1.
Set the ON/OFF switches on all printers, expansion boxes, terminals,
and other peripherals to the OFF (0) position.
2. Set the ON/OFF switch on the system unit to the OFF (0) position.
3. Connect the 50-pin connector of the synchronous cable to the
synchronous port on the rear of the system unit. See Figure C-3.
