GENERAL FEATURES ...................53

The MCR33xx card reader/writer is a compact, versatile peripheral, suitable for the most widely

disparate applications, even in the hardest environmental conditions.

In accordance with ISO standards, the MCR33xx can record both low and high coercivity cards,

by means of a simple software-driven selection.

Available in different versions depending on the installed options, the MCR33xx can be used

manually (in desktop configuration), or in self-service applications (open frame configuration).

The desktop version is available with the external 110/230 Volt power supply unit.

Connection with the system is through an RS-232 serial interface.

INTRODUCTION AND FUNCTIONAL

DESCRIPTION

MCR33xx IN THE SYSTEM

MCR33xx

GENERAL CHARACTERISTICS

Fully controlled function by software with autotests, FW download, no jumper or setting. Specific

software and driver to test, demo, work and troubleshoot.

Shutter

The shutter (installed only in the self service configuration) is activated by an electromagnet; its

open or shut position is detected by a microswitch located on the right side of the electromagnet.

On the left side of the inlet is installed a microswitch that detects the presence of the card, while a

reading head positioned on the lower side checks the incoming card for the presence of written

magnetic tracks, to prevent objects other than written magnetic cards from being inserted into the

peripheral.

Card Transport

Astepped motor controls the transport of the card inside the MCR33xx.Three conveyor rollers,

moved by three positive drive belts, move the card over the read/write head.

Card Reading/Writing

High and/or low coercivity head mounted on a special support fastened by means of a leaf spring.

The head can read and write the tracks through a software selection; there are no jumpers or dip

switches.

High precision mechanics let the card slide over special bearings.

Power Supply

Only the desktop version is equipped with an external power supply

unit. The self service version is fitted with a 4-way connector, whose

specifications are described in the figure that follows.

INSTALLATION AND USE

POWER SUPPLY

The MCR33xx is normally factory programmed to the Customer’sorders. Any modifications to its

programming must be performed by specially qualified personnel.

Power Supply (desktop version)

·Check the power supply transformer to ensure it corresponds to the mains voltage and power

supply voltage of the MCR33xx.

·Connect the transformer to a wall outlet.

Connect the transformer cable to the MCR33xx plug.

·Connect the serial cable RS232

Power Supply (Open Frame version)

Power with +24V direct current between pins 1and 2on the 4-way connector mounted on the

electronic board (see the diagram on page 7).
