Magnetic Stripe <strong>Re</strong>ader<br />

A 3-track MSR head is available as an option. The ISO and JIS card<br />

formats are supported.<br />

When card data is read, an interrupt is generated. A software device<br />

driver for the MSR must be loaded to allow the application to process<br />

the data.<br />

Optional Touch Screen Controller<br />

On NCR <strong>7455</strong> <strong>Re</strong>tail Terminals that contain the optional touch screen,<br />

the MicroTouch ® “Excalibur” chip is used to interface the touch panel.<br />

This controller supports the MicroTouch 5 wire resistive panel.<br />

In order to save an RS-232 port, the touch data is delivered to the<br />

system through the PS/2 interface. This requires a mouse-aware touch<br />

device driver for the appropriate OS.<br />

Note: The <strong>7455</strong> does not support PS/2 mouse devices on units that<br />

have the optional touch screen because the touch screen uses the PS/2<br />

port.
