Model Net2 Plus · SKU 682-493-US
One-door networked controller from Paxton’s Net2 platform. TCP/IP onboard, more doors join over an RS485 daisy chain, and the software runs on a local Windows PC with no subscriptions. Credentials are cards and fobs — including clone-resistant HID SEOS — not phones.
We install and repair access control systems across Chicago, the North Shore and the northwest suburbs — ask about the Net2 Plus for your building or business.

Net2 Plus is a one-door controller from Paxton’s Net2 platform, and its appeal is blunt: the hardware is bought once and there is no monthly bill after that. One board runs one door. The first board takes a network drop; every board after it can join over a two-wire RS485 daisy chain, so a building adds doors at its own pace — this year the lobby, next year the garage. The platform has been in the field long enough that we routinely take over systems installed by companies that no longer exist, and the boards still run. It is not locked to its own readers either: alongside Paxton’s P50 and KP75 it accepts HID or Brivo readers in Wiegand mode, and with HID readers the system takes SEOS cards, a credential that resists cloning. Management happens in Net2 software on a Windows PC in the building — functional, stable, updated when you choose. No cloud dependency, no license fees, no subscriptions.
Specs, firmware notes and availability change over time — confirm against the manufacturer’s current documentation before ordering.
The architecture takes one sentence to explain: each Net2 Plus board runs a single door — its reader, lock, exit button and door contact. The first board connects to the building network through its onboard TCP/IP port. The boards that come later do not each need a network drop; they hang off the first one over RS485, a two-wire run from panel to panel.
That daisy chain is what makes the system easy to grow. Adding a door means adding a board, not redesigning anything, and Paxton allows up to 200 networked units in one installation — far more than any property we service will use. We quote the bare board (682-493-US) where an enclosure already exists; for new work it usually goes into Paxton’s US metal enclosure with a 12/24V supply (682-610-US), or the PoE+ version (682-630-US) when the controller and lock should run off a single PoE+ switch port. Planning this out is part of our access control work in Chicago.
A large share of our Paxton calls are takeovers: a building changes management, the old security company is gone, and in the telecom closet sits a row of Net2 boards that have been switching door strikes the whole time. That is the reputation the platform earned in the field — the electronics run for years, and failures are rare enough that we remember them individually.
Reliability is also in how the board behaves when things around it fail. Every access decision is made locally on the panel, so a dead office PC or a network outage does not stop the doors — entries keep being granted and denied per the schedule already loaded. The board buffers 2,500+ events while offline and reports them back when the link returns, and its data survives a total power loss for up to 30 days.
Each board has two reader ports and speaks more than Paxton’s native protocol: clock-and-data and Wiegand are both supported, in 26-bit and custom formats up to 50 bits. The usual pairing is Paxton’s P50 proximity reader on standard doors and the KP75 keypad where a PIN or card-plus-PIN policy is wanted. But the panel is not tied to them — HID readers and Brivo readers wired in Wiegand mode work as well.
Where copied fobs are a concern, the pairing we recommend is Net2 Plus with HID readers and SEOS cards. SEOS is an encrypted credential: unlike classic 125 kHz prox, it does not give up its data to the cheap tools that clone old fobs in seconds. The HID reader authenticates the card and hands the panel a standard Wiegand read, so the panel needs nothing special — the building simply gets credentials that stay unique.
This flexibility runs both ways on upgrades. Net2 boards can go in behind readers a building already has, or the readers can be swapped later without touching the panels.
Net2 Plus does not do mobile credentials. There is no app and no Bluetooth: residents and staff carry a card or a fob, and keypad doors can require a PIN. We say this up front because it is the platform’s main trade-off, and for some buildings it is disqualifying.
For others it is the point. Nothing to install on anyone’s phone, no resident app to support, no cloud account per person — a fob works the same for every resident and every phone model, including people who do not carry a smartphone at all. Buildings that want phone-first entry should look at the Brivo ACS300 and the cloud platform behind it; we install both systems and will say directly which one fits yours.
The system is managed through Net2 software on a Windows PC in the building — that is the one piece of infrastructure this platform asks for. In return, everything stays yours: the user database, the event history and the schedules live on site rather than in someone’s cloud, and the software carries no license fee, no per-door charge and no monthly bill. The hardware is bought once, and that is the end of the spending.
It also stays out of the way. Updates are free, optional and infrequent — we see sites still running the same Net2 version we installed years ago. Capacity is generous for its class: up to 50,000 users, 250 access levels and 64 time zones per system, more granularity than most commercial buildings ever configure. When we hand over a Net2 system, the manager gets a tool they will actually use, not a maintenance obligation.
Usually, yes. The board accepts Wiegand readers with 26-bit and custom formats up to 50 bits, so HID and Brivo readers wired in Wiegand mode connect directly. We check the exact output format on site before promising a clean swap.
No. Credentials are cards, fobs and PIN codes — there is no mobile app for the door. Buildings that want phone-based entry should look at a cloud platform like Brivo; Net2’s trade-off is local control and zero subscriptions.
Nothing goes to Paxton. The Net2 software has no license fee and no per-door or per-user charge, so after the one-time hardware purchase the ongoing costs are electricity, the Windows PC it runs on and any service contract you choose.
One board per door. A new Net2 Plus joins the system over an RS485 daisy chain from an existing panel, so most added doors need a two-wire run rather than a new network drop. The platform supports up to 200 networked units — far beyond a typical building.
Doors keep working. Each board makes access decisions locally, stores 2,500+ events while offline and syncs back to the server when the connection returns. Data on the board survives a total power loss for up to 30 days.
The bare PCB (682-493-US) fits an enclosure that already exists. New installs usually get the US metal enclosure with a 12/24V power supply (682-610-US) or the PoE+ variant (682-630-US), which runs the controller and lock from a single PoE+ switch port. Same controller inside — the difference is housing and power.
If you already have Paxton hardware on site and the system is unstable, we can audit it, fix urgent issues and plan upgrades step by step instead of forcing a complete replacement. This includes systems originally installed by other vendors.
We offer free estimates for projects in our service area. New service clients also receive a 50% discount on the first service visit for troubleshooting and diagnostics, including systems we did not install.
