Research Activities
Research:
Internet and Advisors
Transmitter/Receiver – located and purchased online
Relays – located and purchased online
Micro-controllers – used ISUs HC11
Sensors – Door Store, Previous Lab Projects
Free Door Opener:
Sears 1/3 H.P. Rail type - Chain driven
Manufactured in 1992
Not Compatible with Recent Obstruction Sensors
Technical Approach
Garage Door Scenarios:
Input
Remote Controller Signal
Main Controller Signal
Open Indefinitely
Keypad Signal
Open Indefinitely
Immediate Close

Implementation Activities
Problems Encountered:
Downloading Code to Motorola HC11E9 EVBU Board
Switched to Motorola F1HC11 Board that was used in Cpr E 211.
Important Part of Magnetic Sensors Missing
Part Built into Genie Systems. Changed to Contact Limit Switch.
Obstruction Sensors Not Compatible with Door Opener
Eliminate Obstruction Sensor as input to SGDS because of FCC
Regulation in 1993.
Testing and Modifications
Testing:
SGDS Broken into 7 Different Individual Tests
Tested as whole afterwards
Test 1 – Transmitter and Receiver:
Apply Power, Measure Output at Relay
Test 2 – Momentary Push Buttons:
Figure out Wiring Scheme
Test 3 – Relays:
Apply 5V to Coil and use Ohmmeter to test the resistance between
NO and the Com terminals
…Testing and Modifications
Test 4 – Garage Door Opener:
Power Opener and Determine Terminal Functionality
Test 5 – Light Detection Circuit:
Build Circuit from Schematic and test with a flashlight to see if the
Voltage Signal disappears when incandescent light is visible.
Test 6 – Contact Limit Switch:
Wire a series circuit and make sure the NO circuit changes to closed
the the contact is closed.
Test 7 – Micro-Controller:
Download the program to the hardware, send in input signals with a
source to different pins and check the output for a signal.
