Implementation ActivitiesProblems 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 MissingPart 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 FCCRegulation in 1993.

Testing and Modifications

Testing :SGDS Broken into 7 Different Individual TestsTested 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 betweenNO and the Com terminals


20/35

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 theVoltage Signal disappears when incandescent light is visible.

Test 6 Contact Limit Switch:Wire a series circuit and make sure the NO circuit changes to closedthe the contact is closed.

Test 7 Micro-Controller:Download the program to the hardware, send in input signals with asource to different pins and check the output for a signal.
