Paxton Net2 plus Manual page 2

Overview
A Net2 plus can connect to the Net2 PC using either an un-shielded RJ45 patch cable or an RS485 data line. This
greatly increases the number of installation options available to the installer.
One Net2 plus can also be used as the TCP/IP interface for an RS485 daisy chain of Net2 plus and Net2 classic units.
When used with a TCP/IP connection, it must first be detected using the Net2 Server Configuration Utility as defined
later in this instruction.
When used with an RS485 data line, on-board termination resistors can be put in circuit with a simple slide switch.
Ensure that units installed in the middle of the data line have this switch turned OFF.
A dedicated Intruder Alarm connection is provided.

Here are two typical site layouts.
1 - The Net2 plus ACU's can be individually connected to the Net2 PC via the site LAN network.
2 - The Net2 plus ACU can be used as the TCP/IP converter for a line of Net2 plus and Net2 classic ACU's.
The TCP/IP interface allows an RS485 data line to be controlled by the Net2 Server running across a LAN network.
An RS485 data line has a 1000 yds maximum. This distance can be increased with the use of Paxton high speed
repeaters or by using shorter independant data lines using multiple LAN connections controlled from the same PC.
The ACU shall be installed within the protected premises as both the power and lock wiring is present at the PCB.
A Tamper alarm input is provided on the PCB - See Input/Output Wiring
The ACU's will continue to operate in a 'standalone' mode if the PC is shut down or the dataline is disconnected.
Any Events that occur during this period are stored in the ACU and the PC is updated when it comes back on line.
The PC must be running for any 'server based' functions to operate. (Antipassback, Time and Attendance, etc).
TCP/IP and RS485 LED indication
The Net2 plus performs two functions. It is an access control unit and also a TCP/IP RS485 converter. Information
can pass across the PCB between the TCP/IP and RS485 data port but is not relevant to this ACU
- Server Connected LED (Steady Green)
This LED shows that the TCP/IP interface is active and receiving data from the Net2 PC server. This includes all data
for other ACU's that may be linked via the RS485 data port.
- Rx and Tx LED's
These LED's show the activity for this ACU only. This is same indication as seen on a Net2 classic ACU.
It is not dependant on the source (TCP/IP or RS485). The Rx LED will flash for all data being received and the Tx
LED will only flash when this unit responds to its own address.
