Host 10Base-T Ethernet port, RJ-45 connector
Step Procedure
1
Make sure the PC has an Ethernet NIC (Network Interface Card) installed and enabled.
2
Connect an Ethernet 10Base-T crossover cable to the HC900 controller’s Open Ethernet RJ-45 port
(top RJ-45 port).
(top RJ-45 port).
3
Connect the other end of the Ethernet 10Base-T crossover cable to the PC’s network port.

On the PC, use the Utilities Worksheet in the HC Designer software to connect to the controller over
Ethernet. Every HC900 controller is shipped with the default IP address of 192.168.1.254 and Subnet
Mask of 255.255.255.0. You can use these network parameters initially for testing or configuration
use. In the Current PC to Controller Connection Settings area of the dialog box, click on the Network
button to bring up the Network Port Properties dialog box and Add the default IP address. Be sure the
Ethernet Network Interface Card in the PC has a fixed IP address on the same subnet as the
controller (192.168.1.x, where x= 2 to 253).

Port to be used and the default IP address for the Address. Click on Loopback to assure
communications between the PC and the controller. You may now use the Ethernet port for
configuration interface.

Consult your IT systems administrator for allocating IP addresses if this controller will require a
unique IP address within a plant network. Be also sure that the PC Network Interface Card has an IP
address that allows access to the controller on the subnet after changing the controller’s network
parameters.

address that allows access to the controller on the subnet after changing the controller’s network
parameters.

You may change the controller’s IP address and related network parameters from its default using
the Utilities Worksheet in the HC Designer software. This may be done using either the RS-232 serial
port (typically used) via a null modem cable connection or the Ethernet connection from the PC to the
controller. If the RS-232 connection is desired, make sure the proper PC serial Com port to be used
has been set up (See Direct Serial RS-232 Connection above).
