Chapter 6
Using the Ethernet Interface
6-4
Make a list of all the hosts with their IP addresses that are on the same
physical network as the control coprocessor. Also, make a list of all the
hosts with their IP addresses that are on other networks with which you
will communicate regularly through a gateway. You will use this
information to update the configuration files.
The following generic network database files are included on your
software installation disk in the INET directory. Using the DOS editor
on your personal computer, update the files with information specific to
your system.
After you have updated all the files, configure the control-coprocessor
Ethernet port using the Internet Utilities of PCBridge. See page 6-12.
It is not necessary to send each file to the control coprocessor separately.
Important: The BASIC user must have PCBridge to update the
configuration files and configure the control-coprocessor Ethernet port.
HOSTS File
Change file C:\INET\HOSTS to include your system information. The
first non-comment and non-blank line is for the loopback host and should
not be changed. The lines that follow are for hosts on your network. You
list the following information for each host:
IP address
host name
full host name
aliases
(optional)
You should include the alias “localhost” for the control coprocessor.
You can organize the data either by frequency of use or in an order
designated by your network administrator. See Figure 6.1.
