MAGNETIC OPTION CARDS
Horizontal Magnetic and MICR interface cards for managing the optional magnetic units can be connected to the
motherboard:
• Horizontal magnetic unit - interface card code XYAB3124 - to connect to the special connectors on the
motherboard;
• MICR unit - interface card code XYAB1564 - to connect to the special connectors on the motherboard.
Horizontal magnetic unit
This device can read/write horizontal magnetic stripes. It consists of a mobile magnetic printhead that operates
across the insertion slot with a specific controlled-movement mechanism.
It operates across the entire insertion slot of the printer and does not involve any particular constraints as regards
positioning of the passbook inserted.
The operation on the stripe is carried out exerting controlled pressure on the passbook to guarantee uniform
distance between the printhead and the magnetic support.
