Power Supply
The terminal uses an AC adapter for its power supply, concealed in the
terminal mounting. The supply is inaccessible when the terminal is in
the normal operation and mounting position to prevent tampering, and
sealed to help protect against spills or other environmental hazards.
Note: The power supply automatically senses the proper AC voltage;
therefore only normal servicing access is required.
All power required to operate the base unit, PCMCIA option and
PCMCIA cards, speaker option, scanner option, and bus‐powered USB
peripherals is provided by the power supply.
The Processor Board serves as the hub to distribute power to all
terminal functions. Cash drawers, VFD customer display, PS/2
keyboard, PCMCIA daughter board and slots, scanner (through RS‐232
port), USB, hard disk, and the LCD all receive power through their
respective Processor Board connectors.
