Product features

  • Using legacy analog 2 wire cabling for IP intercom connection including PoE power supply
  • Long range Ethernet extension over 2 wires
  • Easy configuration, no IP address and network setup required, plug&play

Package contents – what you should get with the delivery

  • 2 pieces of 2N® 2Wire converter units
  • 1 power supply adapter

Product use

  • Install 2N® 2Wire master unit where your Ethernet cable ends and 2 wire cabling begins.
  • Plug in the Ethernet and 2 wire cable into the master unit.
  • Install 2N® 2Wire slave 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 master unit.
  • Either of the units can be master or slave. Master unit is the one with connected power supply while slave is powered via 2 wires.
  • Blue Power LED indicators should indicate that both units are powered.


  • 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

LED Indicators

  • Power: Blue – Power ON

Use case scenarios

Single Master & Single Slave

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.

Single Master & multiple Slaves

This is similar to a single Master / Slave configuration in that it works straight out of the box. 
Multiple Slaves can be wired into a single Master. Again make sure to connect the 2 wire correctly to each adapter. Positive to positive & negative to negative.

Multiple Masters & Multiple Slaves

If this configuration is required and you are installing multiple Master adapters on to a single network, it is very important to perform an unpairing/pairing procedure.
If you do not you may experience network conflict issues.

Be aware


Pairing procedure must be executed for multiple Master adapters if they're in a single network!!

How to pair/unpair?

Each adapter has a small hole labelled ‘Grp’. There is a button inside this hole that is used to initiate the unpairing/pairing procedures.

To access the button you will need a small tool like a toothpick, narrow screwdriver or a paperclip.

1) To perform unpairing/pairing procedures the adapters must be powered up.
     So you must connect the power supply to the Master and connect the Slave via the 2 wire connection.

2) DO NOT connect them to the network or the IP device….. yet.
3) You should do this on all adapters before attempting a pairing procedure.

Pairing procedure

To perform a pairing procedure press and hold the ‘Grp button for 2 seconds. When you release the button the ‘TWP’ 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’ will become static, letting you know pairing is complete.

Unpairing procedure

To unpair an adapter press and hold the ‘Grp’ button for 10 seconds, until you see all lights on the adapter go off.

After unpairing is complete you should see only the power light illuminated.

About pairing/unpairing

In a single Master & single Slave pairing scenario, it doesn't matter which adapter you put into pairing/seek mode first.

But if you wish to have multiple Slaves connected to a single Master, then you must connect all Slaves via the 2Wire connection to the Master first, then run individual pairing procedures for each connected Slave.

  • To do this you must initiate the pairing/seek mode on the Master first and then the first Slave.
  • Then repeat this for each Slave connected to the Master.

But remember, unpairing & pairing is only needed when installing more than one Master adapter on a single network.
