Chapter 1 Quick Installation

A

Understanding Your G.hn Coax Adapter

NOTE: The following steps show how to create or add onto a G.hn Coax Network (A minimum of two

G.hn Coax Adapters are required to create a proper connection.)

 If this is the first time you are setting up a G.hn Coax Network please continue to Section B.

 If you already have an established G.hn Coax Network, and are adding an additional adapter please skip to Section C. Follow Steps 4-8 to add additional G.hn Adapters to your network.

B

Creating a New G.hn Coax Network

1. Plug the power supply into the Coax Adapter and into the power outlet nearest to the network device

(Eg. Modem, Router, or Access Point). The LEDs will briefly turn on.

5

2. Connect the coaxial cable to the “IN” of the Coax Adapter and to a cable wall outlet.

3. Ensure that your network device is powered on. Connect the Coax Adapter to the LAN port of the network device with an Ethernet cable. Wait for 10 seconds for the Coax Adapter’s Ethernet LED to light up GREEN indicating a stable connection.

C

4. Plug the power supply into the Coax Adapter and into the power outlet nearest to the remotely located

Internet-enabled device (Eg. TV, PC, STB, DVR, Etc.).

5. Connect the coaxial cable to the “IN” of the Coax Adapter and to a cable wall outlet.

6. Connect the Coax Adapter to the device with an Ethernet cable. The Ethernet LED on the Coax

Adapter should be flashing GREEN . The Coverage LEDs on the Coax Adapters should now be lit

(they will be GREEN, ORANGE , or RED depending on the strength of the connection.)

6

Note: The “TV” port on the Coax Adapter is meant for traditional Cable TV services. We do not recommend using the Coax Adapter if you receive Cable TV/Internet services.

7. We recommend a secure network. If the Security LED is off, press the “Config” button on each of the two Coax Adapters for 3 seconds consecutively (until the Security LED starts blinking). You will have 2 minutes to complete this step once the first “Config” button is pressed. Upon successful connection of the Adapters, the Security LED will light up GREEN and the Coverage LED will light up GREEN, ORANGE , or RED .

Note: Pressing the Config button – located on the side of the device for more than 5 seconds resets the security settings (10 seconds or more performs a factory reset). If you accidentally reset the GCA-6000 unit, repeat step 7 to secure the network.

8. If the connection process is not successful, please refer to the troubleshooting steps in section F.

D

Follow steps 4-8 in Part C to add additional Adapters/devices to the Coax Network (up to 32 devices). For each additional adapter added, press the “Config” button on an already secured Adapter, then on the new adapter, so they can pair and transmit data successfully.

E

F

Troubleshooting

The following information should help you diagnose basic setup or installation problems.

COVERAGE LED is OFF: Plug the problem GCA-6000 unit into a power outlet next to the other

GCA-6000 unit; both GCA-6000 having been connected by Ethernet cable to their respective devices e.g.

PC, Router, Set Top Box....etc.). After 10 seconds (approx), the COVERAGE LED should light up

GREEN . If not, first Factory reset both devices by pressing the “Config” button on each for more than 10 seconds. Then, go to section B and follow the installation steps.

7

ETHERNET LED is OFF: If the ETHERNET LED fails to light up, check that the LAN port of the

GCA-6000 unit is connected firmly to the LAN port of the other device. To check the condition of the

Ethernet cable, use another cable to test the same connection.

8

Chapter 2 Introduction

Comtrend’s ITU-T G.hn networking standard compliant Ethernet adapter provides the best quality data transmission at high-speed. The GCA-6000 allows users to extend a local area network via existing coax cables, eliminating the need for extra Ethernet wiring.

2.3 How to understand the COVERAGE LED colors

The COVERAGE LED displays quality of the network and provides important information that will provide solutions to common questions, such as why a High Definition (HD) movie is not showing or shows with pixels. The COVERAGE LED indicator will vary its color depending on the estimated speed of the Coax connection. The speed is measured in Megabits Per Second (Mbps).

Color

RED

Information

The current connection has standard quality, normal Internet activities (ex. 20Mbps) are possible but the Powerline is unable to transmit either a Standard Movie or High Definition (HD) Movie.

ORANGE The current connection has good quality and Internet activities

(ex. greater than 20Mbps and less than 40Mbps) such as transmitting a Standard Movie and HD Movie are possible.

GREEN The current connection has excellent quality and Internet activities (ex. greater than 40Mbps) such as transmitting multiple Standard Movies and HD Movies are possible.

11

2.4 Point-to-Point Network

CASE 1: Estimated throughput is less than 20 Mbps. The Coax channel is not able to transmit an

SDTV channel. The COVERAGE LED will be RED as shown in the following figure:

CASE 2: Estimated throughput is greater than 20 Mbps but less than 40 Mbps. The coax channel is able to transmit an SDTV channel, but not two SDTV channels simultaneously or one HDTV channel.

The COVERAGE LED will be ORANGE as shown in the following figure:

CASE 3: Estimated throughput is greater than 40 Mbps. The coax channel is able to transmit two

SDTV channels simultaneously or at least SDTV one HDTV channel. The COVERAGE LED will be

GREEN as shown in the following figure:

12

2.5 Point-to-Multipoint Network

In the case where the Coax network is composed of three or more adapters, similar situations could arise as with a point-to-point network.

CASE 1: The COVERAGE LED in G.hn adapter 2 and G.hn adapter 3 will show the estimated level of the

Coax link receiving from G.hn adapter 1.

CASE 2: The COVERAGE LED in G.hn adapter 1 will show the estimated level of the Coax Link from which it is receiving the most amount of traffic at any given time. For example, if G.hn adapter 1 is receiving traffic at 50Mbps from G.hn adapter 2 and is receiving 25Mbps from G.hn adapter 3, the COVERAGE LED will show the level with reference to the G.hn adapter 2 link, as shown in the following figure.

13
