To reset the unit to DHCP, power up with
the reset button held down until the unit
beeps. The interface is now fully reset
and will now operate in DHCP mode.
1. Power (Green) - 12V power LED.
2. Termination (Red) - The on-board resistors are in place across the RS485 data pairs.
3. Rx (Red) - The interface is receiving data (RS485).
4. Tx (Green) - The interface is sending data (RS485).
5. Server Connected (Green) - The TCP/IP interface is communicating with the PC Net2 server.
6. Server Link Green = 100 Mbit/s : Orange = 10 Mbit/s (TCP/IP speed).
**IMPORTANT**
Apply power to the unit after connecting
the RJ45 plug to a network point.
This device requires Net2 v4.07 or later to operate.
Earlier Net2 software is not compatible with this unit.
If your PC can only support Net2 v3 software, please
contact Technical Support for further advice.

The Net2 TCP/IP Ethernet Interface allows a Net2 data line to be controlled from a PC running the Net2 Server
across a TCP/IP Ethernet network.
There is a 1 km maximum length for a data line. This can be increased by using Net2 RS485 high speed repeaters
(477-836) or by creating multiple data lines using several Ethernet connections controlled from the one PC.
The data line must be wired in a single daisy chain. The data converter may be located anywhere along the data
line. 120 ohm terminating resistors must be linked across each data pair at the beginning AND end of the line.
This can be done on many units with a switch or jumpers. If not, free resistors are provided with the converter.
This unit has termination resistors that may be brought in circuit by means of a slide switch.

When connecting to a LAN
The IP address should be assigned a xed value, or should be given a DHCP reservation. Unreserved IP addresses
issued by DHCP servers are not guaranteed to be constant, leading to potential failure of communication between
Net2 software and the device.
Run the Net2 Server Conguration Utility (Start/Programs/Net2) and Click on TCP/IP nodes.
Click on;Detect and the MAC address of the device(s) will appear in the table. You must then use the "IP address
conguration" tab to manually assign the IP address, subnet mask and gateway.
Be aware that if the IP address that you give the device is not in the same IP range as the PC, the device will no
longer respond until you connect to it with a PC that is in the same IP range.
Some rewall/virus protection software and other wireless hardware can block the IP detection process. Disable
these and try to detect the device again. Please contact Technical Support if you require further advice.
Page 3
If you detect the MAC address but the device now shows 'Not Responding', you must 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 IP address of the
PC or the IP address of the device 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, ensure that the following ports are open on all devices
between this unit and the Net2 PC:-
9999 TCP
10001 TCP
30718 UDP
If you still cannot detect the MAC address of the device, call our Technical Support Help line.
Connecting to a WAN or different subnet mask
If you are connecting this device to a remote subnet which is different from the Net2 software PC, the standard
detect mechanism cannot work across the network routers between them. The IP address, along with the correct
subnet mask and gateway for the remote subnet have to be set. Either do this on the local subnet with the
existing Net2 PC, or use a PC on the remote subnet once the device is installed.
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 congured between the networks. Again, this would be done by
the Network administrator of that site. Make sure the ports listed above are open on all intermediate routers.
Once installed, create a record with the;Add button (if none was created during initial set up) and you should then
be able to detect its MAC by entering the IP address in the Conguration screen Ping box.
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. 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 nding process.
TCP/IP Loopback test
The following test should be run if there are problems setting up the IP conguration of the interface. This test
sends data to the device and checks this against the data it receives back. This conrms that the network is
working correctly.
The Net2 server program must be shut down during this test.
Remove any wires from the RS485 data line connector and create a hardwired data loop as follows. Connect
the Orange to White/Green and Green to White/Orange. To run the test, go to Net2 Server Cong Utility/TCP/
IP Nodes/Advanced and click on Loopback test. If the test fails, connect the unit directly to the PC with an RJ45
patch cable and test it again. Should this still fail, please call Technical Support for further advice.
