Akuvox Ethernet to 2-Wire Adapter Kit (NX-2 + NC-2)
This kit pairs an NX-2 (2-wire to Ethernet converter) with an NC-2 (Ethernet to 2-wire converter), giving a complete point-to-point solution for extending a standard IP network connection over existing 2-wire cabling. It’s PoE powered and built for old-building retrofit projects where running new Ethernet cable across the full distance isn’t practical.

SKU: 2 Wire Adapter Kit (NX-2&NC-2) · Door Station Accessory
Adapter Kit
Matched Pair for Point-to-Point Links
NX-2 converts the 2-wire signal back to Ethernet at one end, NC-2 converts Ethernet to 2-wire at the other.
PoE Powered
Both units run on Power over Ethernet, avoiding the need for separate local power supplies at each end.
Long Transmission Distance
Designed for old building retrofit, extending an IP connection well beyond typical Ethernet cable-run limits.
Compact Matched Enclosures
Both units share the same slim 113 x 48 x 25mm form factor, easy to fit into cabinets at either end.

Core Features
Detailed Breakdown
Matched Point-to-Point Kit: NX-2 sits at the network end, converting the incoming 2-wire signal back to a standard 100Mbps Ethernet connection. NC-2 sits at the far end, converting Ethernet to 2-wire, ready for a compatible door phone or monitor.
PoE Powered Throughout: Both units draw power over Ethernet, simplifying installation by removing the need for separate local power supplies at either end of the link.
Long Transmission Distance: Built specifically for old-building retrofit projects, extending a usable IP connection over existing 2-wire cabling well beyond standard Ethernet cable-run limits.
Compact, Matched Enclosures: Both the NX-2 and NC-2 share the same slim 113 x 48 x 25mm housing, making them easy to fit into cabinets or cupboards at either end of the run.

Frequently Asked Questions
Q&A
This kit extends a standard Ethernet network connection over existing 2-wire cabling, useful when you need to reach a distant point in an older building without running new network cable the whole way. It’s a matched pair: NC-2 puts the signal onto the 2-wire cable, NX-2 takes it back off at the other end.
An NC-2 on its own is typically used to extend the reach of an existing NS-2 switch to a compatible Akuvox door phone or monitor. This kit adds an NX-2, which converts the 2-wire signal back into standard Ethernet at the far end, useful for extending a general network connection rather than just an Akuvox intercom device.
Both units are PoE powered, so as long as PoE is available at the network end, no separate local power supply should be needed at either unit.
Yes, it can extend the network connection to a point where an Akuvox IP door phone or monitor is then connected via standard Ethernet. For Akuvox’s own 2-wire devices (like the R20A-2 or S562W-2), an NS-2 switch is typically used instead, with the NC-2 as an optional distance extender.
Their compact 113 x 48 x 25mm size makes them easy to fit into a riser cupboard, ceiling void, or comms cabinet at each end of the 2-wire run. Sipko Security determines the best placement as part of the installation design.
