Master
for MDU and MTU applications that leverage the two most popular network connections for home use:
10/100Mbps Ethernet and coaxial cable connection. It is a plug & play cost effective MDU and MTU solution that
eliminates the pain in modification and high infrastructure cost. With the data transmission up to 200 Mbps,
it meets the growing demand for high speed multimedia services for buildings, apartments, hotels, resorts and
other places that need a high bandwidth network.

 

It is a norm that MDU and MTU are equipped with wired network that simply transfer small files and shared applications, but the need for triple play services like transferring large multimedia files such as music, video, photo and deliver high speed VOIP data are ever increasing.

 

This is why NH-310H/S is designed to be a cost effective MDU and MTU solution. With plug & play, this simply eliminates the pain in modification and high infrastructure cost. With the data transmission up to 200Mbps and link establish under -145dBm/Hz noise floor, it meets the growing demand for high speed multimedia services. Most importantly, with MDU and MTU applications, it allows networking for any locations such as buildings, apartments, hotels, resorts, sports center and other places that need a high bandwidth network.

 

Flexible Configuration

NH-310H can connect to another NH-310S via a coaxial cable, administrators can install these devices easily for MDU/MTU applications. The NH-310H supports up to 60(maximum) NH-310S Slave.

MDU/MTU Solutions

The Netsys NH-310H is designed to be a cost effective MDU and MTU solution capable of high-speed data transmission over existing (or new) coaxial cable networks. With the data transmission up to 200Mbps and a noise floor of up to -145dBm/Hz, it meets the growing demand for high speed multimedia services. Built-in splitters allows the data signal to be carried over the same coax cable as a TV or STB signal. The NH-310H Master unit is installed at the central location, and can be connect with up to 60 NH-310S Slave, making it the ideal solution for MDU and MTU settings. The NH-310H comes ready for instant plug and play operation, eliminating the pain in modification and high infrastructure cost. The Netsys NH-310H Ethernet Over Coax MDU Master, combined with the Netsys NH-310S MDU Slave, provides a simple and cost-effective solution for creating standards-based coaxial cable networks and distributing High-Speed Internet Access in hotels/motels and other multi-tenant buildings.

1. What is NH-310S related products?

 

NH-310S can fully compatible with NH-310H.

 

2. The link is failed between NH-310H and NH-310S. The functionality of NH-310S is abnormal.

 

The output level of voltage is too high for short connection. It must use the attenuator to be connected with MDU Master NH-310H and Slave NH-310S to attenuate the transmission power level to -10dBm(5M-850MHz) at least.

 

3. POWER indicator does not light up (green) after power on.

 

Check the power adapter plugging to another device or check another power adaptor plugging NH-310H/S that is functioning properly. If these measures fail to resolve the problem, please replace a power adaptor via a qualified vendor. NH-310H/S supports DC 12V/1A power adaptor.

 

4. Link indicator does not light up (green) after making a connection.

 

Network interface (ex. a network adapter card on the attached device), network cable, or switch port is defective.

• Power off and re-power on the VDSL bridged.

• Verify that the bridge and attached device are power on.

• Be sure the cable is plugged into both the bridge and corresponding device.

• Check if the proper cable type is used and its length exceed specified limits.

• Check the bridge on the attached device and cable connections for possible defects.

• Replace the defective bridge or cable if necessary.

 

5. Why the long HomePNA test passed but TV service does not work properly?

 

The problem is not with the HomePNA network. Check your DSL service or replace the RG and/or STB equipment.

 

6. We connected HCNA port of Master with HCNA port of Slave via a splitter but the connection still can’t be established or not stable. But when we connect TV port of  Master with HCNA port of Slave via splitter then the connection’s ok.

 

The TV port of Master connect to HCNA port of Slave is not correct, It why can link establish the reason using a short cable, causing HPNA signal of NH-310S too strong and pass to HPNA port of NH-310H through TV port (50MHZ high pass filter build in) of NH-310H, so you can create a weak connection, but as long as extend coaxial over 350m length or plug a -20db attenuator, this link will be loss. We recommend add a -10dB attenuator (5M-850MHz) to establish a basic connection.

 

7. About rate control of Slave, can we create a new one or modify them?
  1. Only select the rate of 12 speed modes as Full Speed/ 512k/ 1M/ 2M/ 3M/ 4M/ 6M/ 8M/ 10M/ 16M/ 20M/ 30M for EOC Slave. Therefore you can not create a new kind of rate.

 

8. NH-310H signal source ? To CATV signal source only or to common distribution of Antenna signal also.

 

You can use the CATV signal, you can also use the Antenna signal as long as not to conflict with the HPNA signals, due to HPNA working frequency is between 12Mhz~44Mhz, CATV and Antenna is over 50Mhz.

 

9. I connect TV signal to NH-310H/S, why TV signal can’t show on TV.

 

TV signal is too weak or other factors.

Please verify that the following items to help you clarify the problem:
1. Verify coaxial cable use RG59 75 ohm cable.
2. Verify TV signal source and TV if available.
3. Check TV signal need to over 50MHz that will be passed.
4. Add TV signal repeater before NH-310H if TV signal source is too weak.

5. Add attenuator before TV if TV signal is too strong.

 

Notes:

  1. 1. Weakened by the output television signal is due to environmental factors. NH-310H/S support TV signal pass through, but can not guarantee to be able to maintain an appropriate TV signal output to TV, If the connection distance is too long lead to output of TV signal no signal or attenuation.
  2. 2. Please note NH-310H/S TV signal input power is unlimited, user does not need add the attenuator before NH-310H/S to weaken the TV signal source.
  3. 3. If TV signal is too strong, leading to the advent of television ripple, please add an attenuator before TV.
4. HPNA3.1 must use 75 ohm coaxial cable. If use 50 ohm impendence, the performance will be less than half.

 

10. How much node(Mac Address) can be connected to behind of the NH-310S.

 

Each of the NH-310S can only be connected to 16 nodes (Mac Address).
