In this posting we will start the preparation work of the original flight hardware. The VHF COMM radio head that I picked for the Lockheed L-1011 project has two drum digits and a diode board that allows selection between the active and the passive frequency. The IO interface needs to connect to several elements in the original flight hardware:
- frequency toggle switch
- diode board for the drum encoded frequencies
- Instrument illumination
- light plate illumination
Step 1: We will remove the original connector from the housing. The IO board will sit right behind the connector and we will feed the necessary cables through the opening left behind by the connector.
Step 2: Open the cable ties and remove the diode plate so that we can remove the cables that originally ran between the board and the connector. These cables will be replaced with cables to the I/O board.
Step 3: Remove the original cables.
Step 4: Re-drill the connectors ... here is the finished cleanup work for today.
