Elevator Position Indicator Driver -- step 1(provide driver design)-350$

1)To design a driver that decodes elevator position from different types of elevator controllers(binary,inverted binary), and sends that information serially with the minimum amount of wires possible(must be able to supply 40 units)

ALL inputs will be universal to +24 to +48vdc/-24vac to -48vdc/120vac/240vac

-0000000-1000000 latched inputs

-Door open limit input

-travel up input

-travel down input

-8 optional scrolling message inputs

2)To design a board that can be used universally on any elevator landing that decodes this information into a color screen with the floor indication. The screen will be able to display a 3 digit number and/or letters. This screen will show current floor and car travel direction. Each board will be addressable with dip switches. The arrival light will light when door open limit is active on driver and addressed board matches binary input on driver

3) there will be 8 preset optional text messages to be displayed (to coincide with the 8 inputs on driver)for example:overload, inspection, independent service, out of service, help on way

4) optional arrival gong speaker for future

5) graphic digital pattern of lantern must be able to update along with preset scrolling message
