TCP/IP-CRC220 TCP ADAPTOR INSTALLATION
DOC0081 V1.2
Description
The TCP/IP220 is a daughter board that can be fitted to either a CRC220 PCB or a CRC221 PCB.
This enables TCP/IP communications to the Norpass3 hosting PC, effectively replacing the integral
RS485 communications interface. Once fitted, the TCP adaptor can be connected to a network point
using a standard Ethernet patch cable (see ‘Setting Up a TCP/IP Connection’ for network settings).
The adaptor also facilitates an RS485 bus to allow other controllers to be linked to the TCP port in a
daisy chain, thereby enabling the management of them by Norpass3 via this network port.
Fitting Instructions
ATTENTION
Observe precautions for handling ELECTROSTATIC SENSITIVE DEVICES
Three nylon circuit board supports are supplied with the adaptor to secure it in place on the
controller PCB. Electrical connection between the two boards is provided by 10 pins on the
controller connected to an 10-way socket on the underside of the adaptor PCB.
Fit the adaptor as follows :-
1
Check that the RS485 terminal
connector block is not fitted,
and remove all jumpers from the
RS485 interface.
2
Fit the 3 circuit board supports to
the adaptor PCB as shown on the
right.

3
Carefully engage the connector block on the underside of the adaptor PCB with the dual row
of pins on the controller PCB (do not push it all the way down at this stage). Align each of the 3
nylon supports with their corresponding holes in the controller PCB.
4
Push the adaptor PCB firmly until all 3
supports have clicked into place. Ensure that
the connector is fully engaged by pressing
firmly on the centre of the adaptor PCB.
5
Fit the RS485 terminal connectors to the terminal
pins on the adaptor. If the TCP adaptor is going
to be at one end of an RS485 daisy chain, ensure
that the terminal resister jumper is fitted.
Setting Up a TCP/IP Connection
Preparation
Before you start, make a note of the MAC address (physical address) of the device. This is printed on
the label on the thin server and appears something like: 00-80-A3-00-00-F8.
You will also need to run the Lantronix Device Installer program on a PC connected to the network.
The program is supplied on the Norpass3 disk or you can download it from:
http://www.lantronix.com/support/downloads/?p=DEVICEINSTALLER
Setting Up the Device
For Norpass3 to communicate with the TCP/IP adaptor, you need to add a corresponding TCP/IP
port to Norpass3, which requires the IP address and Port number of the adaptor. Each adaptor is
factory set to obtain an IP address automatically, and the Port number is set to ‘10001’. There are
two ways in which to assign an IP address to the adaptor depending on the customer’s network:
0

Where The Network Uses DHCP To Assign An IP Address To A Connected Device
While the controller is powered down, use a standard Ethernet cable to connect the device to a
network port and then power up the controller.
Within a few seconds, the DHCP server will detect the device and assign a free IP address to the
device. You now need to find out which IP address has been assigned.
Connect your PC to the network and run Device Installer. The program will identify all Lantronix
devices connected to the network and display them as shown here:
Look for the MAC address of your device in the device list and make a note of the IP address that
has been assigned to it. You now have the information that you need to add the port to Norpass3.
Note: We recommend that you arrange with the Network Administrator that each device always
receives the same IP address (Reservations). This will prevent any future disconnection
and connection of devices on the network causing a new IP address to be assigned to this
device, which would then require an update to the settings in Norpass3.
If this is not possible, we recommended that you use Device Installer to assign a fixed IP
address to each device (see below).
Assigning A Fixed IP Address To The Device (Recommended)
While the controller is powered down, use a standard Ethernet cable to connect the device to a
network port and then power up the controller.
Note: If you wish to connect to the TCP/IP-CRC220 device directly from your PC, remember to use
a cross-over cable instead of a patch cable.
If DHCP is enabled on the network, the device will be automatically assigned an IP address on that
network (see above).
Run the Device Installer. If DHCP is enabled, the device will be shown with a valid IP address against
the MAC address. Otherwise it will be displayed in red with the comment ‘unreachable’. The device
will be assigned a default IP address from the range 169.254.x.x.
Choose an unassigned IP address on the network (check with the Network Administrator for
available addresses). Select ‘Assign IP’ from the toolbar. Choose ‘Assign a specific IP address’ and
follow the instructions to add the required address and subnet mask.
Once you have completed the procedure, click ‘Search’ on the Toolbar. The device should now be
listed with the correct IP address. You are now ready to add the corresponding port to Norpass3.

Note: If you experience problems with the setup, you may have inadvertently altered one or more of the
settings. It is recommended that you reset the settings to the factory default and start again. To
reset to the factory settings, please follow the procedure described in the following document:
http://www.nortechcontrol.com/media/40175/lantronix-device-default-settings-for-crc220.pdf
Adding the Network Port to Norpass3
In Norpass3, choose ‘Communication Ports’ from the Installer/System Settings menu. The Comm
Ports screen is displayed.
To add the port, click on ‘Add new port’ from the ‘Tools’ pane on the left. The right-hand pane is
enabled for editing:
Fill in the appropriate details as follows:
Give the port a descriptive name, select ‘TCP’ in the ‘Type’ box and enter the IP address of the
device and the port number (10001). Once the port has been configured, tick the enable box to make
it active.
Click the save (diskette) button in the bottom left of the window.
Click the ‘Done’ button when complete.
Finally, select the controller associated with the adaptor and set it’s Comm Port to the one that you
have just added. You must also select each controller connected to the adaptor via RS485 in turn
and set their Comm Port in the same way.
