Starting Up
Be sure to follow these steps when turning on
the power.

turn the Network 3 Controller ON.
When the Switch is illuminated, power is
ON. When the Switch is not illuminated,
the power is OFF. (Push the Switch again
to turn the Controller OFF.)
2. Turn all other optional equipment
(printers, etc.) ON.
3. Turn the CENTRAL COMPUTER ON (see your
Computer's owner's manual for specific
instructions).
4. Turn the AUXILIARY COMPUTERS ON.
5. Push the Controller's MODE Switch for
either Automatic or Programmable control.
•
When the Switch is illuminated, the
Controller is in Automatic Mode.
•
When the Switch is not illuminated, the
Network 3 is in Programmable Mode.
You
are now ready to begin working with
your Network 3 Controller system.
Using the
Controller
Once the Controller is properly connected and
the power is on, you'll find the Network 3
System extremely simple to use since there's
only one switch to press - the MODE Switch.
The Controller is in Automatic Mode when
the
MODE Switch is illuminated .
When the MODE Switch is not illuminated, the
Controller is in Programmable Mode.
Automatic Mode
When the MODE Switch is lit-up and the
Network 3 is set to Automatic mode, the
Controller automatically checks (polls) each
AUXILIARY COMPUTER until it finds a student
who is requesting help.
The Controller then notifies the CENTRAL
COMPUTER,
which asks the student what kind of
help he/she
needs (whether saving, loading, or
printing out data or programs). When the
student is finished, he/she must "release" the
CENTRAL COMPUTER. (In Auto Mode, the specific
command
which the student uses to release the
CENTRAL COMPUTER depends upon the program
the student is running at the particular time.)
The Network 3 can continue polling only after
the student has released the CENTRAL
COMPUTER.
Note: The Color Computer cannot b.e used in
Automatic Mode.
