Aurora H2O User’s Manual 5
Chapter 4. Programming Advanced Features
4.2.3 Connecting to an Ethernet LAN
The Ethernet option supports the 10Base-T and 100Base-TX twisted-pair Ethernet standards. Screw terminal
connectors are provided on the Aurora Terminal Board for connection to the LAN. The Ethernet cable should be
inserted into an available cable gland, and fed through the increased safety compartment to the terminal board. The
cable should be prepared as described in Step 6 on page 17 .
To access the Ethernet Settings menu, enter your User passcode ( 2719 is the default). To
activate the Ethernet port, select the Status option and press Enter . The following screen
appears.
When the Status is set to Disabled , power is removed from the module, effectively
unplugging it from the Ethernet network. If the Status is returned to Enabled , there will be
a delay of up to one minute before the module completes its Power On Self Test
( POST ) and becomes visible on the Ethernet network. After selecting the desired
option, press Enter . [Note that the Disabled option is the default setting.]
IMPORTANT: If the Ethernet Settings menu is “gray” or missing, your Aurora does not have
Ethernet capability.
Selecting Factory Reset from the Ethernet Settings menu returns the Ethernet module to its
default state, which takes approximately 15 seconds to complete. After a Factory Reset ,
the module enables DHCP, reset passwords to their defaults, disables Modbus/TCP,
and enables RealPort (serial emulation) mode. After a Factory Reset , it is necessary to
log in via the HTML or Telnet command interface, and reconfigure the network and
Modbus settings (see Appendix B. “Aurora H2O Ethernet Operation” for
detailed instructions).
4.2.4 IP Address Assignment
By default, Aurora uses the Dynamic Host Configuration Protocol (DHCP) to obtain an Internet Protocol (IP) address
from the network controller or router. If a DHCP server is not available, a static IP address must be selected and
assigned. This is performed via the HTTP or Telnet interface.
If an IP address is obtained from a DHCP server, that server may be used to identify the IP address assigned, or the IP
address may be determined with a Device Discovery Utility .
If no DHCP server is provided, after several minutes the Aurora will default to a Link Local Address per IETF RFC 3927.
The Aurora will assign itself a random IP address in the range of 169.254.1.0 - 169.254.254.255.
