1-32 Chapter 1: Product Overview

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.

Integrated Speaker Module (Optional)

The Integrated Speaker feature provides two stereo speakers that attach to the bottom of the Core Module. The maximum output of the speakers is approximately 6 watts per channel.
