Using the Alternate Console Feature
Connecting a
Terminal as
an Alternate
Console
To connect a terminal, follow these steps:
1.
Halt the system by pressing the halt button behind the front
door of the system unit.
2.
Turn off (O) the system unit.
3.
Move the alternate console switch behind the door on the
front of the system unit to the up (on) position using a small
pointed object. (Do not use a pencil; the graphite will damage
the switch.)
When the switch is in the up position, the terminal functions
as an alternate console. The printer/communications serial
port is now a terminal port.
4.
Attach one end of an RS423 serial cable to the printer/
communications port on the back of the system unit and
the other end of the serial cable to the serial port on the
alternate console terminal.
5.
Turn on ( | ) the terminal.
6.
Check the baud rate of the terminal, which should be set to
9600 baud. See your terminal documentation for additional
information on adjusting the baud rate.
7.
Turn on ( | ) the system unit.
8.
Adjust the brightness and contrast on your terminal.
9.
If the console prompt
(>>>)
does not appear on the alternate
console screen, press the Break key on the alternate console
terminal keyboard.
If it still does not appear, call your Digital service
representative.
