2N 2Wire is a set of two convertor units that lets you connect any IP device installed at locations with no IP infrastructure to your network. Connect the device, such as an IP intercom, to one unit and a switch to the other unit. Then connect both convertor units to each other using the existing analogue wiring. This will transmit audio and video as well as supply power.
Prerequisites
- 2N 2Wire
(2 pieces of 2N 2Wire converter units and 1 power supply adapter)
Specifications:
- Speed: 10/100 Base T, half/full duplex, auto-negotiation
- IEEE 802.3 af/at 40Watt Compliant PoE+
- Cable Type: 2Wire, Cat 5e., Cat 6. or similar
- Impedance: 25Ω to 100Ω
- Transmit Coverage: Typical 720ft (220m) @ Cat6 with PoE at far end;
up to 2460ft (750m) possible; depends on wiring and interference
Product features
-
Using legacy analog 2 wire cabling for IP intercom connection including PoE power supply
-
Easy configuration, no IP address and network setup required, plug&play
-
Powering the IP-connected devices via PoE is possible up to a distance of 220m,
twice the maximum Ethernet specification cable length. -
You can connect up to 2 pairs of 2N 2Wire convertor units to a single switch.
This means you can connect an intercom to several indoor stations as well as an IP camera.
The pairing procedure must be proceeded first.
Basic installation
- Install 2N 2Wire leader unit where your Ethernet cable ends and 2 wire cabling begins, plug in them.
Do not connect 2N 2Wire units to PoE ports. If you don't have any non-PoE ports available,
make sure to disable PoE on the port you're going to connect 2N 2Wire to.
- Install 2N 2Wire follower unit where you need to convert 2 wire cable back to Ethernet at a remote location. Please observe polarity of the 2 wires.
-
Connect the provided power supply to the leader unit.
-
Either of the units can be leader or follower.
Leader unit is the one with connected power supply while follower is powered via 2 wires. -
Blue Power LED indicators should indicate that both units are powered.
Use case scenarios
-
Single leader & Single follower
-
- This is the simplest configuration and works straight out of the box.
- Just make sure you connect the 2 wires correctly to each adapter. Positive to positive & negative to negative.
- This is the simplest configuration and works straight out of the box.
-
Single leader & multiple followers
- This works straight out of the box as well.
- Multiple followers can be wired into a single leader, max. 3 followers can be connected to a leader.
- Again make sure to connect the 2 wire correctly to each adapter. Positive to positive & negative to negative.
- This works straight out of the box as well.
-
Multiple leaders & Multiple followers
- If this configuration is required and you are installing multiple leader adapters on to a single network,
it is very important to perform the pairing procedure (described below the pictures),
otherwise you may experience network conflict issues.

The pairing procedure
All units are in join mode. They will find each other and establish basic level encrypted communication.
To use more leaders in the same network, we must return the units to an un-joined mode and then join them again.
In case of adding another unit (e.g. as a replacement), you must repeat all the procedure again.- Un-joining mode
-
- Connect the power supply to the leader and connect the follower via the 2 wire connection.
Do not connect them to the network or the IP device yet. - Press and hold the ‘Grp’ button for 10 seconds, until you see all lights on the adapter go off.
Then you should see only the power light illuminated.
- Connect the power supply to the leader and connect the follower via the 2 wire connection.
-
- Joining mode
In a single leader & single follower joining scenario, it doesn't matter which unit you put into this mode first.
If you have multiple followers connected to a single leader, then you must connect all followers via the 2Wire connection to the leader first, then run individual joining procedures for each connected follower. To do this you must initiate the joining mode on the leader first and then the first follower. Then repeat this for each follower connected to the leader.

-
- Connect the power supply to the leader and connect the follower via the 2 wire connection.
Do not connect them to the network or the IP device yet. - Press and hold the ‘Grp’ button for 2 seconds.
After release, the ‘PoE’ light will begin steadily blinking
letting you know that the adapter is in ‘seek’ mode and is looking for another adapter to pair to.
Once an adapter has found another adapter to pair to the ‘TWP LED’ will become static,
letting you know pairing is complete.
- Connect the power supply to the leader and connect the follower via the 2 wire connection.
