Initial Device Setup
NOTE: A minimum of two G.hn Coax Adapters are required to create a proper connection. Follow
Steps 4-8 to add additional G.hn Adapters to your network.
1. Plug the power supply into the Coax Adapter into the power outlet nearest to the
network device (Eg. Modem, Router, or Access Point).
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.

4. Plug the power supply into the additional 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 light up GREEN. The Coverage LED on the Coax Adapter
should now be RED or GREEN or ORANGE.
7. 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 slow blinking – opening a
configuration period of 120 seconds). Upon successful connection of the Adapters, the
Security LED will light up GREEN and the Coverage LED will light up RED or GREEN or
ORANGE.
8. If the connection process is not successful, please refer to the trouble shooting steps in
section F.
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-1200 unit, then return to step 7 to reconfigure it.
Adding Additional Adapters/Devices
Follow steps 3-7 in Part B to add additional Adapters/devices to the Coax Network (up to
32 devices). For each additional adapter added, press the “Config” button on one of
the Adapters in an already paired network, then on the new device, so they can pair
and transmit data successfully.
Congratulations! You Are Done!

Troubleshooting
The following information should help you diagnose basic setup or installation problems.
COVERAGE LED is OFF: Plug the problem GCA-1200 unit into a power socket next to
the other GCA-1200 unit; both GCA-1200 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 part B and
follow the installation steps.
ETHERNET LED is OFF: If the ETHERNET LED fails to light up, check that the LAN port of the
GCA-1200 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.
