Schematic / Specification for a
9 Pin "D" to 8 Pin "MiniDin"
for use with the Kodak DC240 Digital Camera
Being that I want to be able to unload the photos to a number of different computers, I was in need of more serial cables. The alternative would have been that I would need to carry the cable with me whenever I switched computers.
I found in my cable box, a number of old "Mac" serial cables, which had a large 25 pin "D" connector at one end, and a "MiniDin" 8 pin connector at the other end.
This cable would NOT work as it was wired, so I removed the larger 25 pin "D" connector, and soldered on a smaller 9 pin "D" female connector in the following configuration:
NOTE: Using the chart below, I only connected the wires / signals detailed in " blue".

The "Mac" cable I used, has a "braided shield" on the outside of the wire bundle. I connected this sheild directly
to pin #5 of the 9 pin "D" connector.
At the other end, this same "braided shield" is connected to the "outside" of the "MiniDin" connector.

The cable detailed in the chart above does NOT have the exact wiring configuration as the cable supplied with the
camera.
The supplied cable also has a wire from the 9 pin "D" pin #6
to pin #7 on the 8 pin "MiniDin" connector.
The "Mac" cable I used did NOT have a wire connected to pin
#7 on the 8 pin "MiniDin" connector.
Not having this wire in the circuit does not affect the performance of the camera system, or it's ability to
download the photos to the computer.
As well, the cable from Kodak does have a "Toroidal Choke" intergrated into it, which the cable I built does not.
