Configuring a Net2 plus using TCP/IP
Connecting Net2 via TCP/IP networks
Net2 supports the connection of control units to the Net2
server over RS485 data lines and also via nodes on TCP/IP
Ethernet networks. This greatly increases the flexibility of
installation options.
The diagram shows a Net2 system communicating over a
LAN network using Net2 plus ACU that combines a TCP/
IP converter with a door controller. This requires v4.14
software or later.

Net2
AN1006
What hardware do I need?
The Net2 server PC can communicate with its' door controllers over the users network via a LAN, WAN or VPN
connection.
The Net2 485 TCP/IP Ethernet Interface is a complete unit with power supply that converts TCP/IP data into RS485
allowing for the connection of a Net2 data line to a network.
The Net2 plus control unit plugs directly into a standard TCP/IP network connection. It can run as a standalone
controller and also drive an RS485 data line of other Net2 units.
Up to 200 control units can be connected to the RS485 data line. This data line must be terminated with 120 ohm
resistors switched or wired across both data pairs at each end.
The interface unit may be located at any position along the RS485 data line.

For earlier designs, see the following:
Instruction: Ins-30032 - Paxton Net2 Ethernet Interface. < http://paxton.info/819 >
Instruction: Ins-30029 - Net2 485 TCP/IP Lantronix UDS10B Ethernet Interface.
< http://paxton.info/820 >
Software configuration
The TCP/IP Ethernet interface is configured using the Net2 Server Configuration Utility, by selecting the TCP/IP nodes
tab. Depending on the specific details of the Ethernet network, you may be able to detect the Ethernet interface,
simply by clicking Detect. If this doesn't find it, then you will have to Click 'Add' and enter the MAC Address manually.
The unit supports DHCP, which means that a DHCP server can issue its IP address. A static IP should be assigned
once the device has been allocated an IP address via DHCP. A reservation should be made in the DHCP server, to
ensure that the same IP address is issued each time, should the unit be reset. Consult your network administrator on
detail of how to reserve IP addresses. The unit's MAC address can be read from inside the plastic enclosure, and will
be required by the Network administrator to enter the reservation.
The list box, at the top of the TCP/IP nodes tab, will list all of the units that have either been found or manually
entered. There is a check box next to each entry, which allows each unit to be enabled or disabled.
You can test that the units are responding, by selecting them and clicking the Ping button.

How to assign a static IP address to an ACU
If the Ethernet network does not have a DHCP server, then the IP address must be set manually, using the Net2
Server Configuration Utility. Select the IP address configuration tab. The network administrator should be able to
advise you on suitable values to use. Check the 'Use the following IP address' button and enter the chosen address in
the box. This will fix the IP address of the interface.
Naming TCP/IP Ethernet interfaces
The rename button can be used to give an interface a meaningful name in the system. This can be especially useful
when more than one interface is used, as the name will appear in the doors screen within Net2 showing which
ACU's are connected to which data line, helping in any future fault finding process.
Advanced tab of config utility
Network latency can be amended for sites with slow or busy TCP/IP networks. The advanced options should only be
changed following advice from Paxton Technical Support

Net2
AN1006
VLAN recommended
On sites with high levels of broadcast traffic (CCTV, etc) this option is highly recommended and should be
implemented wherever possible. VLAN's allow administrators to set up their networks by logically grouping devices.
IP addresses, subnet masks, and local network protocols require fewer local server resources in this environment.
Services can be more effectively deployed when they span buildings within a single VLAN. See also: AN1085 Recommendations for using Net2 with LAN and WAN networks. < http://paxton.info/970 >
Connection over a Wide-Area Network (WAN)
If you are connecting the interface to a WAN or to a network with a different subnet from the server running the
Net2 database, you must first fix the remote IP address, subnet mask and return gateway in the unit before taking it
to the remote site.
The PC that has the Net2 server installed must be able to access the IP address range on the WAN\remote site. This
may require the routers and gateways to be configured between the networks. Again, this would be done by the
I.T\Network administrator of that site.
Once installed, use the add button to create a record in the nodes table (if none was created during the initial setup)
and the device can be assigned it appropriate IP information as designated at the remote site.
Connecting to the PC directly
The Net2 plus unit can be connected to the PC via a standard network patch cable.
Troubleshooting
If you detect the MAC address but the device now shows 'Not Responding', check the IP address to make sure it
is still in range with the PC or network. If it is not, you should either change the PC's IP address or the Ethernet
interface's IP address so they are both again in the same range. Our Technical team can talk you through this if you
need help.
If the MAC address does not appear when you click 'Detect' then you will need to check that the following ports are
open:9999
TCP
10001
TCP
30718
UDP
If you still cannot detect the MAC address of the Ethernet interface then connect it directly to your PC via a patch
cable and call our Technical Help line.
