1-30 Chapter 1: Product Overview

POS Connector Board

The POS Connector Board is a small daughter board that mounts directly on the Cash Drawer and Parallel Port header. Connectors on the edge of this board form a second connector row above the Processor Board connectors. Connectors are available for two cash drawers, a customer display and a microphone.

Power for the cash drawers (24 V) and VFD customer display (5 V and 12 V) is supplied by the Enhanced Power Supply through the parallel connector.

Motion Sensor

The terminal hardware can detect movement near the terminal and enables software to prompt system operation from a low-power state. Application software may also be able to make use of motion detection when in the ON state if it is enabled by lower-level software.

Motion is detected as a change in ambient light level that is greater than a software-controlled threshold.

A photodiode mounted behind the front bezel of the unit senses ambient light levels. The photodiode resides on a small circuit board (the Motion Sensor Board). A harness connects the Motion Sensor Board to the amplifier and motion sensing logic on the Processor Board. The user Power/Status LED indicator shares this board.
