INSTALLING THE 821 ETHERNET EXTENDER
The Enable-IT 821 Ethernet Extender kit has a max distance reach of up to 3,280ft (1km) over
any 1-pair wiring (Telephone, Coax, or Category rated) between the 821 units.
You can add additional 328ft (100m) onto the end of each 821 LAN output ports for a total
distance of 3,936ft (1.2km) from device extension to device extension.
For highest performance use lower gauge wiring like 14AWG ~ 24AWG for the interlink wiring.
We highly recommend that you perform a quick out of the box test to ensure the working order of your
Enable-IT 821 Ethernet Extender units prior to installing. This will also serve to familiarize you with
how easy the process should be. Follow the steps below to perform the Out Of the Box Test.!
!
Step 1 - Attach the 821 DC power adapter to the 821 Injector unit and to your AC outlet. The green PWR LED !
will indicate the unit is receiving power as well as the 821 56V 65W DC Power Adapter green LED.
Step 2 - Connect the 821 units together using one of the Ethernet LAN Patch cords provided – attach to the "
RJ-45 Interlink port on each 821 unit as shown by the green line connecting the ports in the diagram
above. The PWR and PLC LED indicators on each of the 821 units will provide visual operational
status of the 821 Ethernet Extension kit.!
!
Step 3 - Attach and test and to confirm your LAN Equipment works through the 821 extension, connect
your Ethernet LAN to the 821 Injector unit LAN port and the remote device/s to the 821 Extender
LAN port and test connectivity. This confirms basic proper operation of the units.
Performing the On-Site Installation
After removing the Enable-IT 821 Ethernet Extender Kit from the box, and performing the Out Of
The Box Testing (OOTBT), all that remains to install the unit on-site is to build the interconnect
wiring and attach the LAN device cabling with the provided Ethernet Patch cords.
Building the 821 Interlink Wiring
The most important aspect of the installation is the correct wiring of the Interlink cabling.
The 821 Interlink port (RJ-45 interface) carries this 1-pair signaling and power over the RJ-45
(pins 1 & 2) - used as transport. If you use more than 1-pair of wiring, such as a CAT5 segment,
the remaining RJ-45 pins 3, 5 and 7 carry positive and RJ-45 pins 4, 6 and 8 carry negative
signal for distance.

For all wiring you will need to crimp a RJ-45 Male head to each end of the contiguous wire run
and using the following (pins 1 & 2) straight through. We recommend using a category rated
twisted pair cable as it is optimized for high throughput frequencies isolated from cross-talk
noise. Insert the completed RJ-45 ends into the 821 Interlink port on each 821 unit.
Cabling Devices to The Enable-IT 821 Extended Ethernet Kit
Attach your remote LAN device to the 821 Extender unit LAN port with Ethernet patch cord
provided. Attach your local LAN to the 821 Injector LAN port with Ethernet patch cord provided.
Attach the 56V - 65W power adapter to the 821 Injector unit.
Attach your local Interlink cabling end to the 821 Injector unit Interlink port – Then do the same
for the remote end and plug into the 821 Extender unit Interlink port. The Green PLC and PWR
LED should both be solid, indicating they each see the remote partner. There is no sync delay!
Your equipment should now be powered up and functioning.
The LED indicators will provide visual operational status of the 821 Ethernet Extender units.
Troubleshooting
First examine the backbone wiring pair and make sure you have solid connections. The PWR and
Interlink PLC LED will be lit solid Green on each 821 unit. The units sync instantly and have no delay.
if either fail to light up…. Then follow the steps below:
1) Make sure your wiring is straight through and not connected to any Telco punch down
blocks; If so remove from the block and use Telco butt clips to bridge wire.
2) Check for a firm connection of the RJ-45 connections in each 821 unit, and power is
applied to the 821 Injector unit. The 821 Extender unit should be receiving power.
3) You can easily isolate any issue by performing an Out Of The Box Test (OOTBT). This
test will confirm the correct working order of your Enable-IT 821 Ethernet Extender Kit.
This will point to a possible issue with your long distance Interlink wiring being
affected by possible outside interference.
