fitted with metal or metalized connector
shells. Shielded cables and connectors
are required to prevent radiation and
reception of electrical noise.
To minimize electrical noise pickup in the cable:
•
Keep data cables as short as possible.
•
Do not bundle the data cables tightly with the power cords.
•
Do not tie the data cables to power wire conduits.
NOTE: Zebra printers comply with FCC “Rules and Regulations,” Part 15,
for Class B Equipment, using fully shielded data cables. Use of unshielded
cables may increase radiated emission above the Class B limits.
