This menu lets you change the assignment of each button on an attached CC-
300 unit. If you have multiple CORIO2 units attached to a CC-300, then it is
advisable to set them all so that their buttons act in the same way for all units

Items associated with the Adjust ethernet group
(Please note that not all units have this sub-menu.)
Your unit can be remotely controlled via its RS-232 serial port, but some units
can also be controlled via a Local Area Network using the Ethernet connector.
This provides TCP/IP communications to and from the unit using a custom
protocol.
In most networks, all computers and other electronic equipment will have a
dedicated connection to a network hub or switch, with each item having its
own ‘IP address’ (Internet Protocol address). This is the unique set of
numbers that identifies the item on the network.
The network itself is usually segmented into a number of sub-networks. Small
offices will generally just use one sub-network, with larger ones running many
sub-networks that are linked together across a sub-network bridge. Sub-
networks are split up by assigning different ranges of IP addresses to the
different sub-networks. The ranges are defined by the ‘sub-net mask’.
In very simple setups with 2 pieces of equipment (e.g. a computer and one
other piece of equipment), it is possible to link the two together using just a
cable (which must be a cross-over cable). However, this setup is rare.
Where only a single sub-network exists (as in the majority of cases) it is vital
that:
1. All equipment has different IP addresses.
2. All IP addresses are part of the same sub-net.
3. All equipment has the same sub-net mask.
In most situations the computer will already be attached to a network, and
therefore its IP address and sub-net mask will be easily accessible (e.g. in
Windows XP you can right-click on the network activity icon to see the
Support status, or check the Network Connections in the Control Panel and
right-click the ‘Local Area Connection’).
An IP Address then needs to be assigned to your unit. Typically this will be by
changing the last of the 4 values (that are separated by dots) to one that is not
yet in use. The ‘IP add’ menu item is used to enter this into your unit.
