Do not press the reset on the card containing the ACTIVE controller after
plugging in the IDLE controller. It takes several minutes to download the
database. If the reset is pressed during this time ALL DATABASE SETTINGS
WILL BE LOST, and the default database loaded.

In Normal mode, the way in which the control card operates is dependant on the
protocol defined for each of the general remote ports.
For instance, if one of the General Remote ports is configured to support
multi-drop
comms protocol
then, from this port’s point of view, the controller is acting as a basic
system controller.
If, on the other hand, one of the general remote ports is configured to support
General Switcher Protocol then, from this ports point of view, the control card is
acting as a local controller for a router. It will be controlled by a more intelligent
control system. The remainder of this chapter considers normal operation in detail.
But first a description of the Special Test mode.

The two following block diagrams illustrate typical set-ups for
Freeway
. The way in
which the system operates is wholly dependant on the configuration of the general
remote ports. The first diagram shows Freeway behaving as a router, being controlled
by an external control system. The second illustrates Freeway configured as a basic
system controller, where two of the General Remote ports are configured as multi-
drop panel ports and the RS232 port selected to be the Editor/configure port.
