Net2 is a networked access control system. A networked system gives the advantages of central control, event reporting and flexible control over users’ access. Each control unit is part of a network but can run independently making its own decisions and remembering events. The 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 a RS485 connection. This means it can be connected to other Net2 plus or Net2 classic control units using a dedicated CAT5 cable. One 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). Net2 Plus is supplied as a PCB only or in a cabinet with or without a power supply. Both metal and plastic cabinets are available, with a 2A or PoE+ power supply. Both metal and plastic cabinets are available, with a 2A (battery backup recommended) or PoE+ (UPS recommended) power supply. This product is a suitable alternative to the Net2 Entry – Control Unit, when combined with any 802.3af or 802.3at (PoE+) compliant 3rd party PoE switch. We recommend the TP Link TL-SF1006P switch which has been thoroughly tested with the Entry system.
