names by Crimson when they are created. These names may be changed by selecting the
appropriate icon in the left-hand pane, and simply typing the new device name.
ETHERNET CONFIGURATION
The Master’s Ethernet port is configured via the Ethernet icon in the left-hand pane of the
Communications window. When this icon is selected, the following settings are displayed…
IP PARAMETERS
The Port Mode field controls whether or not the port is enabled, and the method by which the
port is to obtain its IP configuration. If DHCP mode is selected, the Master will attempt to
obtain an IP address and associated parameters from a DHCP server on the local network. If
the unit is configured to use slave protocols or to serve web pages, this option will only make
sense if the DHCP server is configured to allocate a well-known IP address to the MAC
address associated with the unit, as otherwise, users will not be sure how to address the
Master!
If the more common Manual Configuration mode is selected, the IP Address, Network Mask
and Gateway fields must be filled out with the appropriate information. The default values
provided for these fields will almost never be suitable for your application! Be sure to consult
your network administrator when selecting appropriate values, and be sure to enter and
download these values before connecting the Master to your network. If you do not follow
this advice, it is possible—although unlikely—that you will cause problems on your network.
IP ROUTING
The IP Routing option can be used to enable or disable the routing of IP packets between the
Ethernet port and any PPP connections made to or by the Master. You should not enable this
option unless you understand the implications of allowing such routing. Please refer to the
Advanced Communications chapter for more information.
PHYSICAL LAYER
The Physical Layer options control the type of connection that the Master will attempt to
negotiate with the hub to which it is connected. Generally, these options can be left in their
default states, but if you have trouble establishing a reliable connection, especially when
