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.
