2N® 2Wire - How to use it?

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 leader unit where your Ethernet cable ends and 2 wire cabling begins.
• Plug in the Ethernet and 2 wire cable into the leader unit.
• 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.

  PoE

  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.

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.

Single Leader & multiple Followers

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

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 an unpairing/pairing procedure.
If you do not you may experience network conflict issues.

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 Leader and connect the Follower 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 ‘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 ‘PoE’ 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 Leader & single Follower pairing scenario, it doesn't matter which adapter you put into pairing/seek mode first.

But if you wish to 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 pairing procedures for each connected Follower.

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