This posting, is the 2nd part of the preparation work of the original flight hardware for the VHF COMM radio of the Lockheed L-1011 project. In this posting, we will connect the the diode board to a set of connectors that will later interface with the board. The picture above, is where we left of the last time, except for that I have labeled the diodes according to a specific cabling scheme. Click on the image to see the numbers.
Step 1: In the image below you will see that I have prepared two 8 position connectors with roughly 4" cables. I assume you know how to crimp the connector, so I am not showing the steps here. Each of the connectors represents 8bits ... or one byte.
To connect the VHF COMM radio, I need 16bit ... or two bytes. Therefore, we will solder two 8bit connectors into place.
Step 2: Solder the two 8bit connectors into the correct sequence on the diode board.
Step 3: Once all the cables are in place, I will remove the excess leads.
Step 4: Cable Tie the two 8bit connectors and the original cables back together to clean up the cable mess.
Step 5: Mount the diode board back into it's original position in the enclosure.
The image below shows the finished prep work for today's posting. All the cables that will interface with the I/O board will be fed through the opening left behind from the original connector.
