The Paxton Net2 plus control unit connects to the central administration PC using an RJ45 plug into a standard TCP/IP Ethernet network. This greatly increases the flexibility of installation options on sites that have LAN/WAN networks. The Net2 plus control unit also has an RS-485 connection. This means it can be connected to other Net2 Plus or Net2 Classic control units using a dedicated CAT5 cable.

One Paxton Net2 plus control unit can be the network interface to the LAN and also run a wired RS485 daisy chain of other Net2 plus or Net2 classic units, removing the need for an independent TCP/IP to RS485 converter. Net2 plus is also available with a Power over Ethernet (PoE) power supply. PoE is a technology that allows both power and data to be passed along Ethernet cabling. Net2 plus with PoE simply plugs straight into the existing LAN using a standard RJ45 plug (providing it is powered by either a compatible PoE switch or a PoE injector).

Control units are sold as a PCB only, within a plastic housing, or mounted within a 2A boxed metal/plastic mains monitored backup power supply. The Net2 plus unit now comes with a PoE+ power supply in a metal/plastic cabinet; no separate mains supply back-up required.
