1-32 Chapter 1: Product Overview<br />
Power Supply<br />
The terminal uses an AC adapter for its power supply, concealed in the<br />
terminal mounting. The supply is inaccessible when the terminal is in<br />
the normal operation and mounting position to prevent tampering,<br />
and is sealed to help protect against spills or other environmental<br />
hazards.<br />
Note: The power supply automatically senses the proper AC voltage;<br />
therefore, only normal servicing access is required.<br />
• All power required to operate the base unit, PCMCIA option and<br />
PCMCIA cards, speaker option, scanner option, and bus-powered<br />
USB peripherals is provided by the power supply.<br />
• The Processor Board serves as the hub to distribute power to all<br />
terminal functions. Cash drawers, VFD customer display, PS/2<br />
keyboard, PCMCIA daughter board and slots, scanner (through<br />
RS-232 port), USB, hard disk, and LCD all receive power through<br />
their respective Processor Board connectors.<br />
• Printers requiring 24V are not supported by the <strong>7455</strong> power supply<br />
but can be used if they are powered with an external power supply.<br />
Note: The power available to peripherals depends on the<br />
configuration of the base terminal and the power required by the<br />
peripherals. Careful consideration of the power demands of the system<br />
should be taken to ensure it does not exceed that provided by the <strong>7455</strong><br />
power supply.
