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.
