Pre-Set and Default Configurations
The Vanguard 100 PC must be configured to your specific application to function
properly. To help you with this activity, several pre-set configurations have been
developed which will likely meet your needs. You will find these configurations
on the CD-ROM, the Configuration Diskette, and, eventually, on the Motorola
Internet Web server. Review Chapter 5, Applications and Configurations, to
determine the application that meets your needs.
The default application for software images that support PPP and FRI will be a
PPP to FRI connection. The FRI network station is a Bypass station with an auto-
learn DLCI. The PPP will be 9600 bps. After you have installed your Vanguard
100 PC into your computer, you can ensure that you have the default
configuration by defaulting the node, as described earlier in this chapter.
If you have installed an optional daughtercard (automatically assigned to Port 1),
the defaulted node will associate the FRI port with Port 1. If there is no optional
daughtercard, the defaulted node will associate the FRI port with Port 2. The
internal Port 3, which is physically connected to your computer's COM port, will
assume the PPP role.
If your software image does not contain PPP, the next choice for a defaulted node
on Port 3 will be the SLIP protocol, then the ATPAD protocol, and finally the
PAD protocol. If your software image does not contain FRI, the default choice for
Port 1 and Port 2 will be the X.25 protocol.
Saving and Restoring Configurations
The Vanguard 100 PC allows you to save and restore a node's configuration
memory (CMEM). Saving a configuration retains a copy of your configuration on
a PC disk so you can retrieve it later, should you need to restore it. A
configuration is restored when it is retrieved from a PC disk and placed into a
node's CMEM. Restoration of a CMEM is typically used for error recovery or for
a multi- node configuration template.
The earlier part of this chapter discussed how to access the Control Port of your
Vanguard 100 PC using the commercial COM packages. From the Control Port,
you can perform the Configuration Save/Restore command.
When to Save/Restore
When a configuration is restored, the configuration in CMEM is overwritten
(except for Software Authorization Keys).
Assign each configuration a unique name so there is no confusion about
which is the correct configuration file for a node.
Save CMEM contents before performing an upgrade or replacing a bad
battery to avoid losing a configuration you may later need.
The configuration that is restored is not implemented until you boot the
node using the Node Boot command.
