The ac power outlet (mains) must have a protective
earth (ground) terminal. Serious shock hazard leading
to death or injury may result if the plotter is not
properly grounded.
Choosing an Interface Cable
(Instructions ' User's Guide, chapter 1, w Connect the plotter to your computer.)
Serial (RSĆ232ĆC) Interface A short cable (less than 15 meters or 50 feet) is recommended
for the RSĆ232ĆC interface. A longer cable is permissible, provided the load capacitance does
not exceed 2500 picofarads.
Parallel (BiĆTronics/Centronics) Interface Use a short cable (less than 2 meters or 6.6 feet)
for the parallel interface.
