Configuring System IP
Addresses
Caution! Your system has been pre-configured at the factory for a default IP
address of 192.168.1.160. Incorrect editing of network files will cause system
malfunction. Please consult Wheatstone support if you are having trouble connect-
ing your system to a network.
Overview
In order to communicate to the E-WHEATNET over ethernet, appropriate network
parameters must be loaded. Constraints on the router configuration were made to
simplify the installation, while still providing the flexibility to connect the router to
existing customer networks. They are:
1. The router and any attached GUIs must exist on the same subnet. The router has
no ability to route across subnets.
2. If dynamic address allocation is used on the network (e.g. DHCP), the router must
be given a “permanent” address allocation. In order to allow the router to run on simple
networks or at sites with little system admin support, dynamic address allocation
schemes (such as DHCP or BOOTP) were not used to provide an IP address to the
router.
Editing Network Parameters
The E-WHEATNET stores its network IP address and subnet information in a
simple text file on its flash hard disk. Changing the E-WHEATNET’s network
parameters requires the user to download the xp_net.txt file via FTP from the E-
WHEATNET, edit as required, then move the edited file back onto the E-WHEATNET.
Once the editing process is complete, a system re-boot will initialize the new addressing
scheme.
Setting up FTP Site Profiles
Typical FTP clients allow the user to create Site Profiles for frequently visited FTP
sites. These site profiles store log-on information and site location information that
would otherwise have to be entered every time you access the site. The E-WHEATNET
is a “site”. Required profile information is:
Site Name - identify the CPU you are connecting to (e.g. “E-NET”)
IP address of FTP site (E-WHEATNET default 192.168.1.160)
User Name = knockknock (lower case)
Password = whosthere (lower case)
Open the third party FTP application and create a site profile for the E-WHEATNET’s
CPU using the current IP address (default is 192.168.1.160).
We recommend the freeware FTP client FTP Surfer by Whisper Technology.
Windows Internet Explorer allows FTP, but in our experience it is not the best choice
for this file maintenance application.
